The modern steel structure wall and roof system will consider more technical points in the design stage, and the glossiness of the material surface tends to be lower, which will not cause light pollution to the environment.
Better strength and lighter weight, reducing overall steel usage.
The lifespan of the photovoltaic system is 25 years, but the roofing material cannot achieve the same service life. The cost of replacing the roofing material midway is too high.
The future market trend is:; Glossiness of 7-9 °, materials tend to be alloy, and materials with better corrosion resistance are the future market trend.
