The metal roof panel has built-in corrosion resistance characteristics. Generally, colored steel tiles will be corroded after 3 to 5 years of application. More serious cases require large-scale dismantling and replacement, which will inevitably increase the cost. Assuming that the metal roof panel is replaced, the service life can reach 50 years without being damaged by human factors. Especially in areas where acid rain is more harmful and the erosion rate is rapid, replacing colored steel with colored aluminum has long been a new trend.
High recycling value. After being corroded, the colored steel can only be recycled and sold for a few cents per kilogram. The color aluminum is basically priced between 80% to 95% of the original cost, and its recycling value is significantly higher than that of color steel tiles.
1. Light weight, high compressive strength, and corrosion resistance;
2. The roof panel can be bent or made into a fan-shaped plate;
3. During installation, there is no need to pass through the roof panel, and the length of the panel can be made endlessly
4. Waterproof layer and leak repair; Thermal insulation, sound insulation and noise reduction;
