Galvanized construction grating fence 25 x 5 i bar type welded steel grating
Steel Grating is made by welding with flat steel and bars with certain distances. It goes through cutting, opening, edging and other processes. The products enjoy the feature of high strength, light structure, high bearing, convenience for loading and other features. The hot dipped zinc coating gives the product excellent anti-corrosion.
Material: high quality low carbon steel or stainless steel
Types: serrated and plain
Surface process of gratings: there are three types:hot-dipped galvanized , electro-galvanized and spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.surface treatment.
Tolerance steel grating The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm. The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar. Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass the end surfaces of two sides of grating 2mm.
Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.
Hot-dip galvanizing:Good anti-rust performance,maintenance free and replacement free.
Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety,and convenient opening.
Saving investment:With large span,the cost is lower than that of cast iron when under heavy load.And the replacement expenses in case of theft and crushing will be saved.
High strength:With strength:With strength and toughness far higher than those of cast iron,it can be used in the environment with large span and heavy load,such as the wharf and the airport.
Grating Applications: Use:Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on
