Expanded Metal Grating for Secure Walking
Expanded metal grating is manufactured by piercing and stretching the metal sheet in one operation creating anti-slip surface with diamond openings. The anti-slip surface offers safe foothold to stand and walk, and the openings provides free passage for unwanted materials, also gives an aesthetic appeal for design. Expanded metal grating has thicker strands than normal expanded metal sheet, which in turn affords it large load bearing characteristics.

Feature 

Diamond openings allow free passage of air, sound, heat and light. 
Superb strength to weight ratio. 
Tested load bearing capacities. 
Anti-slip properties suitable for applications where safety underfoot is critical. 
High corrosion and abrasion resistance. 
Cut to size service is available. 
Specification 

Material: stainless steel, aluminum, carbon steel, galvanized steel. 
Opening shapes: hexagon, diamond. 
Popular dimensions (cut to size service is available): 
Overall thickness: 0.2" - 0.87". 
Sheet size: 96" × 72", 96" × 48", 120" × 48". 
Open area: 48% - 77%. 
Note: when ordering expanded metal grating sheet, list the SW first, for example, 4' × 8', 6' × 8', and we also offer cut to size service.

Standard flow expanded metal grating and reverse flow expanded metal grating
There are two ways for expanded metal grating, SW is measured paralleled to the short way of the diamond opening.

Application
Expanded metal grating is the most economical way to assure strength, safety and non-skid surface, which is ideal for use on stair treads, plant runways, road crossings, wheelchair ramps, catwalks in commercial, industrial areas. And it can be cut into irregular shapes for different applications and can be installed quickly by welding.
