Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N215-699 is a plain steel square tube measuring 0.5 inches by 48 inches, manufactured from hot rolled plain steel using an electric resistance welded (ERW) process. It meets ASTM specification A513, confirming consistent dimensional tolerances and mechanical properties. This tube is a standard structural steel section used in fabrication and general-purpose construction projects. It is handled and installed by metalworkers, general contractors, welders, and industrial fabricators working across commercial and light industrial settings.

This tube is suited for a wide range of structural and fabrication applications including frames, railings, truck racks, gates, and other commercial or industrial assemblies. Its ERW construction and hot rolled plain steel finish make it a practical choice for projects where a paintable or weldable surface is required. The 48-inch length fits common cut-to-length workflows and can be further processed with standard metal cutting and welding equipment. It is sold in a package quantity of 3 units.
