What is B283 mesh used for? B283 is the lightest structural (B-type) fabric in the BS 4483 range. Its 6mm main wires sit at close 100mm centres with 7mm cross wires at 200mm, concentrating steel in the principal spanning direction, which is the defining feature of structural mesh. Where a slab spans predominantly one way, this layup is more efficient than square mesh because the steel is placed where the bending is greatest. Full specifications and a grade-by-grade comparison appear further down this page.
Typical applications
- One-way ground and suspended floor slabs
- Lightly loaded structural slabs
- Garage and outbuilding floors
- Walls and panels where steel is needed mainly one way
- Projects upgrading from square mesh to structural fabric
Why buy from Next Day Steel
B283 sheets are stocked for next-day delivery and arrive CARES approved with mill certificates. As the entry point to the B-series, it is a cost-effective upgrade from square mesh whenever one-way spanning governs. Browse the full structural mesh range to compare gauges, or add spacers to set your cover.

B283 mesh: frequently asked questions
What is B283 mesh used for?
B283 reinforcement mesh is used for one-way spanning slabs and lightly loaded suspended floors. It helps concrete resist tensile and load-bending forces so slabs are less likely to crack.
What size sheets does B283 mesh come in?
B283 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 B283 mesh manufactured to?
Our B283 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 B283 mesh cost?
B283 mesh starts from £99.28 + 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 283 in B283 stand for?
The number is the cross-sectional area of steel in square millimetres per metre width: B283 carries 283 mm² of steel per metre in each direction. The higher the number, the more steel in the sheet and the stronger the reinforcement.
