Galvanized Steel Grating

Our main products are divided into three series: steel grating series, steel grating drain cover, steel ladders, stair treads, pool cover, composite steel grating, steel grating plug, special steel grating, steel grating walkway, ceiling, the word steel grating, tooth-shaped steel grating, galvanized steel grating, painted steel grating, treads pressure lock steel grating, trench cover, composite steel grating, fiberglass grating, etc. Twisted steel; Fence; Mainly for roads, railways fence, municipal, bridge, ditch land protection, reinforcement and other buildings.

The production standard is Chinese standard GB704-88 steel, steel grid YB/T409-1998 standards of production; this standard is with the U.S.ANSI/NAAMM(MBG531-88), the same as the British BS4592-1987 standard. Products used in chemical,ports, power, paper, steel, municipal, oil, sewage treatment and other fields.

The Production of the Steel Grating:

Steel Grating is made of flat steel and bars with certain distances at high pressure resistance welding machine welded on the original plate, after cutting, incision, opening, edging and other processes customer requirements of the finished product. Features: strong Pressure welding mesh structure, high bearing, light structure, then lifting and so on. Beautiful appearance, durable; hot dip zinc coating gives very good corrosion resistance, surface gloss appearance; ventilation, lighting, cooling, explosion-proof, non-slip performance; plot against dirt.

For hot dip Galvanized Steel Grating, it can be used for longer time in different environments, the cost for hot dip galvanized steel grating is much higher than painted steel grating and black mild steel grating. When the load is not less than 5mm thick flat steel, galvanized zinc coating weight after an average of not less than 610g/m2. When the load flat steel thickness not less than 610g/m2. When the load flat steel thickness not less than 5mm, the average galvanizing zinc coating weight of not less than 460g.m2, galvanized quality and requirements should be consistent with GB/T13912-2002 requirements.

The life time of the hot dip galvanized steel grating. For the zinc layer thickness is 100μm, it can last over 100 years in dry field working environment; it can last 90 years to 100 years in the outdoor environment; it can last 50 years to 60 years in the coastal environment; it can last 40 years to 50 years in the general industry environment; it can last 30 years to 40 years in the maritime environment; it can last 20 years to 30 years in the poor environment poor marine and poor industrial environment.
