B385 Mesh

B385 mesh is a welded steel reinforcement fabric with 7mm wires in both directions at different spacing. This creates a greater steel area in the main direction. South Steel supplies B385 mesh online for homeowners, self-builders, contractors and trade buyers.

If B385 is listed on your drawings or reinforcement schedule, use that specification when ordering.

Understanding B385 Mesh Before You Order

The main wires are spaced more closely than the cross wires. This gives B385 its directional reinforcement pattern, even though both sets of wires are 7mm in diameter.

Before ordering, check the grade, dimensions and quantity against your project information. South Steel can clarify product details and support larger quotations.

For structural concrete work, mesh orientation, overlap, positioning and concrete cover should follow the engineer’s drawings.

B385 Mesh Specification at a Glance

The nominal specification is:

• Main wire diameter: 7mm
• Main wire spacing: 100mm centres
• Main steel area: 385mm² per metre
• Cross wire diameter: 7mm
• Cross wire spacing: 200mm centres
• Cross steel area: 193mm² per metre
• Nominal mass: 4.53kg per m²

The “385” refers to the nominal cross-sectional area of steel provided per metre in the main direction. It does not refer to the wire diameter or sheet dimensions.

Because the main wires are placed at half the spacing of the cross wires, the mesh provides more steel in that direction. This makes the orientation shown in the project documents important.

Where B385 Reinforcement Mesh May Be Specified

B385 reinforcement mesh may be specified for concrete slabs, floors, walls and other structural elements requiring greater reinforcement in one direction.

It is often identified on drawings or reinforcement schedules, so match the product reference rather than selecting mesh based only on appearance or wire diameter.
