Description:Molded FRP gratings use high strength fiberglass roving as reinforcing material,together with unsaturated polyester resin. These products have the best bi-direction mechanical properties, with good chemical resistance can be achieved by using superior polyester resin. They are widely used in the power generation, sewage treatment, oil refining and oceanographic survey fields as work floors, stair treads, and trench covers for loading frames. Basic specifications of molded FRP gratings: border=0> Apart from standard panels, we can also produce gratings of different thickness, mesh and panel size. Surfaces available include concave top, smooth grating, gritted top, covered with grit, flat or decorative plating, etc. Mold resin system for FRP grating products: 1) Type O (orthophthalic polyester resin): a) These gratings can be used in seawater, weak acid, and other special environments b) Operation temperature: –50 ~ 60oC 2) Type I (isophthalic polyester resin): a) These gratings can be used in middle concentration inorganic acids, inorganic alkalis, and other special environments b) Operation temperature: –50 ~ 90oC 3) Type (vinyl ester resin): a) These gratings can be used in corrosive environments, both acid and alkali b) Operation temperature: –50 ~ 110oC 4) Type P (phenolic aldehyde): a) Has exceedingly good fire resistance, acid resistance and dissolvent resistance b) Oxygen index: 50 c) Low smoke levels, high temperature resistance 5) Long-term usage temperature: 180oC
