National Mfg N180-042 Galvanized Flat Bar 1-1/4x36 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N180-042 is a solid galvanized flat bar measuring 1-1/4 inches wide by 36 inches long, designed for use in reinforcement, base plate, and structural support applications across construction and industrial settings. The hot-dip galvanized finish provides corrosion resistance suited for demanding environments. This flat bar can be drilled on-site to accommodate fasteners and custom layouts. It is not recommended for welding, as the galvanized coating produces hazardous fumes when exposed to welding heat and will degrade the zinc layer at the weld zone. Licensed contractors, ironworkers, and general tradespeople are the typical installers.

This flat bar is appropriate for light structural reinforcement, base plate fabrication, mounting brackets, and general industrial support work in both residential construction and commercial or industrial facilities. Its drillable profile makes it adaptable for custom configurations without specialized tooling. The corrosion-resistant galvanized finish extends service life in environments with moisture exposure. Each package contains 3 bars, making it practical for multi-point reinforcement tasks or staged project work requiring consistent material.

Key Features

• Solid galvanized flat bar with corrosion-resistant zinc finish
• Dimensions: 1-1/4 inches wide by 36 inches long
• Drillable for on-site custom fastener placement
• Not suitable for welding — galvanized coating produces hazardous fumes and degrades at weld points
• Suited for reinforcement, base plates, and structural support applications
• Sold in packages of 3 bars

Compatibility

Designed as a general-purpose solid galvanized flat bar for construction and industrial reinforcement, base plate, and support applications where a drillable, corrosion-resistant steel bar is required.

Installation Notes

Installation should be performed by qualified contractors or tradespeople familiar with structural fastening requirements applicable to the project. Power down or de-energize any adjacent electrical systems before drilling. Use appropriate PPE when drilling galvanized steel, as metal dust and zinc particles are a respiratory hazard. Do not weld this bar — galvanized coatings release zinc oxide fumes when heated, presenting a serious health risk and violating safe welding practices.
