Powder Coated Aluminum Profile
The Powder Coated Aluminum Profile is manufactured by Shanghai Huishuo Aluminum Industry Technology Co., Ltd, a China based industrial aluminum profile manufacturer operating three production bases in Shanghai, Anhui and Jiangsu covering approximately 30000 square meters. The profile surface is finished through electrostatic powder application followed by a curing stage, producing a coated layer used across outdoor structures, curtain wall systems, furniture frames and solar mounting components. Production combines extrusion, custom mold making, CNC machining, powder coating and assembly within a single supply chain.
Coating Process Stages
Powder coating is applied through an electrostatic process followed by a curing stage that fuses the powder into a continuous surface layer.
Core Advantages
- Coating Thickness Control Film thickness is controlled during electrostatic application and monitored after curing to meet the specified coating range.
- Wide Color Range Powder coating supports a broad range of RAL color references applied to custom profile orders.
- Integrated Mold and Coating Line Custom mold making, extrusion and coating are carried out within facilities operated by Huishuo Aluminum Industry.
- Post Coating CNC Processing Drilling, cutting and assembly operations are arranged around the coating stage to protect the finished surface.
Why Powder Coating Is Specified for Outdoor Profiles
Powder coating forms a continuous polymer film across the profile surface without the use of a liquid solvent carrier, which supports a consistent coating thickness across long profile lengths used in outdoor and architectural applications.

Application Scenarios
Curtain Wall Systems
Powder coated profiles are used in building facade frames where surface color and weather exposure are both specified.
Solar Mounting Structures
Support frames for solar panel installations use coated profiles for outdoor surface protection across long service periods.
Furniture and Fixtures
Frame components for furniture and display fixtures use powder coating for color matching across a product line.
Fencing and Railing Systems
Structural sections for fencing and railing systems use coated profiles for surface consistency across outdoor installations.
Considerations Before Ordering
Coating film thickness and color reference should be confirmed at the drawing stage, since powder coating parameters are adjusted according to the specified RAL color and target film thickness. Profiles coated in separate production runs may show minor variation in gloss level, so components used together in a single visible installation should be coated within the same batch.
Frequently Asked Questions
What type of powder is used for the coating
Profiles are coated using polyester based powder applied through an electrostatic spray process, which is a common coating type for outdoor aluminum profiles.
What color options are available
Coating is available in custom RAL color references, selected according to the color specification provided with the customer drawing.
What is the typical coating film thickness
Standard coating film thickness ranges from 60 to 120 micrometers, measured after the curing stage of the coating process.
Can custom profile shapes be powder coated
Custom mold making supports special cross sections, which are then processed through the same powder coating line used for standard profile shapes.
