Vello pultruded profiles for window and door frames provide producers efficiency and long lasting quality.
By using glass reinforced plastic (GRP) it is possible to create a composite material with high strength and low weight. The material is corrosion resistant, maintenance free and has excellent dimensional stability.
A particular area of expertise for us involves intricate profiles with numerous details.
The coefficient of expansion of glass fibre reinforced polyester profiles is very low and almost identical to that of float glass. Expansion and contraction with changing temperatures is minimal and the profiles retain their stiffness at high temperatures.
You can make the entire window from GRP profiles or you can combine the profiles with traditional window and door materials such as wood or aluminium to achieve maximum user benefits.
The profiles can be coloured in the pultrusion process, painted in virtually any colour in our own profile painting facilities or foiled to give a textured finnish.
GRP fibre profiles are not only maintenance free,they are also well suited for use in corrosive industrial environment, being resistant to most corrosive liquids and gases.
Is a continuous production process for manufacturing fibre reinforced composite profiles. The reinforcement consisting of «roving» and «mats» and are pulled through a die where the fibres are impregnated by resin, heated and cured in the required shape. The profile is structurally stable and ready for further processing immediately after leaving the die.
