4'x8 Fiberglass Grating 4’x8 fiberglass grating‘s advantages:

Weight aspects

Its density is only 1/4 of that of steel and 2/3 of that of aluminum. It is light and more convenient in handling and installation. For example, in the car washing room, FRP grating is used as the trench cover. The staff can move and install it with little effort, without large hoisting equipment.

Cost aspects

The raw material cost is high, and the production is complex. So, the cost is higher than that of galvanized steel grating. However, its light weight can save some transport and installation costs. This reduces the cost difference to some extent. In some large projects, FRP grating has a high procurement cost. But, its low transport and installation costs make the total cost acceptable.

Corrosion resistance aspects

It resists corrosion from acids, alkalis, solvents, salts, and gases. It has major advantages in corrosion prevention, requiring almost no maintenance. In corrosive places, like chemical plants and sewage plants, FRP grating lasts long and cuts maintenance costs.

Installation aspects

The installation is very simple, without hot work and large lifting equipment. You only need a few manual and electric tools to install it. This significantly lowers the cost and duration of installation. For example, some indoor decorations and temporary platforms show the value of fast-installing FRP grating.

For aesthetics:

The color is bright and varied. You can customize it to better blend with the surroundings and add a decorative touch. Using colored FRP for the park’s walkway and the city square can boost aesthetics.
