Exhibit 10.23

                             EMPLOYMENT AGREEMENT

     THIS AGREEMENT, by and between Ryerson Tull, Inc. (the "Company") and Gary
J. Niederpruem (the "Executive") effective as of September 1, 1999 (the
"Effective Date");

                               WITNESSETH THAT:

     WHEREAS, the Company has appointed Executive to the position of Executive
Vice President, and Executive has accepted such appointment; and

     WHEREAS, in connection with such appointment, the Company and Executive
desire to enter into this Agreement;

     NOW, THEREFORE, in consideration of the Executive's appointment as
Executive Vice President, and for other good and valuable consideration the
receipt of which is hereby acknowledged, it is agreed by the Executive and
Company as follows:

     1.  Duties.  The Executive agrees that while he is employed by the Company,
he will devote his full business time, energies and talents to serving as the
Executive Vice President of the Company and providing services for the Company
at the direction of the Chairman of the Company. The Executive shall have such
duties and responsibilities as may be assigned to him from time to time by the
Chairman, shall perform all duties assigned to him faithfully and efficiently,
subject to the direction of the Chairman, and shall have such authorities and
powers as are inherent to the undertakings applicable to his position and
necessary to carry out the responsibilities and duties required of him
hereunder; provided, however, that the Executive shall not be required to
perform any duties while he is disabled. Notwithstanding the foregoing or any
other provisions of this Agreement, the Executive and the Company understand and
agree that the responsibilities and duties of the Executive, in his capacity as
Executive Vice President of the Company, may change from time to time due to
other changes in the nature and structure of the Company's business and that any
such changes in the Executive's duties and responsibilities that are consistent
with such changes in the Company's business shall not constitute a reduction in
the Executive's duties and responsibilities for purposes of this Agreement.


     2.  Compensation.  Subject to the terms and conditions of this Agreement,
during the Employment Period while the Executive is employed by the Company, the
Company shall compensate him for his services as follows:

     (A)  The Executive shall receive, for each twelve-consecutive month period
          beginning on March 8, 1999, and each anniversary thereof, an annual
          salary of $285,700 (the "Salary"), which Salary shall be payable in
          substantially equal bi-weekly installments. The Executive's rate of
          Salary shall be reviewed annually beginning in February, 2000.

     (B)  The Executive shall be entitled to receive bonuses from the Company in
          accordance with the bonus plans of the Company as in effect from time
          to time. As Executive Vice President his target bonus award percentage
          shall be 50% of the midpoint of his grade, subject to annual approval
          of the Compensation Committee of the Board of Directors.

     (C)  Except as otherwise specifically provided to the contrary in this
          Agreement, the Executive shall be provided with health, welfare and
          other fringe benefits to the same extent and on the same terms as
          those benefits are provided by the Company from time to time to the
          Company's other senior management executives.

     (D)  The Executive shall be reimbursed by the Company, on terms and
          conditions that are substantially similar to those that apply to other
          similarly situated senior management executives of the Company, for
          reasonable out-of-pocket expenses for entertainment, travel, meals,
          lodging and similar items which are consistent with the Company's
          expense reimbursement policy and actually incurred by the Executive in
          the promotion of the Company's business.

     (E)  The Company shall pay or shall reimburse the Executive for his monthly
          country club dues and assessments; provided, however, that such
          payment or reimbursement, as applicable, shall apply only to the club
          at which the Executive was a member immediately prior to the date
          hereof unless it is necessary for the Executive to change clubs and,
          in any event shall apply to only one club at any given point in time.

     (F)  The Company shall pay the Executive for the amount of the monthly
          lease payment for the automobile that the Executive uses for business;
          provided,

                                      -2-


          however, that the Company shall report as income to the Executive any
          amounts required by law or the policies of the Company relating to the
          Executive's personal use of such automobile.

     (G)  The Executive shall be recommended for stock awards in the same manner
          as may be in effect from time to time for other similarly situated
          executive vice presidents.

