Expanded metal grating for safety and anti-slipping purpose is equal to raised expanded metal mesh, which has better slip resistant performance than flattened metal mesh. On the other side, expanded metal grating without welding surface is more durable and solider when compared with welded wire mesh. Its surface has many hole patterns for versatile application, including diamond holes, hexagonal holes, oval holes and other decorative holes. In order to add additional security, corrosion resistance and rust resistance, generally expanded metal sheet is made of carbon steel sheet, stainless steel or aluminum with galvanized and PVC coated. Now, expanded metal grating has been used in many areas, such as stair treads, ramp, flooring, walkway, platform, and industrial sites.
