FRP grating is a raw material made of resin, while hot-dip galvanized steel grating is a raw material made of carbon steel. Hot-dip galvanized steel grating has a longer service life than FRP grating, and the surface of hot-dip galvanized steel grating is general. They are all hot-dip galvanized and have better corrosion resistance.
Since the FRP grating is composited by resin and glass fiber, its density is less than 2 kg per cubic decimeter, which is only 1/4 of carbon steel. Hot-dip galvanized steel grating has more load-bearing capacity, like some requirements For special load-bearing places, hot-dip galvanized steel gratings should be used instead of FRP gratings.
Hot-dip galvanized steel grating is a steel grating product that has been processed by hot-dip galvanizing. There is only one color, silver white, while the glass fiber reinforced plastic grating can meet the color requirements of customers. The colors are yellow, black, gray, green, blue, and red.
Hot-dip galvanized steel grating is more corrosion-resistant than FRP grating. The excellent electrical insulation of FRP grating is a feature that hot-dip galvanized steel grating does not have. As the FRP grating is relatively light in weight, flexible in size, and convenient to cut, it does not require motor vehicles and large lifting equipment, and only requires a small amount of labor and electric tools, which greatly reduces the installation cost.
