The NATIONAL MFG/SPECTRUM BRANDS HHI N316-364 is an aluminum diamond plate sheet used in decorative and functional surface applications. Measuring 24 inches by 12 inches at 0.010 gauge thickness, this sheet features a raised non-skid diamond pattern that adds grip and visual texture to finished surfaces. Aluminum construction keeps weight low while still providing resistance to heavy pressure loads. The material can be bent or formed into a variety of shapes, making it adaptable to custom installations. It is weather resistant and suitable for both indoor and outdoor use. Contractors, fabricators, and trade professionals use this sheet for trim, protective panels, and decorative surfacing work.
This diamond plate sheet fits a wide range of decorative and light fabrication applications. Its 24 by 12 inch format makes it suitable for small panel work, step covers, equipment trim, toolbox facing, and similar projects. Because it is aluminum, it resists corrosion in outdoor environments and does not add significant structural load. It can be cut with standard metal-cutting tools and formed without specialized equipment, making it accessible for field installations. The sheet ships in a package quantity of two units per order.
Designed as a general-purpose aluminum diamond plate sheet for decorative trim, light fabrication, and surface protection applications where a non-skid or textured aluminum panel is required.
Installation is typically performed by fabricators, contractors, or experienced trade professionals using standard metal-cutting and forming tools. Wear appropriate hand and eye protection when cutting or bending aluminum sheet. Edges may be sharp after cutting — deburr before final fitting. Secure using mechanical fasteners or adhesive appropriate for aluminum and the mating surface material.
