Description of manufacturing of Hot Dip Galvanized Gratings

1. Fully-automatic welding machine of high frequency is used to manufacture hot dip galvanized gratings and cover (except edge welding/ banding) in order to trigger any melting corrosion on the base material.

2. Material: CNS SS400 steel

3. Surface Treatment: After grating is formed, the surface is treated by hot dip galvanization; the thickness of galvanization is 610g/m².

4. Edge Welding: Two edged sides of gratings are welded with H*6 mm flat steel.
Welding slag will be removed cleanly.
