What is G.R.P ?
G.R.P stands for Glass Reinforced Polyester, outside the industry it is commonly referred to as fiberglass.
Sheets of glass fiber matting are layered over a mould which is then coated with
a special resin.
The mixture is then left to set naturally or for quicker results is placed in an oven.
The hardened polymer is then decorated and polished according to the customer’s specified finish.
-
A specific resistance, 2 to 4 times higher traditional materials, allows significant save of weight.
According to applications, a G.R.P solution (70 % fibers, 30 % resin) allows a weight save, for equal resistance, up to:
- 60 % in comparison to stainless steel.
- 65 % in comparison to aluminum.
- 75 % in comparison to hot dip galvanized steel.
