Engineering Manufacturing Process
Our chrome plated stainless steel square tubes are produced through a controlled multi-stage process:
Stainless steel tube forming
(Welded or seamless production depending on specification)
Surface pretreatment
Degreasing + acid activation to ensure coating adhesion stability.
Copper plating layer
Acts as a bonding foundation layer for adhesion strength.
Nickel plating layer
Improves corrosion resistance and surface leveling.
Chrome finishing layer
Provides hardness, mirror gloss, and surface protection.
Final polishing & inspection
Ensures uniform brightness and defect-free surface.
Functional Engineering Explanation
• Copper layer → Improves Bonding Strength and coating stability.
• Nickel layer → Enhances Corrosion resistance and leveling effect.
• Chrome layer → Provides Hardness and mirror aesthetic finish.
This structure significantly improves durability compared to single-layer decorative plating commonly used in low-end products.
Key Product Advantages
Industrial Corrosion Resistance
Combining stainless steel base and chrome coating provides strong resistance against oxidation and moisture exposure.
• Salt spray test: ≥72–500 hours (ASTM B117 standard depending on specification).
• Suitable for indoor, humid, and semi-protected environments.
High Adhesion Stability
Engineered for long-term mechanical processing and fabrication.
• Adhesion strength: ≥4B (ASTM D3359 Cross-Cut Test).
• Stable under bending, cutting, welding, and forming processes.
Precision Manufacturing for OEM Systems
Designed for industrial automation and mass production.
• Dimensional tolerance: ±0.1–0.3 mm (customizable).
• Stable batch-to-batch consistency for large-scale production.
Premium Mirror Chrome Surface
High-gloss reflective finish suitable for high-end applications.
• No pinholes, streaks, or discoloration.
• Consistent brightness across production batches.
• Enhances final product market value.
Cost Optimization for Manufacturers
Compared with polishing or painting processes:
• Eliminates secondary finishing steps.
• Reduces production cost.
• Improves manufacturing efficiency.
