Expanded Metal
Expanded Metal
Our Expanded Metal sheets represent the peak of material efficiency and structural rigidity. By slitting and stretching high-grade steel, stainless steel, or aluminum sheets in a continuous cold-forming process, we create a unified, jointless mesh. The resulting diamond-shaped strands are set at an angle that optimizes tensile shear and load distribution ratios, providing superb weight savings and multi-directional structural strength.
Key Features
Jointless, cold-expanded diamond geometry for maximum structural stiffness
Optimized tensile shear and load distribution ratios under heavy loads
Available with hot-dip galvanizing, electrostatic powder coatings, and PVDF finishes
Mill test certifications and raw material heat codes provided
Common Applications
Heavy-duty industrial walkways, ramps, and stair treadsHigh-security perimeter fencing and military installationsArchitectural solar shading, facade cladding, and balustradesDefense armored vehicle protective grilles and machine guards
