What is A142 mesh used for? A142 is the lightest and most widely used square reinforcing fabric in the BS 4483 range, and the default choice for everyday domestic concrete. Built from 6mm Grade B500 wires welded at 200mm centres in both directions, it provides equal, modest reinforcement each way: ideal for controlling cracking and adding strength to ground-bearing slabs that are not carrying heavy structural loads. Light enough to position and cut by hand, it is the go-to mesh for driveways, paths and garage bases. Full specifications, sheet weights and a grade-by-grade comparison appear further down this page.
Typical applications
- Domestic ground-bearing floor slabs
- Driveways, paths and patios
- Garage, shed and outbuilding bases
- Screeds and light foundations
- Crack control in non-structural slabs

A142 mesh: frequently asked questions
What is A142 mesh used for?
A142 reinforcement mesh is used for shed bases, footpaths, patios and light domestic slabs. It helps concrete resist tensile and load-bending forces so slabs are less likely to crack.
What size sheets does A142 mesh come in?
A142 is stocked in the sheet sizes shown above (2.4m x 1.2m (safety), 3.6m x 2m, 4.8m x 2.4m), and can be cut to size. The 4.8m x 2.4m sheet covers 11.52m² and the 3.6m x 2m sheet covers 7.2m².
What standard is A142 mesh manufactured to?
Our A142 mesh is welded steel fabric manufactured to BS 4483 from Grade B500 wire (BS 4449:2005), CARES approved with full mill traceability. (Reinforcement is certified through the CARES scheme rather than CE marking, as EN 10080 is not a harmonised standard.)
What size mesh do I need for a driveway or slab?
As a guide: A142 suits shed bases and paths, A193/A252 suit domestic driveways, and A393 is used for heavy-duty slabs, car parks and rafts. Always follow your structural engineer's specification where one is provided.
How much does A142 mesh cost?
A142 mesh starts from £16.89 + VAT for the smallest sheet size, and every current sheet price is shown in the size panel above. Bulk-buy discounts apply automatically as weight is added to the cart.
What does the 142 in A142 stand for?
The number is the cross-sectional area of steel in square millimetres per metre width: A142 carries 142 mm² of steel per metre in each direction. The higher the number, the more steel in the sheet and the stronger the reinforcement.
