1. Why do building decorative stainless steel require special surface treatment?

Stainless steel is widely used in architectural decorationCurtain walls, columns, elevator interiors, signsetc. Different surface treatments can be achieved:

• Improve aesthetics(such as mirror reflection, colored titanium plating)

• Enhanced durability(Anti-fingerprint, scratch resistant)

• Meet special needs(Anti-glare, texture decoration)

2. Comparison of 5 common stainless steel surface treatment processes

① Brushed Finish

• Features: Mechanical grinding to form matte texture

• advantage:

  • Strong wear resistance, hiding small scratches

  • Anti-fingerprint, suitable for high-frequency contact areas (such as elevator interiors)

• shortcoming: Low gloss

• Applicable scenarios: Modern style architecture, industrial style decoration

② Mirror Polish

• Features: High gloss, reflectivity >90%

• advantage:

  • Luxury visual effects (hotel, shopping mall lobby)

  • Easy to clean

• shortcoming:

  • Very easy to scratch and requires regular maintenance

  • Direct sunlight may cause light pollution

• Applicable scenarios: High-end commercial space, art decoration

③ Sandblasted Finish

• Features: High pressure spraying to form a uniform matte surface

• advantage:

  • Anti-glare, suitable for outdoor curtain walls

  • Delicate touch, hide fingerprints

• shortcoming: Long-term outdoor use may accumulate dust

• Applicable scenarios: Building exterior walls, outdoor signs

④ Etched Finish

• Features: Chemical/Laser Engraving Pattern

• advantage:

  • Customizable complex textures (imitation wood grain, geometric shapes)

  • Strong artistic

• shortcoming: High cost, maintenance requires professional cleaning

• Applicable scenarios: Art installation, brand logo

⑤ Titanium plating (PVD Coating)

• Features: Vacuum ion coating shows gold/rose gold and other colors

• advantage:

  • Stable color and extremely corrosion-resistant

  • High-end decorative effect

• shortcoming: The price is 2-3 times that of ordinary craftsmanship

• Applicable scenarios: Landmark buildings, luxury goods stores

3. Selection guide: Recommended by architectural scene

4. Maintenance cost comparison

• Low maintenance: Wire brushed, sandblasted

• High maintenance: Mirror polishing (requires frequent wipe), etching (avoid acidic cleaners)

5. Conclusion

• Pursuing cost-effectiveness: Choose wire drawing or sandblasting

• Need high-end effects: Mirror polished or titanium plating

• Customized requirements:Etching process

📌Professional advice: It is recommended to do small sample tests first for large-scale projects to observe the actual effects under different lights.
