How to select steel for building construction?
1-check Diameter & grade of steel-
So first of all you have to check the diameter of the steel and also the grade of steel we have different grades of steel 40,60, and 75 .so must check the diameter and grade of the steel before buying.
2. Check the weight of the steel-
Here is an example to check the weight of steel. if we have an 8 mm diameter steel bar and a length is 12 meters so the weight of the steel-
FORMULA TO CALCULATE WEIGHT OF STEEL = D²L/162
given data
D = 8 mm, L = 12 meter
So the weight of steel = ( 8 x 8 x 12)/162
weight of steel = 4.74 kg
3. Check for rust and loose Coating-
if you wanna purchase you have to check for rust and lose coating .it should not be rust and it should not be loose if there is loose coating in steel don't for building construction.
4. Check for cracks-
If we bend the steel 180 degrees so the surface the of steel is the top surface of the steel should not be white and it should not be developed any cracks. it's very important so don't you this steel
5. Never store steel on the ground-
sometimes we placed steel on the ground that steel should rust and rusted steel should not be used in building construction otherwise it will make more problems and rust can weaken the strength of the steel remember these points. if you wanna store steel on the ground so it should be up from the ground mini 4 inches .
So these are some important tips before purchasing steel.
