Stainless steel applications

We supply stainless steel coils or sheets in various series, featuring minimal dimensional tolerances and high quality, suitable for diverse applications including:

• Home Appliances: Washing machine drums, refrigerator door panel frames, electric water heater liners, etc.
• Food Service Equipment: Food truck countertops, various utensils (spoons, chopsticks, forks, etc.), trays.
• Food Industry: Stainless steel tanks (storage tanks, reaction tanks, fermentation tanks, pressure vessels, etc.) and various food processing machinery.
• Medical Field: Handles for surgical instruments, IV stands, medical sterilization cabinets, and medical equipment housings.
• Architectural Decoration: Elevator cabins, building curtain walls, interior trim strips, and more.

Stainless steel features

1. Corrosion resistance: Stainless steel has good corrosion resistance, this performance is mainly due to the stainless steel contains chromium, chromium and oxygen reaction to form a sodium chromate layer, effectively reducing the probability of corrosion of stainless steel.

2. High strength: Stainless steel has high strength and hardness, can withstand greater pressure and tension, often used in a variety of heavy-duty work environment.

3. Machinability: Stainless steel has good elasticity and plasticity, and can be used in a variety of molding and processing methods, such as welding, cold processing, precision machining and so on.

4. Low maintenance cost: Stainless steel is easy to clean and not easy to adsorb dust, so the maintenance is relatively simple.

5. High safety: Stainless steel does not contain radioactive substances, which is not harmful to the human body, in addition, stainless steel can be recycled, causing little pressure on the environment.

Packaging Details

Surface Types We Can Supply

• 1D (matte): The surface has discontinuous granularity and presents a matte effect overall.
• 2D: It is a slightly glossy silver-white.
• 2B: It has better gloss and flatness than 2D, and is silver-white overall.
• BA (bright surface): The surface has excellent gloss and high reflectivity, just like a mirror.
• No.3 (coarse sand surface): It has good gloss and the surface presents coarse grains.
• No.4 (fine sand surface): Appearance: It also has good gloss, but the surface presents fine grains, which is more delicate than No.3.
• HL (hairy surface): It is silver-gray and has hairline stripes on the surface.
• 8K (mirror surface): It presents a perfect mirror effect.
