What about the Chinese market for painted aluminum coils?

The rapid development of my country's electrolytic aluminum industry will inevitably result in changes in the scale and structure of downstream industries, particularly changes in people's consumption habits and consumer awareness, which will have a significant impact on the establishment of the aluminum downstream industry chain structure. Color-coated metal coils, for example, have seen a significant increase in price over the last ten years.

A painted aluminum coil, simply described, is aluminum that has been coated and colored on the surface. It is mostly utilized in architecture, food packaging, electronic appliances, printing, transportation, and other sectors. Color-coated metal is currently most commonly utilized in architectural decoration and food packaging in China.

Color-coated aluminum is commonly used in roofing, building curtain walls, interior wall decoration, ceilings, honeycomb panels, thermal insulation panels, rolling doors, shutters, and other architectural applications. Color-coated aluminum is primarily utilized in food cans, can lids, bottle caps, box lids, pull rings, food containers, and other food packaging applications.

Coated aluminum coil is a product of the coating industry in terms of processing technology. Ecologically friendly materials are becoming increasingly popular in the field of the building due to causes such as the construction of an ecologically friendly society, people's everyday consumption patterns, and aesthetics.

Furthermore, the anodic oxidation of aluminum sheets is superior to that of galvanized sheets; thus, coated aluminum is quickly gaining popularity. Color-coated steel is used in the production process and equipment manufacturing technology of color-coated aluminum in China. Our painted aluminum saw rapid progress in the twenty-first century.

According to the manufacturing process analysis, the pre-painted aluminum used for building materials in our country primarily uses spraying or roller coating technology, primarily roller coating. Roller coating manufacturing is distinguished by high efficiency, high output, easy quality control, good quality, high use of raw materials and coatings, minimal loss, energy savings, low cost, good economic benefits, and low pollution.

Color-coated metal for food packaging is often pre-coated with paint or DOS oil on the aluminum base material, with sheet coating and roller coating methods used. Sheet coating entails doing DOS pretreatment first, followed by sheet coating after cross-shear cutting.

Roller coating eliminates the need for DOS treatment, as roller coating is performed immediately on the surface of the aluminum substrate after cleaning. Roller coating offers apparent advantages in the manufacturing of color-coated aluminum at the moment, in terms of technological process adaptability and large-scale production.

Numerous elements are influencing the growth of the coated aluminum coil sector. However, the upstream sectors, especially the aluminum sheet, coil, and coating industries, are intimately tied to the color-coated aluminum industry. The final coated aluminum coil price will be influenced by the various aluminum coil options as well as the painting and processing expenses.
