3, Engineering and installation is convenient: when the construction site is working at high altitude, the aluminum roofing sheet is lighter than the iron roofing sheet by nearly three times, which lightens the burden for the construction workers and the mechanical arm, and it improves the speed of construction at the same time, saves the construction time for the first party.
Advantage analysis: in today's society, labor cost is very large, which is generally 50% of construction investment, and labor cost is calculated based on construction days. Therefore, reducing labor intensity and improving construction speed is to save construction costs.
4, High added value special materials: in recent years, general glass curtain wall and metal curtain wall are used in high-rise buildings. Metal insulation materials are used on the surface of high-rise buildings, and polyurethane or other thermal insulation materials are used instead of metal materials. This kind of composite material of several hundred yuan or even hundreds of yuan per square meter is very demanding in its service life and construction difficulty. The cost of replacement is very high because of the service life. The above three advantages of aluminum roofing sheet are fully embodied on the special material with high added value.
5, The value of recovery is high: when color steel roofing sheet reaches its service life, it is basically rusty and corroded, and it is very dangerous when dismantling, and it will be sold to the recycling station at the price below the scrap iron. The basic hardness of the color coated aluminum roofing sheet is constant, and the surface state is slightly changed,so the recovery price is higher, and the user can reduce the economic loss.
Advantage analysis: if the price of HRC is 2500 yuan / ton, the price of 800 yuan / ton of scrap metal recycling, scrap steel price is about 600 yuan / ton. It is assumed that the price of aluminum ingot is 12000 yuan / ton, and the recycling price of waste colored aluminum roofing sheet is about 7200 yuan per ton. That is: the recycling rate of waste color steel roofing sheet is 24%, and the recycling rate of waste colored aluminum roofing sheet is 60%.
