Glass fiber reinforced plastic (abbreviated as FRP) grid, also known as fiberglass grid plate, is a kind of glass fiber reinforced material, unsaturated polyester resin as the matrix, after a special processing composite of a plate material with many spaces, FRP gratings can be used as structural materials for floorings with corrosive environments, trench covers, platforms, ship decks, stairs, and plank paths. Corrosion-resistant flame-retardant, non-magnetic insulation, bright colors, a variety of styles and other features alternatives.
General description: The grille is interlaced by glass fiber and molded by resin injection. The glass fiber reinforced plastic grid plate with many regular distributions of rectangular and square spaces has the mechanical characteristics of two-way homogeneity. Can be widely used in petroleum, chemical electronics, power, paper, printing and dyeing, electroplating, marine exploration, sewage treatment and other industries working platforms, equipment platforms, drilling platforms, walkways, etc., is an ideal product in the corrosive environment, but also applies to Civil construction facilities.
Due to the existence of corrosive liquids and gases, the metal in these areas is rapidly corroded. Although measures such as anti-corrosion layer are taken, the corrosion of the components is still very alarming. It not only causes bad production environment, but also affects safety production. Sometimes it has to be Discontinued maintenance, the use of FRP grids as structural materials in these areas can have very good results, it has a long life, low cost, safe, reliable, no maintenance, as well as a series of advantages. In the United States, such products have been used for more than 30 years. The production and sales of FRP gratings have been standardized, serialized, commercialized, and used in large quantities. In the rebuilding of oil fields in the Gulf region and the Middle East, experts have argued that the use of FRP grids is the most economical and reasonable material and is therefore being used in large quantities. FRP grilles are also being used in Asia, Singapore and other regions.
FRP grating performance characteristics are as follows:
1. Corrosion resistance
It has excellent resistance to acids, alkalis, organic solvents, salts, and many other gaseous and liquid media. It has unparalleled advantages in the field of corrosion protection. According to the requirements of actual use, it is economically possible to use phthalic, isophthalic, and vinyl resins as matrix materials.
2. Light weight, high strength, and easy to cut and install
Because it is composed of resin and glass fiber, its density is less than 2 kilograms per cubic decimeter, only 1/4 of steel, and 2/3 of aluminum. Its strength is 10 times that of rigid PVC, and its absolute strength exceeds that of aluminum and ordinary steel. Its light weight can greatly reduce the base support, thereby reducing the material cost of the project. The utility model has the advantages of convenient cutting and installation, no need of moving fire and large-scale hoisting equipment, and only a small amount of manual and power tools, so that the installation cost is greatly reduced.
In theory, the service life is more than 20 years.
4. Flame retardant
Ordinary flame retardant grille flame propagation rate (ASTM E-84) does not exceed 25; high flame retardant vinyl grille flame propagation rate does not exceed 10. The oxygen index is not less than 28 (GB 8924).
Has excellent electrical insulation, no breakdown at 10KV; no electromagnetic, can be used on magnetic sensitive equipment; special structure of FRP grating also has anti-skid, anti-fatigue and other characteristics.
Color can be arbitrarily chosen. We can customize the color according to the customer's requirements and improve the environment in the production site. General FRP grille colors are: yellow, black, gray, green, blue, red, transparent or translucent. The use of a single color, can also be used with the process.
The size is flexible, easy to cut, and dimensionally stable.
