1 basic formula for steel:
Angular steel = length* thick*0. 015
Welding tube/sutureless steel pipe = (extra-wall thickness)* wall thickness* 0. 02466
Pyramid = border length*4*0. 00785 = perimeter divided by 3. 14

Various formulas for the conversion of steel tubes by weight
The weight of the tube = 0. 25 x π (outside square-internal diameter square) x l x steel weight, of which: π 3. 14 l = length of the pipe 7. 8, so the weight of the tube = 0. 25 x 3. 14 x (outside square-internal diameter square) x l x 7. 8 * the weight result is calculated as kg (kg) if the size is taken in rice (m)
Steel density is 7. 85g/cm3 (note: unit conversion)
Steel theoretical weight calculation
The unit of measure calculated for the theoretical weight of steel is kg. Its basic formula is:
W (weight, kg) = f (disconnected area mm2) x l (long, m) x old (density, g/cm3) x 1/1000
