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.
Crocodile-mouth anti-slip plates are punched and formed profile sheets. They are not hot-rolled checkered plate, so GB/T 33974, ASTM A786, and DIN 59220 do not define them. There is no direct product standard; tooth profile, opening geometry, sheet thickness, and tolerances are confirmed per project and producing factory. Base-material and protective coating standards are referenced above, and slip resistance is confirmed per project.
