AMENDMENT NO. 57

TO SCHEDULE 13D

This amended statement on Schedule 13D (this “Statement”) relates to the common stock, par value $0.01 per share (the “Shares”), of Keystone Consolidated Industries, Inc., a Delaware corporation (the “Company”). Items 2, 3, 4, 5, 6 and 7 of this Statement are hereby amended or supplemented as set forth below.

Item 2.

Identity and Background.

There is no change to the prior disclosure under this item except for the following.

(a) This Statement is filed by:

·	Contran Corporation (“Contran”) as a direct holder of Shares; and

·	by virtue of his position with Contran (as described in this Statement), Harold C. Simmons (collectively, the “Reporting Persons”)

By signing this Statement, each Reporting Person agrees that this Statement is filed on its or his behalf.

Contran and Mr. Simmons’ wife are the direct holders of approximately 88.0% and 0.1%, respectively, of the 12,101,932 Shares outstanding as of August 18, 2011 according to information furnished by the Company (the “Outstanding Shares”). Contran may be deemed to control the Company.

Substantially all of Contran’s outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Mr. Simmons (the “Trusts”), of which Mr. Simmons is the sole trustee, or held by Mr. Simmons or persons or other entities related to Mr. Simmons. As sole trustee of each of the Trusts, Mr. Simmons has the power to vote and direct the disposition of the shares of Contran stock held by each of the Trusts. Mr. Simmons, however, disclaims beneficial ownership of any shares of Contran stock that the Trusts hold.

Mr. Simmons is chairman of the board of Contran. By virtue of the holding of this office, the stock ownership and his service as trustee, as described above, (a) Mr. Simmons may be deemed to control Contran and the Company and (b) Mr. Simmons may be deemed to possess indirect beneficial ownership of the Shares directly held by Contran and his wife. However, Mr. Simmons disclaims beneficial ownership of the Shares beneficially owned by either of them.

Certain information concerning the directors and executive officers of Contran, including offices held by Mr. Simmons, is set forth on Schedule A attached hereto and incorporated herein by reference.

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 is hereby amended or supplemented as set forth below.

Pursuant to a stock purchase agreement (the “Stock Purchase Agreement”) dated August 16, 2011 Contran purchased the following Shares from the following sellers (the “Sellers”) at $9.43 per share as follows:

Seller	Shares Purchased from Seller		Aggregate Purchase Price

Corsair Capital Partners, L.P		657,228	$	6,197,660.04
Corsair Capital Partners 100, L.P		53,016		499,940.88

Corsair Long Short Partners, L.P.		3,400		32,062.00
		1,551,022	$	14,626,137.46

The purchase of these 1,551,022 Shares was privately negotiated between Contran and the Sellers, was not executed on the open markets and incurred no brokerage commissions. Under the terms of the Stock Purchase Agreement, among other things,

·	each of the Sellers or its affiliates agreed they would not, directly or indirectly, purchase Shares until after August 16, 2016;

·	each of the Sellers gave a general release to the Company and Contran and their respective officers, directors, employees and other affiliates; and

·	the Sellers agreed to disgorge to the Company short-swing profits under Section 16(b) of the Securities Exchange Act of 1934, as amended, in the aggregate amount of $105,715.48.

Contran borrowed under its existing revolving credit facility with PlainsCapital Bank to fund the purchase price for the 1,551,022 Shares. For the terms of the revolving credit facility see the:

Item 4.

Purpose of Transaction

Item 4 is hereby amended or supplemented as set forth below.

Contran purchased (the “Purchase”) the 1,551,022 Shares in order to increase its equity interest in the Company.

As a result of the Purchase, Contran’s ownership interest in the Company has exceeded the 80% ownership threshold necessary for the Company to become, and effective August 16, 2011 the Company became, a member of the group of companies consolidated for U.S. federal income tax purposes of which Contran is the parent corporation (the “Contran Tax Group”).

As part of becoming a member of the Contran Tax Group, the Company entered into a Tax Sharing Agreement dated August 16, 2011 with Contran (the “Tax Sharing Agreement”). In accordance with the Tax Sharing Agreement, Contran’s policy for intercompany allocation of income taxes provides that subsidiaries included in the Contran Tax Group compute their provision for income taxes on a separate company basis. Generally, subsidiaries make payments to or receive payments from Contran in the amounts they would have paid to or received from the Internal Revenue Service (“IRS”) had they not been members of the Contran Tax Group. The separate company provisions and payments are computed using the tax elections made by Contran. There are no tax elections that Contran will currently make that will have any impact on the Company. Consequently, the amount of payments for income taxes that the Company will make to or receive from Contran is not currently expected to differ from the amount of payments for income taxes that the Company would make to or receive from the IRS had the Company not become a member of the Contran Tax Group.

