The advantages of color coated aluminum sheet/coil----PPALU

The processing and application of Color-coated aluminum sheet/coil (PPALU)

The color-coated aluminum coil has a variety of colors.After the aluminum coil being processed by washing, chromizing, roll coating, baking, etc.,the surface of the aluminum coil is coated with various colors of paint coating.

Due to its light weight, bright color, easy processing and anti-rusting features,color aluminum is widely used for aluminum-plastic panels, honeycomb panels, thermal insulation panels, aluminum curtain walls, shutters, roller shutters, aluminum-magnesium-manganese roofing systems, aluminum  ceilings, household appliances, drainage system, aluminum cans and many other fields.

The advantages of Color coated aluminum coil comparing to pre-painted steel coil

Aluminum-magnesium-manganese alloy sheet is a high-quality roofing material and it is very popular in the market nowadays. It is gradually replacing the color steel tile and becoming one of the main materials in building field.

There are incomparable "three advantages" of Al-Mg-Mn alloy sheet/coil:

First, the overall cost is lower than the color coated steel. The density of the aluminum-magnesium-manganese alloy sheet is 2.73 g/cm3, which is 1/3 of the density of color coated steel. In the case of the same weight and the same thickness, the square space of the color aluminum is three times of the color coated steel. For example: If you buy a ton of aluminum-magnesium-manganese alloy sheet/coil,you can have three times volume comparing to buy color coated steel.

Second, the aluminum-magnesium-manganese alloy sheet/coil comes with anti-corrosion properties. The color coated steel tile will be corroded after 3-5 years of usage.If the situation is serious, large-scale replacement have to be carried out, and the cost will be increased.The aluminum-magnesium-manganese alloy sheet/coil can have the service life of 50 years without any damage. Especially in the areas where acid rain is heavy and serious and corrosion speed is fast, it has been already a big trend to replace color coated steel sheet with color coated aluminum.

Third, the cost of recycling is high. If the color coated steel is corroded, the cost of recycling is around a few cents per kilogram,which means if you try to sell out the old steel sheet,you almost get back nothing.If you try to sell out the old color coated aluminum sheet,you can get 85%-95% of original cost back.
