Compound Steel Bar Gratings

This kind of bar gratings may deform going through the hot dipped zinc coating process. So heavy type steel bar with big gauge is normally chosen in making composite steel grid gratings.

The checkered plates covering for Compound Gratings are normally supplied in the thickness of 3mm, 4mm, 5mm or 6mm.
The Anti-Skid Checker plates can be made of Aluminum, Galvanized Steel or Stainless Steel for options at various cost.
Checkered patterns include multi bars, diamond and crocodile mouth type.

The most commonly used steel grating is G323 / 40/100 for the lower base part; common 3mm tread plate, may also be 4mm, 5mm or 6mm plate.
