Stainless steel coil/strip is one of the most popular raw materials in construction and manufacturing. Because of its unique mechanical and physical properties, stainless steel coils have been widely used in the production of kitchen appliances and industrial equipment. They are rugged, corrosion resistant, lightweight and require low maintenance. In addition, they are flexible and easy to meet the requirements of a series of design standards. In industry (especially in manufacturing), many grades of stainless steel coils can be found, each with different performance and availability.

1. Automobile industry
Stainless steel coils not only have corrosion resistance, but also relatively light in weight. Therefore, they are widely used in the automotive industry.
2. Water storage and transportation industry
Water is susceptible to contamination during storage and transportation. Therefore, the storage and transportation equipment used is critical. The storage and water transportation equipment made of stainless steel coils is the most sanitary, safest and most efficient water industry equipment currently recognized.
3. Construction industry
It is an important building material or raw material for the production of building materials in the construction industry. Stainless steel coils can be used to make decorative panels on the exterior walls of buildings and interior wall decoration. They are not only durable but also very beautiful.
In addition, it is also used in the home appliance manufacturing industry.
