Steel theoretical mass calculation formula
Note: The theoretical quality calculated by the formula has a certain discrepancy with the actual quality, and the error is generally about O. 2%~O. Between 7%, it can only be used as a reference for estimation. Http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn

Calculation example
Round steel wire rod
Kg/m
w=0.006165×d2
Where d is the diameter (mm)
Round steel with a diameter of 80mm, the quality per meter
Quality per meter = 0.0006165 × 802kg = 39.46kg
Rebar
Kg/m
W=0.00617×d2
Where d is the section diameter (mm)
Rebar with a section diameter of 12mm, for mass per meter
Mass per meter = 0.00617x122kg = 0.89kg
Square steel
Kg/m
W=0.00785×d2
Where d is the edge width (MM)
Square steel with a side width of 30mm, seeking mass per meter
Quality per meter = O. 00785×302kg=7.07kg
flat steel
Kg/m
W=0.00785×d×b
Where d is the side width (mm) b is the thickness (mm)
Flat steel with a width of 40mm and a thickness of 5mm, for the quality per meter
Quality per meter = O. 00785×40×5kg=1.57kg
Hexagonal steel
Kg/m
W = 0.006798 × d2
Where d is the distance to the opposite side (mm)
For hexagonal steel with a side distance of 50mm, find the mass per meter.
Quality per meter = 0.0006798 × 502kg = 17kg
Octagonal steel
Kg/m
W=0.006798×d2
Where d is the distance to the opposite side (mm)
For octagonal steel with a side distance of 80mm, find the mass per meter.
Mass per meter: 0.0065 x 802kg = 41.60kg
Equal angle steel
Kg/m
W=0.00785×[d(2b-d)+
0.215 (R2 - 2r2)]
Where b is the side width, d is the edge thickness, R is the inner arc _ radius, and r is the end arc radius
Find the mass per meter of 4mmx20mm equal angle steel
In GB9787, the R of 4mm×20mm equal angle steel is 3.5, r is 1.2.
Mass per metre = 0.00785 × [4 (2 × 20 - 4) + 0.215 (3.52 - 2 × 1.22)] kg = 1.15kg
Unequal angle steel
Kg/m
w=0.00785×[d(B+6-d)+0.215(R2~2 r2)]
Where B is the long side width, b is the short side, width, d is the side thickness, R is the inner arc radius, r is the end arc radius
Find the mass per metre of 30rnm × 20mm x 4mm unequal angle steel. From GB9788, it is found that 30x 20x 4 unequal angle steel has R of 3.5 and r is 1.2.
Mass per meter = 0.00785 × [4 (30 + 20 - 4) + 0.215 (3.52 - 2 × 1.22)] kg = 1.46kg
Channel steel
Kg/m
w=0.00785[hd+2t(b-d)+
0.349 (R2 - r2)]
Where h is high, b is leg length, d is waist thickness, t is the average leg thickness, R is the inner arc radius, and r is the end arc radius
Find the mass per square meter of 80mm × 43mm × 5mm channel steel. It is found from GB707 that the channel steel t is 8, R is 8, and r is 4
Mass per meter = 0.00785 [80 × 5 10 2 × 8 (43-5) + 0.349 (82-42)] kg = 8.04kg
I-beam
Kg/m
w=0.00785[hd+2t(b-d)+
0.8584 (R2 - r2)]
Where h is high, b is leg length, d is waist thickness, t is the average leg thickness, R is the inner arc radius, and r is the end arc radius
Find the mass per metre of I-beam of 250rnm × 118mm × 10mm. The I-beam t was found to be 13 from GB706. R is 10 and r is 5
Mass per meter = 0.00785 [250 × 10 + 2 × 13 x (118 - 10) + 0.8584 (102 - 52)] kg = 42.2 kg
Steel plate
Kg/m2
w=7.85×6
Where, 6 is thick
Steel plate with a thickness of 6mm, the quality per square meter
Quality per square meter = 7.85 × 6kg = 47.1kg
Steel pipe (including seamless steel pipe and welded steel pipe)
Kg/m
w=0.02466×S(D—S)
Where D is the outer diameter and s is the wall thickness
Seamless steel pipe with outer diameter of 60mm and wall thickness of 4mm, mass per meter of mass = 0.02466 × 4 × (60-4) kg: 5.52kg
