Identified in the quality GB9787seeking 4mmx20mm equilateral angle per meter 4mm × 20mm equilateral angle R 3.5 r 1.2 per meter quality = 0.00785 × 4 (2 × 20-4) +0.215 (3.5 ² 2 × 1.2 ²)] kg = 1.15kg |
Unequal angle | kg / m |
w = 0.00785 × [d (B +6- d) +0.215 (R ² -2 r ²)] wherein, B is a long-side width, b is the short side, width, d is the edge thickness, R is the radius of the inner arc, r for the end of the arc radius |
Seeking 30rnm × 20mm x 4mm unequal angle mass per meter. Detected from GB9788 30x 20x 4 unequal angle R 3.5 r 1.2 per meter quality = 0.00785 × [4 (30 +20-4) +0.215 (3.5 ² -2 × 1.2 ²)] kg = 1.46 kg |
Channel iron | kg / m |
w = 0.00785 [HD +2 T (BD) +0.349 (R ²-R2) wherein h is high, B for the leg length, d is the waist thick, t is the average legs thick, R is the radius of the inner arc, r is the terminal arc radius |
Seeking 80mm × 43mm × 5mm channel per meter quality. Detected from GB707 t of the channel 8, and R 8, R 4 per meter mass = 0.00785 [80 × 5 + 2 × 8 (43-5) +0.349 (8 ² -4 ²)] kg = 8.04kg |
I-beam | kg / m |
w = 0.00785 [HD +2 T (BD) +0.8584 (R ²-R ²)] wherein h is high, B for the leg length, d, t is the average legs thick waist thick, R is the radius of the inner arc, r is the terminal arc radius |
Seeking 250rnm × 118mm × 10mm H-beam mass per meter. T of the I-beam detected from GB706 13. R 10, r 5 per meter mass = 0.00785 [250 × 10 + 2 x 13 x (118 10) +0.8584 (10 ² -5 mm ²)] kg = 42.2kg |
Steel plate | kg / m² |
W = 7.85 × 6 wherein 6 is thick |
6mm thickness of steel plate, find the mass per square meter per square meter quality = 7.85 × 6kg = 47.1kg |
Steel pipe (including seamless steel pipe and welded steel pipe) | kg / m |
w = 0.02466 × S (DS) wherein D is the outer diameter, s is the wall thickness |
