CHICAGO – September 21, 2007—Rhombus Merger Corporation (the “Purchaser”), a wholly owned subsidiary of Rhombus Holding Corporation (“Parent”), has commenced a cash tender offer and consent solicitation (together, the “Offer”) for any and all of the $150,000,000 aggregate principal amount of 8.250% Senior Notes due 2011 of Ryerson Inc. (“Ryerson”) (CUSIP No. 78375PAG2) (the “Notes”). Merger Sub was formed solely for the purpose of merging with and into Ryerson, which will be the surviving corporation of the merger and a wholly owned subsidiary of Parent.

In connection with the Offer, the Purchaser is soliciting consents to certain proposed amendments to eliminate substantially all of the restrictive covenants, certain events of default and related provisions in the indenture governing the Notes. Holders may not tender their Notes without delivering consents or deliver consents without tendering their Notes.

Holders who validly tender their Notes prior to 5:00 p.m., New York City time on October 4, 2007 (such date, as it may be extended, the “Consent Payment Deadline”) and such Notes are accepted for payment by the Purchaser will receive the Total Consideration (as discussed below) per $1,000 principal amount of Notes and accrued and unpaid interest up to, but not including, the initial payment date, which is expected to be October 19, 2007 (the “Initial Payment Date”). Holders who tender their Notes after the Consent Payment Deadline but on or prior to 8:00 a.m., New York City time on October 22, 2007 (the “Expiration Date”, unless extended) will receive the Total Consideration per $1,000 principal amount of Notes validly tendered and not withdrawn, less the consent payment of $30.00 per $1,000 principal amount of Notes.

The following table summarizes terms material to the determination of the Total Consideration to be received in the Offer per $1,000 principal amount of Notes validly tendered and not withdrawn prior to the Consent Payment Deadline:

CUSIP No.	Outstanding Aggregate Principal Amount		Note Description	First Redemption Date	First Redemption Price per $1,000 principal amount		Consent Payment per $1,000 principal amount		Reference Security	Reference Page	Fixed Spread

The Total Consideration per $1,000 principal amount of Notes validly tendered and not withdrawn prior to the Consent Payment Deadline will be calculated based on the present value on the payment date of the sum of the First Redemption Price on the First Redemption Date plus interest payments through the First Redemption Date, determined using a discount factor equal to the yield on the Price Determination Date (as defined
