B385 Mesh - Steel Reinforcement - 7mm Cross Bar
Alternative Names: B385 Reinforcing Mesh, B385 Steel Mesh, B385 Concrete Mesh, B Mesh, Reinforcement Mesh, Steel Reinforcement Mesh, Concrete Reinforcement Mesh, 7mm Rebar Mesh, Steel Fabric Mesh, Reinforcing Fabric, Mesh Fabric, Reinforcing Matting, Steel Matting, Structural Mesh, Rectangular Mesh, Long Mesh, ECO Mesh, Merchant Mesh, Flying End Mesh, Slab Mesh, Suspended Slab Mesh, BS4449 Mesh, CARES Approved Mesh
What is B385 mesh used for? B385 structural mesh steps the main wire up to 7mm at 100mm centres, giving 385mm² of steel per metre in the principal direction, tied to 7mm cross wires at 200mm. It is a popular mid-range structural fabric for one-way spanning slabs to BS 4483. The matched 7mm wires produce a balanced sheet that is easy to handle yet noticeably stronger than the lightest structural grades. Full specifications and a grade-by-grade comparison appear further down this page.
Typical applications
- One-way suspended and ground-bearing slabs
- Structural floors carrying moderate loads
- Suspended garage and ground floors
- Walls and retaining panels
- General structural reinforcement where one-direction capacity governs

B385 mesh: frequently asked questions
What is B385 mesh used for?
B385 reinforcement mesh is used for one-way spanning suspended slabs. It helps concrete resist tensile and load-bending forces so slabs are less likely to crack.
What size sheets does B385 mesh come in?
B385 is stocked in the sheet sizes shown above (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 B385 mesh manufactured to?
Our B385 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 B385 mesh cost?
B385 mesh starts from £104.90 + 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 385 in B385 stand for?
The number is the cross-sectional area of steel in square millimetres per metre width: B385 carries 385 mm² of steel per metre in each direction. The higher the number, the more steel in the sheet and the stronger the reinforcement.
