Expanded Metal Grating
Expanded metal grating is the most practical and economical way to assure strength, safety, and a non-skid surface. Expanded metal grating is ideal for use on plant runways, working platforms, and catwalks, as it is easily cut into irregular shapes and can be installed quickly by welding or bolting.
Materials:
Expanded Metal Grating is a heavy duty expanded metal, produced from carbon steel, aluminum, or stainless steel plate. Expanded Metal Grating contains no joints or welds, each sheet is a single piece of sturdy steel.
Applications:
Expanded Metal Grating is the most popular of all grating types due to its strength, cost-efficient production and ease of installation. Universally used in most general industrial plants as well as commercial buildings, it has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.
Advantages:
Expanded wire mesh grating is available in a variety of thicknesses with differing sizes and designs of the apertures.
The high strength to weight makes expanded metal grating suitable for many industrial and ornamental applications.
A further feature is the provision of an excellent anti-slip surface. This makes the product suitable for ramps (e.g. inclined walkways adjacent to conveyors) platforms and stair treads.
