Flat Steel Weight Calculator User Guide
Flat steel is a rectangular cross-section steel widely used for grounding systems, equipment supports, guardrails, door/window reinforcement, and hardware components. Accurate weight calculation is essential for cost control and material verification.
Supported Flat Steel Types
- ✅ Material: Q235B, Q355B Carbon Steel (density 7.85 g/cm³)
- ✅ Common Sizes: Width 12mm to 200mm, Thickness 3mm to 20mm
- ✅ Calculation Modes: Single weight / Total weight with quantity
Flat Steel Weight Formula
Weight (kg) = Thickness (mm) × Width (mm) × Length (m) × 0.00785
Where:
- 0.00785 is the density coefficient (7.85 g/cm³ ÷ 1000)