     3.   Rights and Payments Upon Termination. The Executive's right to
benefits and payments, if any, for periods after the date on which his
employment with the Company terminates for any reason (his "Termination Date")
shall be determined in accordance with this Section 3:

     (A)  Termination by the Company for Reasons Other Than Cause; Termination
          by the Executive for Good Reason. If the Executive's termination by
          the Company occurs for any reason other than Cause or is a result of
          the Executive's termination of employment for Good Reason (and is not
          on account of the Executive's death, disability, or voluntary
          resignation, the mutual agreement of the parties or any other reason),
          then the Executive shall receive from the Company for the period
          commencing on his Termination Date and ending on the earliest of (i)
          the twenty-fourth month after the Executive's Termination Date; (ii)
          the date on which the Executive violates the provisions of Sections 4,
          5 or 6 of this Agreement; or (iii) the date of the Executive's death,
          the Salary, bonus and benefits in effect as of his Termination Date,
          payable in accordance with the provisions of Paragraph 3(B). The
          biweekly salary amounts will continue as described above. Benefits
          that will continue will include medical, dental, basic life insurance,
          any optional life insurance and any optional accidental death and
          dismemberment insurance. Bonus shall mean two payments of the average
          annual amount of the award paid to the Executive pursuant to the
          annual incentive plan or successor plan with respect to the three
          years immediately preceding that in which the Termination Date occurs.

          Base salary payments to the Executive during the aforementioned
          twenty-four month period shall not preclude the Executive's
          eligibility for payments under the Company's severance plan.

          Twenty-four months of additional age and service credit will be
          provided to the Executive's RT Pension and the RT Supplemental Plan
          using the methodology

                                      -3-


          described in the Executive's Change in Control Agreement except that
          any lump sum payment will be made twenty-four months after the
          Executive's Termination Date and only if the Executive has not
          violated the Confidentiality, Nonsolicitation and Noncompetition
          provisions of this Agreement.

     (B)  Termination By Company for Cause. If the Executive's termination is a
          result of the Company's termination of the Executive's employment on
          account of Cause, then, except as agreed in writing between the
          Executive and the Company, the Executive shall have no right to future
          payments or benefits under this Agreement (and the Company shall have
          no obligation to make any such future payments or provide any such
          future benefits) for periods after the Executive's Termination Date.

     (C)  Termination for Death or Disability. If the Executive's termination is
          caused by the Executive's death or permanent disability, then the
          Executive (or in the event of his death, his estate) shall be entitled
          to continuing payments of his Salary for the period commencing on his
          Termination Date and ending on the earlier of (i) the last day of the
          calendar month in which his Termination Date occurs or (ii) the date
          on which the Executive violates the provisions of Sections 4, 5 or 6
          of this Agreement.

     (D)  Termination for Voluntary Resignation, Mutual Agreement or Other
          Reasons. If the Executive's termination occurs on account of his
          voluntary resignation, mutual agreement of the parties, or any reason
          other than those specified in Paragraphs (A), (B) or (C) above then,
          except as agreed in writing between the Executive and the Company, the
          Executive shall have no right to future payments or benefits under
          this Agreement (and the Company shall have no obligation to make any
          such future payments or provide any such future benefits) for periods
          after the Executive's Termination Date. The Executive's termination of
          employment for Good Reason shall not be treated as a voluntary
          resignation for purposes of this Agreement.

     (E)  Definitions. For purposes of this Agreement:

          (i)  The term "Cause" shall mean:

               (a)  the continuous performance of his duties (under this
                    Agreement) in a manner that is inconsistent with past,
                    acceptable

                                      -4-



                    performance over a normal business cycle; or in a
                    way that has a demonstrable negative impact on the results
                    of the Company as determined by the Chairman and CEO of the
                    Company.  The Chairman and CEO must provide a notice of
                    unsatisfactory performance and a reasonable corrective
                    action period; or

               (b)  the willful engaging by the Executive in conduct which is
                    demonstrably and materially injurious to the Company or its
                    affiliates, monetarily or otherwise, as determined by the
                    Chairman and CEO; or

               (c)  conduct by the Executive that involves theft, fraud or
                    dishonesty; or

               (d)  the Executive's violation of the provisions of Sections 1, 2
                    or 3 hereof.

          (ii) The term "Good Reason" means (a) the assignment to the Executive
               duties which are materially inconsistent with his duties as
               Executive Vice President of the Company, including, without
               limitation, a material diminution or reduction in his title,
               office or responsibilities or a reduction in his rate of Salary,
               or (b) the relocation of the Executive to a location that is not
               within the greater Chicago metropolitan area.

