galvanized steel grid features
(1)Attractive appearance:Simple outline.silver colour,and modern.
(2)Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.
(3)Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free.
(4)Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety,and convenient opening.
(5)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.
(6)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.
(7)Many specifications available: The requirement of different environments,loads,spans,sizes and shapes can be satisfied.
Standards of serrated galvanized steel grating.

application of galvanized steel grid
The products are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers etc. We can design and manufacture standard galvanized steel grid and in customer's requirement.
Tolerance of hot dip galvanized 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.
The package of galvanized steel grid
galvanized steel grid is normally packed in the way with two pieces of square wood on both upper and bottom sides.there are four or six pieces M10 long bolt penetrating the grids and screwing them together.it is suitable for loading and unloading by forklift.But we also packing our products on costumer’s requirement.
