Physical properties
Hardness: 4-6 (Mohs); Color: Metallic grey to black; Luster: Metallic; Structure: Rolled plate with raised diamond-shaped patterns; Cleavage: None; Specific Gravity: ~7.8
Formation & geological history
Manufactured through a hot-rolling process in industrial steel mills; not formed through geological processes. The pattern is stamped into the metal while hot.
Uses & applications
Used primarily in industrial flooring, stairs, catwalks, and truck beds to provide slip-resistant surfaces and durability in high-traffic areas.
Geological facts
Invented to prevent slips and falls on metal surfaces. While often called 'diamond plate,' it contains no actual diamonds; the name refers only to the aesthetic shape of the traction bumps.
Field identification & locations
Identify by its distinct repeating raised 'slug' or diamond pattern. It is commonly found in urban environments, industrial sites, and on toolboxes.
