|Resin selected type|
|Code||Resin type||Flame retardant performance||Standard color||Recommended use|
|V-CF||Vinyl resin||Oxygen index ≥28||Grass green, yellow, gray, orange||Acid, alkali solvent and other corrosive environment|
|V-CR||Vinyl resin||Oxygen index ≥35||Dark gray, black||High flame retardant requirements and high corrosion resistance|
|I-IF||Isophthalic resin||Oxygen index ≥28||Grass green, yellow, gray||More economical than the above two, and excellent acid resistance, moderate alkali resistance and solvent|
|I-FF||Isophthalic resin food grade||Oxygen index =26||Yellow, light grey||Mainly used in meat and food processing plants, waterworks|
|O-AF||O-benzene resign||Oxygen index ≥28||green, grey, yellow||General acid and alkali resistant environment|
|O-AN||O-benzene resign||Oxygen index <28||Grass green, yellow, gray||Compared with o-af, it is more economical, no flame retardant requirements|
|MP-5||Phenolic resign||Oxygen index <80||Brown||High fire provention requirements, low smoke environment|
|Glass fiber roving selected type|
|Code||Glass fiber roving type||Recommended use|
|E||E-glass||Used in applications with high strength requirements and high corrosion resistance|
|C||C-glass||More economical than E, but lower in strength and better acid resistance|
|Filler selected type|
|Code||Filler type||Recommended use|
|ATH||Aluminum hydroxide||Flame retardant, smoke suppression and corrosion resistance|
|CAO||Calcium carbonate||More economical than ATH, no flame retardant requirements|
|PR||No filler, pure resin||Used for high corrosion resistance|
▲ Municipal greening
The specification of GRP tree pool cover grating is generally 38*38*25mm(1.5”×1.5”×1”), and the size of the entire tree pool cover is mainly 1220*3660mm and 1220*4000mm. Different sizes of tree pools require different sizes.
▲ Trench cover for people to walk
Due to the general bearing capacity of the 25mm thick GRP grating, when applying to the trench cover, it must be noted that the inner diameter of the trench is not more than 30cm, and it is only suitable for people to walk.
▲ Factory walkway, inspection channel, floor, cargo rack
Due to good corrosion resistance of GRP grating, in some places with serious corrosion such as water treatment plants and electroplating plants, the 25mm thick GRP grating can be used as the walkway, workshop inspection channel and cargo rack.
▲ Solar photovoltaic power walkway, photovoltaic roof walkway
The photovoltaic power generation walkway generally uses the 25mm thick GRP grating. The grating has bright and long-lasting color. It is corrosion resistance, acid and alkali resistance, UV resistance and light flame retardancy.