     Notwithstanding any other provision of this Agreement, the Executive shall
     automatically cease to be an employee of the Company and its affiliates as
     of his Termination Date and, to the extent permitted by applicable law, any
     and all monies that the Executive owes to the Company shall be repaid
     before any post-termination payments are made pursuant to the Executive
     pursuant to this Agreement.

     4.   Confidential Information. The Executive agrees that:

     (A)  Except as may be required by the lawful order of a court or agency of
          competent jurisdiction, or except to the extent that the Executive has
          express authorization from the Company, he shall keep secret and
          confidential indefinitely all non-public information (including,
          without limitation, information regarding litigation and pending
          litigation) concerning the Company and its affiliates which was
          acquired by or disclosed to the Executive during the course of his

                                      -5-



          employment with the Company,  and not to disclose the same, either
          directly or indirectly, to any other person, firm, or business entity,
          or to use it in any way.

     (B)  Upon his Termination Date or at the Company's earlier request, he will
          promptly return to the Company any and all records, documents,
          physical property, information, computer disks or other materials
          relating to the business of the Company and its affiliates obtained by
          him during his course of employment with the Company.

     (C)  The Executive shall keep the Company informed of, and shall execute
          such assignments as may be necessary to transfer to the Company or its
          affiliates the benefits of, any inventions, discoveries, improvements,
          trade secrets, developments, processes, and procedures made by the
          Executive, in whole or in part, or conceived by the Executive either
          alone or with others, which result from any work which the Executive
          may do for or at the request of the Company, whether or not conceived
          by the Executive while on holiday, on vacation, or off the premises of
          the Company, including such of the foregoing items conceived during
          the course of employment which are developed or perfected after the
          Executive's termination of employment. The Executive shall assist the
          Company or other nominated by it, to obtain patents, trademarks and
          service marks and the Executive agrees to execute all documents and to
          take all other actions which are necessary or appropriate to secure to
          the Company and its affiliates the benefits thereof. Such patents,
          trademarks and service marks shall become the property of the Company
          and its affiliates. The Executive shall deliver to the Company all
          sketches, drawings, models, figures, plans, outlines, descriptions or
          other information with respect thereto.

     (D)  To the extent that any court or agency seeks to have the Executive
          disclose confidential information, he shall promptly inform the
          Company, and he shall take such reasonable steps to prevent disclosure
          of Confidential Information until the Company has been informed of
          such requested disclosure. To the extent that the Executive obtains
          information on behalf of the Company or any of its affiliates that may
          be subject to attorney-client privilege as to the Company's attorneys,
          the Executive shall take reasonable steps to maintain the
          confidentiality of such information and to preserve such privilege.

     (E)  Nothing in the foregoing provisions of this Section 4 shall be
          construed so as to prevent the Executive from using, in connection
          with his employment for

                                      -6-



          himself or an employer other than the Company or any of its
          affiliates, knowledge which was acquired by him during the course of
          his employment with the Company and its affiliates, and which is
          generally known to persons of his experience in other companies in the
          same industry.

     5.   Nonsolicitation.  While the Executive is employed by the Company and
its affiliates and for a period of  two years after the date the Executive
terminates employment with the Company and its affiliates for any reason, the
Executive covenants and agrees that he will not, whether for himself or for any
other person, business, partnership, association, firm, company or corporation,
directly or indirectly, call upon, solicit, divert or take away or attempt to
solicit, divert or take away, any of the customers or employees of the Company
or its affiliates in existence from time to time during his employment with the
Company and its affiliates.

     6.   Noncompetition.  While the Executive is employed by the Company and
its affiliates, and for a period of  two years after the date the Executive
terminates employment with the Company and its affiliates, the Executive
covenants and agrees that he will not, directly or indirectly, engage in,
assist, perform services for, plan for, establish or open, or have any financial
interest (other than (i) ownership of 1% or less of the outstanding stock of any
corporation listed on the New York or American Stock Exchange or included in the
National Association of Securities Dealers Automated Quotation System or (ii)
ownership of securities in any entity affiliated with the Company) in any
person, firm, corporation, or business entity (whether as an employee, officer,
director or consultant) that engages in an activity in any state in which the
Company or its affiliates is conducting or has reasonable expectations of
commencing business activities at the date of the Executive's termination of
employment, which is the same as, similar to, or competitive with the metals
service center, processing and distribution business of the Company and its
affiliates.

