Color-coated aluminum coils are the surface coating and coloring treatment of aluminum plates or aluminum coils. The commonly coated aluminum coils are fluorocarbon color-coated aluminum coils and polyester color-coated aluminum coils. They are widely used for Veneer, aluminum honeycomb panels, aluminum ceilings, roof surfaces, leftover material, cans, and electronic products. The performance of the color-coated aluminium coil is very stable, and not easy to corrode. Besides, the surface layer of the color-coated aluminum coil can achieve 50 years of quality assurance after special treatment. The weight of them per unit volume is the lightest among metal materials. Color-coated aluminum coils are currently the most popular new material.

The color-coated aluminum coils are divided into polyester-coated aluminum coils (PE), and fluorocarbon-coated aluminum coils (PVDF) on the basis of the coating. The polyester coating formed by baking the surface of the aluminum plate many times can form solidly adhered continuous solid films that have protective decorative properties. It is an anti-UV coating. The polyester resin is made of a high molecular polymer containing ester bonds in the main chain, and an alkyd resin is added. The ultraviolet absorber can be divided into matt and high-gloss series according to the gloss. It can endow aluminum products with rich colors, good gloss and smoothness, as well as superior texture and feel. In addition, it can also increase the sense of layering and three-dimensionality of aluminum products. It can protect objects exposed to the atmosphere and being attacked by ultraviolet radiation, wind, rain, frost, and snow. Due to temperature differences, freeze-thaw cycles, corrosive gases, and microorganisms, the coating can play a protective role. The color-coated aluminium coil is especially suitable for interior decoration and advertising boards.
Fluorocarbon coatings of fluorocarbon polyester-painted aluminum coils are PVDF resins, mainly referring to vinylidene fluoride homopolymers or copolymers of vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers. Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the surface film formation structure. The fluorocarbon polyester color-coated aluminum coils are especially suitable for the decoration and display of indoor and outdoor decorations in public places, commercial chains, exhibition advertisements, etc.
These coated aluminum coils have the feature of flatness.
There is no compound high-temperature indentation on the surface. The board surface has no residual tension and no deformation after shearing.
Color-coated aluminum coils(https://www.chaluminium.com/aluminium-coil.html) are painted with wood grain and stone grain so it has a realistic physical texture and a vivid natural beauty. The pattern can be made at random, giving customers a wide range of individual choices, enriching the humanistic connotation of the product, and giving people more aesthetic enjoyment.

The baked varnish pattern formed by continuous coating and high-temperature baking has high gloss retention, good color stability, and minimal change in color difference. Polyester paint on color-coated aluminum coils has a 10-year warranty, and fluorocarbon paint on color-coated aluminum coils has a 20-year warranty.
High-quality aluminum materials, plastics, and adhesives are selected, and advanced composite technology is adopted. The Color coated aluminum coils have the bending and flexural strength required by the decorative board. In the four seasons, the change in wind pressure, temperature, humidity, and other factors will not cause bending, deformation, expansion, etc.
Corrosion resistance to saline-alkali acid rain, color-coated aluminum coils will not corrode and produce poisonous bacteria, will not release any toxic gas, will not cause keel and fixing parts to rust, and is flame retardant.
Color-coated aluminum coils have a rich range of colors. Whether they are residential buildings, large commercial outlets, or large-scale convention centers, color-coated aluminum coils can add color to them. The good plasticity and machinability of the coated aluminum coil make it an ideal material for various architectural shapes. Color-coated aluminum coils have given architects, designers, and owners a bespoke color space for outside walls and ceilings, and they are the best material for architectural modeling. Whether it is a multi-functional large building or a unique and creative new building, the color-coated aluminum coil can always meet the different requirements of modern and classical architectural styles and make the building more colorful. Color-coated aluminum coils are used in many fields such as electronic appliances, instruments, lighting, packaging, and home decoration.

Colour-coated coils and sheets are widely used pre-engineered building materials. It is a versatile product used for various applications, including home appliances, furniture, airports, industrial, and warehouses.
Colour-coated steel sheets and coils use steel coils as substrates and are coated with various organic coatings. These pre Coloured steel sheets and coils are manufactured by the top structural steel company, APL Apollo Tubes. It also offers excellent electro-resistance as a high-quality PEBsteel structure solution.
The colour-coated steel coils are produced as pre-painted steel sheets and then cut to size and marketed as the finished products. The sheet&#;s colour comes from the steel colour-coated coils. Pre-painted steel coils are predominantly used to improve the aesthetic value of PEB structures. Apart from this, it offers other advantages such as durability and corrosion resistance.
Several companies that manufacture steel also produce colour-coated products. It is confusing to buy the best colour-coated products. This blog will share the factors to consider when purchasing colour-coated structural steel sheets.
How to Choose Color-coated Coils and Sheets from the market?
The construction material will not only meet your expectation but also reduce the purchasing costs. Consider the following factors when choosing pre-painted steel products:
Measure Coating Thickness
Whenever buying colour-coated sheets, it is important to check the coating thickness of the product. Substrate and coating thickness may vary depending on the application, use environment, and durability. The thickness of the coating will increase its durability and prolong its life.
Must be Hot-Dipped Galvanized Sheets
Before finalizing the structural steel coil/tubes, one major thing to consider is whether it is a galvanized sheet or a galvalume sheet. Manufacturers of color-coated sheets use hot-dip galvanized and galvalume sheets for their superior corrosion resistance. Its mechanical properties make Galvalume sheets suitable for industrial projects in highly corrosive environments.
Types and Colors of top/back paint
PE(polyethylene), SMP (mix of Silicon & Polyester), HDP, and PVDF are four popular top paints that differ in hardness, adhesion, durability, and other qualities. The most often coating used is PE which offers average durability, decent hardness and flexibility, and is available at a reasonable price. SMP is better than HMP because it is durable, glossy, and colour-retaining. However, it is less flexible. HDP is more durable than PE and also less expensive. PVDF has outstanding durability and flexibility, but it is less colourful and more expensive. The top coat should follow these factors such as the use purpose, the environment, the designed life, durability, processing method, etc. to prolong the life of the PEB steel sheets.
Back paint is often chosen based on the application and use environment. When the environment is not corrosive, one layer of paint is sufficient. The back paint must adhere well if it is pasted with thermal insulation materials.
Buy by Weight Rather than Per Piece
To construct their pre-Engineered steel building, you should purchase steel priced by weight rather than per piece. When working on large metal projects, precise weight calculation is crucial to reducing the weight economically and physically. Knowing the weight of steel sheets is essential if you plan to transport or lift them with cranes or hydraulic equipment.
In Summary!
Hopefully, the list of factors will help you to buy suitable colour-coated sheets from the market.
