Most of my customer asking the formula for calculating weight of steel plate，When they were going to purchasing 4140 plate.for steel stockist,most of them did the procurement base on ton,but for some trading company and some factory,which is the end users,they would like to buy base on pieces unit.however,as a steel wholesaler,most of the order are charged by tons,that some company they wanna calculate advance by themselves，to estimate the cost .
So now,I try to collect most of the steel formula here.
Formula for calculating weight of steel plate
Formula: 7.85 × length (m) × width (m) × thickness (mm)
Example: steel plate 6m (length) × 1.51m (width) × 9.75mm (thickness)
Calculation: 7.85 × 6 × 1.51 × 9.75 = 693.43kg
Steel tube weight calculation formula
Formula: (outer diameter-wall thickness) × wall thickness mm × 0.02466 × length m
Example: 114mm (outer diameter) x 4mm (wall thickness) x 6m (length) of steel pipe
Calculation: (114-4) × 4 × 0.02466 × 6 = 65.102kg
Round steel weight calculation formula
Formula: diameter mm × diameter mm × 0.00617 × length m
Example: Round steel Φ20mm (diameter) × 6m (length)
Calculation: 20 × 20 × 0.00617 × 6 = 14.808kg
Square steel weight calculation formula
Formula: side width (mm) x side width (mm) x length (m) x 0.00785
Example: Square steel 50mm (side width) x 6m (length)
Calculation: 50 × 50 × 6 × 0.00785 = 117.75 (kg)
Flat steel weight calculation formula
Formula: side width (mm) x thickness (mm) x length (m) x 0.00785
Example: Flat steel 50mm (edge width) x 5.0mm (thickness) x 6m (length)
Calculation: 50 × 5 × 6 × 0.00785 = 11.7.75 (kg)
Hexagonal steel weight calculation formula
Formula: Opposite diameter × Opposite diameter × Length (m) × 0.00068
Example: Hexagonal steel 50mm (diameter) x 6m (length)
Calculation: 50 × 50 × 6 × 0.0068 = 102 (kg)
Rebar weight calculation formula
Formula: Diameter mm × diameter mm × 0.00617 × length m
Example: Rebar Φ20mm (diameter) × 12m (length)
Calculation: 20 × 20 × 0.00617 × 12 = 29.616kg
