FRP GRATINGS
About Our FRP/GFRP Moulded Gratings
KARNI is striving to become one of India's leading manufacturers of moulded grating, Renowned for its high strength, corrosion resistance in the harshest environment, long life and safety.
We manufacture from carefully selected resin system, our grating is designed to deliver many years of reliable service, outperforming the traditional materials and made as per the high international standards.
FRP/GFRP gratings are light-weight, easy to fabricate and install. Their acceptance in many major industries has made them the first choice over steel gratings, not only for their performance but cost competitiveness as well.
Compared with steel at the installed cost stage, low maintenance and longevity span means a significantly lower life cycle cost than steel.
GRFP Moulded Gratings are available with Polyester, vinyl ester or phenolic resin. All kinds of resin are self-extinguishing and UV-stabilized.

Construction of FRP Gratings
GFRP Moulded Gratings are produced by wet moulding and hot curing in a heated mould. [cite: 85] The reinforcement consists of continuous fibre glass rovings in alternating layers, so the loads are distributed evenly in all directions.
Regularly Moulded GFRP Gratings have a polyester resin matrix. Glass content is approximately 35%.
Standard colours are green, yellow or grey. other colours are also available as per RAL codes.
