Perforated Anti-Slip Surfaces

Fish-eye pattern perforated plate for anti-slip drainage flooring

Engineered with precisely punched and raised cone-shaped apertures that elevate above the metal surface, creating bi-directional traction, rapid liquid drainage, and passive airflow. Formed in heavy-duty carbon steel, 304/316 stainless steel, and structural aluminum.

Engineered Substrates

Carbon steel, 304 & 316 stainless, 5052-H32 / 6061-T6 aluminum

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.

Fish-eye anti-slip plates are punched and formed profile sheets with no direct product standard; profile dimensions, hole and dimple patterns, sheet thickness, and tolerances are confirmed per project and producing factory. Base-material and protective coating standards are referenced, and slip resistance is confirmed per project.
