Color-coated steel for home appliance is with good processability and decorative properties. It is widely used as front panels, side panels, back panels and inner panels of household appliances. You can find it in refrigerators, microwave ovens, washing machines, air conditioners, water heaters, display cabinets, vending machines, DVDs, computers, etc. Generally, it uses electro-galvanized, hot-dip galvanized, and cold rolled steel as the substrate. At Wanzhi Steel, we have pre-painted steel and PVC/PET coated steel sheets to choose from. Welcome to contact us for more details!

1. Great processing performance;
2. Excellent chemical resistance;
3. High scratch resistance;
4. Delicate decorative performance, etc.
1. Widely used in refrigerators, microwave ovens, bread makers, washing machines, air conditioners, DVDs, water heaters, televisions, and other household appliances;
2. Also, it is popular in freezers, display cabinets, vending machines, and other commercial appliances.
Due to its rich colors and high production efficiency, pre-painted steel is widely used for exterior walls, roofing, interior decoration, windows, doors, etc. Currently, it is also popular in transportation and home appliances. However, pre-painted steel for home appliances uses special top paintings, which makes the surface glossy. The front panel uses polymer linear oil-free polyester resin coating and the back panel uses modified epoxy painting. Also, you can find conductive and matte PPGI sheets on the market. Relatively speaking, the color coated sheet is not as smooth as the PVC/PET coated steel sheet. So it is mainly used as side panels but is not very suitable for the front panel of high-end household appliances.
PVC/PET coated color steel has a beautiful appearance, excellent processability, and superior resistance to corrosion and scratch. Besides, it can show different effects from low light to high light, pearlescent effects, and exquisite patterns. Therefore, it is widely used in refrigerators, washing machines, and other household appliances. You can find the laminating process on our Youtube Chanel.
As mentioned, the base material can be cold-rolled steel sheets, hot-dip galvanized sheets, electro-galvanized sheets, aluminum sheets, stainless steel sheets, etc. Among them, cold-rolled sheets are mainly used for exterior sheets of refrigerators and washing machines. In contrast, hot rolled steel plate is mainly used for shells of air conditioner compressors. Hot-dip galvanized sheets are mainly used in air conditioner outdoor units and back panels of refrigerators. In comparison, electro-galvanized and fingerprint-resistant sheets are preferred by high-end household appliances such as computers, VCDs, microwave ovens, washing machines, air conditioners, etc. Generally, the PVC/PET coated color steel sheet used in refrigerators is 0.7mm and 0.8mm in thickness. At the same time, that for microwave ovens is 0.5mm and 0.8mm.
Moreover, different regions have different choices for color-coated steel for home appliances. In Japan and South Korea, the side panels of refrigerators often use high-gloss single-color panels. While in North America and Europe, low-gloss panel, like the embossed panel is more popular because they can not only enhance the strength of the steel sheet during the embossing process but also cover the surface defects of the base metal.
Due to the indoor use of home appliances, there is no high requirement for weather resistance and aging performance. However, it requires higher boiling water resistance and acid and alkali resistance. In addition to its significant decorative effect, it also needs to meet some specific use requirements, such as non-toxicity, high processability of microwave oven shells, the resistance to detergents of washing machine shells, the scratch resistance of refrigerator side panels, etc. At the same time, in order to prevent scratches during stamping, the protective film needs to be retained until the end user removes it. If the protective film is released before leaving the factory, it requires 60 units of adhesive force. While if the protective film is removed by end users, it requires 180 units of adhesive force.
Actually, there is no essential difference between the color-coated steel for home appliances and construction. But home appliance panels have higher requirements for substrates and coatings. Below let’s review their differences in coatings, base metal, and applications.
In construction uses, the primer is epoxy resin paint or and the topcoat is polyester paint or other coatings with the same performance. While for home appliance uses, the primer is polyester paint and the topcoat is polyester paint or other paint with the same performance.
The color coated steel for home appliances is mainly suitable for white goods, such as refrigerators, washing machines, air conditioners, water heaters, microwave ovens, TV back panels, electrical boxes, stereos, etc. In construction, it is mainly used for roofing sheets, partition walls, curtain walls, ceilings, security doors, windows, fencing panels, etc.
Generally speaking, color-coated steel for construction requires higher strength and better corrosion resistance. This is because it is usually a part of the stress-bearing structure and is used in a complex outdoor environment. While color-coated steel for home appliances uses normal-strength steel sheets. As for base metal, hot-dip galvanized steel and galvalume sheets are commonly used for construction, while electro-galvanized sheets and cold rolled steel are generally used for home appliances.
Wanzhi Steel has an annual production capacity of 80,000 tons of color coated steel for home appliances. We employ a complete imported coating line and adopt double-coating and double-baking process. And there are also thermal lamination lines and sharing, slitting equipment, etc. at our factory. So you can find different surfaces and finishes, such as perforated steel sheets, checkered sheets, etc. Our products are widely used in refrigerators, freezers, washing machines, air conditioners, microwave ovens, water heaters, televisions, etc. In addition to common colours, pearlescent and metallic products are also available. We offer color coated steel with different base materials, finishes, and specifications. Welcome to contact us for more details!
