Structural profiles are manufactured using a pultrusion process (polymerisation of a profile pulled through a heated die) and may contain up to 70% fibreglass, ensuring high mechanical resistance.
GRP (Glass Reinforced Plastic) pultruded profiles are made using thermosetting resins as a chemical-resistant matrix.
The matrix material is based on an isophthalic polyester resin system which binds with the glass fibres and gives the chemical resistance to the final product. Other types of resin are also available, such as vinyl esters, acrylics, and self-extinguishing halogen-free resins with low smoke emissions. The resin systems are all certified to AFNOR or ASTM standards.

The mechanical reinforcement uses unidirectional fibreglass filaments of E-glass roving. Reinforcements and protection (the hallmark of EUROGRATE® quality). Every EUROGRATE® pultruded profile is manufactured using continuous multidirectional glass mats that increase transverse mechanical resistance. A polyester veil is incorporated on the surface, ensuring protection from UV radiation and weathering.
EUROGRATE® pultruded fibreglass profiles are designed to be used as structural supports with all the necessary safety guarantees.
TECHNICAL CHARACTERISTICS OF PULTRUDED PROFILES:
corrosion resistance: pultruded profiles normally use isophthalic resin, ensuring excellent corrosion resistance. (Other resins are available on request).
