Steel Reinforcement Mesh Sheets – A142, A252, A393 & D49 Concrete Reinforcing Mesh, 4.8x2.4m & 3.6x2.0m, Single Sheets Delivered UK

Buy a single sheet of steel reinforcement mesh, delivered to your door — no full packs, no bundles and no trade-counter collection. Our high-tensile welded concrete reinforcement mesh — also called rebar mesh, reinforcing mesh or fabric mesh — is manufactured to BS 4483 in A142, A252, A393 and D49 designations and a choice of sheet sizes, ready for concrete slabs, foundations, paths, driveways, floor screeds and retaining walls. Order one sheet or a full stack and we deliver across mainland UK for a flat £15.

Reinforcement mesh sizes & designations

Also known as reinforcing mesh, rebar mesh or fabric mesh, each reinforcement mesh designation is defined by the cross-sectional area of steel per metre width (mm²/m). The higher the number, the more steel and the greater the load capacity:

• A142 mesh — 6mm wire, 200 × 200mm grid, ~2.22 kg/m². Light-duty a142 mesh for shed bases, paths, garden slabs and light domestic work.
• A252 mesh — 8mm wire, ~3.95 kg/m². Mid-weight a252 mesh for driveways, garages and domestic ground-floor slabs.
• A393 mesh — 10mm wire, ~6.16 kg/m². Heavy-duty a393 mesh for structural slabs, raft foundations and load-bearing work.
• D49 mesh — structural wrapping / fabric mesh for specialist reinforcement.

The full British A-series also includes A193 mesh; the designations above are our fastest-moving stock. Standard sheet sizes are 4.8m × 2.4m (11.52 m² per sheet), 3.6m × 2.0m (7.2 m²) and 2.4m × 1.2m (2.88 m²) — choose your designation and sheet size from the variant options.

What is steel reinforcement mesh used for?

Steel reinforcement mesh adds the tensile strength that concrete lacks, controlling cracking and distributing load across a slab. It is used throughout domestic, commercial and agricultural construction: ground-floor and structural slabs, strip and raft foundations, driveways and hardstandings, garage and shed bases, floor screeds, retaining walls and concrete paths. Welded at every intersection, the concrete mesh forms a rigid grid that bonds tightly with the concrete pour.

Choosing the right concrete reinforcement mesh

Match the mesh to the load. Light paths and shed bases typically use A142; driveways and domestic slabs use A252; structural and heavily loaded slabs use A393. Where a project is engineer-designed, always follow the structural drawings — the designation, concrete cover and lap length will be specified for you.

Specification

Positioning & lapping in concrete

Mesh must sit on spacers (chairs) in the lower third of the slab thickness — not on the ground — so the steel is fully encased for structural performance and corrosion protection. Overlap adjacent sheets by at least two squares (plus one bar) and tie with binding wire. Cut to size on site with bolt cutters or an angle grinder.

Delivery — single sheets to your door

Unlike merchants that sell mesh by the pack or collection-only, we deliver single sheets across mainland UK on a flat £15 charge, typically 5–8 working days. Sheets are long and heavy, so please arrange help to offload. Buying a large quantity? Contact us for a bulk price.
