Surface treatment

• Mirror polished: to obtain a highly reflective mirror effect, presenting a luxurious and dazzling luster.
• Brushed: Forms a fine silky texture, presenting an understated and elegant texture.
• Sandblasting: Forms a uniform matte surface, presenting soft and durable features.
• Polishing: Utilizing machinery to polish the metal surface to a smoother finish.
• Etching: Engrave various exquisite patterns.
• Embossing: Patterns can be customized to a certain size, with a certain texture on the surface.

Mirror polishing grade & roughness standard

6K: Coarse grinding and polishing (roughness 0.01-0.08μm), the effect is slightly worse than that of ordinary mirrors.
‌8K: The most common grade of mirror stainless steel plate (roughness 0.01-0.04μm), the effect is comparable to that of ordinary mirrors.
‌10K: Fine grinding and polishing (roughness 0.02-0.16μm), the effect is comparable to that of ordinary mirrors.
‌12K: Ultra-fine grinding and polishing mirror for optical purposes (roughness 0.012-0.03μm), the surface effect is more refined.

How Is Gold Stainless Steel Made?

1. Process Before Gold Color Coating

1) Select stainless steel such as 304, or 316 as the base material.

2) Remove the oil and impurities on the surface, by polishing treatment.

3) Pickling or passivation treatment, further grinding, and polishing.

4) Color plating, there are many ways to plate color, which can be plated into different colors.

2. Gold Coating Process

• Physical coating method (PVD): using physical methods to deposit metal (such as gold or gold alloy) on the surface of the stainless steel substrate.
• Electroplating method: through the electrolyte containing gold ions, the use of electrolysis, so that the gold ions are deposited on the surface of the stainless steel substrate.
• Chemical coating method: through a chemical reaction to form a chromium oxide film, and then use electrolytic coloring or chemical coloring. The film presents a golden appearance.
• Printing method: special metal ink is printed on the surface of the stainless steel substrate to form a pattern with a golden appearance.

Wanzhi Steel Quality Control

Wanzhi Steel’s quality inspection department will analyze the chemical composition of the finished products using instruments such as spectrometers, and test physical properties such as hardness, strength, yield strength, and elongation.
The plate thickness, strip width, and length are tested, and the wall thickness of the stainless steel pipe is measured using a vernier caliper or thickness gauge.
During the production process, we will conduct drip tests, medium immersion tests, salt spray tests, etc.
