CHICAGO — Bull Steel & Tube Inc. has filed for Chapter 7 bankruptcy liquidation, according to documents filed in U.S. Bankruptcy Court in California.

The Corona, Calif.-based structural steel, beam and ornamental iron supplier listed both its estimated assets and estimated liabilities at up to $50,000 each, per court documents filed Friday.

The company has between one and 49 creditors, according to court documents, which were signed by company president Jose Luis Ramirez Jr.

A list of creditors wasn’t immediately available, nor was it immediately clear Monday why the company had filed for bankruptcy liquidation.

Company comptroller Mike Freeman declined to comment Monday. Attorney Scott Hanssler, whose company represents Bull Steel & Tube in the case, didn’t immediately respond to a request for comment.

A meeting of creditors is scheduled for Dec. 18 in Riverside, Calif., court documents show.
