GFRP Hollow Oval Shap Bar
Model NO: GTI-GOH
Introduction:


We accept customization of FRP pultruded profiles according to the following requirements.

●Product section:
Be able to produce FRP pultruded profiles with any cross-section

●Color:
According to your customization. We can supply FRP profiles with various colors

●Resin matrix:
The appropriate use of resin formulations is according to the operation environment of final product and usage requirement (see media properties).
The resins used in pultrusion process are mainly general purpose resin, isophthalic resin o-benzene resin, Vinyl Ester Resins, and phenolic resins.

●Reinforced materials:
It is the support frame of glass steel which largely determines the mechanical strength and elastic modulus of pultruded products.
The reinforced materials used in pultrusion process are mainly glass fiber roving , glass fiber mat and glass fiber fabrics.

Pultrusion Products

Fibre bundles and slit fabrics are pulled through a wet bath of resin and formed into the rough part shape. Saturated material is extruded from a heated closed die curing while being continuously pulled through die. Some of the end products of the pultrusion process are structural shapes, i.e. I beam, angle, channel and flat sheet. These materials can be used to create all sorts of fibreglass structures such as ladders, platforms, handrail systems tank, pipe and pump supports.
