National Mfg N266-106 Flat Steel Bar 3x48 in Hot-rolled

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N266-106 is a solid hot-rolled plain steel flat bar measuring 3 inches wide by 48 inches long and 0.125 inches thick. Designed for structural support in construction and industrial applications, this flat bar delivers consistent forming and welding characteristics suited to fabrication work. The hot-rolled plain steel construction provides reliable durability under load, and the uncoated surface accepts welds cleanly without special preparation. Licensed trade professionals and fabricators working on framing, bracing, and support assemblies will find this bar straightforward to cut, drill, and weld into place.

This flat bar is appropriate for both construction and industrial support applications where a weldable, formable steel stock is required. Its exterior-rated designation means it holds up in exposed environments. The 0.125-inch wall thickness and 3-inch width make it a practical choice for light structural supports, brackets, straps, and custom fabricated components across residential and commercial job sites.

Key Features

• 0.125 inches thick — suitable for light structural support and fabrication
• 3 inches wide by 48 inches long for versatile cut-to-fit applications
• Rated for exterior applications
• Meets ASTM Specification A1011 for hot-rolled sheet and strip steel
• Excellent forming characteristics allow bending and shaping without cracking

Compatibility

Designed as a general-purpose weldable flat steel bar for construction and industrial support applications. Suitable for use wherever ASTM A1011 hot-rolled plain steel flat stock is specified.

Installation Notes

Installation is typically performed by structural fabricators, ironworkers, or general contractors using standard metalworking tools including angle grinders, metal-cutting saws, and MIG or stick welders. Wear appropriate PPE including eye protection and gloves when cutting or welding. Follow applicable local building codes and OSHA guidelines for structural steel work. Inspect the bar for surface defects before integrating into any load-bearing assembly.
