How many kinds of products can produced by FRP pultrusion machine?

FRP pultruded profiles are made of unsaturated polyester resin as the matrix, and dense continuous glass fiber wrapped with glass fiber mat as the reinforcing material. The dense fiber core layer makes the profile tough and solid, giving it good bending strength and impact strength. The glass fiber mat increases the lateral strength of the profile, and a rich resin layer is formed on the surface, giving the profile good anti-corrosion, etc. properties and can be customized and processed into various products according to customer requirements.

Products made of FRP pultruded profiles include: stair guardrails, platform and walkway guardrails, poolside fences, chemical storage tank fences, street guardrails, FRP molded parts, FRP cable trays, FRP square tubes, FRP round tubes, FRP round tubes Rods, FRP rectangular tubes, FRP I-beams, FRP brackets, FRP pultruded gratings, FRP special-shaped materials, etc.

It can be said that there are many products made from FRP pultruded profiles, and they are used in a wide range of applications, such as: chemical processing plants, marine construction, food and beverage processing, petroleum refining, paper industry, sewage treatment and transportation industries, etc.

The pultrusion process was studied as early as 1948. It was first registered and patented in the United States in 1951. It was only in the early 1970s that it truly entered the field of structural materials. After that, the pultrusion process became a widely used process technology and gradually attracted the attention of all sectors of society. With the improvement of raw materials and equipment manufacturing levels, many key technologies of the pultrusion process have made major breakthroughs and achieved rapid development.
