Carbon Hollow Section

Weight Calculation

How is the weight of Carbon 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 Carbon Hollow Section weighs about 0.755 kg.

What is the density of Carbon?

The density of Carbon is taken as 1.7 g/cm³ (1,700 kg/m³).

Carbon Hollow Section weight table for standard sizes

Size (mm)Weight (kg/m)
20 × 20 × 20.245
30 × 30 × 20.381
40 × 40 × 30.755
50 × 50 × 30.959
60 × 40 × 30.959
100 × 100 × 53.230

How accurate is the calculated weight?

Values are theoretical; production tolerances and corner radii can make the actual weight differ by 2–5%.
