Square Steel Weight Calculator User Guide
Square steel has a square cross-section, available as hot-rolled solid bars or cold-drawn precision bars. Widely used for machinery supports, building structures, door/window frames, handrails, and mold manufacturing.
Supported Square Steel Types
- ✅ Materials:
- Carbon Steel (density 7.85 g/cm³)
- Stainless Steel (density 7.93 g/cm³)
- Aluminum (density 2.70 g/cm³)
- Copper (density 8.90 g/cm³)
- ✅ Common Sizes: Side length 10mm to 200mm
- ✅ Calculation Modes: Single weight / Total weight with quantity
Square Steel Weight Formula
Weight (kg) = Side Length² (mm) × Length (m) × Density Coefficient
Density coefficients by material:
- Carbon Steel: 0.00785
- Stainless Steel: 0.00793
- Aluminum: 0.00270
- Copper: 0.00890
