Example finished aluminum parts for global projects
A controlled finishing workflow helps ensure surface cleanliness, color consistency, coating adhesion, appearance quality, and safe packaging for custom aluminum parts.
01
Parts are cleaned, degreased and inspected before finishing. Sandblasting, chemical cleaning or other pre-treatment methods are used to improve adhesion and surface consistency.
02
Color samples, surface texture, gloss level and coating requirements are reviewed before batch finishing to better match project specifications.
03
Anodizing or powder coating is applied under controlled process conditions, including coating thickness, temperature, voltage or curing parameters.
04
Anodized parts can be dyed and sealed for color stability and corrosion resistance. Powder-coated parts are cured to form a durable protective finish.
05
Coating thickness, adhesion, color consistency and surface appearance are checked against drawings, samples or approved finishing requirements.
06
Finished parts are protected with PE film, foam inserts, interleaf paper or edge protectors to reduce surface damage during handling and export shipment.

End-to-end aluminum finishing solutions engineered for quality, speed, and long-term partnership.
We help review part material, surface condition, application environment, and appearance requirements to recommend suitable finishing options.
Color samples, gloss level, surface texture, and coating requirements can be confirmed before batch finishing to improve consistency.
We use protective film, foam, interleaf paper, and custom packaging methods to reduce scratches and surface damage during transport.
FAQ
Powder coating and Type III hard anodizing are both strong options for outdoor aluminum parts. Powder coating provides excellent color durability and UV resistance, while hard anodizing improves surface hardness and wear resistance. For coastal or marine environments, conversion coating with powder coating can provide stronger corrosion protection.
Yes. We can finish aluminum parts supplied by customers or other manufacturers. Please provide the material grade, current surface condition, drawings and finishing requirements so we can recommend the right pre-treatment and finishing process.
Type II anodizing creates a 5–25 μm oxide layer for decorative color, corrosion resistance and general aluminum protection. Type III hard anodizing creates a thicker 25–75 μm oxide layer for better wear resistance, surface hardness and durability in demanding applications.
Yes. We support RAL color matching, custom color samples and batch color verification. Please provide a RAL code, Pantone reference or physical sample so we can match the required appearance before production.
The right finish depends on corrosion resistance, wear resistance, color, surface texture, operating environment and cost requirements. Our team can recommend suitable options such as anodizing, powder coating, sandblasting, polishing, electrophoresis or conversion coating based on your application.
Batch QC includes visual inspection, coating thickness checks, adhesion testing and color verification based on the finish type and customer requirements. Inspection records or certificates of conformance can be provided for production projects.
