Industrial & ArchitecturalCold-Rolled Process

Flattened expanded metal

Standard expanded mesh passed through a precision cold-rolling mill to flatten raised strands into a smooth, level plane while retaining the structural diamond pattern.

Cold-rolled smooth surface

Raised strands flattened into a level plane for direct contact safety.

Finishing ready

Even surface engineered for uniform powder coating, priming, and painting.

Retained diamond mesh

Maintains standard structural rigidity, light filtration, and airflow.

Finishing & architectural uses

The completely flat profile eliminates sharp strand edges, providing a safe and tactile surface ideal for powder coating, decorative infill, and interior retail fixtures.

Typical applications
  • Partitions & room dividers
  • Sign holders & retail displays
  • Planters & outdoor enclosures
  • Cabinet infill panels
  • Architectural building facades

Mutual Metal manufactures standard flattened sheets and custom cut-to-size patterns with edge framing or custom shearing upon enquiry.

Every sheet is processed to rigorous mechanical tolerances. Review surface profiles, available alloy selections, protective coatings, and typical installation contexts below.

Surface characteristic: Flattened & smooth profile

Cold-rolled through flattening mills after expanding to produce a smooth, flat sheet with flush bond junctions. This eliminates raised diamond edges, providing a safe, touchable surface ideal for public architectural touchpoints, cabinet inserts, and laser-flat framing.
