Re: Longhai Steel Inc./Registration Statement on Form S-1

Ladies and Gentlemen:

We have acted as special Nevada counsel to Longhai Steel, Inc., a Nevada corporation (the "Company"), in connection with the registration by the Company of 2,560,006 shares (the "Shares") of its common stock, $0.001 par value per share (the "Common Stock"), to be sold by certain selling stockholders ("Selling Stockholders") of the Company under a Registration Statement on Form S-1 (Amendment No. 4), Registration No. 333-183949 (the "Registration Statement") as filed with the Securities and Exchange Commission (the "Commission"). Of the 2,560,006 Shares subject to the Registration Statement, 1,600,003 of such Shares (the "Issued Shares") are issued and outstanding and 960,003 of such shares (the "Warrant Shares") are to be issued upon exercise of certain Common Stock Purchase Warrants ("Warrants") held by the Selling Stockholders . The Issued Shares and the Warrants were issued pursuant to a certain Securities Purchase Agreement dated May 11, 2012 among the Company and the Selling Stockholders (the "Purchase Agreement"). The Issued Shares and the Warrant Shares are referred to herein collective as the "Securities."

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of: (i) the Registration Statement; (ii) the Amended and Restated Articles of Incorporation of the Company, as filed with the Secretary of State of Nevada on July 9, 2012; (iii) the Amended and Restated Bylaws of the Company, as adopted on March 22, 2012; (iv) the Purchase Agreement; (v) a form of the Warrants; (vi) a specimen certificate representing the Common Stock; and (vii) certain resolutions of the Board of Directors of the Company relating to the issuance of the Securities, the registration of the Securities under the Securities Act, and such other matters as relevant. We also have examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others, and such other documents, certificates, and records as we have deemed necessary or appropriate as a basis for the opinions set forth herein.

In our examination we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to original documents of all documents submitted to us as facsimile, electronic, certified, or photostatic copies. We have relied upon the accuracy and completeness of the information, factual matters, representations, and warranties contained in such documents. In our examination of documents, we have assumed that the parties thereto, other than the Company, had the power, corporate or other, to enter into and perform all obligations thereunder, and, other than with respect to the Company, the due authorization by all requisite action, corporate or other, the execution and delivery by all parties of the documents, and the validity and binding effect thereof on such parties. We have also assumed that the Purchase Agreement and Warrants will each be enforceable in accordance with the terms thereof.
