National Mfg N301-606 Expanded Sheet Metal 24x24 13GA

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N301-606 is a 24 x 24 inch expanded sheet metal panel fabricated from hot rolled plain steel at 13 gauge thickness. The open-grid pattern measures 3/4 inch per cell, making it well suited for ventilation, guarding, reinforcement, and general industrial or construction applications. At 19.98 pounds per panel, this is a heavy-duty sheet intended for structural and protective uses. Because the base material is plain steel with no applied coating, it must be protected with paint, primer, or a rust-inhibiting finish prior to or immediately after installation to prevent corrosion.

This expanded metal sheet is appropriate for a wide range of trade applications including HVAC equipment guarding, electrical enclosure screens, machine guards, stair treads, walkway grating, and general fabrication work. It ships in a package quantity of 3 panels per unit of measure. Fabricators, contractors, and maintenance technicians commonly use this product where a strong, open-mesh panel is needed at a standard 24 x 24 inch footprint.

Key Features

• 13 gauge hot rolled plain steel construction for high strength and rigidity
• 3/4 inch grid pattern provides airflow, visibility, and drainage while maintaining structural integrity
• 24 x 24 inch standard panel size suits common guarding and reinforcement layouts
• Expanded (not welded) mesh construction — no weld points to corrode or fail
• Must be coated or primed after installation to prevent corrosion in exposed environments
• Sold in packages of 3 panels

Compatibility

Designed as a general-purpose expanded metal panel for use in fabrication, guarding, ventilation, and reinforcement applications where a 24 x 24 inch, 13 gauge, 3/4 inch grid profile is specified.

Installation Notes

Installation is typically performed by fabricators, maintenance technicians, or contractors using standard metal cutting and fastening tools. Cut edges are sharp — wear appropriate cut-resistant gloves and eye protection during handling and fitting. Because this panel is plain hot rolled steel with no protective finish, apply a compatible primer or rust-inhibiting coating before or immediately after installation to prevent oxidation, especially in outdoor or high-humidity environments. Follow applicable local building or safety codes for guarding clearances and fastener requirements.
