Analysis of FRP pultruded profile products
Compared to traditional materials such as steel, aluminum and wood, FRP extrusion profiles have virtually no maintenance costs. They are often used in areas such as chemical processing plants, marine construction, food and beverage processing, petroleum refining, paper industry, sewage treatment and transportation.
Glass pultruded profiles are equal cross-section structural profiles molded by continuous pultrusion process. FRP pultruded profiles have many advantages, corrosion resistance, light weight and high strength, good dimensional stability, and at the same time have the characteristics of insulation, non-conductive, flame retardant, beautiful and easy to maintain, it is compared with traditional materials such as steel, aluminum, wood, almost no maintenance costs. FRP extruded profiles are often used in areas such as chemical processing plants, marine buildings, food and beverage processing, petroleum refining, paper industry, sewage treatment and transportation.
Extruded profiles provided by Hongpeng include round bar, round pipe, angle steel, square pipe, channel steel, I-beam, T-beam, etc. Chemical platforms and guardrail systems assembled with extruded profiles and molded connectors are characterized by corrosion-resistance, lightweight and high-strength, strong structure, beautiful appearance, easy installation, etc., and are widely used in chemical industry, power generation and other industries.
