The pattern roll steel patterns also known checker plate, its surface withdiamond or rib plate.
&Nbsp; steel patterns due to the surface with ribs, slide effect, can be used asbuilding floor, escalators, work frame pedal, ship deck, car floor etc..
Pattern plate specifications to the fundamental thickness (rib thicknessexcluding) said, with 2.5-8 mm 10 specifications. Diamond plate steel plate for1-3.
Class B common carbon steel rolling, the provisions of chemical composition meet the GB700 "ordinary carbon structural steel technical conditions".
Pattern plate of high no less than 0.2 times the thickness of the substrate;
Checkered steel plate according to the weight of the actual weight of deliveryor theory;
Mark example: made of Q235-A, size 4*1000*4000mm.
Peaberry pattern plate, mark it as: round bean plate Q235-A-4*1000*4000-GB/T 3277-91
Diamond pattern plate, mark it as: diamond pattern plate B 3-4*1000*4000-GB3277-82
Steel with hot-rolled state of delivery;
Checkered steel plate surface without bubble, scar, crack, folding andinclusion, plate without delamination.
The surface quality is divided into two levels:
The general accuracy: steel surface with a thin layer of oxide scale and rustallowed, due to other local defects on the surface of oxide scale formed offrough and height or depth exceeds the allowable deviation of the ancient.
Burr height is not obvious and not more than the individual trace lines highallows patterns. The largest area of a single defect pattern with the square of the length of not more than.
High precision: steel surface with a thin layer of oxide scale, allowing the rust and the height or depth of no more than other local defects of half thethickness tolerance.
Pattern intact, a height of not more than half of the tolerance of thickness of the local slight burr allowed patterns.
