     We are a distributor of highly engineered metal and plastic materials and a
provider of value-added services associated with these materials. Our metal
materials are commonly classified as either Ferrous (such as mild steel, cast
steel and cast iron) and Non-Ferrous (such as aluminum, cooper, brass and lead).
Our customers are a wide range of industrial companies within the producer
durable equipment sector of our economy. We are classified as being in the
metals distribution industry and we are known as a steel service center. We
deliver highly engineered materials for critical applications where exact
conformance to specifications provided to us by our customers is essential.

     Our customer base includes a variety of companies in the durable goods
industry spread across the entire spectrum of the metal using sector, none of
which represent more than three percent (3%) of our total annual sales. We
maintain a diverse customer base with no significant geographical or customer
concentration. Within our core specialty metals business we believe we are
recognized as North America's leading industrial distributor of carbon, alloy
and stainless steels; nickel alloy; aluminum; titanium; copper and brass as well
as an industry pioneer and premier provider of material management programs that
are designed to reduce our customer's total cost.

     Through our subsidiary Total Plastics, Inc. we also distribute a broad
range of value-added industrial plastics. Together Castle and our affiliated
companies operate in over 50 locations throughout North America.

                               RECENT DEVELOPMENTS

During the first quarter of 2002, we announced a voluntary stock option exchange
program, or Offer, for our employees. Under the program, our employees had the
opportunity, if they so chose, to elect to cancel outstanding stock options held
by them in exchange for new options to be granted at a future date at the then
current fair market value. The number of new options granted to an employee who
participates in the Offer will equal one half of the number of outstanding stock
options tendered by such employee. The Offer remained outstanding until 5:00
p.m., on March 22, 2002. A total of 55 individuals elected to participate in the
Offer. These individuals tendered a total of 305,759 options to purchase common
stock in return for our promise to grant new options on the grant date of
September 27, 2002.

                                  RISK FACTORS

     You should carefully consider the risks described below before making a
decision to invest in our common stock. The risks and uncertainties described
below are examples only and are not the only ones that we face. Additional risks
and uncertainties that are not presently known to us or that we do not currently
believe are important to an investor may also harm our business operations. If
any of the events, contingencies, circumstances or conditions described in the
following risks actually occur, our business, financial condition or results of
operations could be seriously harmed. If that occurs, the trading price of our
common stock could decline, and you may lose part or all of your investment.

     Our future operating results depend on a number of factors beyond our
control such as the prices for metals, which could cause our results to be
adversely affected.

     The prices we pay for raw materials and the prices we charge for products
may change depending on many factors not in our control, including general
economic conditions (both domestic and international), competition, production
levels, import duties and other trade restrictions, and currency fluctuations.
To the extent metals prices decline, this generally would mean lower sales and
possibly lower net income, depending on the timing of the price changes. To the
extent we are not able to pass on to our customers any increases in our raw
materials prices, our results of operations may be adversely affected.

     We service industries that are highly cyclical, and any downturn in our
customers' industries could reduce our revenue and profitability which could
result in a negative impact on our stock price.

     Many of our products are sold to industries that experience significant
fluctuations in demand based on economic conditions, energy prices, consumer
demand and other factors beyond our control. As a result of the volatility in
the industries we serve, we may have difficulty increasing or maintaining our
level of sales of profitability if we are not able to divert sales of our
products to customers in other industries when one or more of our customers'
industries experiencing a decline. Therefore, we may not be able to increase or
maintain its level of sales in periods of economic stagnation or downturn.


     The success of our business is affected by general economic conditions,
and, accordingly, our business has been and could continue to be adversely
impacted by an economic slowdown or recession.

     Periods of economic slowdown or recession in the United States, or the
public perception that one may occur, can decrease the demand for our products,
affect the availability and cost of our products and adversely impact our
business. The current general economic slowdown has suppressed activity and
demand in our industry over the past several years. This has been reflected in
our financial losses in 2000 and 2001. Our overall financial results in 2002
will be substantially dependent upon the extent to which conditions in our
industry and the general economy improve during the remainder of the year. A
prolonged slowdown or slower than expected recovery will adversely affect our
business.

     Production time and the cost of our products could increase if we were to
lose one of our primary suppliers, which could adversely affect our ability to
meet our customer demands.

     If, for any reason, our primary suppliers of metals should curtail or
discontinue their delivery of such raw materials to us in the quantities we need
and at prices that are competitive, our business could suffer since we have few
long-term contracts to purchase metals. If, in the future, we are unable to
obtain sufficient amounts of the necessary raw materials at competitive prices
and on a timely basis from our traditional suppliers, we may not be able to
obtain such raw materials from alternative sources at competitive prices to meet
our delivery schedules, which could have an adverse impact on our revenues and
profitability.

