THE BANK OF NEW YORK TRUST COMPANY, N.A.

as Trustee, certifies

that this is one of

the Securities referred

to in the Indenture.

RYERSON TULL, INC.

8¼% Senior Note, Series A, due 2011

Ryerson Tull, Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above.

The Company will pay interest semi-annually on June 15 and December 15, commencing on June 15, 2005. Interest on the Securities will accrue from the most recent date to which interest has been paid on the Securities or, if no interest has been paid, from December 13, 2004. The Company shall pay interest on overdue principal, and on overdue premium, if any (plus interest on such interest to the extent lawful), at the rate borne by the Securities to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

If an exchange offer (the “Exchange Offer”) registered under the Securities Act is not consummated or a shelf registration statement (the “Shelf Registration Statement”) under the Securities Act with respect to resales of the Securities is not declared effective by the SEC on or before the date that is 210 days after the Issue Date (the “Target Registration Date”) in accordance with the terms of the Registration Rights Agreement dated December 13, 2004 among the Company, the Subsidiary Guarantor and the Initial Purchasers, the annual interest rate borne by the Securities shall be increased from the rate shown above by (i) 0.50% per annum for the first 90-day period immediately following the Target Registration Date and (ii) an additional 0.50% per annum with respect to each subsequent 90-day period, in each case until the Exchange Offer is completed or the Shelf Registration Statement, if required, is declared effective by the SEC or the Securities become freely tradable under the Securities Act, up to a maximum of 1.00% per annum of additional interest. If the Company receives a request (a “Shelf Request”) from an Initial Purchaser requesting that a Shelf Registration Statement be filed due to an unsold allotment of Securities held by such Initial Purchaser, and the Shelf Registration Statement is not declared effective by the SEC by the later of (x) 180 days after the Issue Date and (y) 90 days after the delivery of such Shelf Request (the “Shelf Additional Interest Date”), the annual interest rate borne by the Securities shall be increased from the rate shown above by (i) 0.50% per annum for the first 90-day period immediately following the Shelf Additional Interest Date and (ii) an additional 0.50% per annum with respect to each subsequent 90-day period, in each case until the Shelf Registration Statement is declared effective, up to a maximum of 1.00% per annum of additional interest. The Holder of this Security is entitled to the benefits of such Registration Rights Agreement.

By no later than 10:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Security is due and payable, the Company shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal,

premium, if any, and/or interest. The Company will pay interest (except Defaulted Interest) to the Persons who are registered Holders of Securities at the close of business on the June 1 or December 1 next preceding the interest payment date even if Securities are cancelled, repurchased or redeemed after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal, premium, if any, and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Securities represented by a Global Security (including principal, premium, if any, and interest) will be made by the transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depository. The Company will make all payments in respect of a Definitive Security (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

Initially, The Bank of New York Trust Company, N.A. (the ^“Trustee”) will act as Trustee, Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice to any Securityholder. Any of the domestically organized Wholly-Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

The Company issued the Securities under an Indenture dated as of December 13, 2004 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Company, the Subsidiary Guarantor and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and Securityholders are referred to the Indenture and the Act for a statement of those terms.

The Securities are general unsecured, senior obligations of the Company. The aggregate principal amount of securities that may be authenticated and delivered under the Indenture is unlimited. This Security is one of the 8¼% Senior Notes, Series A, due 2011 referred to in the Indenture. The Securities include (i) $150,000,000 aggregate principal amount of the Company’s 8¼% Senior Notes, Series A, due 2011 issued under the Indenture on December 13, 2004 (herein called “Initial Securities”), (ii) if and when issued, additional 8¼% Senior Notes, Series A, due 2011 or 8¼% Senior Notes, Series B, due 2011 of the Company that may be issued from time to time under the Indenture subsequent to December 13, 2004 (herein called “Additional Securities”) and (iii) if and when issued, the Company’s 8¼% Senior Notes,

Series B, due 2011 that may be issued from time to time under the Indenture in exchange for Initial Securities or Additional Securities in an offer registered under the Securities Act as provided in the Registration Rights Agreement (herein called “Exchange Securities”). The Initial Securities, Additional Securities and Exchange Securities are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the incurrence of indebtedness, the making of restricted payments, the sale of assets and subsidiary stock, the incurrence of certain liens, sale-leaseback transactions, affiliate transactions, the sale of capital stock of restricted subsidiaries, the making of payments for consents, the entering into of agreements that restrict distributions from restricted subsidiaries and the consummation of mergers and consolidations. The Indenture also imposes requirements with respect to the provision of financial information and the provision of guarantees of the Securities by certain subsidiaries.

