Compound Steel Bar Gratings

Product description

1. Compound Steel Bar Gratings Introduction
Compound steel grating is a product made of steel grating with certain crossing and checkered plate with seal

surface in different thicknesses. The grating type G323/40/100, G253/30/100 and G323/60/100 are generally

used as base support materials. The checkered plate galvanized or hot dipped with 3mm thickness is used as surface plate.

Checkered plate is used as riffled plates with thickness of 4mm, 5mm or 6mm according to customer's requirements.

Compound steel grating will generate buckling deformation due to thermal stress after hot dip galvanizing, and larger steel grating has difficult levelling, so please note type selection.
