Surface treatment and application
Common surface treatment
2B surface: pickled after cold rolling, smooth and glossy, suitable for conventional industrial use.
BA surface: pickled after high temperature annealing, high brightness surface, used for decorative needs.
No.4 surface: mechanical polishing to form a frosted effect, both decorative and scratch-resistant.
8K mirror: multi-pass polishing process, high reflectivity, suitable for high-end decoration or electronic products.
Titanium treatment: titanium alloy plated surface, providing metallic texture and diverse color options.
Typical application areas
Construction industry: curtain walls, handrails, door and window frames (such as the salt spray resistance requirements of Greek coastal buildings).
Food and medical: storage tanks, pipes, surgical instruments (compliant with FDA/EFSA standards).
Industrial equipment: chemical containers, heat exchangers, ship parts.
Consumer products: kitchen utensils, home appliance housings, high-end furniture decoration.

| Hot Rolled Coil | 3.0–16.0 | 1250–2500 (customizable) | Structural parts, storage tanks, industrial machinery |
Processing services
Cutting and slitting: Customized width or length as required.
Perforation processing: various shapes such as round holes and square holes, with a hole diameter of 0.4–120mm.
Surface treatment: polishing, brushing, coating (such as PVC/PE protective film).
Advantages and value
Corrosion resistance: better than 200 series stainless steel, suitable for high corrosion environments such as coastal and chemical industries.
High temperature resistance: can withstand high temperatures of 870°C for a short period of time, and long-term working temperatures of up to 500°C.
Easy processing: suitable for stamping, bending, welding and other processes to meet the needs of complex shapes.
Economical: long life, low maintenance cost, and the overall cost is lower than carbon steel or aluminum alloy.
Environmental protection: 100% recyclable, in line with the trend of sustainable development.
