Product Detail

Product Tags

Hard drawn mesh provides

High yield strength (≥ 485 MPa) for crack-resistant concrete structures

High tensile strength (775–855 MPa) for both short-term impact and long-term load stability

Lightweight design to facilitate transportation and installation

Strong weld points (shear strength ≥ 250 N/mm²) to maintain mesh integrity during handling and concrete pouring

With these features, Hard Drawn Mesh not only shortens construction cycles and reduces labor costs but also enhances the durability and safety of concrete structures.
