FAQ

Hard Chrome Plated Steel Bars are essential components engineered for high-precision and high-durability industrial equipment. Utilizing premium steel as the base material, each bar undergoes precision grinding followed by a high-hardness hard chrome plating process. This ensures that the steel bars maintain dimensional stability, smooth operation, and exceptional service life even under prolonged, high-load conditions.

Our hard chrome plated steel bars enhance equipment performance and reliability:

• High Hardness Chrome Plating (HV800–1000): Provides more durable wear resistance.
• Ultra-Low Friction Surface: Ensures smoother operation and lower energy consumption.
• Excellent Corrosion Resistance: Suitable for a wide range of harsh industrial environments.
• High Dimensional Stability: Reduces the risks of oil leakage, jamming, and maintenance costs.
• Consistent Quality: Reliable batch-to-batch stability for long-term implementation.

Our products provide long-term service in:

• Hydraulic Cylinders & Pneumatic Systems
• Construction Machinery & Heavy Equipment
• Automation & Smart Manufacturing Equipment
• Plastic Injection, Die-Casting & Molding Machines
• Printing, Woodworking & Metalworking Machinery
• Energy, Marine & Various Industrial Equipment

Every steel bar undergoes a rigorous quality control process:

1. Strict Material Selection & Precision Turning: Utilizing premium steel as the base material.
2. High-Precision Grinding: Ensuring consistent dimensions across all units.
3. Professional Pre-treatment: Enhancing the adhesion of the plating layer.
4. Hard Chrome Plating: Precisely controlling the thickness of the hard chrome layer.
5. Post-Plating Grinding & Polishing: Achieving a smooth surface finish and precise diameter.
6. Comprehensive Inspection: Ensuring stable quality for final shipment.

We provide a complete range of industry-standard specifications to meet diverse requirements:

• Diameter Range: Ø6 mm to Ø100 mm
• Length: Available in both standard and custom lengths
• Tolerance Classes: ISO h8, h7, f7, f8
• Surface Roughness: Ra 0.2–0.5 μm (customizable upon request)

From standard applications to high-precision requirements, we provide everything you need in one place.

Hard Chrome Plating: Performance Beyond Durability

Hard chrome plating is more than just a protective layer; it is the key to operational efficiency:

• Significantly reduces wear and friction
• Enhances overall equipment performance
• Extends the service life of individual components and the entire machine
• Maintains high precision even during long-term operation

Yes, we focus on solving on-site challenges by providing comprehensive customization services:

• Dimensional Flexibility: Flexible adjustment of sizes, tolerances, and lengths.

• Custom Plating: Chrome thickness configured based on specific application requirements.

• Precision Specifications: Designated materials, surface roughness, and straightness.

• Scalable Production: Capable of handling both small-scale pilot runs and mass production.

As long as you provide the requirements, we can deliver the solution.

Regular cleaning with non-abrasive materials and proper lubrication helps maintain the surface quality and prolong the lifespan of the bars.
