In its simplest form, GRP (Glassfibre Reinforced Polyester) is a material system consisting of a polyester resin matrix, Glassfibre reinforcement mats and suitable additives. GRP allows for greater design flexibility previously prohibited by the limitations of traditional building materials. GRP is non-corrosive, strong, lightweight, maintenance free, and can be erected efficiently and economically.Per unit weight, GRP is among the strongest commercial materials available; for the same cross section, it is lighter and stronger than concrete, steel or aluminum.
Compared to GRC, GRP sections are thinner, stronger and lighter.

Glassfibre Reinforced Polyester (GRP) is used extensively in many fields Structural, Marine, Construction, etc... The chemical resistance of a GRP product is dependent on the type of resin used and the quality of the fabrication process. At Gulf Precast, we incorporate premium resins and materials with quality controlled manufacturing to produce superior corrosion and fire resistant components.

The advantages of GRP can be summarized as follows:

• Excellent Corrosion Resistance to a wide range of Acids, Caustics, Chlorides, Solvents and Oxidizers

• Considerable savings in weight, against equivalent metal or cementitious based systems

• Requires no cathodic protection •Very high strength to weight ratio

•Simple and effective jointing – lower installation costs.

• Non conductive, but can be made electrically conductive, as required

•Wide range of temperature - cryogenic to 350° F ' • Fine internal finish providing excellent flow characteristics

• Good thermal insulation

• High Fire resistance, as required

•Minimal maintenance cost
