While designing steel structures in civil construction, we use steel plates, cut into various sizes for welding and bolting purposes.
Now, we will see the weight calculation procedure for the 3 most common types of mild steel plate cuttings.
1. Rectangular-shaped mild steel plate.
Let us consider the MS plate of size 3m×2m×6mm. as shown in the fig. below.

| Rectangular mild steel plate. |
Here, length L = 3m, breadth B = 2 m, and thickness T = 6mm = 0.006m
Here, length L = 2m, breadth B =2m. and thickness T = 6mm = 0.006m.
The volume of the steel plate
= [length × breadth × thickness ( depth)]
= [3m × 2m × 0.006 m ]
= 0.036 cubic meters.
As you know, the density of mild steel
=7850kg/ cubic meter.
Weight of the plate = volume × density
= 0.036 × 7850
= 282.6 kg.
2. Square-shaped mild steel plate.
Let us consider the MS plate of the size 2m × 2m ×6mm. as shown in the fig. below.

| Square mild steel plate. |
Here, length L = 2m, breadth B =2m. and thickness T = 6mm = 0.006m.
The volume of the mild steel plate
= [length × breadth × thickness (depth )]
= [2m × 2m × 0.006m. ]
= 0.024 cubic meter.
As you know, the density of mild steel
=7850kg/ cubic meter.
Weight of the plate = volume × density
= 0.024 × 7850
= 188.4 kg.
3. Circular-shaped mild steel plate.
Let us consider a circular steel plate of diameter 300mm. and thickness 5mm. as shown in the fig. below.
 |
| Circular mild steel plate. |
Here, diameter D = 300mm. = 0.3m, and thickness T = 5mm.= 0.005m.
The volume of the circular steel plate
= [π × (D × D) ÷ 4 × T]
= [3.142 ×( ( 0.3 ×0.3) /4) × 0.005]
= 0.0003535 cubic meter.
As you know, the density of mild steel
=7850kg/ cubic meter.
Weight of the plate = volume × density
=0.0003535 × 7850
= 2.775 kg.
