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).

Advantages: saving materials, reducing investment, simple construction, durable, modern fashion, anti-fouling, reducing wind resistance, simple design, strong corrosion resistance.

APPLICATION OF STEEL GRATING:
1.  Water treatment: repair walkway, trench cover board, large container, cleaning device, blocking grate, running water tank, biochemical water treatment pool pendant, ventilation window, stairs, cooling tower operation table paving surface.
2. Chemical plant: stairway board, operating platform, guardrail, double floor, trench cover board, filter grate oil
3. Industry: offshore oil platforms
4. Textile mill: replace metal grille, wooden platform and cover cement ground, next to the dye tank, floor, near the valve, etc..
5. Power plant: chemical water workshop trench cover plate, waste pool, etc..
6. Marine food processing plant: slippery surface and other harsh environment, ships.
7. Transport: platforms, ship decks, walkways, stairs.

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.

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.
