With the rapid development of my country’s home appliance industry, the advantages of small investment and low cost of steel plate coating have continued to develop in the home appliance industry. At present, domestic large-scale and strong home appliance companies have used film-coated steel plates for various home appliance panels. The use of coated steel sheets for home appliances abroad is mainly based on product design needs, environmental protection needs, constraints in the production process, and raw material costs and economic balance.
