钢材重量计算
选择截面，输入长度和数量，即可得到每米质量、单件质量、总质量和吨数。
结果 – PL20 (per 1000 mm width)
每米质量157.00kg/m
单件质量942.00kg
总质量942.00kg
总吨数0.942t
1 × PL20 (per 1000 mm width) @ 6.000 m
方法与假定
Mass per piece = m × L ; Total mass = m × L × N ; Tonnes = Total mass / 1000
m = mass per metre (kg/m), L = length (m), N = quantity
Mass per metre is calculated from the gross area and a density of 7850 kg/m³. Rolling tolerances, holes, copes and weld deposits are not included.
