    Nothing in this form shall be construed to imply that the Commission has
                   verified any information contained herein.

If the notification relates to a portion of the filing checked above, identify
the Item(s) to which the notification relates:

PART I - REGISTRANT INFORMATION

      Bayou Steel Corporation
Full Name of Registrant

      N/A
Former Name if Applicable

      138 Highway 3217, P.O. Box 5000
Address of Principal Executive Office (Street and Number)

      LaPlace, Louisiana 70069
City, State and Zip Code

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should

      (a) The reasons described in reasonable detail in Part III of this form
      could not be eliminated without unreasonable effort or expense;


                                     Page 1


|X|   (b) The subject annual report, semi-annual report transition report on
      Form I O-K, Form 20-F, 11-K or Form N-SAR, or portion thereof, will be
      filed on or before the fifteenth calendar day following the prescribed due
      date; or the subject quarterly report or transition report on Form 10-Q,
      or portion thereof will be filed on or before the fifth calendar day
      following the prescribed due date; and (c) The accountants statement or
      other exhibit required by Rule 12b-25(c) has been attached if applicable.

PART III - NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,
N-SAR, or the transition report portion thereof, could not be filed within the
prescribed time period.

      On January 22, 2003, the Company and its subsidiaries Bayou Steel
      Corporation (Tennessee), and River Road Realty Corporation (collectively,
      the "Debtors") filed a voluntary petition for reorganization under Chapter
      11 of the United States Bankruptcy Code. The petition requesting an order
      for relief was filed in United States Bankruptcy Court, Northern District
      of Texas (the "Bankruptcy Court"), where the case is now pending before
      the Honorable Barbara J. Houser, Case No. 03-30816 BJH (the "Petition
      Date"). The Company intends to continue normal operations and does not
      currently foresee any interruption in the shipment of product to customers
      in the near term. The Company is managing its business subsequent to the
      Petition Date as debtor-in-possession subject to Bankruptcy Court approval
      and oversight. The attention of the Company's financial and accounting
      group to the various filings required in the bankruptcy proceedings and to
      related liquidity issues precluded the completion of the Form 10- Q
      without unreasonable effort and expense.

PART IV- OTHER INFORMATION

(1) Name and telephone number of person to contact in regard to this
notification

     Richard J. Gonzalez            985                       652-4900
   -----------------------    ------------------      ------------------------
           (Name)                (Area Code)             (Telephone Number)

(2) Have all other periodic reports required under Section 13 or 15(d) of the
Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of
1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If answer is no,
identify report(s). |X| Yes |_| No

(3) Is it anticipated that any significant change in results of operations from
the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?
|X| Yes |_| No

If so, attach an explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable estimate
of the results cannot be made.

The net loss, before applying the Statement of Financial Accounting Standards
No. 144 - Accounting for the Impairment or Disposal of long-Lived Assets ("SFAS
144"), was approximately $9 million and $5 million in the second quarter of
fiscal 2003 and 2002, respectively. Net loss increased approximately $4 million
in the second quarter of fiscal 2003 compared to the second quarter of fiscal
2002 due to three factors. First, metal margin was eroded due to the price of
scrap increasing more than the selling price of the finished product. Second,
conversion cost increased due to escalating fuel prices. Third, the Company
incurred over $1.5 million in


                                     Page 2


consulting, legal and other restructuring charges in dealing with its default on
its first mortgage notes and line of credit agreement. The Company is completing
its analysis required under SFAS 144; this could result in a non- cash charge to
the quarterly results.

                  (Name of Registrant as Specified in Charter)
