Pultruded products, profiles and tubes are used in many different applications where one or more characteristics are of interest depending on the end use.

U-beams, angles, round or square tubes are made from woven mats and rovings together with iso or ortopolyesters or vinylesters. The resin is usually formulated to meet specific demands, e.g. fire retardancy, UV-stabilisation, etc.

Characteristics:

• low weight, density is 20% steel, 70% aluminium
 
• high strength, stronger than structural steel
in terms of weight
 
• electrical insulation, superb dielectric properties
 
• thermal insulation, excellent insulating values
 
• dimensional stability at varying temperatures
 
• electromagnetic transparency
 
• corrosion resistance
