How to choose fiberglass grating

1. To determine what fiberglass grating panels are needed for, that is, to clarify their usage objectives. If a manufacturer in a car wash buys a grille board, they are preparing to use it as a load-bearing plate for the car wash.

Precautions for using fiberglass grating

1. Due to small density and light material, it is easy to float pipes when installing glass fiber reinforced plastic grids in areas with high underground water level. Anti floating measures such as anchor blocks or rainwater runoff diversion must be considered.

What is a new composite material?

The history of the use of composite new materials can be traced back to ancient times. The straw reinforced clay that has been used since ancient times and the reinforced concrete that has been used for many years are both composed of two materials. In the 1940s, due to the needs of the aviation industry, glass fiber reinforced plastics (commonly known as fiberglass) were developed, giving rise to the name composite materials. After the 1950s, high-strength and high modulus fibers such as carbon fiber, graphite fiber, and boron fiber were gradually developed. In the 1970s, aramid fibers and silicon carbide fibers emerged. These high-strength and high modulus fibers can be combined with non-metallic matrices such as synthetic resins, carbon, graphite, ceramics, rubber, or metal matrices such as aluminum, magnesium, and titanium to form unique composite materials. The specific strength of high molecular weight polyethylene fibers ranks first among various fibers, especially their excellent resistance to chemical attack and aging resistance. It also has excellent high-frequency sonar permeability and seawater corrosion resistance. Many countries have used it to manufacture high-frequency sonar fairs for ships, greatly improving their mine detection and sweeping capabilities. The composite new materials developed by Sijia New Materials in China represent a high level of domestic development. In addition to military applications, high molecular weight polyethylene fibers also have broad application prospects in fields such as automobile manufacturing, shipbuilding, hospital equipment, and sports equipment. Once this fiber was introduced, it attracted great interest and attention from developed countries around the world.
