Expanded Metal Mesh
Expanded metal mesh is produced by slitting a sheet of metal and then stretching it into an open lattice of diamond‑shaped openings. Because no material is lost in the process, expanded mesh retains the strength of the original sheet while becoming lighter and more flexible. Stainless steel expanded mesh offers corrosion resistance and an attractive appearance.
Benefits & Features
- No welds: The continuous strands formed during expansion create a single‑piece structure without joints or welds.
- Lightweight yet strong: Mesh provides excellent strength‑to‑weight ratio, making it suitable for walkways and safety grating.
- Variety of patterns: Choose from standard (raised) diamonds or flattened patterns; select small, medium or large opening sizes.
- Decorative appeal: The diamond motif adds visual interest to architectural facades, partitions and sunscreens.
Applications
Expanded stainless mesh is versatile and appears in a variety of settings:
- Architectural façades: Provide shade, ventilation and aesthetic value on building exteriors.
- Safety grating: Install as stair treads, catwalks and platform flooring with excellent slip resistance.
- Filtration & separation: Use as a support layer in filters and screens requiring high flow and strength.
- Decorative panels: Create partitions, ceiling panels and wall art with an industrial look.
