A simple way is to use the specification of the beam, most beams will have a specification saying how much it ways per meter or per foot.

Calculation.

weight = Area*Length*density

*Note that when calculating the weight of a beam for structures a safety factor which will be defined in you country design code

### How do you find the weight of 1 sqm of 10mm ms plate?

In order to find the weight of the sheet of steel we must first
calculate it's mass.
In order to do this we require the volume of the steel sheet
(which we can calculate) and the density of mild steel.
The steel sheet in question has a volume of 1 x 1 x 0.01 m3.
Mild steel has a density of 7800 kg/m3.[A]
As such the mass = 7800 x 0.01
mass = 78 kg
In order to calculate the weight (which is a force due to
gravitational acceleration acting on an object) we must multiply
the mass by g - the gravitational acceleration.
Weight = 78 x 9.81
Weight = 765.18 Newtons.
