How to connect fiberglass profiles (I-shaped, grooved, round tubes, square tubes)

The basic components of FRP profiles are resin and glass fiber (including cloth, felt, etc.). It uses fiber (including glass fiber, carbon fiber, organic fiber and other metal and non-metal fibers) as reinforcing materials. It is composed of resin as the adhesive agent and other auxiliary materials (main auxiliary materials: release agent, curing agent, catalyst, sealing agent, UV light stabilizer, mold cleaning water, gel coat, etc.). It has a series of properties such as high temperature resistance, corrosion resistance, high strength, small specific gravity, low moisture absorption, small extension and good insulation.
