Note: Calculate the theoretical weight calculation formula of commonly used profiles:
m=F×L×Ï
M—mass Kg; F—section area m2; L—length m; Ï—density*Kg/m3
☆ Among them: F area calculation method:
1. Fang Gang F= a2
2. Steel pipe F = 3.1416 × $ (D-$) D - diameter $ - thickness
3, steel plate, flat steel F = a × $ a - width
density:
Steel: 7.85*103 kg/m3
Aluminum: 2.5 to 2.95*103
Copper: 8.45-8.9*103
Cast iron: 6.6~7*103
Nylon: 1.04 to 1.15*103
