The basic formula of steel

Angle steel=side length * side thickness * 0.015

Welded pipe/seamless steel pipe=(outer diameter wall thickness) × wall thickness × zero point zero two four six six

Square tube=side length × four × 0.00785=perimeter/3.14

Rectangular tube=(length+width) × two × wall thickness × zero point zero zero seven eight five

Flat steel=width * wall thickness * 0.00785

Galvanized flat steel=width × wall thickness × zero point zero zero seven eight five × one point zero six

Plate=length × width × thickness × zero point zero zero seven eight five

Patterned plate=[thickness] × 0.0785+0.3] × Length * width

Hexagonal steel=opposite side × Opposite edge distance × zero point zero zero six five

Octagonal steel=opposite side × Opposite edge distance × zero point zero zero six five

Stainless steel plate=length × width × thickness × seven point nine three

Weight of round steel (kg)=0.00617 × diameter × diameter × length

Weight of square steel (kg)=0.00785 × Edge width × Edge width × length

Weight of hexagonal steel (kg)=0.0068 × Opposite width × Opposite width × length

Weight of octagonal steel (kg)=0.0065 × Opposite width × Opposite width × length

Weight of threaded steel (kg)=0.00617 × Calculate diameter × Calculate diameter × length

Weight of angle steel (kg)=0.00785 × (Edge width+edge width - edge thickness) × Edge thickness × length

Flat steel weight (kg)=0.00785 × thickness × Edge width × length

Steel pipe weight (kg)=0.02466 × wall thickness × (Outer diameter wall thickness) × length

Calculation of hexagonal volume

Formula s20.866 × H/m/k is the opposite side × Opposite edge × zero point eight six six × Height or thickness

Formula for weight conversion of various steel pipes (materials)

Weight of steel pipe=0.25 × π × (Outer diameter square inner diameter square) × L × Specific gravity of steel

Among them: π=3.14, L=length of steel pipe, specific gravity of steel taken as 7.8

So, the weight of the steel pipe is 0.25 × three point one four × (Outer diameter square inner diameter square) × L × seven point eight

*If the unit of measurement is in meters (M), the calculated weight result is kilograms (Kg)

The density of steel is 7.85g/cm3 (note: unit conversion)

The unit of measurement for calculating the theoretical weight of steel is kilograms (kg).

The basic formula is:

W (weight, kg)=F (cross-sectional area mm2) × L (length, m) ×ρ (Density, g/cm3) × 1/1000
