Definition of Hot Rolled Checkered Steel Sheet
The hot rolled steel sheet with raised pattern on surface. The raised pattern could be shaped as rhombus,bean or pea. There is not only one kind of pattern on the checkered steel sheet, but also a complex of two or more than two kinds of pattern on surface of one checkered steel sheet. It also could be called as grid steel sheet.
Chemical Composition of Hot Rolled Checkered Steel Sheet
Our hot rolled checkered steel sheet is usually to roll with ordinary carlbon structure steel. The carbon content value can reach more than 0.06%,0.09% or 0.10%,the maximum value is 0.22%. The silicon content value ranges from 0.12-0.30%, the manganese content value ranges from 0.25-0.65%, and the phosphorus and sulphur content value is commonly less than 0.045%.
The Hot Rolled Checkered Steel Sheet possesses a variety of advantages, such as beauty in appearance,skip resistance and saving steel material.Generally speaking,in order to test the mechanical property or the quality of hot rolled checkered steel sheet, the shaping rate and the pattern height should be tested primarily.

Application of Hot Rolled Checkered Steel Plate
The hot rolled checkered steel sheet can usually be used in the industry of ship-building,boiler, automobile, tractor, train- building and architecture. In details, there are many demands for hot rolled checkered steel sheet to make floor, ladder at workshop, work frame pedal, ship deck, car floor and so on.
Package & Delivery of Hot Rolled Checkered Steel Plate
The items to be prepared for packing include: narrow steel strip, crude steel belt or edge angle steel, craft paper or galvanized sheet.
The hot rolled checkered steel plate should be wrapped with craft paper or galvanized sheet outside, and it should be bundled with narrow steel strip, three or two narrow steel strip in longitudinal direction,and the other three or two strips in transverse direction. Furthermore, in order to fix the hot rolled checkered steel sheet and avoid the strip at edge shall be broken, the crude steel belt cut into square should be put under the narrow steel strip on the edge. Of course, the hot rolled checkered steel sheet could be bundled without craft paper or galvanized sheet. It depends on customer's requirement.
In consideration of the transportation from mill to loading port, the truck will be usually used. And the maximum quantity for each truck is 40 mt.
