The Ultimate Guide to Electrolytic Coated Aluminium Profiles: Features, Grades, and Applications
When it comes to choosing reliable, durable, and visually appealing materials for architectural and industrial projects, Electrolytic Coated Aluminium Profiles stand out as a top-performing solution. Combining advanced surface treatment with excellent corrosion resistance, these profiles are ideal for long-term use in even the harshest environments.
In this guide, we will walk you through the key features, coating grades, and practical applications of electrolytic coated aluminium profiles—based on real industry standards and advanced manufacturing practices, like those employed at Jiangxi KaiMeiDa Aluminum, a leading aluminium profile manufacturer in China.
1. What Are Electrolytic Coated Aluminium Profiles?
Electrolytic coated aluminium profiles are aluminium alloy extrusions that undergo a multi-layer surface treatment, combining anodic oxidation, electrophoretic coating, or powder coating to create a protective and decorative finish.
At Jiangxi KaiMeiDa, we use high-grade industrial aluminium (YS67-93) and apply coatings in compliance with national standard GB5237.3-2008, ensuring consistent quality and long-term performance. These profiles are suitable for doors, windows, curtain walls, office partitions, and various industrial frameworks.
2. Key Features That Set Them Apart
Electrolytic coated aluminium profiles offer a wide range of performance advantages that exceed traditional metals or untreated aluminium:
-
Corrosion Resistance: The composite coating layer effectively blocks erosion from acids, alkalis, and salt spray, achieving a corrosion resistance level of ≥9.5 grade.
-
Excellent Adhesion: Coating adhesion is rated at 0 grade, which is the highest level, preventing peeling or flaking under extreme conditions.
-
High Hardness: Surface hardness reaches ≥3H, making the profile resistant to scratches and surface damage.
-
Smooth Surface Finish: The texture is refined and consistent, offering a clean, modern appearance.
-
Multiple Finishes: Available in silver white, champagne, bronze, and sand-textured matte—ideal for aesthetic flexibility in design.
3. Understanding Coating Grades: Grade A vs. Grade B
Coating thickness and quality vary depending on performance requirements. At KaiMeiDa, we offer two standardized coating grades:
-
Grade A:
-
Oxide Layer: ≥10μm
-
Paint Film: ≥12μm
-
Total Coating Thickness: ≥21μm
-
Grade B:
-
Oxide Layer: ≥10μm
-
Paint Film: ≥7μm
-
Total Coating Thickness: ≥16μm
Grade A is typically recommended for exterior applications exposed to sun, rain, or pollution. Grade B is suitable for indoor or semi-exposed areas where durability is still critical but exposure levels are lower.
4. Real-World Applications Across Industries
Electrolytic coated aluminium profiles are used in a wide variety of industries due to their balance of durability, appearance, and workability.
-
Construction: Ideal for window and door frames, curtain walls, cladding systems, and sunshades.
-
Office Interiors: Used in modular partitions, frames, and display structures where aesthetics matter.
-
Industrial Equipment: Applied in mechanical frames, support structures, and protective enclosures.
-
Transportation: Suitable for vehicle bodies or components requiring lightweight and corrosion-resistant materials.
-
Customized Manufacturing: At KaiMeiDa, we support OEM/ODM orders based on customer drawings and specific performance requirements.
