Steel Expanded Metal

Expanded metal mesh (also known as steel plate mesh, metal expansion mesh, or stretched mesh) is a mesh product made from metal sheets through a single stamping, slitting, and stretching process, forming diamond-shaped or other openings. The mesh has no welds—the strands and bonds are integral to the original sheet, creating a continuous structure.

Expanded metal mainly includes standard (raised) type, flattened type, heavy-duty grating, decorative type, and micro mesh. The raised type retains the three-dimensional angle from stretching and offers slip resistance; the flattened type is cold-rolled for a smooth, flat surface.

• One-piece construction, no welds: Formed from a single sheet, with strands and bonds as an integral structure for superior integrity.

• High strength-to-weight ratio: The stretching process expands the material area while reducing weight, maintaining high rigidity.

• High material utilization: Openings are created by slitting and stretching rather than punching and removing material, minimizing waste.

• Good permeability: Open openings allow air and light to pass through, combining protection with ventilation.

Expanded metal is used across construction, industry, transportation, and decoration: plaster reinforcement, machine guards, highway guardrails, and stadium fencing; heavy-duty mesh for tanker foot mesh, working platforms, and stair treads; also used as concrete reinforcement, speaker grilles, and filter elements.
