1. Compound steel grating is composed of checkered plate on sealed
surface & steel grating with certain spanning capability.
2. Compound steel grating is formed of any type of steel grating
and checkered plate in different thicknesses. The type
JG**3/*0/**0, JG**3/*0/**0 and JG**3/*0/**0 are generally used as
base & the checkered plate with 3mm thickness is used as
sealing plate. Sometimes checkered plate with thickness of 4mm, 5mm
or 6mm is also used as sealing plate according to customers’
requirements.
3. As thermal stress may cause shape distortion after hot-dip
galvanizing treatment, especially when choosing large spacing
grating, it’s not easy to flatten. So special attention should be
paid when choosing grating types
