Square Tube, Hollow Section Structural Steel Square & Rectangular Tube    

Square Steel Tubing - A500B(C) / A513-1 ,Mechanical Steel Tubing ,Hot Rolled Mild Steel Square Tube A513

Produced by cold forming flat rolled steel into tubular shapes and electric-resistance welded into solid wall tubing. Controls during the cold forming to square or rectangular shapes prevent irregularities in structure or loss of physical properties across the weld area. Since it begins as a flat rolled product, the finished tube has a uniform wall thickness and equal strength throughout. It is easy to machine and fabricate, using all common machining and fabricating operations. It can be bent or drawn, flattened or flared, expanded or swaged, drilled or punched easily. It is easily mechanically joined or welded using all the commonly used practices. Because of ease of fabrication, and a surface suitable for painting or plating, Structural Steel Square and Rectangular tube has almost unlimited applications.
