frp shutter

The FRP shutters are adopted unsaturated polyester resin as the basic material, glass fiber roving and fabric as the reinforced material .FRP shutters prominent merits include:

1st, light weight, high strength: frp section density is about 1.8, its density approximately is 1/4 of steel density, 2/3 of aluminum density, but the intensity is very big, its longitudinal strength is close to the common carbon steel, the bending strength and the modulus of flexure elasticity are 8 ~ 10 times of P V C section, thus the wind pressure resistence performance reaches the national standard GB7106 I level.

2nd, size stable: the frp coefficient of thermal expansion is approximately 1/4 of PVC plastic which is filled by calcium carbonate, the temperature changes cannot affect switch of windows and doors, the stability is better than metal.

3rd,anti-corrosive, anti-aging: frp is a excellent anti-corrosive material, it has the good resistivity to acid, alkali, salt, majority of organic matters, seawater as well as microorganism. FRP windows and doors is stainless and decays, it is suitable for raininess moist coastal area and chemistry aging resistance of plastic sections is inferior than the thermosetting frp, the aging resistance of frp windows and doors is good, the service life is long. The performance are stable below -40 ~ 80 ℃, the P V C service life is 15 years, it is the same with construction, -40 ~ 80 ℃, which reduces trouble of replacing windows and doors.

4th,decorative performance is good: the hardness of frp section is high, the surface is smooth after polishing, it is easy to paint. It may painted all kinds of coating, the color is various, scrub resistance, fastness, the impression is comfortable.
