GRP Pultruded Fiberglass Forms Fiberglass Tube Structure FRP Grating Pultrusion Section / Profile
Pultrusion is a continuous process using fiber reinforcements with thermosetting resin matrices. Pre-selected reinforcement materials, such as fiberglass roving, mat, woven fabrics or stitched fabric, are drawn through a resin bath in which all material is thorougly impregnated with a liquid thermosetting resin. Typical resins include polyesters, vinyl esters and phenolics. The wet-out fiber is formed to the desired geometric shape and pulled into a heated steel die. Once inside the die, the resin cure is initiated by controlling precise elevated temperature. The laminate solidifies in the exact cavity shape of the die, as it is continuously pulled by the pultrusion machine. Most any constant cross-section part can be pultruded.
The Pultruded GRP Profiles provide exceptional strength, toughness and consistency. Pultrusions offer a number of advantages over traditional materials such as steel, aluminium and timber and their use is increasing across a wide range of applications and industries.
The almost infinite variety of possible Pultruded GRP Profiles allows a high degree of design freedom. Tailored properties such as strength, stiffness, weight and colour can be engineered by product design at the early stages of development.

Fiberglass (Fibreglass) is an inorganic non-metallic material with excellent performance. It has a wide variety of advantages. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantages are brittleness and relatively wear resistance. difference. It is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is several A micrometer to more than twenty micrometers, equivalent to 1/20-1/5 of a hair strand, each fiber strand consists of hundreds or even thousands of monofilaments. Glass fiber is usually used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit boards and other fields of the national economy.
