Color coated coils are a type of building material, and their quality cannot be reflected in the short term. Currently, most users in the market still rely on quotation as the main factor to determine the selection of Baosteel color coated coils. In fact, this is very unscientific. Although it saves investment at once, there are problems such as increased maintenance costs and shortened service life.
Color coated roll coating:
There are many factors to consider when choosing a coating, including coating type, coating thickness, coating color, and coating glossiness. In addition, sometimes the requirements for the primer and back coating of the coating also need to be considered.
Color coated coil coating
At present, hot-dip galvanizing and aluminum zinc plating are widely used for color coating in construction. The thicker the coating, the better the corrosion resistance.
As for the choice of hot-dip pure zinc or hot-dip aluminum zinc coating, it mainly depends on the acidity and alkalinity of the usage environment. Zinc and aluminum are both amphoteric metals, but their behavior in acids and bases still differs. Pure zinc performs better than aluminum zinc alloy in alkaline media. The performance in acid pickling medium is the opposite. Therefore, it is recommended to use aluminum zinc color coating in relatively acidic environments, and hot-dip pure zinc color coating in relatively alkaline environments. According to usage experience, wet wood, concrete, etc. should not be in contact with aluminum zinc plated substrates for a long time.
Color coated coil is a product made by coating one or several layers of organic coating on the surface of hot-dip galvanized sheet, hot-dip aluminum zinc sheet, electroplated galvanized sheet, etc. after surface pretreatment (chemical degreasing and chemical conversion treatment), and then baking and curing. It is also named after colored steel coils coated with various organic coatings, abbreviated as colored coated coils. The color coated steel strip using hot-dip galvanized steel strip as the substrate not only has a zinc layer for protection, but also has an organic coating on the zinc layer for coverage and protection, preventing the steel strip from rusting. Its service life is about 1.5 times longer than that of galvanized steel strip.
Application of color coated rolls: Color coated rolls are lightweight, aesthetically pleasing, and have good corrosion resistance. They can also be directly processed and are generally available in gray white, sea blue, and brick red colors. They are mainly used in advertising, construction, home appliances, furniture, and transportation industries. The coating used for color coated rolls should choose suitable resins according to different usage environments, such as polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc. Users can choose according to their intended use.
Product features: Good durability, corrosion resistance, and longer lifespan compared to galvanized steel plates; Has good heat resistance and is less prone to discoloration at high temperatures compared to galvanized steel plates; Has good thermal reflectivity; Has processing and spraying properties similar to galvanized steel plates; Has good welding performance. It has a good performance price ratio, durable performance, and highly competitive price. Therefore, whether it is architects, engineers, or manufacturers, aluminum zinc coated steel plates have been widely used in industrial buildings, steel structures, and civil facilities, such as garage doors, eaves gutters, and roofs.
