Chrome Plated Bars feature a durable hard chromium layer on precision-ground steel bars, providing exceptional surface hardness (HV 800-1000), superior corrosion resistance, and minimal roughness (Ra ≤ 0.2μm). These bars deliver reliable performance in hydraulic cylinders, industrial machinery, and precision equipment applications worldwide.

Critical Advantages of Our Chrome Plated Bars

Exceptional Wear Resistance & Longevity
The hard chrome plating achieves surface hardness of HV 800-1000, significantly extending service life in high-friction applications. Our bars demonstrate 3-5 times longer lifespan compared to unplated alternatives, reducing replacement frequency and maintenance costs.

Superior Corrosion Protection
The dense, pore-resistant chromium layer provides excellent protection against moisture, chemicals, and environmental factors. Our plating process ensures consistent coverage that withstands harsh operating conditions where corrosion resistance is crucial.

Reduced Friction & Enhanced Efficiency
The mirror-like surface finish (Ra ≤ 0.2μm) minimizes friction between moving components, improving overall system efficiency and reducing energy consumption. The low-friction characteristics also contribute to smoother operation and reduced heat generation.

Precision Ground for Exact Applications
Manufactured with strict diameter tolerances (h6/h7), excellent straightness (max. 0.3/1000mm), and consistent roundness, our bars ensure perfect fit and reliable performance in precision hydraulic and mechanical systems.

Excellent Adhesion & Uniformity
Our specialized plating process creates a metallurgical bond between the chrome layer and substrate, preventing flaking or peeling even under extreme operating conditions. The uniform plating thickness maintains consistent performance across the entire bar length.
