GRC/GRP/GRG

Glassfibre Reinforced Plastics (GRP) or Fibre Glass Reinforced Plastics (FRP) are essentially structural materials that belong to the larger family of composite materials. As a matter of fact, modern composites owe their genesis to glass-fibre reinforced polyester developed in the 1940s. The composite basically consists of e-glass fibres and polyester resin that has excellent mouldability with several desired qualities such as lightweight, high strength, high stiffness, toughness, chemical resistance, electrical properties, aesthetic appeal, etc.

Advantages

•  Easy mouldability to architectural forms and shapes
•  High strength to weight ratio
  
•  Wide performance range
  
•  Low manufacturing cost
  
•  High resistance to impact
  
•  Resistance to corrosion
  
•  Good electrical characteristics
  
•  Heat and sound insulation
  
•  Translucency and colour impregnation

Properties

• Properties of typical 4 mm thick hand lay-up GRP laminate are:
•  Glass Content        : 450 gms/sq m / mm
  
•  Impact Strength     : +40 to 45 KJ/ sq m
  
•  Tensile Strength    : +75 to 80 N/mm
  
•  Density                  : 1.6 to 1.8 gms/cubic cm
  
•  Bar of hardness     :  45-50
  
•  Pigmented gel coats  : Ultra violet stabilized colour fast, no fading
  
•  Fire properties (Surface spread of flame):
        Class 3 with general purpose resin as per BS476 Part 7,
        with special resins Class 1 can be achieved

Applications

•  Achitectural panels such as decorative column cladding, façade treatment, insulated, non insulated domes of mosques and commercial buildings.
  
•  Bath tubs, shower trays, wash basins, garden fountains
  
•  Manhole liners, septic tanks, holding tankso Portacabins, prefabricated houses, watchman booth, vending kiosks, etc.
  
•  Water tanks, A.C. covers, vanity tops
  
•  Gold and silver jewels finals for mosques and domes
  
•  Artificial rocks, garden planters
  
•  Stadium canopies, electrical enclosures
