Why is it more cost-effective to use coated aluminum coils as sandwich panel materials?

Coated aluminum sandwich panels have good thermal insulation properties. The combination of color coated aluminum panels and polyurethane can effectively block the transfer of heat due to efficient thermal insulation and heat preservation, achieve energy-saving effects.

Aluminum sandwich panels are light and easy to carried and installed, greatly shortening the construction period. Aluminum sandwich panels can be quickly installed through standardized interfaces, reducing on-site processing and material losses.

The combination of colored aluminum coils and polyurethane materials has excellent fire retardant properties, which can effectively delay the spread of fire in high temperature environments, keep precious time for personnel evacuation and fire fighting, reduce personal and property losses.

Colored aluminum coils are less susceptible to oxidation and corrosion and have a longer service life of about 20-25 years. The service life of colored steel coils is relatively short about 10-15 years, and rust and corrosion problems require frequent repairs.

It is well known that the durability of aluminum alloy materials is preferred to steel. Under the same environmental conditions, colored steel is easily corroded by natural factors such as rain, moisture and salt, leading to rust problems, shortening the service life. The frequency and cost of maintenance and renovation are higher than those of colored aluminum.

Colored aluminum coils are highly consistent with the concept of sustainable development in the construction industry. On the one hand, it reduces the pollution of construction waste to the environment. On the other hand, the high recycling value of waste aluminum is to reduce cost investment.
