3.The application of Coarse-Mesh grating

The products are widely used in steel structure platforms,stair treads, floors, drainages, well covers , sidewalks,decks etc. We can also design and manufacture special steel gratings on our customer's requirement.

 5.The installation of Coarse-Mesh grating

Productions made by our company are easy to install,there are two ways to install it.Weld it directly for Permanent using or  use clips to fix it for re-movement,it's very easy to install it with our special design.

6.Galvanized Coarse-Mesh grating

(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.

7.Standards of Coarse-Mesh grating

8.Tolerance of Coarse-Mesh 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.
