A393 Mesh - Steel Reinforcement - 10mm Cross Bar
Alternative Names: A393 Reinforcing Mesh, A393 Steel Mesh, A393 Concrete Mesh, Reinforcement Mesh, Steel Reinforcement Mesh, Concrete Reinforcement Mesh, 10mm Rebar Mesh, Steel Fabric Mesh, Reinforcing Fabric, Mesh Fabric, Reinforcing Matting, Steel Matting, Structural Mesh, SL Mesh, ECO Mesh, Merchant Mesh, Flying End Mesh, Slab Mesh, Foundation Mesh, Ground Beam Mesh, BS4449 Mesh, CARES Approved Mesh
What is A393 mesh used for? A393 is the heaviest-gauge square reinforcing fabric in the BS 4483 range. Built from 10mm Grade B500 wires welded at 200mm centres in both directions, it provides equal strength each way, making it the standard choice wherever a slab needs robust two-way reinforcement from a single sheet. Because the bars match in diameter and spacing, A393 behaves the same in both directions, which keeps design simple for square or near-square bays. Full specifications, sheet weights and a grade-by-grade comparison appear further down this page.
Typical applications
- Heavy-duty ground-bearing slabs and structural rafts
- Industrial, warehouse and yard floors
- Suspended slabs requiring two-way reinforcement
- Structural toppings under heavy loading

A393 mesh: frequently asked questions
What is A393 mesh used for?
A393 reinforcement mesh is used for heavy-duty slabs, car parks, rafts and ground-bearing floors. It helps concrete resist tensile and load-bending forces so slabs are less likely to crack.
What size sheets does A393 mesh come in?
A393 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 A393 mesh manufactured to?
Our A393 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 A393 mesh cost?
A393 mesh starts from £33.50 + 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 393 in A393 stand for?
The number is the cross-sectional area of steel in square millimetres per metre width: A393 carries 393 mm² of steel per metre in each direction. The higher the number, the more steel in the sheet and the stronger the reinforcement.
