Galvanized steel Grating, is extremely strong and durable for all load bearingapplications and is primarily used for pedestrian and light vehicle traffic. Ourgalvanized coating process provides for years of corrosion resistance in acidicand high moisture environments.
Galvanized steel Expanded Metal is a sheet product that has been slit andstretched to diamond shaped openings. Galvanized expanded metal offerssavings in weight and allows free passage of light, liquid, sound and air whileproviding corrosion resistance in harsh environments.
According to the different types of flat steel, the steel grillageismainly divided into the following three types,comparison of feature.
1.Plain Type
One of the most widely used grating.Availablefor flooring, sidewalk, drainage pit cover, stairtread, etc.
2.Serrated Type
Better non-skid property & safety comparingto plain grating.
3.l Bar Type
Lighter, more economical and paraticacomparing to plain grating.
