FRP grating is a material widely used in modern buildings. It is made of FRP material and has excellent physical and chemical properties, so it is widely used in construction, chemical industry, electric power and other industries.
However, the classification and characteristics of FRP gratings are rarely paid attention to by people. This article will introduce in detail from the classification and characteristics of FRP grating, and show its various advantages.
Classification of FRP Grating
1. According to different opening methods, it can be divided into flat type and hollow type FRP grating. The surface shape of flat FRP grating is flat, and its porosity is not large, so it is suitable for covering building doors and windows, patios and swimming pools, etc. The hollow FRP grating is composed of many small pores, which has better air permeability and light transmission performance, and is suitable for decoration of building exteriors and indoor partitions.
2 According to the different thickness of the material, it can be divided into FRP grating with a thickness of 1mm-6mm. This FRP grating is suitable for some larger buildings with higher strength and stability.
3. According to different use environments, it can be divided into heat-resistant, wear-resistant, corrosion-resistant, anti-skid, anti-static and other types. For example, for special environments such as oil fields, it is necessary to use anti-corrosion FRP gratings; for high temperature and high pressure environments, it is necessary to use heat-resistant FRP gratings.
4. According to different production methods, it can be divided into handmade and machine-made FRP gratings. Hand-made FRP gratings are suitable for small batch production, which can improve production efficiency and quality; machine-made FRP gratings are suitable for large-scale star production, which can reduce costs and improve production efficiency.
Second, the characteristics of FRP grating
1. Lightweight and high strength. Since FRP grating is made of FRP material, its specific gravity is only 14-15 steel, but its tensile strength can reach more than 150MPa, and its elastic modulus, stiffness and other properties are better than steel.
⒉ corrosion resistance. The physical and chemical properties of FRP grating are superior, and it is not easy to be corroded by corrosive media such as oxidation, acid and alkali, oil, and salt.
3. Good flame retardancy. After special treatment, the FRP grating can reach the fire protection level of B1 level.
4. Good light transmission. FRP grating has excellent light transmission performance, can effectively shade, ventilate, and sound-proof, making the building cooler. 5. Simple maintenance. The surface of FRP grating is not easy to adhere to dust and other sundries, easy to clean and low maintenance cost.
6. High security. Due to the anti-slip and anti-static properties of FRP grating, it has high safety in use.
Conclusion
To sum up, FRP grating is a material with broad application prospects. Its classification and characteristics are very rich, and different use environments and needs correspond to different FRP gratings.
The FRP grating is made of a new type of FRP composite material, which has high technical content and use value. With the continuous advancement of science and technology, it is believed that FRP grating will better serve our buildings and urban life.
