National Mfg N180-059 Galvanized Flat Bar 1-1/4x48 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N180-059 is a solid galvanized flat bar measuring 1-1/4 inches wide by 48 inches long, built for structural reinforcement and support in construction and industrial environments. The hot-dip or mill galvanized finish delivers corrosion resistance without the need for additional coating, making it well suited for exposed or semi-exposed installations. The bar can be drilled on-site to accept fasteners, anchor bolts, or connection hardware. It is not recommended for welding, as heat will compromise the galvanized zinc layer and may release hazardous fumes. Licensed contractors and general tradespeople working in structural, mechanical, or industrial settings are the primary installers.

This flat bar is designed for use as a reinforcement member, base plate component, or structural support in construction and industrial applications. Typical uses include bridging, strapping, bracing, and fabricating mounting plates where a pre-cut, corrosion-resistant steel section saves layout and cutting time on the job. It ships as a package of 2 bars, giving installers a matched pair for symmetric or redundant support configurations. No special surface prep is required before drilling, though standard metal-drilling bits and appropriate PPE apply.

Key Features

• Solid galvanized steel construction resists corrosion in construction and industrial environments
• 1-1/4 inch wide by 48 inch length ready for field drilling and fastening
• Designed for reinforcement, base plates, and structural support applications
• Can be drilled on-site to accept bolts, anchors, or connection hardware
• Not recommended for welding — galvanized coating degrades under welding heat
• Sold as a package of 2 solid flat bars

Compatibility

Designed as an OEM-style structural component for general construction and industrial reinforcement applications requiring a corrosion-resistant solid flat bar.

Installation Notes

Installation is typically performed by general contractors, ironworkers, or licensed tradespeople working in structural or mechanical capacities. Power down or de-energize any adjacent systems before drilling or fastening near electrical or mechanical equipment. Use standard HSS drill bits rated for steel when creating fastener holes, and wear appropriate PPE including eye protection and gloves. Do not attempt to weld this bar — the galvanized coating releases zinc oxide fumes when heated, creating a serious health hazard and compromising the structural integrity of the finish.
