Mild Steel Platform Steel Grating Hot Dipped Galvanized Bar Grating 25mm X 5mm
Mild Steel Platform Steel Grating Hot Dipped Galvanized Bar Grating 25mm X 5mm
Steel Grating /grate floor made by welding with flat steel and cross/round bars with certain distances. Our Steel Grating enjoy the feature of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product excellent anti-corrosion.
Grating is the workhorse of the industrial flooring market and has served industry for decades.Strong and durable with an exceptional strength-to-weight ratio, metal bar grating can be easily fabricated to nearly any configuration. The high percentage of open area makes bar grating nearly maintenance free and all products are fully recyclable.
