Glass fiber reinforced plastic grille is made of glass fiber interlaced weaving and resin casting and molded as a whole. The glass fiber reinforced plastic grille plate with many regularly distributed rectangular and square spaces has the mechanical characteristics of two-way isotropy.
GRP grille can be widely used in working platforms, equipment platforms, drilling platforms, walkways, etc. in petroleum, chemical electronics, electric power, paper industry, printing and dyeing, electroplating, marine exploration, sewage treatment and other industries. It is an ideal product in corrosive environment, and also suitable for civil building facilities.
I Advantages of FRP grille:
1. light weight: its specific gravity is about 1.8 per cubic decimeter, and its weight is only 1/4 of steel and 2/3 of aluminum;
2. high strength: its strength is ten times that of UPVC, and its absolute strength is much higher than that of aluminum, reaching 1.7 times that of ordinary steel;
3. corrosion resistance: it does not rust, mold, rot, and need no paint, and can withstand the corrosion of many gas and liquid media;
4. fatigue resistance: the glass fiber reinforced plastic grating plate has some elasticity, which makes people who work on it feel comfortable for a long time. As a working platform, it reduces the tension of the staff's legs and back, increases the comfort of work, and improves the work efficiency, which has been recommended by ergonomics;
5. good comprehensive economic benefit: compared with ordinary carbon steel, the comprehensive cost of GRP grille plate is low. Although its one-time investment is higher than that of ordinary carbon steel, its comprehensive economic benefit is much better than that of carbon steel because of its long service life, generally 20 years of service and no maintenance;
6. convenient installation: the use of GRP grating plate greatly reduces the weight of components, thus reducing the weight of supporting structure. During installation, lifting equipment is not required, which is both economical and convenient.
7. safety: during the installation and use of the GRP grid plate, there will be no electric spark due to collision, which is especially suitable for use in flammable and explosive environments. In addition, the grid with anti-skid surface can prevent slipping and reduce accidents.
II Characteristics of FRP grating:
1. corrosion of various chemical media, never rusting, long service life, free from maintenance. GRP grille is a kind of metal material, which is different from the traditional metal grille. Under the action of chemical medium, it will not produce electrochemical corrosion and rust, so that the structure of the material will not be damaged. Regular or irregular inspection is not required. Maintenance will not lead to plant shutdown, and will not occur due to many invisible accidents like metal grille. At the same time, it is also different from wood and other materials that will rot and mildew. It is an upgraded product of traditional iron, wood, cement and other materials.
2. light weight, high strength, and easy to cut and install. As it is compounded by resin and glass fiber, its density is small, only one fourth of that of iron and one third of that of aluminum, but its relative strength is higher than those of these metals. Its self weight is light, which can greatly reduce the foundation support, thus reducing the cost of engineering materials. It is easy to cut and install, without hot work and large lifting equipment, and only a small number of manual and electric tools, which greatly reduces the installation cost.
3. strong designability, flexible and diverse dimensions, and stable dimensions. Products can be customized according to customer requirements, such as different space sizes, different overall dimensions, different load requirements, etc. It can meet different requirements to the greatest extent and minimize the loss caused by cutting, thus saving costs for customers.
4. it has slight elasticity, which can reduce the fatigue of personnel, enhance comfort and improve work efficiency.
5. the color is uniform inside and outside, and the color can be selected at will. The color can be customized according to customer requirements to improve the environment of the production site.
