Introduction

Expanded metal diamond mesh is produced from a single metal sheet that is simultaneously slit and stretched to form a continuous mesh with diamond-shaped openings. The diamond pattern is the most widely used geometry because it absorbs energy effectively and resists mechanical deformation after installation. Unlike woven wire mesh, the strands remain integral to the original sheet, with no joints or weak points.

The diamond metal mesh can be made of various materials, such as stainless steel, carbon steel, galvanized steel, aluminum, copper and brass, etc. The stainless steel diamond metal mesh is the most durable with strong corrosion and rust resistance. Carbon steel can be galvanized to improve its corrosion resistance.

Diamond Metal Mesh characteristics

High strength: The diamond-shaped opening gives it better strength and rigidity.

Slip resistance (raised type): Standard raised diamond mesh has angled strands that provide grip for walkways and platforms.

Formability: Can be bent up to 90° for customized shapes and applications.

Environmental protection:No waste of materials in the production process, less raw material input, and higher product output.

Diamond Metal Mesh application

Fencing & security: Fence infill, partitions, machine guards, window security panels.

Walkways & platforms: Catwalks, stair treads, ramps, drainage covers — utilizing the raised diamond texture for slip resistance.

Architecture & construction: Suspended ceilings, façade cladding, Wall cladding,balustrade infill, sunshades, plaster lath.

Industrial & filtration: Ventilation grilles, filters, screening, equipment enclosures.

Automotive & engineering: Machinery guards, decorative trim, and general fabrication.
