Anodized Aluminum Window & Door Frame Profiles

Premium 6063-T5 Custom Extrusions | In-House Anodizing Line | Superior Corrosion Resistance
Precision Engineered for Elite Architectural Systems
With an in-house, fully integrated anodizing production line, we provide window and door brands with unmatched film thickness control, color consistency, and premium metallic textures. From complex blueprint matching to large-scale project delivery, we ensure your frames withstand the elements while maintaining a high-end aesthetic.

Product Overview
Our 6063-T5 Anodized Aluminum Window & Door Profiles combine advanced hot-extrusion with a controlled electrochemical surface treatment. The anodizing process creates a dense, protective oxide layer that is integrated with the aluminum substrate—making it highly resistant to wear, scratches, and atmospheric corrosion.

With a standard film thickness of 10±2μm (upgradable up to 25μm) and a carefully maintained Webster hardness of 10±2HW, these profiles offer the ideal balance between structural longevity and efficient post-processing (cutting, punching, and crimping).

Product Core Advantages
1. Precise Film Thickness Control
Operating our own anodizing lines allows us to maintain a strict 10±2μm standard. For harsh environments, such as high-salinity coastal areas or humid regions, we can thicken the layer to 15–25μm to exponentially increase the profile’s lifespan against corrosion.

2. Perfect Balance of Strength & Workability
By controlling the hardness at 10±2HW, we ensure the frame remains rigid enough to hold heavy structural loads while preventing cracking or excessive tool wear during high-speed cutting, punching, or corner-crimping.

3. Premium Metallic Texture & Zero Peeling
Unlike powder coating, anodizing enhances and showcases the natural metallic grain of the aluminum substrate. The oxide layer will never peel, flake, or blister, ensuring full, uniform coverage even along sharp profile edges and intricate corners.

4. Tight Assembly Tolerances
Critical assembly and track dimension tolerances are strictly held within ±0.2mm. This precision engineering ensures perfectly tight corner joints and ultra-smooth sliding performance, eliminating rattles and post-installation service calls.

5. End-to-End Quality Traceability
Our rigorous quality control covers everything: raw billet spectral testing, extrusion parameters tracking, chemical tank analysis, and final testing for film thickness, color variance, and corrosion resistance. Every batch is shipped with a certified inspection report.

Common Applications
1).High-End Residential Windows: Casement and tilt-and-turn frames seeking a premium, modern metallic aesthetic.
2).Heavy-Duty Sliding Systems: Sliding door tracks that require high surface hardness and smooth, wear-resistant friction lanes.
3).Commercial Shopfronts & Partitions: Consistent, elegant storefront entrances and interior office glass framing.
4).Coastal & Marine Projects: Toughened architectural frameworks utilizing thickened anodized layers to resist salt-spray damage.

Frequently Asked Questions (FAQ)
Q1: How do I choose between Anodizing and Powder Coating?
A: Anodizing preserves the natural metallic grain, offers higher surface hardness, and cannot peel off, making it ideal for sleek, modern designs. Powder coating offers limitless color choices and high covering power. For coastal areas, both work beautifully, though anodizing should be ordered with a thickened film layer.

Q2: Is a 10μm film thickness enough? When should I consider thickening it?
A: The standard 10±2μm thickness is perfect for typical inland residential and commercial buildings. However, if your project is located within a coastal zone, high-humidity area, or industrial sector, we highly recommend upgrading to 15–25μm. This upgrades the salt spray resistance to over 1000 hours.

Q3: What anodized colors are available?
A: Our standard architectural palette includes Silver (Clear Anodized), Champagne, Bronze, and Black. While custom shades can be developed, the chemical composition of the 6063 alloy heavily impacts color consistency. We always provide physical color boards for approval before mass production.

Q4: Will the anodized finish fade over time?
A: The anodic film itself is a permanent inorganic layer that won’t fade. For coloration, we use an electrolytic coloring process (Champagne/Bronze) which offers exceptional UV resistance and will not fade under intense sunlight.

Q5: What are your capabilities regarding ultra-long profiles?
A: Our standard production length is 6 to 6.5 meters, but we can customize profiles up to 7 meters. For ultra-long orders, our team will verify our anodizing tank capacities and specialized shipping logstics before finalizing production.
