Products Description
Steel graing can be made by Manual welding,Machine welding,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.Cross bar is pressed into the beaing bar by high tension resistance welding which is controlled by mould/computer
Flat steel is generally cold rolled Q235 flat steel, can also be hot rolled I flat steel, tooth flat steel, inclined flat steel, stainless steel flat steel and other specifications.The bar is generally twisted square steel, square steel, round steel, flat steel, etc.The surface treatment has: hot galvanizing, cold galvanizing, spray model, spray paint, dip anti-rust oil can prevent oxidation rust, (general stainless steel need not above treatment, most stainless steel surface polishing treatment).

Inspection
After the production,the inspector will do the inspection.
We check the height, thickness of the flat bar, the pitch of the flat bar and twist bar.
The size of the grating panel,the width,length and the diagonal,also checking if the welding is well enough.
APPLICATION OF STEEL GRATING:
1. Power plant: chemical water workshop trench cover plate, waste pool, etc..
2. Marine food processing plant: slippery surface and other harsh environment, ships.
3. Transport: platforms, ship decks, walkways, stairs.
4. Beverage industry: Staircase floor board, replacement of expensive stainless steel, loaded floor.
Packaging and Shipping
The grating usually packing in pallent, with steel belt to fix, the surface of steel grating with plastic film to escape of damp.
Special requirement of the packing can be customized.
