Table 1
name | unit | Calculation formula | Note |
Round steel, wire rod | Kg/m | W=0.006165×d2 d=diameter (mm) | |
Rebar | Kg/m | W=0.00617×d2 d=section diameter (mm) | |
Square steel | Kg/m | W=0.00785×d2 d=side width (mm) | |
flat steel | Kg/m | W=0.00785×d×b d=side width (mm) b=thickness (mm) | |
Hexagonal steel | Kg/m | W=0.006798×d2 d=edge distance (mm) | |
Octagonal steel | Kg/m | W=0.0065×d2 d=edge distance (mm) | |
Equal angle steel | Kg/m | W=0.00785×[d×(2b-d)+0.215(R2-2r2)] b = side width d = side thickness R = inner arc radius r = end arc radius | |
Unequal angle steel | Kg/m | W=0.00785×[d(B+bd)+ 0.215(R2-2r2)] B = long side width b = short side width d = side thickness R = inner arc radius r = end arc radius | |
Channel steel | Kg/m | W=0.00785×[hd+2t(bd)+ 0.349(R2-r2)] H=high b=leg length d=waist thickness t=average leg length R=inner arc radius r=end arc radius | |
I-beam | Kg/m | W=0.00785×[hd+2t(bd)+ 0.8584(R2-r2)] H=high b=leg length d=waist thickness t=average leg length R=inner arc radius r=end arc radius | |
Steel plate | Kg/m2 | W = 7.85 × b b = thick | |
Steel pipe (seamless and welded steel pipe) | Kg/m | W=0.02466×S(DS) D=outer diameter S=wall thickness |
Note: Since the profile has a tolerance value during the manufacturing process, the theoretical weight calculated by the formula has a certain difference from the actual weight.
(The error is generally between 0.2 and 0.7%) and can only be used as a reference for estimation.
