By 2025, extreme climate events will further ravage the Earth. Extreme heat zones will expand, Greenland's 3 million-year-old ice will melt, and China's high-temperature and rain belts will shift northward. Wildfires, droughts and floods will continue, and food production will decline. These disasters, compounded by the "heat dome" phenomenon, will unfold, further necessitating urgent ac...

At the beginning of the new year in 2024, major countries in the world, such as the United States, the United Kingdom, China, and Australia, have encountered extreme temperatures, blizzards, freezing rain, floods, etc., resulting in large losses of property and personnel. As an emerging material, FRP reinforced building products have superior material properties such as corrosion resistance, light...

Striving to achieve carbon peaks by 2030 and carbon neutrality by 2060 is a major strategic decision made by the Party Central Committee with General Secretary Xi Jinping at the core. Technological innovation to achieve the "dual carbon" goal has also become a hot topic of discussion. The ninth meeting of the Central Committee of Finance and Economics emphasized the promotion of major breakthroughs in green and low-carbon technologies and the deployment of low-carbon cutting-edge technology research, highlighting the important supporting role of technological innovation in achieving carbon peaks and carbon neutrality.
Compared with traditional metal materials, FRP bolts and nuts and pultruded profiles have many characteristics of light weight, high strength, no rust, insulation, non-magnetic, low thermal conductivity, maintenance-free, and long service life，which plays an important role in earlier realization of the "carbon" target.
During the use of traditional metal bolts and profiles, due to the long-term volatilization of corrosive gases in the sewage tank, the corrosive effect on metal materials is very serious. Companies often have to replace them every 2 to 3 years, resulting in huge waste of resources and the high cost of maintenance pressure. Recently, through cooperation with some engineering companies, our company has used FRP bolts and nuts and pultruded profiles in a sewage tank environmental protection roof project in Gansu province. The service life of these products can reach more than 20 years, which is beneficial to reduce costs for environmental protection companies ,maintaining pressure, saving money, and reducing the emission of waste gas and waste water and other pollutants, is conducive to the development of the "dual-carbon" business.