     7.   Equitable Remedies.  The Executive acknowledges that the Company would
be irreparably injured by a violation of Sections 4, 5 and 6 and agrees that the
Company, in addition to other remedies available to it for such breach or
threatened breach, shall be entitled to a preliminary injunction, temporary
restraining order, other equivalent relief, restraining the Executive from any
actual or threatened breach of Sections 4, 5 and 6 without any bond or other
security being required.

     8.   Defense of Claims.  The Executive agrees that, during his employment
with the Company and after his termination, he will cooperate with the Company
and its affiliates in the defense of any claims that may be made against the
Company or its affiliates to the extent that

                                     -7-


such claims may relate to services performed by him for the Company. To the
extent travel is required to comply with the requirements of this Section 8, the
Company, shall to the extent possible, provide the Executive with notice at
least 10 days prior to the date on which such travel would be required and the
Company agrees to reimburse the Executive for all of his reasonable actual
expenses associated with such travel; provided, however, that if the Company
reasonably expects the travel to be extensive or unduly burdensome to the
Executive from a financial perspective, the Company may provide to the Executive
pre-paid tickets for transportation in connection with such travel.

     9.   Notices.  Notices provided for in this Agreement shall be in writing
and shall be deemed to have been duly received when delivered in person or sent

in accordance herewith, except that a notice of change of address shall be
effective only upon actual receipt.

     10.  Withholding.  All compensation payable under this Agreement shall be
subject to customary withholding taxes and other employment taxes as required
with respect to compensation paid by a corporation to an employee and the amount
of compensation payable hereunder shall be reduced appropriately to reflect the
amount of any required withholding. The Company shall have no obligation to make
any payments to the Executive or to make the Executive whole for the amount of
any required taxes.

     11.  Successors.  This Agreement shall be binding on, and inure to the
benefit of, the Company and its successors and assigns and any person acquiring,

     12.  Nonalienation.  The interests of the Executive under this Agreement
are not subject to the claims of his creditors, other than the Company, and may
not otherwise be voluntarily or involuntarily assigned, alienated or encumbered.

     13.  Waiver of Breach.  The waiver by either the Company or the
Executive of a breach of any provision of this Agreement shall not operate as or
be deemed a waiver of any subsequent breach by either the Company or the
Executive.  Continuation of payments hereunder by the Company following a breach
by the Executive of any provision of this Agreement shall not preclude the
Company from thereafter terminating said payments based upon the same violation.

     14.  Severability.  It is mutually agreed and understood by the parties
that should any of the agreements and covenants contained herein be determined
by any court of competent jurisdiction to be invalid by virtue of being vague or
unreasonable, including but not limited to the provisions of Sections 4, 5 and
6, then the parties hereto consent that this Agreement shall be amended
retroactive to the date of its execution to include the terms and conditions
said court deems to be reasonable and in conformity with the original intent of
the parties and the parties hereto consent that under such circumstances, said
court shall have the power and authority to determine what is reasonable and in
conformity with the original intent of the parties to the extent that said
covenants and/or agreements are enforceable.

     15.  Applicable Law.  This Agreement shall be construed in accordance with
the laws of the State of Illinois.

     16.  Amendment.  This Agreement may be amended or cancelled by mutual
Agreement of the parties in writing without the consent of any other person.

     17.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be an original,
but all such counterparts shall together constitute one and the same instrument.
Each counterpart may consist of a copy hereof containing multiple signature
pages, each signed by one party hereto, but together signed by both of the
parties hereto.

     18.  Other Agreements.  This Agreement constitutes the sole and complete
Agreement between the Company and the Executive and supersedes all other
agreements, both oral and written, between the Company and the Executive with
respect to the matters contained herein including, without limitation any
severance agreements or arrangements between the parties; provided, however,
that this Agreement does not supersede the Change in Control

                                      -9-


Agreement. No verbal or other statements, inducements, or representations have
been made to or relied upon by the Executive. The parties have read and
