The main material of the grille is fiberglass, which is made of fiberglass yarn and resin. Its corrosion resistance depends on the type of resin. Therefore, when selecting fiberglass grilles, the economical resin type should be selected based on the corrosive medium used, performance description, and corrosion resistance table. Generally speaking, there are three types of resins commonly used in fiberglass grilles, which are ortho benzene, meta benzene, and vinyl. The ortho benzene type has general corrosion resistance and can withstand atmospheric aging, seawater corrosion, etc· Long term use temperature -50-60 ℃; The meta benzene type is mainly used in municipal construction and has excellent corrosion resistance. It can withstand medium concentrations of inorganic acids and alkalis, various salts, and other environments. It can be used for a long time at temperatures ranging from -50 to 90 ℃; Vinyl type is mainly used in the chemical industry. It has excellent corrosion resistance and can withstand harsh corrosion environments such as acid, alkali, salt, solvent, and acid-base alternation. The long-term usage temperature is -50-110 ℃. You need to choose different resin types of fiberglass grilles based on different usage environments and corrosion resistance requirements.

1. High strength: Its strength is ten times that of rigid polyvinyl chloride, much stronger than aluminum, reaching the level of ordinary steel;

2. Corrosion resistance: It does not rust, mold, or decay, does not require paint, and can withstand corrosion from various gas and liquid media;

3. Lightweight: Its specific gravity is about 1.8, and its weight is only a quarter of that of steel and two-thirds of that of aluminum;

4. High safety: During installation and use, sparks will not be caused by collisions, making it particularly suitable for use in flammable and explosive environments. In addition, the grille with an anti slip surface can prevent slipping and reduce accidents;

5. Good comprehensive benefits: Compared with ordinary carbon steel, glass fiber composite materials have lower costs. Although their one-time investment is higher than ordinary carbon steel, due to their long service life, they can generally be used for 20 years without maintenance, so their comprehensive economic benefits are much better than using carbon steel.

6. Anti fatigue: It has a certain elasticity, making people feel comfortable for a long time. As a work platform, it reduces the pressure on the legs and back of workers, increases work comfort, and thus improves work efficiency.

7. Easy to install: The weight of the components is reduced, thereby reducing the weight of the supporting structure. No need to use lifting equipment during installation, which is both economical and convenient;
