Exhibit 99.1 Press Release Issued September 5, 2007

Chaparral Steel Company Board Expresses No Opinion on the Tender Offer by Gerdau Ameristeel Corporation

for Chaparral’s 10% Senior Notes

Midlothian, Texas - September 5, 2007 - Chaparral Steel Company (NASDAQ: CHAP) today announced that its Board of Directors has elected to express no opinion and remain neutral toward the offer by Gerdau Ameristeel Corporation on August 30, 2007 to purchase any and all of Chaparral's outstanding 10% Senior Notes due 2013 and the related consent solicitation. The notes tender offer and related consent solicitation are being conducted in connection with Gerdau Ameristeel Corporation’s previously announced agreement to acquire Chaparral.

Chaparral indicated that its Board of Directors believes that each noteholder should make its decision as to whether to tender on an individual rather than a collective basis, based on that noteholder's particular circumstances. Chaparral further indicated that its Board believes the determination whether to tender is a financial decision to be made by each noteholder, in consultation with the noteholder's financial advisor, based on the terms of the offer being made by Gerdau Ameristeel Corporation. For these reasons, Chaparral believes that it is not appropriate for it to make a recommendation to noteholders regarding the tender of their notes and expresses no opinion as to the course of action that noteholders should take.

The announcements contained in this press release were made pursuant to Rule 14e-2 under the Securities Exchange Act of 1934.
