National Mfg N316-224 Steel Flat Bar 1.5x72 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N316-224 is a solid steel flat bar measuring 1.5 inches wide by 72 inches long, manufactured from hot-rolled plain steel for use as a structural support in construction and industrial applications. Hot-rolled plain steel provides reliable strength alongside excellent forming and welding characteristics, making this flat bar well suited for fabrication work. It meets ASTM Specification A36, a widely recognized standard for structural carbon steel. Licensed contractors, ironworkers, and general tradespeople typically specify this product for framing supports, bracing, and custom fabrication tasks.

This flat bar is intended for exterior construction and industrial support applications where an ASTM A36-compliant steel bar stock is required. It is sold as a single piece per package and is appropriate for projects that involve cutting, welding, or forming operations. It is not suitable for applications involving heat-treating, forging, or cold-drawing. Typical use cases include structural supports, mounting plates, straps, and general metal fabrication in both residential construction and light industrial settings.

Key Features

• Hot-rolled plain steel construction meets ASTM Specification A36 for structural carbon steel
