Stainless steel and galvanized steel coils are among the most essential raw materials in modern manufacturing and construction. Thanks to their wide range of grades, strong mechanical performance, and excellent formability, they are widely used across major industrial sectors. In stainless steel, grades such as 304, 316, 430, and 201 dominate the market, each offering different levels of corrosion resistance, strength, and surface appearance depending on their chromium, nickel, and alloy composition. These coils are produced with various surface finishes such as 2B, BA, No.4, HL, and Mirror, each designed for a specific application—2B for general industrial use, No.4 and HL for visible home appliance components, and Mirror or BA finishes for decorative architecture and elevators. This diversity allows a single material family to serve both structural functions and high-end aesthetic requirements.
In practical applications, stainless steel coils are used extensively in the home appliance sector, including refrigerator bodies, washing machines, hoods, sinks, and industrial cooktops. The food industry also relies heavily on stainless steel for worktables, industrial kitchen equipment, and processing tanks. In heavy industrial sectors, grades from the 300 series—especially 304 and 316—play a critical role in pressure vessels, heat exchangers, piping systems, and chemical processing equipment. In architectural and decorative projects, BA and Mirror finishes are preferred for elevators, wall cladding, interior panels, and modern design structures.
Galvanized steel coils also maintain a strong position thanks to their superior corrosion resistance and cost-effectiveness. These coils are produced with different zinc coating weights such as Z100, Z140, Z180, Z275, and Z350, selected according to environmental conditions, humidity levels, and desired product lifespan. For example, Z275 is the standard for sandwich panels and roofing systems, while heavier coatings are ideal for coastal, humid, or industrial environments. Galvanized coils can further be transformed into pre-painted steel (PPGI), which is commonly used for container homes, prefabricated structures, exterior panels, and roofing sheets.
In downstream production, galvanized coils are transformed into light profiles, HVAC ducts, electrical enclosures, cooler and refrigerator components, machine chassis, and sandwich panel skins. The construction sector is one of the largest consumers of galvanized steel worldwide, supported by continuous demand from large-scale private and public projects.
From a supply perspective, a significant share of stainless steel and galvanized coils consumed worldwide comes from China, South Korea, Taiwan, Vietnam, and Indonesia. China remains the world’s largest stainless steel producer, offering competitive pricing and an enormous product range. South Korea is recognized for high-precision production, consistent quality, and strict standards, making it a preferred source for high-grade galvanized coils. Taiwan and Vietnam, supported by advanced production lines and expanding capacity, have become strong competitors in both the stainless and galvanized segments.
