Welded Mesh Area and Weight Chart (Ø4 to Ø12)
Welded mesh chart for Ø4 to Ø12 wire at 50 to 300 mm spacing: area in cm²/m in one direction and weight in kg/m² of square mesh. Exact relations, labelled drawing.
For preliminary quantities and comparison. Strength, minimum reinforcement, laps and manufacturing tolerances are not checked. A qualified engineer must complete the final design to the applicable standard.

Conditions and notes
Round wire, nominal diameter. Steel density 7850 kg/m³. Square mesh with the same diameter and spacing in both directions. Edge overhang and laps excluded.
- If the two directions have different diameters or spacings, compute each direction and add them: m = (as1 + as2) × 7850.
- The diameters and spacings in the grid are for convenience, not a list of standard products.
- For the mass of a mesh sheet, the welded mesh weight calculator also includes edge overhangs.
The area in one direction is as = (π d²/4) / s. For Ø8 at s = 150 mm it is 50.27 mm² / 0.15 m = 335.1 mm²/m, which is 3.35 cm²/m.
The theoretical mass of a square mesh is the sum of wires in both directions: m = 2 × as × 7850 kg/m³. For Ø8 at 150 mm it is 2 × 0.0003351 × 7850 = 5.26 kg/m². Edge overhangs, laps and weld points are not included.
The grid is generated from the relations. Standard mesh type names and market availability are not part of this table.
