Zinc Hollow Section
Weight Calculation
How is the weight of Zinc 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 Zinc Hollow Section weighs about 3.152 kg.
What is the density of Zinc?
The density of Zinc is taken as 7.1 g/cm³ (7,100 kg/m³).
