Product Description

POWERGRID molded gratings use high strength fiberglass roving as reinforcing material,together with unsaturated polyester resin

Product Feature

These products have the best bi-direction mechanical properties, with

good chemical resistance can be achieved by using superior polyester

resin.

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

Application / Models

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.

Other Information

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
