Moulded grating is FRP plates with many uniform distributing rectangular and square blanks which are manufactured with molding confectioning technology. It has bilateral isomorphism mechanical features. As the ideal product for corrosion environment, it is widely used in the work platform, equipment platform, boring platform, walkway of petroleum, chemical industry, electronic industry, power industry, paper manufacturing, printing and dyeing, galvanization, ocean exploration, sewage treatment, and other industries, and it is also applicable for civil construction.
The series products have the features of crater, sand-finished, biplane, plate grate.
1.Corrosion resistance: It has excellent acid resistance, alkali resistance, organic solvent resistance, saline and other many gas and liquid medium resistance. It also has unsurpassable superiority in anticorrosion field. In terms of actual using environment, the customer can economically select pyrocatechol, m-phenylenediamine and ethenyl resin as base.
2. Light weight and high intensity: the density of FRP grating isn’t larger than 2, only 1/4 of steel and 2/3 of aluminum. Its strength is 10 times of that of hard PVC, and its absolute strength exceeds those of aluminum and common steel.
4. Resistance to age: Its operational life is longer than 50 years.
3. flame retarded: the flame transmitting speed of common flame-retarded grating(ASTM E-84)doesn’t exceed 25, the flame transmitting speed of common flame-retarded grating doesn’t exceed 10 and the oxygen index isn’t lower than(GB 8924).
5.Safety: It has excellent electric insulating property, and it isn’t be punctured with 10KV voltage, and has no electromagnetic properties. It can be used in magnetism sensitive equipment. The special structure of FRP grating has antiskid and fatigue resistance.
