Expanded metal is formed from a single sheet of metal. The expansion process does not involve any interweaving, interslotting, blazing or welding. Hence, the expanded metal comes supplied as a single jointless continuous sheet, retaining all the inherent strength of metal plus the many derived advantages from the process. 
WeiCai expanded metal meshes are manufactured for various high performance industrial applications. It is highly flexible and can be fabricated in various shapes and sizes, and retains its strong and durable characteristics. 

Application: 
Walkway, stairtreads and platforms
Window guards / grilles
Wall reinforcement
Perimeter fencing / gates
Top-of-wall spikes
Pedestrian safety barriers
Motorway anti-glare screens
Security room partitions / panels
Screens
Security cages
Storage shelves / trays
Machinery safety guards
Security vehicle window guards
Balustrades
And many various uses

Advantage: 
Cutting to shape is the only fabrication. Even when cut into irregular shapes and left unframed the mesh does not fray. 
Very efficient conductor. 
The uncut knuckles support weight and withstand stress better than joints of welds. 
Higher strength-to-weight ratio than the original sheet material. 
Allows free passage to light, heat, sound and air. 
Screening effect. 
Makes an excellent reinforcement material. 
Provides anti-slip surface. 
The consistent diamond-pattern looks attractive.
