Raised diamond-lug plate for high-traction surfaces
Choose rolled carbon steel, stainless steel 304/316, or aluminum plates built for secure footing and clean architectural lines.
Angled diamond pattern provides equal grip across lateral and longitudinal directional slip paths.
Continuous flat base channels speed up sweeping, power-washing, and chemical washdown cycles.
Rolled lugs remain ductile; bending and punching can be coordinated per project.
Continuous channels direct liquid runoff away from contact points.

Note: Values are typical reference data (typical, confirmed per project). Stainless steel 304/316 unit weights approximate carbon steel multiplied by factor 1.015. Material documentation (such as mill test reports) can be requested at quotation; availability depends on the product and the producing factory.
Processing options can be coordinated through selected in-house production or partner factories, subject to project requirements and confirmation.
Applicable standards
Listed as reference standards only, never certificates held by MutualMetal. The applicable standard, material grade, and documentation are confirmed per product and project.
The diamond (lentil / raised-diamond) pattern is covered by rolled-plate standards under different pattern designations; pattern style, thickness and tolerances are confirmed per project and producing factory.
