Note: For mild steel diamond (chequer) / checker plate with a thickness of over 3mm (0.125 inch) (not including the height of the pattern), add about 5kg per square meter weight based on flat MS plate, add about 1.02 pound per square foot based on flat low carbon steel plate.

Steel Plate Weight Calculation Formula

To calculate the weight of the steel plate, the first step is to measure the length, width, and thickness of the steel plate to calculate the volume. The next step is to multiply the volume of the steel by the density to calculate the steel plate weight.

So, the rectangular steel plate weight calculation formula is:

Steel Plate Weight = Length x Width x Thickness x Density, or
Weight = Steel plate area x Steel plate weight per square meter (or square foot)

Density of Various Steel

The density of most mild steels is 7.85g/cm3 (0.284 lb/in3), these steels include ASTM A36, 1008, 1012, 1015, 1018, 1020; S235 (St37), S275, S355 (St52), SS400, Q195, Q235, Q345 (Q355) , etc.
The average density of medium carbon steel is 7.82g/cm3 (0.2825 lb/in3).
The average density of high carbon steel is 7.81g/cm3 (0.282 lb/in3)
For stainless steel, please refer to: Density of Stainless Steel

Steel Plate Weight Chart/Table

The following chart/table lists the weight of steel plate per square meter/square foot in metric and imperial unit.

Note: The thickness of checker plate does not include the height of checker.

For MS Plate (Low Carbon Steel Plate)
Note: Mild steel diamond (chequer) / checker plate with a thickness of over 3mm (not including the height of the pattern), add 5kg per square meter based on flat MS plate weight.