To guarantee the due and punctual payment of the principal, premium, if any, and interest (including post-filing or post-petition interest) on the Securities and all other amounts payable by the Company under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Subsidiary Guarantors have fully, unconditionally and irrevocably Guaranteed (and future guarantors, together with the Subsidiary Guarantors on the Issue Date, will fully, unconditionally and irrevocably Guarantee), jointly and severally, to each Holder of the Securities and the Trustee the Guarantor Obligations pursuant to Article X of the Indenture on a senior basis.

Except as set forth below, the Securities will not be redeemable at the option of the Company prior to December 15, 2008. On and after such date, the Securities will be redeemable, at the Company’s option, in whole or in part, from time to time, at any time upon not less than 30 nor more than 60 days’ prior notice mailed by first class mail to each Holder’s registered address, at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest, if any, to the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on December 15 of the years set forth below:

In addition, at any time and from time to time prior to December 15, 2007, the Company may redeem in the aggregate up to 35% of the original principal amount of the Securities (after giving effect to any future issuance of Additional Securities) with the Net Cash Proceeds of one or more Equity Offerings at a redemption price (expressed as a percentage of principal amount) of 108.25%, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the

relevant interest payment date); provided, however, that at least 65% of the original principal amount of the Securities (after giving effect to issuances of Additional Securities) must remain outstanding after each such redemption; provided further, that each such redemption occurs within 60 days of the date of closing of such Equity Offering.

If the optional redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the Person in whose name the Security is registered at the close of business on such record date, and no additional interest will be payable to Holders whose Securities will be subject to redemption by the Company.

In the case of any partial redemption, selection of the Securities for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed or, if the Securities are not listed, then on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate, although no Securities of $1,000 in original principal amount or less will be redeemed in part. Any such notice to the Trustee may be cancelled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect. If any Security is to be redeemed in part only, the notice of redemption relating to such Security shall state the portion of the principal amount thereof to be redeemed. A new Security in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Security. On and after the redemption date, interest will cease to accrue on Securities or portions thereof called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to the Indenture.

If a Change of Control occurs, unless the Company has exercised its right to redeem all of the Securities as described under paragraph 5 of the Securities, then such Change of Control shall constitute a triggering event which shall trigger the obligation of the Company to offer to repurchase from each Holder all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

The Securities are in registered form without coupons in denominations of principal amount of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange (i) any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) for a period beginning 15 days before the mailing of a notice of Securities to be redeemed and ending on the

date of such mailing or (ii) any Securities for a period beginning 15 days before an interest payment date and ending on such interest payment date.

The registered Holder of this Security may be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company for payment as general creditors unless an abandoned property law designates another person and not to the Trustee for payment.

Subject to certain exceptions and conditions set forth in the Indenture, the Company at any time may terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Securities to redemption or maturity, as the case may be.

Subject to certain exceptions set forth in the Indenture, (i) the Indenture and the Securities may be amended or supplemented by the Company, the Subsidiary Guarantors and the Trustee with the written consent of the Holders of at least a majority in principal amount of the then outstanding Securities and (ii) any default (other than with respect to nonpayment or in respect of a provision that cannot be amended without the written consent of each Securityholder affected) or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount of the then outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, to provide for uncertificated Securities in addition to or in place of certificated Securities, to comply with Article IV or Section 10.2 in respect of the assumption by a Successor Company of an obligation of the Company or the assumption by a successor Person of the obligations of any Subsidiary Guarantor under this Indenture, to add Guarantees with respect to the Securities or release a Subsidiary Guarantor in accordance with the Indenture, to secure the Securities, to make any change that would provide any additional rights or benefits to the Holders of the Securities or surrender any right or power conferred upon the Company or that does not adversely affect the rights under the Indenture of any such Holder, to comply with any requirement of the SEC in order to effect or maintain the qualification of this Indenture under the TIA, to provide for the issuance of the Exchange Securities or to provide for the appointment of a successor Trustee.

