Factory making Gully Grating Covers - Compound Steel Grating – JIULONG Detail:

Compound Steel Grating
1. Compund steel grating is composed of chequered plate on sealed surface & steel grating with certain spanning capability.
2. Compound steel grating is formed of any type of steel grating and chequered plate in different thicknesses. The grating of JG323/40/100, JG253/30/100 or JG323/60/100 is generally 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.
3. As thermal stress may produce shape distortion for compound steel grating after hot-dip galvaning treatment, especially when choosing large spacing grating, it’s not easy to make it smooth. So attention should be paid when choosing grating types.
