Original color polished stainless steel

1. Characteristics
Ultra-high reflectivity: The surface is close to an optical mirror surface, capable of clearly reflecting images.
Texture-free: After fine polishing, almost no processing marks can be seen.
Easy to clean: The smooth surface is not prone to stains and is convenient to wipe.
Easy to show fingerprints and scratches: The high-gloss surface is prone to leaving fingerprints, water stains and fine scratches.
2. Processing technology
The manufacturing of original color polished stainless steel usually involves multiple processes:
Rough grinding: Use a abrasive belt or grinding wheel to remove the surface oxide layer and defects.
Medium grinding: Use finer abrasive to further smooth the surface.
Fine polishing: Mirror-like treatment is carried out using a cloth wheel and polishing paste to achieve a No. 8 reflective effect.
Electrolytic polishing (optional) : Enhances gloss and corrosion resistance through chemical electrolysis.
3. Common Applications
① Architecture and decoration
Hotel/shopping mall elevator doors & walls
High-end office building curtain wall decoration
Art sculptures & indoor mirror installations
② Home appliances & Furniture
High-end refrigerator and oven panels (such as Sub-Zero and Miele)
Kitchen countertop, range hood
Modern minimalist style furniture
③ Industry & Luxury Goods
Medical devices (shells of some high-end equipment)
Watch cases, jewelry display cabinets
Automobile trim strips (such as the interiors of Mercedes-Benz and BMW)
4. Comparison of advantages and disadvantages
Advantages and disadvantages
Luxurious and high-end, with strong visual impact. It is prone to leaving fingerprints and water stains
✔ It has better corrosion resistance than ordinary stainless steel. The surface is prone to scratches and the maintenance cost is high
✔ Suitable for sterile environments (easy to clean) × Relatively expensive (complex to process)
5. Maintenance and Care
Daily cleaning: Use a soft cloth and neutral detergent (such as dishwashing liquid), and avoid steel wool or strong acid and strong alkali detergents.
Anti-fingerprint treatment: Anti-fingerprint oil (AF Coating) can be sprayed to reduce stain residue.
Repair minor scratches: Wipe with special stainless steel polishing paste and a soft cloth.

Brushed stainless steel

1. Characteristics
Matte low reflective: The surface presents a fine linear texture, with soft light scattering that is not dazzling.
Wear-resistant and scratch-resistant: The brushed texture can effectively hide minor scratches during daily use.
Modern minimalist style: Suitable for industrial style, minimalism, light luxury and other design styles.
Anti-fingerprint: It is more dirt-resistant than mirror polishing, but fingerprints may still remain (anti-fingerprint treatment can be done).
2. Processing technology
The manufacturing of brushed stainless steel usually adopts the following methods:
Mechanical wire drawing: Use abrasive belts, nylon wheels or wire brushes to grind the surface in a single direction to form a uniform texture.
Electrolytic wire drawing (optional) : Through chemical + current treatment, the texture is made finer and more uniform (higher cost).
Anti-fingerprint treatment (AF Coating) : An additional nano-coating can be added to reduce fingerprint residue.
Common drawing grades (classified by the coarseness of the texture) :
Fine Hairline: With a fine texture, it is suitable for precision household appliances and electronic products.
Regular Hairline: The most commonly used, it strikes a balance between beauty and wear resistance.
Coarse Brushed (coarse Brushed) : the texture is distinct and has a stronger industrial feel, such as in ships and mechanical equipment.
3. Common Applications
① Architecture & Decoration
Elevator car, door casing, curtain wall decorative strips
Wall and column edge banding for shopping malls, hotels and office buildings
Stair railings, skirting boards
② Home appliances & Furniture
High-end range hood, oven and refrigerator panels (such as Siemens and FOTILE)
Cabinets, bars, dining table tops
Lighting fixtures and furniture frames (such as coffee tables and TV cabinets)
③ Industrial & electronic products
Mechanical equipment enclosures (such as CNC machine tools, food processing equipment)
Laptop cases (such as early models of MacBook)
Watch straps, mobile phone midframes (such as some flagship models)
4. Comparison of advantages and disadvantages

Advantages

Disadvantages

Wear-resistant and scratch-resistant, hides scratches

It is not as high-end as mirror surface and has a lower gloss

Anti-fingerprint performance is superior to mirror polishing.

The texture direction must be consistent; otherwise, it will affect the appearance

Low processing cost and high cost performance

Oil stains may seep into the texture and need to be cleaned regularly

5. Maintenance and Care
Daily cleaning: Wipe with a soft cloth and neutral detergent. Avoid damaging the texture with hard brushes.
Stubborn stains: You can use alcohol or a special stainless steel cleaner and wipe along the direction of the wire.
Repair scratches: If there are deep scratches, they need to be re-polished along the grain with a brushed cloth.

Snowflake sand stainless steel

1. Core features
Surface characteristics
Fine frosted texture: Utilizing random track grinding technology, it forms a uniform and irregular snowflake-like texture
Matte low reflection: Light diffuse reflection rate 8-15%, soft and comfortable visual effect
Three-dimensional touch: The surface Ra value is 0.4-1.2μm, with a slight concave and convex three-dimensional effect
Performance advantage
Outstanding anti-fingerprint performance (70% less fingerprint display than mirror surface)
Outstanding wear resistance coefficient (Mohs hardness can reach 5-6 grades)
Compliant with food-grade hygiene standards (no dead corners structure, easy to clean thoroughly)
2. Precision processing technology
① Substrate pretreatment
Select 304/316L medical-grade stainless steel plates and first undergo electrolytic polishing to remove the surface stress layer
② Multi-stage grinding system
Primary grinding: Use a #180-240 mesh fiber grinding wheel to remove mechanical marks
Precision grinding: Planetary grinding heads are used in combination with #400-600 mesh ceramic gravel
Final treatment: Three-dimensional oscillation grinding (amplitude 0.1-0.3mm)
③ Surface passivation
Passivation treatment is carried out through a mixed solution of nitric acid and hydrofluoric acid to enhance corrosion resistance
3. High-end application scenarios
① Medical and health care field
Surgical instrument storage cabinet (compliant with GMP certification standards)
Nuclear magnetic resonance equipment casing (without magnetic interference)
Sterile laboratory countertop
② Food industry
The inner wall of the beer fermentation tank (resistant to acid and alkali corrosion
Meat processing equipment workbench
Commercial kitchen range hood system
③ Architectural decoration
High-end office building elevator cabins (such as Shanghai Tower)
Anti-glare walls for subway stations (Beijing Daxing Airport Line)
The frame of the museum's cultural relic display case