     Our industry is highly competitive, which may force us to lower our prices
thus causing an adverse affect on net income.

     The principal markets that we serve are highly competitive. Competition is
based principally on price, service, quality, production capabilities, inventory
availability and timely delivery. We compete in a highly fragmented industry.
Competition in the various markets in which we participate comes from a large
number of value-added metals processors, service centers on a regional and local
basis, some of which have greater financial resources than we do and some of
which have more established brand names in the local markets we serve. We also
compete to a lesser extent with primary metals producers who typically sell to
very large customers requiring shipments of large volumes of metal. Increased
competition could force us to lower our prices or to offer increased services at
a higher costs to us, which could reduce our gross margins and net income.

                                       4




     Ownership of our stock is concentrated, which may limit stockholder ability
to influence corporate matters.

     Affiliates and family members of one of our directors, Michael W. Simpson,
collectively control over approximately 35% of our common stock through various
estates, partnerships, corporations, trusts and individual ownership. This
includes, without limitation, shares owned by Mr. Simpson, and shares controlled
by various trusts for which our director, Patrick J. Herbert, III, acts as
trustee. This concentration of ownership retains the voting power to exercise
significant influence over the outcome of matters requiring a stockholder vote,
including the election of directors and the approval of significant corporate
matters. Such a concentration of control could adversely affect the market price
of our common stock or prevent a change in control.

     Trading volume of our stock is small which increases the volatility of our
stock price, which may have an adverse affect on stockholder's investment.

     Although a public market exists for our common stock, trading activity has
been limited. Due to the relatively small number of shares currently
outstanding, the trading of a relatively small number of shares could subject
the stock price to volatility and significantly affect the market price of our
common stock. The market price of our common stock is affected by a number of
other factors, including variations in our operating results, evolving business
prospects and competitors, as well as general conditions in the economy and the
financial markets. Also, the equity markets generally have experienced
significant price and volume fluctuations in recent years.

     We have various mechanisms in place that may prevent a change in control
that stockholders may otherwise consider favorable.

     In addition to the high concentration of inside ownership described above,
our certificate of incorporation and by-laws and the Maryland General
Corporation Law include provisions that may be deemed to have antitakeover
effects and may delay, defer or prevent a takeover attempt that stockholders
might consider in their best interests. Our certificate of incorporation
contains provisions that require the approval of two-thirds of the stockholders
entitled to vote to amend our certificate of incorporation (unless our Board of
Directors has unanimously approved the amendment). In addition, our by-laws may
be amended only by our board of directors, and they contain certain advance
notice procedures for nominating candidates for election to the board of
directors. Our board of directors is empowered to issue up to 10,000,000 shares
of preferred stock and to determine the price, rights, preferences and
privileges of such shares, without any further stockholder action. The existence
of this "blank-check" preferred stock could make more difficult or discourage an
attempt to obtain control of the Company by means of a tender offer, merger,
proxy contest or otherwise. In addition, this "blank check" preferred stock, and
an issuance thereof, may have an adverse effect on the market price of our
common stock. Furthermore, we are subject to the antitakeover provisions of the
Maryland General Corporation Law that prohibit us from engaging in a "business
combination" with an "interested stockholder" for a period of five years after
the date of the transaction in which the person first becomes an "interested
stockholder," unless the business combination or stockholder interest is
approved in a prescribed manner. The application of these and certain other
provisions of the certificate of incorporation could also have the effect of
delaying or preventing a change of control of the Company, which could adversely
affect the market price of our common stock.

                                 USE OF PROCEEDS

     We will not receive any of the proceeds from the sale of shares of common

Employees Pension Plan (the "Salaried Plan") and the A. M. Castle & Co. Hourly
Employees Retirement Plan (the "Hourly Plan" and collectively with the Salaried

contribute up to 335,000 additional newly issued shares to the Trust, allocated
between the Salaried Plan and the Hourly Plan in a manner approximately
consistent with each Plan's current relative share ownership. This will result
in the Trust owning up to an aggregate of approximately 1,020,190 shares of
common stock, representing approximately 6.9% of our outstanding common stock.

