FRP grating cover plate: the "iron heart army" in building materials
FRP grating and FRP cover plate are made of glass fiber as reinforcing material, unsaturated polyester resin as matrix, and molded as a whole by glass fiber interweaving and resin casting. The product is composed of a number of symmetrical lattices, and has bidirectional isotropic characteristics in the vertical and horizontal directions. Advantages of FRP grating cover:
1. Corrosion resistance: it is stainless, non-mildew, non-rot, does not require paint, and can withstand the corrosion of many gas and liquid media;
2. Easy installation: The use of FRP grating greatly reduces the weight of the components, thus reducing the weight of the supporting structure, and the installation does not require lifting equipment, which is economical and convenient.
3. Safety: In the process of installing and using FRP grating, no electric spark will be generated due to collision, especially suitable for use in flammable and explosive environments. In addition, the grating with anti-skid surface layer can prevent slipping , to reduce accidents.
4. Fatigue resistance: The FRP grating cover has some elasticity, which makes people who work on it feel comfortable for a long time. As a working platform, it reduces the tension on the legs and back of the staff and increases the comfort of work, thus Improve work efficiency, recommended by human engineers;
5. Light weight: its specific gravity is about 1.8, and its weight is only 1/4 of steel and 2/3 of aluminum;
6. High strength: its strength is ten times that of rigid polyvinyl chloride, and its absolute strength is much higher than that of aluminum, reaching 1.7 times that of ordinary steel;
7. Good comprehensive economic benefits: Compared with ordinary carbon steel, the overall cost of FRP grating cover plate is low. Although its one-time investment is higher than that of ordinary carbon steel, due to its long service life, it can generally be used for 20 years without maintenance , so its comprehensive economic benefit is much better than that of carbon steel.