In addition, since the Company is now a member of the Contran Tax Group, the Company will be jointly and severally liable for the federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which the Company is included in the Contran Tax Group. However, Contran has agreed to indemnify the Company for any liability for income taxes of the Contran Tax Group in excess of the Company’s tax liability previously computed and paid in accordance with its tax allocation policy. As a member of the Contran Tax Group, the potential federal income tax liability for which the Company would become jointly and severally liable is currently not material, primarily because of net operating loss carryforwards that Contran currently has. As a result, becoming so jointly and severally liable is not expected to have any material effect on the Company’s financial position, results of operations or liquidity. In addition, in the event such potential federal income tax liability for which the Company is jointly and severally liable were to become material in the future, the Company would nevertheless not expect such liability to have any material effect on its financial position, results of operations or liquidity, as pursuant to the Tax Sharing Agreement, Contran has agreed to indemnify the Company with respect to the portion of such liability in excess of the Company’s own tax liability. The description of the Tax Sharing Agreement in this Statement is qualified in its entirety by the actual terms of the Tax Sharing Agreement filed as Exhibit 7 to this Statement.

On August 17, 2011, the Company announced it had determined not to proceed with its previously announced proposed subscription rights offering to the Company’s common stockholders and requested the withdrawal of the related registration statement on Form S-1 filed with the SEC. Such registration statement had not yet been declared effective by the SEC, nor had the Company actually commenced the proposed offering. The proposed offering contemplated participation by Contran as a subscribing party to the fullest extent possible. The Company’s commencement of, and Contran’s participation in, the proposed offering was subject to, among other things, the Company and Contran reaching an agreement on the terms of the proposed offering. Prior to reaching such agreement, Contran completed the Purchase. As a result of such Purchase, Contran has informed the Company that it no longer intends to subscribe for Shares in connection with the proposed offering. As disclosed in such registration statement, the Company had reserved the right to terminate or cancel the subscription rights offering at any time and for any reason.

Depending upon their evaluation of the Company’s business and prospects, and upon future developments (including, but not limited to, performance of the Shares in the market, availability of funds, alternative uses of funds, stock market and general economic conditions), the Reporting Persons or other persons or entities that may be deemed to be related to them, may in the future from time to time purchase Shares, and they or other entities that may be deemed to be related to them may from time to time dispose of all or a portion of the Shares held by such persons or entities, or cease buying or selling Shares. Any such additional purchases or sales of Shares may be in open market or privately negotiated transactions or otherwise.

As described herein, Mr. Simmons, through Contran, may be deemed to control the Company.

The persons named in Schedule A to this Statement are officers and/or directors of the Company or perform services for the Company as employees of Contran and may acquire Shares from time to time pursuant to employee benefit plans that the Company sponsors or other compensation arrangements with the Company or otherwise.

Except as described in this Statement, none of the Reporting Persons nor, to the best knowledge of such persons, any other person named in Schedule A to this Statement has formulated any plans or proposals that relate to or would result in any matter required to be disclosed in response to paragraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

There is no change to the prior disclosure under this item except for the following.

(a) The following entities or persons directly hold the following Shares:

Reporting Person	Shares Directly Held

Contran		10,647,401

Total		10,660,858

By virtue of the relationships described under Item 2 of this Statement, Mr. Simmons may be deemed to be the beneficial owner of the 10,660,858 Shares (approximately 88.1% of the Outstanding Shares) that Contran and his wife directly hold. Mr. Simmons disclaims beneficial ownership of any Shares that he does not hold directly. Mrs. Simmons disclaims beneficial ownership of any Shares that she does not hold directly

(b) By virtue of the relationships described under Item 2 of this Statement:

(2) Mr. Simmons and his wife may be deemed to share the power to vote and direct the disposition of the 13,457 Shares (approximately 0.1% of the Outstanding Shares) that his wife holds directly.

(d) Contran and Mr. Simmons’ wife each has the right to receive and the power to direct the receipt of dividends from, and proceeds from the sale of, the Shares it or she directly holds.

Item 6.
