| Round steel, wire rod,(kg/m) |
W=0.006165*d*d |
D = diametermm |
The diameter of 10mmEach round steel,mThe weight.every mThe weight of the= 0.006165x10x10=0.6165kg |
| rebar (kg/m) |
W=0.00617*d*d |
D = diameter sectionmm |
The section diameter of 12mmRebar, eachmThe weight of the.every mThe weight of the= 0.00617x12x12=0.89kg |
| party steel (kg/m) |
W=0.00785*a*a |
A = edge widthmm |
Edge width 20mmEach square steel,mThe weight of the.every mThe weight of the= 0.00785x20x20=3.14kg |
| flat steel (kg/m) |
W=0.00785*b*d |
D = thickmm b=Edge widthmm |
Edge width 40mmThick,5mmFlat steel, eachmThe weight of the.everymThe weight of the= 0.00785x40x5=1.57kg |
| Six Angle steel (kg/m) |
W=0.006798*s*s |
S = to edge distancemm |
The edge distance 50mmSix Angle steel, eachmThe weight.every mThe weight of the= 0.006798x50x50=17kg |
| Eight Angle (kg/m) |
W=0.0065*s*s |
S = to edge distancemm |
The edge distance 80mmEight Angle, eachmThe weight of the.everymThe weight of the= 0.0065x80x80=41.62kg |
| Equal Angle steel (kg/m) |
W=0.00785*[d(2b-d)+0.215(R*R-2r*r)] |
B = edge widthR=D = edge thick inner arc radiusr=End arc radius |
o 20mmx4mmEach of equal Angle steelmThe weight.Find out from the metallurgical product catalog4mmx20mmOf equal Angle steelRfor3.5，rfor1.2.each mThe weight of the= 0.00785x[4X (2xTwenty - four）+ 0.215X (3.5x3.5 2x1.2x1.2）]=1.15kg |
| Unequal Angle (kg/m) |
W=0.00785*[d(B+b-d)+0.215(R*R-2r*r)] |
B = long edge width b=Short side wide
D=Edge thicknessr=End arc radius
R=Inner arc radius |
o 30mmx20mmx4mmUnequal Angle of eachmThe weight.Find out from the metallurgical product catalog30mmx20mmx4mmOf equal Angle steelRfor3.5，rfor1.2.each mThe weight of the= 0.00785x[4X (32 + 20-4）+ 0.215X (3.5x3.5 2x1.2x1.2）]=1.48kg |
| slot steel (kg/m) |
W=0.00785×[hd+2t(b-d)+0.349(R*R-r*r)] |
H = high d=Waist thick b=Legs are long
R=Inner arc radius t=The average thick legs |
o 80mmx43mmx5mmThe channel of eachmThe weight.Find out channel steel from the metallurgical product catalogtfor8、Rfor8、rfor4.each mThe weight of the= 0.00785x[80x5 + 2x8X (43-5）+ 0.349X (8x8-4x4）]=8.04kg |
| I iron (kg/m) |
W=0.00785×[hd+2t(b-d)+0.615(R*R-r*r)] |
H = high d=Waist thick b=Legs are long
R=Inner arc radius t=The average thick legs |
o 250mmx118mmx10mmThe beams of eachmThe weight.Find out from the metallurgical product catalogtfor13、Rfor10、rfor5, each mThe weight of the= 0.00785x[250x10 + 2x13（The 118-10）+ 0.615X (10xTen to fivex5）] |
| steel plate (kg/㎡) |
W=7.85*d |
D = thickness |
The thickness of the 4mmSteel plate, the weight per ㎡.Weight per ㎡= 7.85x4=31.4kg |
| Steel pipe[includingSeamless steel pipeAnd welded steel pipe] (kg/m) |
W=0.02466*s(d-s) |
D = diameters=Wall thickness |
Outside diameter of 60, wall thickness,4Seamless steel pipe, eachmThe weight.every mThe weight of the= 0.02466x4X (60-4）=5.52kg |
