The pultrusion process allows the continuous production of FRP structural shapes in an automated, energy-efficient process by pulling fiberglass rovings through a resin bath or resin impregnator that completely saturates the reinforcements. The resin hardens from the heated steel pultrusion die, resulting in a strong, lightweight final product that follows the shape of the die.

The main application of pultrusion process are in the following industries:

• In the agriculture and chemical industries for manufacturing of slatted floors with enhanced strength characteristics used in the construction of livestock facilities, chemical plants.
• In the construction industry for the production of glass-fiber reinforcement, profiles, carcasses, stiffening bars for PVC-windows.
• In the aerospace industry for manufacturing of structure components of aircraft.
• In the sports and tourism industries for manufacturing of equipment exhibiting enhanced strength properties: skis, ski poles, golf course flagsticks, tent and hovel constructions, etc.
• In electrical power engineering for manufacturing of dielectric structures, fiberglass rods used in composite insulators and as supporting structures for elements of signaling blocks, and fiberglass profiles used in manufacturing of transformers and electric motors.
• In commercial production, using grains of long-fiber molding material (LLM) as a raw material for subsequent manufacturing of structures and products with enhanced strength and chemical properties.
• In the automotive industry for the production of structural and complex parts of the vehicles with enhanced stiffness, rigidity and lightness.
