Standard Expanded Metal
LWM: 3.0mm-150mm
SWM: 2.0mm-80mm
Strand Thickness: 0.3mm to 8.0mm
Strand Widht: 0.3mm-8.0mm
Packing: In plastic film, in wood pallet
Materials: Steel plate, aluminum plate, stainless steel plate, titanium plate, alum-platinum plate, lead plate, nickel plate, etc.
Features:
Standard expanded metal has a wide range of uses, graceful shapes, and strong processing capability. A major advantage of expanded metal mesh is that the mesh is formed from a single piece of material so the process is not wasteful and therefore cost effective.
Standard expanded metal still has many other features, such as lightweight, economical, slip-resistant surface, low maintenance, can be bent or formed in any direction and U-edging for finished edges.
Applications:
Air and fluid filters
Emi/rfi shielding
Battery cells
Greenhouse benches
Containers
Walkways and stair treads
Concrete reinforcement
Satellite and radar antennas
Outdoor furniture
Speaker grills
Fencing
Ventilation systems
Machine and window guards
Partitions
Strainers
Decorative dividers
Security walls, ceilings, floors, doors
