Different Types of FRP molded grating and applications

According to the irregular classification series of FRP grating often used, the FRP grating series can be roughly divided into the following categories：

I. FRP grating cover

The so-called non-slip performance can be better reflected in the FRP grating cover, such as gritted cover grating, chequre plate cover grating etc.

The surface of FRP grating cover can be smooth surface, non-slip gritted surface or non-slip chequre surface, the thickness of grating cover is generally 4.0mm, also can be produced according to customer's size, the cover grating is often used in areas requiring confinement, used in sewage treatment facilities, which can prevent corrosion and gas spillage, the cover grating with non-slip surface can also be used as ramp, manhole cover, trench cover.

2. Conductive FRP grating

FRP grating itself belongs to the insulator, not conductive, not thermal conductivity, but in some specific occasions, the FRP grating also has the requirements of conductivity. The specific method of operation is to add a graphite layer with a thickness of about 3~5mm on its surface to eliminate the danger of static charge generation. Conductive grating also has the same characteristics as traditional FRP grating, such as corrosion resistance, flame retardant, impact resistance, anti-slip, light weight, etc. It is suitable for oil refineries, arms manufacturing plants, high-tech industries, computer rooms, chemical fiber plants, dry areas and underground mineral mining operations, etc.

3. Micromesh FRP grating
Micromesh FRP grating is designed for lower cost and corrosion resistance than aluminum grating and steel grating. The double layer of micromesh grating can prevent small tools and other items from falling off the grating surface. Micromesh grating meets the 15mm diameter ball test and is suitable for gutter covers, coastal platforms, semiconductor and communication areas, and computer rooms.

4. Flat FRP cover plate
Flat FRP cover is made of fiberglass fiber, fiberglass short-cut felt and resin cured by hand gluing. The surface of flat FRP cover can be smooth, non-slip gritting surface and non-slip checker surface. Generally, the flat FRP cover is used in combination with FRP grating, which is also called FRP cover.
