A Popular Choice for Construction: White Aluminum Coil Stock
The color coated aluminum coil is a new material that is colored on the surface of aluminum alloy. It is lightweight, corrosion-resistant, and recyclable. It is widely used in doors, windows, construction, decoration and other fields. Colored aluminum coils can be divided into a variety of colors, such as silver, champagne, gray, brown, orange, pink, etc. The white coil stock is a popular choice.
Different types and properties of coatings have different requirements for coating thickness. There are polyvinyl chloride coated aluminum coils, polyester coated aluminum coils, acrylic coated aluminum coils, fluorocarbon coated aluminum coils, silicon polyester coated aluminum coils, etc. Among them, the PVDF coated aluminum coils are the highest-grade products and have the best weather resistance and UV resistance, but they also require a higher coating thickness, generally above 25 microns.
One of the main advantages of the white aluminum coil is that it can be shaped after painting, so these tests are important to ensure that the paint is not damaged or removed during subsequent processing. Factors that affect adhesion include paint formulation, film thickness, curing temperature (PMT), line speed, handling quality, aluminum coil quality and cleanliness.
The process flow of pre painted aluminum coils is mainly divided into five steps, namely material preparation, pretreatment, paint application, curing treatment, and quality inspection. The pretreatment section mainly includes hot alkali degreasing, hot water cleaning, chemical treatment and passivation treatment.
1100 colored aluminum coil is a commonly used aluminum alloy coil. It can be used for decoration and protection of building exterior walls, roofs, walls, windows, etc. It can improve the aesthetics and durability of buildings, and has very good wind and fire resistance. At the same time, there are many types of 1100 color-coated aluminum coils, which can be customized and processed according to design requirements.
Because there are too many colors for color-coated aluminum coils, Haomei Aluminum, one of the big aluminium coil suppliers in China, generally does not have them in stock. The colors can be customized according to the RAL color card or other standard color card numbers, or they can be color-matched and processed according to samples, so the delivery of the color coated aluminum coil requires certain processing cycle. Welcome to order it from us in advance.
