National Mfg N316-166 Steel Flat Bar 3/4 X 36 in Construction

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N316-166 is a solid hot-rolled plain steel flat bar measuring 3/4 inch wide by 36 inches long. It is designed to serve as a structural support in construction and industrial applications. The hot-rolled plain steel construction delivers reliable strength along with excellent forming and welding characteristics, making it straightforward to cut, shape, and join on the job site. This flat bar meets ASTM Specification A1011, confirming it is produced to a recognized standard for hot-rolled sheet and strip steel. It is suited for exterior use and is handled primarily by contractors, ironworkers, and general tradespeople.

This flat bar is well-suited for light structural support work, bracing, strapping, and fabrication tasks in both residential and commercial construction settings. Its compact 36-inch length makes it practical for smaller framing, reinforcement, and repair projects where a full-length bar is unnecessary. The hot-rolled plain steel finish accepts paint and coatings readily, which is useful when the bar will be exposed to outdoor conditions over extended periods.

Key Features

• Hot-rolled plain steel construction for durability in demanding jobsite conditions
• Excellent forming and welding characteristics for easy fabrication and field modification

Installation Notes

Installation is typically performed by contractors, fabricators, or ironworkers using standard metal-working tools including angle grinders, drill presses, and welding equipment. Always power down any adjacent electrical systems and follow applicable local building codes before cutting or welding in place. Wear appropriate PPE including eye protection and gloves when cutting or grinding. For exterior installations, apply a suitable primer or coating to exposed surfaces to slow corrosion.
