STRONGRATE molded 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.

Remarks:Items marked # with can be also done in phenolic resin,in addition to iso resin,ortho resin,andvinyl ester.

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 V (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
