Professional Aluminum Surface Finishing

High-quality protective and decorative solutions for your aluminum extrusions.

High-Performance Surface Finishing Solutions

As a leading aluminum manufacturer in China, YuanZhong Technology Co., Limited provides a diverse range of finishing options designed to improve corrosion resistance, hardness, and aesthetic appeal. Whether you are working on 6063 architectural profiles or industrial components, we have the right solution.

Why Surface Treatment is Essential

Untreated aluminum can oxidize over time. Proper finishing can extend product life by a decade and ensure compliance with international quality standards. Our advanced facility ensures consistent color matching and thickness across large production batches.

Premium Aluminum Finishing Options

Anodizing (Clear & Color)

The Process: An electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish.

Best For: Sliding shower enclosures and electronic housings.

Powder Coating

The Process: Applying a dry powder through an electrostatic process, followed by heat curing to form a hard “skin”.

Best For: Outdoor architectural structures requiring custom RAL colors and UV protection.

Chemical Conversion

The Process: Also known as chromate coating, it provides an excellent base for paint and improves electrical conductivity.

Best For: Internal industrial parts and aerospace components made from 7075 aluminum alloys.
