                      Filed by Butler Manufacturing Company
                             Pursuant to Rule 14a-12
                     of the Securities Exchange Act of 1934
                  Subject Company: Butler Manufacturing Company
                         Commission File No.: 001-12335

The following was filed by Butler Manufacturing Company ("Butler") with the
Securities and Exchange Commission ("SEC") under cover of a Current Report on
Form 8-K on February 17, 2004.

         On February 15, 2004, Butler and BlueScope Steel Limited, an Australian
         corporation ("BlueScope"), entered into an Agreement and Plan of Merger
         (the "Merger Agreement") pursuant to which BSL Acquisition Corporation,
         a wholly-owned subsidiary of BlueScope, will merge with and into Butler
         (the "Merger"), and Butler will become a wholly-owned subsidiary of
         BlueScope. A copy of the Merger Agreement is attached hereto as Exhibit
         99.1.

         Pursuant to the Merger Agreement, each outstanding share of Butler
         common stock will be exchanged for the right to receive $22.50 in cash.
         Each outstanding in-the-money option to acquire Butler common stock
         will be exchanged for the right to receive an amount equal to the
         product of (A) the difference between $22.50 and the exercise price per
         share of such option, and (B) the number of shares of Butler common
         stock covered by such option, less applicable withholding taxes. The
         Merger is conditioned upon, among other things, approval by Butler's
         stockholders, clearance under applicable antitrust laws and other
         customary conditions. Butler currently expects that the Merger will be
         consummated within 60-90 days.

         In connection with entering into the Merger Agreement, Butler's board
         of directors approved Amendment No. 1 (the "Rights Amendment") to the
         Rights Agreement dated as of September 16, 1998 (the "Rights
         Agreement") between Butler and UMB Bank, N.A., as rights agent, which
         was entered into on February 15, 2004. The Rights Amendment renders the
         Rights Agreement inapplicable to the transactions contemplated by the
         Merger Agreement. A copy of the Rights Amendment is attached hereto as
         Exhibit 99.2.

         Butler's press release announcing the Merger (the "Press Release") is
         attached hereto as Exhibit 99.3.



In connection with the merger, Butler will be filing a proxy statement and other
relevant documents concerning the transaction with the SEC. The proxy statement
will be mailed to the stockholders of Butler. BEFORE MAKING ANY VOTING OR
INVESTMENT DECISION WITH RESPECT TO THE MERGER, STOCKHOLDERS OF BUTLER ARE URGED
TO READ THE PROXY STATEMENT AND ANY OTHER RELEVANT DOCUMENTS FILED WITH THE SEC
WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT
THE MERGER. Investors and security holders can obtain free copies of the proxy
statement and other documents when they become available by contacting
Shareholder Relations, Butler Manufacturing Company, 1540 Genessee, Kansas City
Missouri 64102 P.O. Box 419917 (Telephone: (816) 968-3000). In addition,
documents filed with the SEC by Butler will be available free of charge at the
SEC's web site at www.sec.gov. You may also read and copy any reports,
statements and other information filed by Butler at the SEC public reference
rooms at 450 Fifth Street, N.W., Washington, D.C. 20549 or at the SEC's other
public reference rooms. Please call the SEC at 1-800-SEC-0330 for further
information on public reference rooms.

Butler and BlueScope and their respective executive officers and directors may
be deemed to be participants in the solicitation of proxies from the Butler
stockholders in favor of the Merger. Certain executive officers and directors of
Butler have interests in the merger, including, among others, change of control
payments, acceleration of and/or vesting of restricted stock, deferred
compensation and fees and stock options and their ownership of Butler's common
stock, and their interests will be described in the proxy statement when it
becomes available.
