GRP Electrical Enclosures

GRP Electrical Enclosures

GRP electrical enclosures are designed to house electrical switch and control equipment in harsh environments that require high levels of corrosion resistance. They are corrosion resistant, providing protection against corrosion in coastal environments and installations prone to exposure to chemicals and solvents.

Benefits of GRP

SMC (Sheet Molding Compound) is a composite of unsaturated polyester resin reinforced with glass fibre (12-50 mm long) as well as mineral filler and other additives. In addition to basic components such as polyester resin, fibre-glass and filler, SMC contains various additives in the form of thickeners, anti-adhesive agents and flame retardants.

  • Very good mechanical properties
  • Resistance to high temperature
  • Fire-resistance (self-extinguishing plastic)
  • High resistance to low temperatures
  • Resistance to weather conditions (UV)
  • High insulation
  • Easy machining (for holes and cutouts)
  • Very good anti-corrosion properties
  • Lightweight construction
