Mesh dimension unit SWD — short-way diamond pitch Center-to-center short-way pitch.Strand width Strand / base-metal thickness Sheet dimension unit Sheet width Sheet length Number of sheets Whole sheets only.Material density (kg/m³) Use documented density for the actual alloy/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 sheets.Supplier kg/m² (optional) Reports variance without replacing theoretical geometry.

Calculated result

54.26 kg · 119.62 lb

1.884 kg/m² · 0.3859 lb/ft²

88% approximate open area · 12% theoretical metal fraction

2.88 m² per sheet · 5.426 kg per sheet

54.26 kg net batch mass

Enter rate/kg for procurement cost

Enter target mass for reverse whole-sheet count

Enter supplier kg/m² to compare against geometry

1. Theoretical metal fraction ≈ 2 × 3 ÷ 50 = 0.12.
2. Mass/area = 0.12 × 2 mm × 7,850 kg/m³ ÷ 1000 = 1.884 kg/m².
3. Sheet area = 1.2 × 2.4 = 2.88 m²; sheet mass = 1.884 × 2.88 = 5.426 kg.
4. Net batch = 5.426 × 10 = 54.259 kg.

Theoretical expanded-metal strand estimate only. Raised/flattened geometry, bonds, coatings and manufacturing tolerances are not modeled. For named mesh or grating styles, use current manufacturer nominal weight/certification; do not use this tool for structural load capacity.
