Table of equivalent standards for Hot Rolled Steel: *
 
* The standards entered above are only equivalent and are not absolutely identical with each other.
There may be slight differences in mechanical properties, or in their chemical analysis, or in the results range.
 
CHECKERED PLATES
Checkered plate, or tear drop plate as it is also known, is used for industrial floor surfaces, or steps in industrial buildings.
The plate is made of hot rolled steel, on which there are lengthwise and crosswise protrusions providing skid prevention, and prevention of forming of liquids on the surface because of the unique nature of the protrusions on the plate.
 
Mechanical properties:
Manufactured from hot rolled steel plate of ST-37 type according to standard.
The surface was designed for lengthwise and crosswise protrusions that allow passage of liquids on one hand and skid prevention on the other.
The plate is suited for welding, galvanization, punching and bending.

PICKLED AND OILED STEEL
Pickled steel is a hot rolled steel sheet that undergoes a pickling and oiling process.
As a result of this process the sheet receives workability properties such as deep tension like that of cold rolled steel, and therefore it sometimes constitutes an economic solution for use of cold rolled steel sheets. Its main uses are in deep tension products, gas tanks etc.