Under the Indenture, Events of Default include (each of which are more specifically described in the Indenture) (i) default for 30 days in payment of interest or additional interest (as required by the Registration Rights Agreement) when due on the Securities; (ii) default in payment of principal of or premium, if any, on the Securities at Stated Maturity, upon required repurchase or upon optional redemption pursuant to paragraph 5 of the Securities, upon acceleration or otherwise; (iii) the failure by the Company or any Subsidiary Guarantor to comply with its obligations under Article IV or Section 10.2(b) of the Indenture; (iv) failure by the Company to comply for 30 days after notice with any of its obligations under the covenants described under Sections 3.3 through 3.13 inclusive, Section 3.17 and Section 3.20 of the Indenture (in each case, other than a failure to purchase Securities when required under the Indenture, which failure shall constitute an Event of Default under clause (ii) above); (v) the failure by the Company to comply for 60 days after notice with its other agreements contained in the Indenture; (vi) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the Company or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists, or is created after the date of the Indenture, which default (a) is caused by a failure to pay when due principal of or interest or premium, if any, on such Indebtedness within the grace period provided in such Indebtedness (“payment default”) or (b) results in the acceleration of such Indebtedness prior to its final Stated Maturity (the “cross acceleration provision”) and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a payment default or the maturity of which has been so accelerated, aggregates $15.0 million or more; (vii) certain events of bankruptcy, insolvency or reorganization of the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary (the “bankruptcy provisions”); (viii) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $15.0 million (net of any amounts that a reputable and creditworthy insurance company has acknowledged liability for in writing), which judgments are not paid, discharged or stayed for a period of 60 days (the “judgment default provision”); or (ix) any Subsidiary Guarantee of a Significant Subsidiary or group of Restricted Subsidiaries that taken together as of the latest audited financial statements for the Company and its Restricted Subsidiaries would constitute a Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms of the Indenture) or is declared null and void in a judicial proceeding or any Subsidiary Guarantor that is a Significant Subsidiary or a group of Subsidiary Guarantors that taken together as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries would constitute a Significant Subsidiary denies or disaffirms its obligations under the Indenture or its Subsidiary Guarantee. However, a default under clauses (iv) and (v) will not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of the outstanding Securities notify the Company of the default and the Company does not cure such default within the time specified in clauses (iv) and (v) hereof after receipt of such notice.

If an Event of Default (other than an Event of Default described in (vii) hereof) occurs and is continuing, the Trustee by notice to the Company or the Holders of at least 25% in principal amount of the outstanding Securities may declare all the Securities to be due and payable immediately. If an Event of Default described in (vii) hereof occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal or interest) if it determines that withholding notice is in their interest.

Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

No director, officer, employee, incorporator or stockholder of the Company or a Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or such Subsidiary Guarantor under the Securities, this Indenture or a Subsidiary Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Securities by accepting a Security waives and releases all such liability to the extent permitted by applicable law. The waiver and release are part of the consideration for issuance of the Securities. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually signs the certificate of authentication on the other side of this Security.

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with rights of survivorship and not as tenants in common), CUST (= custodian) and U/G/M/A (= Uniform Gift to Minors Act).

The Company has caused CUSIP, Common Code or ISIN numbers, if applicable, to be printed on the Securities and have directed the Trustee to use CUSIP, Common Code or ISIN numbers, if applicable, in notices of redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

This Security shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company will furnish to any Securityholder upon written request and without charge to the Securityholder a copy of the Indenture. Requests may be made to:
