Pultruded FRP Fiberglass Structural Profiles

Fiberglass profiles, also known as fiberglass pultruded profiles, are materials carefully manufactured through the fiberglass resin pultrusion process, and are widely favored by various industries due to their excellent performance.

This type of profile is mainly composed of resin (including epoxy resin, polyester resin, phenolic resin, etc.) and glass fiber (such as cloth, felt, etc.). Glass fiber serves as the core reinforcement material, while resin plays a bonding role. Other fibers such as carbon fiber and organic fiber, as well as auxiliary materials such as release agents, curing agents, catalysts, etc., are also added to further enhance its performance. In the manufacturing process, thermosetting resin substrates undergo cross-linking under thermal action, forming a stable mesh structure that ensures the dimensional stability of the product under normal conditions and minimal post molding shrinkage.

The types of fiberglass profiles are rich and diverse, covering various specifications such as fiberglass square tubes, round tubes, rectangular tubes, round bars, I-beams, angle steels, square bars, and channel steels. These profiles not only have significant characteristics such as high temperature resistance, corrosion resistance, high strength, low specific gravity, low moisture absorption, small elongation, and excellent insulation performance, but also have become the first choice for many industries in the selection of lightweight materials due to their outstanding physical properties and wide applicability.
