Pultrusion is a technological method of continuous production of FRP profiles with constant section and size. The technological process is as follow: reinforcing material( such as glass fiber roving and glass fiber continuous felt), in accordance with the specific form after being impregnated by basic material(such as UPR), is continuously in curing molding through mold system to become FRP profiles with smooth surface, stable size and high strength.

Application：

Pultrusion FRP profiles are widely used in three suburban rail protection cover and holder, insulation supporter, antenna column, high voltage cable tray, high voltage power supply operating lever, generator radiator, stairs and handrail, operation platform, aisle, oil tank, switch panel and switch board room, drainage system, berth and the bottom of the sea identification marks, lever in cars and trains, the corner board, highway barrier, acoustic panel, anti-glare panel, filler holder of towers, filter plate holder and the framework of cold storage materials etc.

Pultrusion FRP grating can separate and adjust the pressure of bearing bar and make it fixed by pultrusion FRP cross bar through pultrusion FRP bearing bar. The excellent features of Pultrusion FRP grating makes it meet all kinds of requirements, and widely used in working platform, equipment platform, stair tread,trench cover, bridge plate, filler holder in the fields of petroleum, chemical industry, electricity, offshore exploration, electroplate, ship, water and waste water treatment, paper making, brewing, pharmacy. It is an ideal bearing element in corrosion environment.
