The products can resist corrosion from various gas or liquid medium suchas acid, alkali, organic solvent and compound. According to the requirementof deferent environment, customers have options in using orthophthalicpolyester, isophthalmic polyester or vinyl ester as matrix material. Withquarter density to steel and two thirds density to aluminum, the gratingby JSECC provides high strength as ten times as rigid PVC, the sameabsolute strength standard as normal steel and absolute strength of aluminum profile.The pultruded grating, molded grating and pultruded profile from JSECChave the oxygen index beyond 32 according to China GB8924. They alsohave the flame spread rating as one-grade in terms of ASTM E-84. Furthermore,the flame spread rating of high fire-retardant vinyl ester grating is less than10 and obtains the recognition from ABS. Safety is guaranteed by specialformulation to meet the requirements of flame resistance for engineeringprojects.
