alpolene Hollow Section

Weight Calculation

How is the weight of alpolene Hollow Section calculated?

Hollow section weight is the outer cross-section minus the hollow core: (height × width − (height − 2 × wall) × (width − 2 × wall)) × length × density. One metre of 40 × 40 × 3 mm alpolene Hollow Section weighs about 0.426 kg.

What is the density of alpolene?

The density of alpolene is taken as 0.96 g/cm³ (960 kg/m³).

alpolene Hollow Section weight table for standard sizes

Size (mm)Weight (kg/m)
20 × 20 × 20.138
30 × 30 × 20.215
40 × 40 × 30.426
50 × 50 × 30.541
60 × 40 × 30.541
