B785 Mesh

B785 mesh is a welded reinforcement fabric used in concrete projects where more reinforcement is required in one direction than the other. South Steel supplies B785 mesh online for homeowners, self-builders, contractors and trade buyers.

Check that B785 is the mesh grade shown on your drawings, calculations or reinforcement schedule before ordering.

What to Check Before Ordering B785 Mesh

Use the information provided by your engineer to confirm the grade and quantity required. Review the sheet dimensions and delivery information before ordering.

South Steel can help clarify product details. For larger orders, drawings or reinforcement schedules can be submitted for quotation.

For load-bearing concrete work, follow the project documents for mesh orientation, overlap, positioning and concrete cover.

B785 Mesh Specification Explained

B785 is a rectangular reinforcement mesh, meaning the amount of steel differs between its two directions.

Its nominal specification is:

• Main wire diameter: 10mm
• Main wire spacing: 100mm centres
• Main steel area: 785mm² per metre
• Cross wire diameter: 8mm
• Cross wire spacing: 200mm centres
• Cross steel area: 252mm² per metre
• Nominal mass: 8.14kg per m²

The “785” refers to the nominal cross-sectional area of steel provided per metre in the main direction. It does not refer to the sheet size.

Because wire diameter and spacing differ in each direction, the mesh should match the orientation shown in the project design. A similar-looking sheet should not be treated as an automatic substitute.

Where B785 Mesh May Be Specified

B785 reinforcement mesh may be specified for reinforced concrete slabs, floors, walls and other elements. Its suitability depends on the reinforcement requirements in the project design.

Use the mesh reference stated in the project documents rather than selecting a grade based only on general application.
