What is B785 mesh used for? B785 is one of the heaviest structural fabrics Next Day Steel stocks. Its 10mm main wires are packed at 100mm centres for 785mm² of steel per metre, more than double a B385 sheet, with 8mm cross wires at 200mm. To BS 4483, it is the fabric of choice for the most heavily loaded one-way slabs, letting designers reinforce demanding floors without resorting to loose-bar detailing. Full specifications and a grade-by-grade comparison appear further down this page.
Typical applications
- Heavily loaded one-way suspended slabs
- Transfer slabs and long-span floors
- Industrial structures and high-load decks
- Schemes demanding maximum mesh capacity

B785 mesh: frequently asked questions
What is B785 mesh used for?
B785 reinforcement mesh is used for heavy industrial slabs and ground beams. It helps concrete resist tensile and load-bending forces so slabs are less likely to crack.
What size sheets does B785 mesh come in?
B785 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 B785 mesh manufactured to?
Our B785 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 B785 mesh cost?
B785 mesh starts from £42.98 + 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 785 in B785 stand for?
The number is the cross-sectional area of steel in square millimetres per metre width: B785 carries 785 mm² of steel per metre in each direction. The higher the number, the more steel in the sheet and the stronger the reinforcement.
