Bearing-bar dimension unit Bearing bar depth Bearing bar thickness Bearing bar pitch — center to center Do not enter clear opening.Panel dimension unit Panel width Panel length Number of panels Whole panels only.Material density (kg/m³) Use documented density for the actual material.Procurement allowance (%) Applied to order mass, not theoretical kg/m².Rate per kg (optional) 0 disables cost.Target mass unit Target mass (optional) Reverse-solves whole entered-size panels.Supplier finished kg/m² (optional) Reports variance without replacing theoretical bearing-bar geometry.

Calculated result

706.5 kg · 1,557.57 lb

23.55 kg/m² · 4.823 lb/ft² bearing-bar-only

33.33 bearing-bar pitches/m · 27 mm nominal clear opening

3 m² per panel · 70.65 kg theoretical bearing-bar mass/panel

706.5 kg theoretical project mass

Enter rate/kg for procurement cost

Enter target mass for reverse whole-panel count

Enter supplier finished kg/m² to compare with theory

1. Bearing-bar section = 30 × 3 = 90 mm².
2. Bearing-bar pitches per metre = 1000 ÷ 30 = 33.3333.
3. Bearing-bar mass/area = 30 × 3 × 7,850 ÷ 30 ÷ 1000 = 23.55 kg/m².
4. Panel area = 1 × 3 = 3 m²; theoretical panel mass = 70.65 kg.
5. Net project = 70.65 × 10 = 706.5 kg.

Bearing-bar-only theoretical mass. Cross bars, banding, serration, welds, cutouts, galvanizing, frames and fabrication are excluded. Use current manufacturer approved drawings/BOM for finished weight and engineering load tables for structural capacity.
