Reinforcing Welded Mesh for Concrete Reinforcement

Two Shapes of Reinforcing Welded Meshes

Reinforcing welded mesh, manufactured from 500MPa wire grade L, is usually used for concrete reinforcing. As concrete is weak in tension, applications of reinforcing welded mesh minimize the cracking on the surface of concrete in construction. Deformed or plain bars are welded in longitudinal and transverse directions to form different shapes of apertures, which mainly form square reinforcing mesh and rectangular reinforcing mesh. For square welded mesh, longitudinal and transverse wires support the whole strength at the same time, while for rectangular welded mesh, longitudinal wire is the supporting one.

Advantages

• Reinforcing welded mesh is manufactured in sheets and rolls, which makes the installation process quick and simple, and it saves time and binding wires.
• Its ribbed profile improves bonding to concrete elements, improving stress distribution, crack resistance, and strengthening stability of the construction.
• The reinforcing mesh can be designed according to the project requirement, which reduce the material and labor cost and improve the efficiency of the whole construction.
• It has great corrosion resistance and oxidation resistance.

Material and surface treatment
Low-carbon iron wire, steel bar, rebar wire, stainless steel wire, galvanized iron wire (electronic galvanized, hot-dipped galvanized), black iron wire, etc.

Specification

• The standard sizes for square and rectangular sheets and rolls are:
  • Sheets: 6m (length) × 2.4m (width) =14.4m².
  • Rolls: 60m (length) × 2.4m=144m².
• Wire diameter: 4mm to 40mm.