                     PLAN OF DISTRIBUTION AND OFFERING PRICE

      The Selling Stockholder is offering for resale under this prospectus an
aggregate of up to 1,020,190 shares of our common stock. The Selling
Stockholder, or its assignees and successors-in-interest may sell, from time to
time, any or all of the shares of common stock covered by this prospectus on any
stock exchange, market or trading facility on which the shares are traded or in
private transactions. These sales may be at fixed or negotiated prices. The
Selling Stockholder may use any one or more of the following methods when
selling shares:

   o  Sales on the Chicago Stock Exchange or the American Stock Exchange, in the
      over-the-counter market or otherwise at prices and at terms then
      prevailing or at prices related to the then current market price;

   o  Underwritten offerings;

   o  Ordinary brokerage transactions and transactions in which the
      broker-dealer solicits purchasers;

   o  Block trades in which the broker-dealer will attempt to sell the shares as
      agent but may position and resell a portion of the block as principal to
      facilitate the transaction;

   o  Purchases by a broker-dealer as principal and resale by the broker-dealer
      for its account;

   o  An exchange distribution in accordance with the rules of the applicable
      exchange;

   o  Privately negotiated transactions;

   o  Short sales;

   o  Broker-dealers may agree with the Selling Stockholder to sell a specified
      number of such shares at a stipulated price per share;

   o  A combination of any such methods of sale; or

   o  Any other method permitted pursuant to applicable law.

      The Selling Stockholder may also sell shares under Rule 144 as promulgated
under the Securities Act of 1933, if available, rather than under this
prospectus.

      The Selling Stockholder may, together with any agent of the Selling
Stockholder, accept or reject in whole or in part any proposed purchase of the
shares of common stock offered by this prospectus. We will not receive any
proceeds from the offering of shares by the Selling Stockholder.

      Under applicable rules and regulations under the Securities Exchange Act
of 1934, any person engaged in a distribution of the shares of common stock
covered by this prospectus may be limited in its ability to engage in market
activities with respect to such shares. The Selling Stockholder, for example,
will be subject to applicable provisions of the Securities Exchange Act of 1934

                                       6




and the rules and regulations under it, including, without limitation,
Regulation M, which provisions may restrict activities of the Selling
Stockholder and limit the timing of purchases and sales of any shares of common
stock by the Selling Stockholder. Furthermore, under Regulation M, persons
engaged in a distribution of securities are prohibited from simultaneously
engaging in market making and other activities with respect to such securities
for a specified period of time prior to the commencement of such distributions,
subject to specified exceptions or exemptions. The foregoing may affect the
marketability of the shares offered by this prospectus.

     The Selling Stockholder may also engage in short sales against the box
(where the seller actually owns the stock, but does not want to close out the
position, but instead sells a put option covered by the retained position), puts
(an option giving the holder of the option the right to sell the stock at a
given price by a given date) and calls (the opposite of a put, a call is an
option that gives the holder the right to buy stock at a given price in a given
period of time) and other transactions in our securities or derivatives of our
securities and may sell or deliver shares in connection with these trades. The
Selling Stockholder may pledge its shares to brokers under the margin provisions
of customer agreements or other lenders under the terms of the loan agreements.
If the Selling Stockholder defaults on a margin loan or other loan, the broker
or lender may offer and sell, from time to time, the pledged shares.

     The Selling Stockholder may sell shares directly to market makers acting as
principals and/or broker-dealers acting as agents for themselves or their
customers. Broker-dealers engaged by the Selling Stockholder may arrange for
other broker-dealers to participate in sales. Broker-dealers may receive
commissions, concessions or discounts from the Selling Stockholders (or, if any
broker-dealer acts as agent for the purchaser of shares, from the purchaser) in
amounts to be negotiated. The Selling Stockholder does not expect these
commissions and discounts to exceed what is customary in the types of
transactions involved. Market makers and block purchasers that purchase the
shares will do so for their own account and at their own risk. It is possible
that the Selling Stockholder will attempt to sell shares in block transactions
to market makers or other purchasers at a price per share that may be below the
then-current market price. We cannot make assurances that all or any of the
shares of common stock will be sold by the Selling Stockholders.

     The Selling Stockholder and any broker-dealers or agents that are involved
in selling the shares may be deemed to be underwriters within the meaning of the
Securities Act of 1933 in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act of 1933.

     We have not registered or qualified the shares of common stock offered by
this prospectus under the laws of any country, state or jurisdiction, other than
the United States.

     We are paying all fees and expenses incident to the registration of the
shares. The Selling Stockholders will pay any sales commissions or other
seller's compensation applicable to these transactions.

     Our common stock is currently traded on the Chicago Stock Exchange and the
American Stock Exchange. The public offering price for any shares that are sold
will be determined by the price indicated on such system at the time such sale
occurs, or at such price as shall be determined through private negotiations
between the buyers and the Selling Stockholder, or its agents.

Item 14.  Other Expenses of Issuance and Distribution.

      The following table sets forth the costs and expenses payable by us in
connection with the sale of our common stock being registered hereby. All the
amounts shown are estimated, except the Securities Exchange Commission
registration fee.

         SEC registration fee..................................$936
         Printing expenses......................................-0-
         Legal fees and expenses.............................12,000
         Accounting fees and expenses.........................3,275
         Miscellaneous expenses...............................8,789

                            Total..................................      $25,000


Item 15.  Indemnification of Directors and Officers.

