Core Product Features | Designed for Sliding Door Performance

Sliding door components are manufactured from high-quality stainless steel, combined with advanced surface treatments such as passivation, zinc plating, zinc-nickel alloy plating, and chrome plating.

Key Advantages

• High-strength stainless steel base ensures resistance to deformation and fracture, maintaining structural stability during operation.

• Multiple surface treatment options enhance corrosion resistance, wear resistance, and anti-rust performance for indoor and outdoor environments.

• Precision machining ensures accurate fit and minimal clearance, reducing sliding resistance and improving user experience.

• Smooth, burr-free surfaces prevent scratching and wear on door components, extending overall service life.

• Excellent machinability allows for precise forming of complex parts such as roller shafts and positioning sleeves.

• Fully compatible with various sliding door assembly requirements.

These features make our stainless steel turnings ideal for high-performance sliding systems.

Precision Manufacturing | CNC Machining for Stability and Smooth Motion

Optimized Machining Process

Machining parameters are specifically optimized for sliding performance. One-piece forming enhances structural strength while ensuring smooth surface quality, effectively reducing friction during operation.

Full Quality Control System

• Raw material composition inspection

• First article verification

• High-frequency in-process inspection

• Profile projector

• Geometric tolerance inspection

• Surface treatment quality inspection

• Sliding performance testing

Each stage is 100% inspected to eliminate defects at the source and ensure consistent product quality.

Standardized Surface Treatment

Passivation, zinc plating, zinc-nickel plating, and chrome plating are all performed under standardized processes. Parameters are strictly controlled to ensure uniform coating thickness, strong adhesion, and consistent corrosion and wear resistance across batches.

Global Order Support

We support:

• Neutral packaging and custom branded packaging

• Internal anti-scratch and anti-impact protection

• Compliance with international transportation standards

Lead times:

• 7–15 days for small batches

• 15–30 days for mass production

Dedicated one-to-one service ensures efficient support for global procurement of stainless steel turnings.

Core Performance

Dimensional Accuracy

• Diameter / hole tolerance: ±0.02 mm

• Length tolerance: ±0.03 mm

• Wall thickness tolerance: ±0.01 mm

Designed to precisely match rollers, guide rails, and door assemblies in compact installation spaces.

Geometric Accuracy

• Concentricity ≤0.02 mm

• Roundness ≤0.01 mm

• Perpendicularity ≤0.03 mm

• Flatness ≤0.02 mm

Ensures smooth rotation of components such as roller shafts, preventing vibration, noise, or jamming.

Sliding Performance & Fit

The contact surfaces of the stainless steel turnings are finely finished with low friction resistance, ensuring smooth and stable door operation. The structural design aligns with sliding door mechanics and can withstand up to 500 kg of push-pull force without deformation or loosening.

Corrosion & Wear Resistance

After professional surface treatment:

• Atmospheric corrosion resistance ≥ 100 hours

• Resistant to moisture, indoor/outdoor humidity, and industrial dust

Provides excellent wear resistance and long-term durability, even in outdoor environments.
