Pultruded FRP GRP Grating Corrosion Resistant Heavy Duty Assembled
The replacement product of traditional metal grating in the corrosive environment of pultruded fiberglass grating Pultruded fiberglass grating is a composite structural component formed by pultrusion process using resin and glass fiber as the matrix, which is used to replace traditional metal grating in corrosive environments. It has lightweight, high strength, corrosion resistance Flame retardant and anti slip properties, suitable for operating platforms, channel covers, and other scenarios in the fields of petroleum, chemical, and power. Chinese name: extruded fiberglass grating The product is assembled from extruded fiberglass profiles and is an ideal replacement for traditional metal grilles in corrosive environments Also known as fiberglass grating, fiberglass extruded grating This product consists of "I" - or "T" - shaped load-bearing profiles, connecting profiles, and spacing profiles, which are fixed with adhesive to form a grid. The pultrusion process results in a glass fiber content of over 60%, Service life. The surface is enhanced with anti slip grooves or sandblasting treatment to enhance safety, and does not require paint maintenance. Fiberglass grating is assembled from extruded fiberglass profiles and has the characteristics of light weight, high strength, corrosion resistance, anti slip, aging resistance, impact resistance, easy opening and cutting, and will not scatter. It is widely used in petroleum, chemical, power, and other industries Work platforms, equipment platforms, stair treads, channel covers, and walkways in industries such as electroplating are often used as alternative materials to traditional metal grilles in corrosive environments. 1、 Corrosion resistance: Fiberglass extruded grating has excellent corrosion resistance and can withstand corrosion from various gas and liquid media such as acid, alkali, organic solvents, and salts to varying degrees. Due to its lower resin content on the surface compared to molded grating, its corrosion resistance is superior It can be slightly inferior to molded grilles. According to the requirements of actual usage scenarios, it is economically feasible to choose ortho -, meta -, or vinyl based resins as matrix materials. 2、 Lightweight and high-strength: Fiberglass extruded grating is formed by impregnating and heating reinforcing materials such as glass fiber, continuous felt, and surface felt with resin through extrusion molding. High fiberglass content (over 60%) Product Category The extruded fiberglass grating can be mainly divided into three categories based on product thickness: 10-30mm, 31-50mm, and over 50mm. Among them, the 31-50mm type holds an important position in the market [2-3]. Load bearing profiles: mainly composed of extruded "I" or "T" profiles. Connecting profiles: Their function is to connect load-bearing profiles, mainly using various round bars or shaped bars formed by extrusion and stretching. Application field Pultruded fiberglass grating, due to its corrosion resistance, high strength and other characteristics, has replaced traditional metal grating in various specific scenarios [4]. Its main applications include corridors, stair treads, and docks [2-3]. In addition, this product is also suitable for harsh environments such as chemical plants, sewage treatment plants, and marine engineering [4]. In these fields, the core advantage of pultruded FRP grids lies in their corrosion resistance and aging resistance
