| Vinyl ester | Type V | Elevada resistência ao calor e chama ASTM E84 Class 1,25 or ltemperatura de 50℃~110℃. | Pode ser aplicada em elevada corosão quimica | 
                                        
                                            | Isophthalic Polyester | Type I | Industrial grade corrosion resistance and fire retardant,flame   spread rating ASTM E84 Class 1,25 or less,operation   temperature-50℃~105℃. | Such gratings can be used in the environments of middle   concentration inorganic acid,inorganic alkali,etc. | 
                                        
                                            | Food grade polyester resin | Type F | Fodd grade corrosion resistance and fire retardant,operation   temperature-50℃~105℃. | Such gratings are often used in food plants or drinking water   plants. | 
                                        
                                            | Orthophthalic polyester resin | Type O | Moderate corrosion resistance and fire retanrdant,flame spread   rating ASTM E84 Class 1,25 or less,operation temperature50℃-100℃. | Such gratings are perfect for use in water/wastewater or air-aging application,light industrial applications,and in the wavezone areas of   offshore platforms where the environment is moderate.Although Type O is the   least chemical resistant resin,it still offers superior performance to   traditional flooring products such as steel,aluminum and wood,and is the most   economical resin available. | 
                                        
                                            | Phenolic resin | Type P | Low smoke and superior fire resistance,flame spread rating ASTM E84 Class 1,5 or less,smoke developed index o,operation temperature amounting to 180℃. | Such gratings are usded in areas where fire resistance,low   smoke,and low toxic fumes are critical. |