      We are a Maryland corporation, subject to the applicable indemnification
provisions of the General Corporation Law of the State of Maryland (the "MGCL").
Section 2-418 of the MGCL empowers a Maryland corporation to indemnify, subject
to certain prescribed standards, any person in connection with any action, suit
or proceeding brought or threatened because such person is or was a director,
officer, employee or agent of the corporation or was serving as such with
respect to another corporation or other entity at the request of such
corporation.

      Section 2-405.2 of the MGCL permits a Maryland corporation to include in
its certificate of incorporation a provision eliminating or limiting a
director's liability to a corporation or its stockholders for money damages. A
Maryland corporation may indemnify its present and former directors and
officers, among others, against (1) judgments, (2) penalties, (3) fines, (4)
settlements and (5) reasonable expenses actually incurred by them in connection
with any proceeding to which they may be made a party by reason of their service
in those or other capacities.

          The MGCL does not permit a corporation to indemnify its present and
former directors, officers, agents or employees if it is established that:

   o  the act or omission of the director, officer, employee or agent was
      material to the matter giving rise to the proceeding and was committed in
      bad faith or was the result of active and deliberate dishonesty;

   o  the director, officer, employee or agent actually received an improper
      personal benefit in money, property or services; or

   o  in the case of any criminal proceeding, the director, officer, employee or
      agent had reasonable cause to believe that the act or omission was
      unlawful.

          Unless a corporation's charter provides otherwise, which our charter
does not, the MGCL requires a corporation to indemnify a director or officer who
has been successful, on the merits or otherwise, in the defense of any
proceeding to which he is made a party by reason of his service in that
capacity.




     Under the MGCL, a Maryland corporation generally may not indemnify a person
for an adverse judgment in a suit by or in the right of the corporation. Also, a
Maryland corporation generally may not indemnify a person for a judgment of
liability on the basis that personal benefit was improperly received. In either
of these cases, a Maryland corporation may indemnify a person for expenses only
if a court so orders. Our bylaws obligate us to indemnify our directors and
officers, whether serving us or, at our request, any other entity, to the
maximum extent required or permitted by the MGCL, including the advancement of
expenses under the procedures and to the maximum extent permitted by law.

     Our charter also contains provisions that eliminate and limit the personal
liability of directors to the full extent permitted by the MGCL. Pursuant to the
MGCL, our charter also limits the personal liability of officers to the same
extent as directors. Under the MGCL, limitation of personal liability of
directors or officers is permitted in all but the following two situations: (1)
for the amount of any improper benefit they actually receive or (2) to the
extent that a judgment or final adjudication adverse to the director or officer
in a proceeding based on the finding in that proceeding that the person's
action, or failure to act, was the result of active and deliberate dishonesty
and was material to the cause of action adjudicated in the proceeding.

     We may maintain insurance, at our expense, to protect us and any of our
directors, officers, employees or agents or another corporation, partnership,
joint venture, trust or other enterprise against any expense, liability or loss,
whether or not we would have the power to indemnify such person against expense,
liability or loss under the MGCL.

Item 16.  Exhibits.

     (a) Exhibits (all filed herewith except where otherwise noted):

          5.1  Opinion of Jerry M. Aufox regarding the legality of the
               securities being registered (previously filed)

               pursuant to Rule 437a under the Securities Act)

          23.2 Consent of Jerry M. Aufox (included in Exhibit 5.1)

          24   Powers of Attorney (previously filed)


Item 17.  Undertakings.

     (a) The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

               (i) To include any prospectus required by section 10(a)(3) of the
          Securities Act of 1933;

               (ii) To reflect in the prospectus any facts or events arising
          after the effective date of the registration statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Securities and Exchange Commission pursuant
          to Rule 424(b) under the Securities Act of 1933, as amended, if, in
          the aggregate, the changes in volume and price represent no more than
          a 20% change in the maximum aggregate offering price set forth in the
          "Calculation of Registration Fee" table in the registration statement;




               (iii) To include any material information with respect to the
          plan of distribution not previously disclosed in the registration
          statement or any material change to such information in the
          registration statement;

               Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
          not apply if the information required to be included in a
          post-effective amendment by those paragraphs is contained in periodic
          reports filed with or furnished to the Commission by the Registrant
          pursuant to Section 13 or Section 15(d) of the Securities Exchange Act
          of 1934 that are incorporated by reference in the registration
          statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934, as amended, that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933, as amended, and is, therefore, unenforceable. In
the event that a claim for the indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.





                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Amendment
No. 2 to Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Franklin Park, State of Illinois, on
September 12, 2002.
