Square Steel Tube is a welded structural grade tubing that is available in either type A513 or A500 Grade B,

depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication,

manufacturing and repairs. Steel square tube is widely used in industrial maintenance, agricultural implements,

transportation equipment, truck beds, trailers, frames, etc. Its box-shape configuration allows for much greater
