A500 Carbon Steel Structural Tubing provides several advantageous qualities that make it a highly sought after construction material for structural load bearing applications. Some of the most recognizable beneficial qualities that A500 Carbon Steel Structural Tubing provides includes:
The ASTM A500 specifications state that manufactured carbon steel tubing must meet certain specifications before being sold for any type of project. The A 500 carbon steel spec sheet provides a convenient and simple way to check material standards before beginning your next project.
ASTM A500 spec states that welded tubing shall be made from flat-rolled steel using electric-resistance welding. Longitudinal butt joints of welded tubing shall be welded across its thickness in such a manner as to assure the structural design strength of the tubing section. Welded structural steel tubing is typically furnished without the removal of inside flash.
A500 carbon steel structural tubing is only manufactured from materials that match the criteria for carbon steel. The chemical composition for A500 is mostly iron with added carbon, manganese, phosphorus, sulfur, and copper. Check out the chart below for exact A500 carbon steel chemical specifications.
