frp stair tread. The production process of FRP results in less waste compared to traditional materials. Additionally, the long lifespan of FRP reduces the need for replacements, further minimizing environmental impact. In a world becoming increasingly conscious of eco-friendly practices, FRP stair treads stand out as a green choice for both residential and commercial buildings.“It is of great significance to establish a joint laboratory of composite materials with Sinochem International. The two sides will jointly promote technology development, results transformation and industrial application in related fields such as carbon fiber and solidified resins. We also will explore the collaborative innovation model of the technology joint research of a scientific research institute and an industrial group.”
