Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) Interest.

(a) Ryerson Inc., a Delaware corporation, or its successor (together, “Ryerson” or the “Company”), promises to pay interest on the principal amount of this Note (“12% Senior Secured Note” and, together with the Floating Rate Senior Secured Note, the “Notes”) at a fixed rate. Ryerson will pay interest in United States dollars (except as otherwise provided herein) semiannually in arrears on May 1 and November 1, commencing on May 1, 2008 or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the 12% Senior Secured Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including October 19, 2007; provided that if there is no existing Default or Event of Default in the payment of interest, and if this 12% Senior Secured Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date (but after October 19, 2007), interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of 12% Senior Secured Notes, in which case interest shall accrue from the date of authentication. Ryerson shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1 % per annum in excess of the then applicable interest rate on the 12% Senior Secured Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest rate on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

(b) Registration Rights Agreement. The Holder of this Note is entitled to the benefits of a Registration Rights Agreement, dated as of October 19, 2007, among Rhombus Merger Corporation (subsequently merged with and into Ryerson, “Rhombus”), the Guarantors party thereto and the Initial Purchasers.

(2) Method of Payment. Ryerson will pay interest on the 12% Senior Secured Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders of 12% Senior Secured Notes at the close of business on the May 1 and November 1 preceding the Interest Payment Date, even if such 12% Senior Secured Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The 12% Senior Secured Notes shall be payable as to principal, premium and interest at the office or agency of Ryerson maintained for such purpose within or without the City and State of New York, or, at the option of Ryerson, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds

Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Any payments of principal of and interest on this 12% Senior Secured Note prior to Stated Maturity shall be binding upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. The amount due and payable at the maturity of this Note shall be payable only upon presentation and surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes.

The terms of the 12% Senior Secured Notes include those stated in the Indenture and those made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). To the extent the provisions of this 12% Senior Secured Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The 12% Senior Secured Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The 12% Senior Secured Notes issued on the Issue Date are senior Obligations of Ryerson limited to $425,000,000 in aggregate principal amount, plus amounts, if any, sufficient to pay premium and interest on outstanding 12% Senior Secured Notes as set forth in Paragraph 2 hereof.

(c) In addition to the optional redemption of the 12% Senior Secured Notes in accordance with the provisions of the preceding paragraph, prior to November 1, 2010, the Company may, with the net proceeds of one or more Qualified Equity Offerings, redeem up to 35% of the aggregate principal amount of the outstanding 12% Senior Secured Notes (including Additional Notes that are 12% Senior Secured Notes) at a Redemption Price equal to 112% of the principal amount of thereof, together with accrued and unpaid interest thereon, if any, to the date of redemption; provided that at least 65% of the principal amount of 12% Senior Secured Notes then outstanding (including Additional Notes that are 12% Senior Secured Notes) remains outstanding immediately after the occurrence of any such redemption (excluding 12% Senior Secured Notes held by the Company or its Subsidiaries) and that any such redemption occurs within 90 days following the closing of any such Qualified Equity Offering.

(6) Mandatory Redemption. Except as set forth under Sections 3.9, 4.10 and 4.14 of the Indenture, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the 12%, Senior Secured Notes.

(7) Repurchase at Option of Holder.

(a) Upon the occurrence of a Change of Control, each Holder will have the right to require Ryerson to repurchase all or any part (equal to $2,000 and any integral multiple of $1,000 in excess thereof) of such Holder’s 12% Senior Secured Notes pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to the date of purchase. Within 30 days following any Change of Control, Ryerson will deliver a notice to each Holder describing the transaction or transactions that constitute the Change of Control setting forth the procedures governing the Change of Control Offer required by the Indenture.

(b) Upon the occurrence of certain Asset Sales, the Company may be required to offer to purchase 12% Senior Secured Notes.

(c) Holders of the 12% Senior Secured Notes that are the subject of an Offer to Purchase will receive notice of an Offer to Purchase pursuant to an Asset Sale or a Change of Control from Ryerson prior to any related Purchase Date and may elect to have such 12% Senior Secured Notes purchased by completing the form titled “Option of Holder to Elect Purchase” appearing below.

On and after the redemption date, interest ceases to accrue on the 12% Senior Secured Notes or portions hereof called for redemption.

The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and Ryerson may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. Ryerson need not exchange or register the transfer of any 12% Senior Secured Note or portion of a 12% Senior Secured Note selected for redemption, except for the unredeemed portion of any 12% Senior Secured Note being redeemed in part. Also, it need not exchange or register the transfer of any 12% Senior Secured Notes for a period of 15 days before a selection of 12% Senior Secured Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

If an Event of Default (other than an Event of Default specified in clause (8) above with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of or interest on the Notes, have been cured or waived as provided in the Indenture.

8

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (6) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (6) shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes.

If an Event of Default specified in clause (8) above occurs with respect to the Company, the principal of and any accrued interest on the Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Trustee may withhold from Holders notice of any Default (except Default in payment of principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the interest of the Holders to do so.

(13) Trustee Dealings with Ryerson. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for Ryerson, the Guarantors or their respective Affiliates, and may otherwise deal with Ryerson, the Guarantors or their respective Affiliates, as if it were not the Trustee.

(14) No Recourse Against Others. No director, officer, employee, stockholder, general or limited partner or incorporator, past, present or future, of the Company, the Guarantors or any of their respective Subsidiaries, as such or in such capacity, shall have any personal liability for any obligations of the Issuer under the 12% Senior Secured Notes, any Guarantee or the Indenture by reason of his, her or its status as such director, officer, employee, stockholder, general or limited partner or incorporator.
