How to determine the weight of mild steel plate with different thicknesses

Construction Software

In this exclusive civil engineering article, vital guidelines are provided to find out the weight of mild steel plates in KG per square meter based on various thicknesses.

Suppose, the length and breadth of the mild steel plate is 1m x 1m, the weight will vary according to thickness of the plate. The thickness is here taken as 3 mm.

Given below, the detail thickness and weight of the mild steel plates with above dimension.

Thickness (mm) - Weight (Kg/Sq.M)

3 - 23.55
4 - 31.4
5 - 39.25
6 - 47.1
8 - 62.8
10 - 78.5
12 - 94.2
14 - 109.9
16 - 125.6
18 - 141.3
20 - 157
22 - 172.7
25 - 195.2
28 - 219.8

32 - 251.2
36 - 282.6
40 - 314
45 - 353.2
50 - 392.5
56 - 439.6
63 - 494.5
70 - 549.5

Initially, it is required to determine the volume of the plate based on the above dimension as follow :-

Volume = Length x Breadth x Thickness

After the values, we get the following result :-
Volume = 1 x 1 x 0.003 (after converting to meter)
Volume = 0.003 cubic meter

Before determining the weight, it is necessary to find out the density of the mild steel as follow :-
Density of mild steel (approx) = 7850 kg/m3

As we know, weight = volume x density
Weight = 0.003 x 7850 = 23.55 kg

The above method is applicable to find out the weight of the steel plate with different thicknesses.
