Work out how many sheets of steel reinforcing mesh (A142, A193, A252, A393) you need for a slab, allowing for overlaps.
A standard reinforcing mesh sheet in the UK is 4.8m by 2.4m, covering 11.52 m². Sheets must be lapped at the edges so the steel is continuous, which reduces the effective coverage of each sheet.
Always follow your structural engineer or building control for the correct mesh specification.
A standard UK mesh sheet is 4.8m long by 2.4m wide, giving a total area of 11.52 square metres before any overlap is allowed.
A minimum lap of around 300mm (roughly two mesh squares) is common, but always follow the structural design as heavier mesh and structural slabs may need more.
A142 or A193 mesh suits most domestic floor and shed slabs, while A252 is often specified for driveways. Your engineer or building control will confirm the right grade.
Yes. The calculator reduces the effective coverage of each sheet by the overlap you enter, then rounds up to whole sheets.
Yes, mesh is regularly cut with bolt croppers or an angle grinder to fit around edges and openings. Order whole sheets and cut on site as needed.
