Compound steel grating?is composed of plate on sealed surface & steel grating with certain spanning capability.
Compound steel grating is formed of any type of steel grating and chequered plate in different thickness. The grating of JG323/40/100, JG253/30/100 or JG323/60/100 is widely used as support plate & the chequered plate with 3mm thickness is used as upper plate, while the plate of 4mm, 5mm or 6mm thickness may also be used based on customers’?requirements.
As thermal stress may produce shape distortion for compound steel grating after hot-dip galvanizing treatment, especially when choosing heavy duty grating, it’s not easy to flatten. So attention should be paid when choosing grating types.
Compound steel grating is widely used in the platform, bridge, well cover,power plant, petro-chemistry, sewage treatment and so on.
