The sewage treatment plant grid plate, also known as steel grid plate, originated in the United States in the 1970s. It is made of fibers as reinforcing materials, unsaturated polyester resin as the matrix, and cast into an integral mold through fiber interlaced woven resin. The product is composed of several symmetrical grids and has the characteristic of bi-directional isotropy in both vertical and horizontal directions.
1. High strength: The sturdy grid welding structure provides high load-bearing capacity;
2. Lightweight structure: easy to lift and other characteristics;
3. Beautiful appearance and durability: The hot-dip zinc surface treatment gives it excellent anti-corrosion ability, and the surface gloss is beautiful;
4. Good ventilation, lighting, heat dissipation, explosion-proof, and anti slip performance;
5. Prevent accumulation of dirt
6. It has excellent corrosion resistance to various gas and liquid media such as acid, alkali, organic solvents, and salts, and has incomparable advantages in the field of anti-corrosion. According to the actual usage requirements, ortho benzene, meta benzene, and vinyl resins can be economically selected as matrix materials.
7. Lightweight and high-strength: The density of steel grilles in sewage treatment plants is not more than 2, which is only 1/4 of steel and 2/3 of aluminum. Its strength is 10 times that of rigid polyvinyl chloride, surpassing the level of aluminum and ordinary steel.
8. The service life is over 50 years.
9. Flame retardant: The flame propagation rate of ordinary flame retardant grille panels (ASTM E-84) shall not exceed 25; The flame propagation rate of advanced flame-retardant vinyl grating shall not exceed 10. Oxygen index not less than 28 (GB 8924)
10. Safety: It has excellent electrical insulation and no breakdown at a voltage of 10KV; Non electromagnetic, can be used on devices sensitive to magnetism; The special structure of fiberglass grating also has characteristics such as anti slip and fatigue resistance.
