DETAILS

Pattern pattern that is also known as textured plate steel plate, is the surface of diamond or ribbed plate.
Because of its surface rib plate, non-slip effect, can be used as the floor, factory escalator, working platform pedals, ship deck, car floor and so on.
The size of the pattern plate to the basic thickness (excluding the thickness of the ribs), there are 2.5-8 mm 10 specifications. Checkered plate with 1-3.
Class B plain carbon structural steel rolling, chemical composition in line with GB700 "ordinary carbon structural steel technical conditions" requirement.
Pattern board height not less than 0.2 times the substrate thickness;
Pattern plate according to the actual weight or theoretical weight delivery;
Marking example: made of Q235-A, size 4 * 1000 * 4000mm.
Round bean pattern plate, which is marked as: Round bean pattern plate Q235-A-4 * 1000 * 4000-GB / T 3277-91

Ordinary accuracy: The surface of the steel sheet is allowed to have a thin layer of scale, rust, surface roughness due to the scale off, and other local defects whose height or depth exceeds the allowable deviation.
Pattern is allowed on the obvious burr and no more than the height of the individual marks. The maximum area of ??a single defect does not exceed the square of the grain length.
Higher accuracy: a thin layer of scale on the steel surface, rust and other local defects of height or depth not to exceed half the thickness tolerance.
