Glass Reinforced Polyester (GRP)

Modern industries demand structural materials that are lightweight, strong and versatile evaporating materials that resist corrosion and temperature extremes and which deliver freedom of design and low system costs. The ideal solution is a family of structural, fibre reinforced thermostets: SMC (Sheet Moulding Compound) and DMC (Dough Moulding Compound). These materials combine mechanical and physical properties with the lowest system cost, without compromising quality.

Exceptional electrical and UV properties make GRP the material of choice for outdoor electrical enclosures.


Dough Moulding Compound (DMC)

Dough Moulding Compound (DMC)
  • Most of Allbro's products are manufactured from DMC and can be manufactured in small quantities and different colours
  • Ideal for moulding small integrate parts
  • Corrosion resistance
  • Easy installation
  • High performance
  • Low maintenance

Sheet Moulding Compound (SMC)

Sheet Moulding Compound (SMC)
  • Has a higher mechanical strength than DMC
  • Used for items with large surface areas
  • Or on customers request where higher impact strenght is required
  • Generally only in light grey
  • Is manufactured in large quantities only
  • Excellent surface gloss
  • Excellent Flow Properties
  • Excellent mechanical properties

GRP comes in many colors but is always Green

Energy use is an important element in the total environmental impact of a product. Producing materials from base materials requires energy in each step of the process. A way to compare the energy use for the production of a part is to calculate back to equal properties. In the graph below the relative use for producing a part with equal tensile strength and equal tensile stiffness is represented:

“ a part produced in SMC requires 5-7 times less energy to be produced than producing the same part in steel, aluminium or thermoplastic materials at equal strength”
