Custom Powder Coated Aluminum Window & Door Frame Profiles

Our 6063-T5 Aluminum Window & Door Profiles are engineered through advanced hot extrusion and finished with premium powder coating. Designed for seamless integration into residential and commercial building systems, these profiles balance structural integrity with aesthetic versatility.

With a strictly controlled Webster hardness of 10±2HW, our profiles offer the perfect “sweet spot” for mechanical strength and ease of fabrication (sawing, punching, and assembly).

Technical Specifications

Why Choose Our Aluminum Frame Profiles?

1. Optimized Mechanical Performance

By maintaining a hardness of 10±2HW, we ensure the frames are rigid enough to support heavy glass loads while remaining ductile enough to prevent cracking during high-speed punching or corner-crimping processes.

2. Superior Weatherproof Coating

We utilize world-class powder brands (such as AkzoNobel and Tiger).

• Adhesion: Grade 0 (ISO Standard).
• Salt Spray Test: ≥1000 hours without corrosion.
• UV Resistance: 10+ years of color retention without chalking.

3. Precision Engineering & Tight Tolerances

Critical assembly dimensions are controlled within ±0.2mm. This precision eliminates gaps and rattling after assembly, ensuring your finished windows meet high energy-efficiency and soundproofing standards.

4. Total Customization (OEM/ODM)

We accept .DWG, .STEP, and .PDF files. Our engineering team reviews every mold design to ensure manufacturability, reducing the risk of “design-to-production” discrepancies.

5. Traceable Quality Assurance

From raw aluminum ingot spectral analysis to final film thickness and color difference ($\Delta E \leq 1.0$) testing, every batch is logged and delivered with a comprehensive Quality Inspection Report.

Common Applications

• Residential: High-end thermal break casement windows and tilt-and-turn systems.
• Commercial: Storefront entries, curtain wall framing, and office partitions.
• Outdoor: Sunroom structural supports and heavy-duty patio door tracks.

Q&A

Q: Why use 6063-T5 instead of 6061 for window frames?

A: 6063 is the “architectural alloy.” It allows for more complex, thin-walled multi-cavity designs and provides a much smoother surface finish, which is essential for high-quality powder coating. 6061 is stronger but harder to extrude into intricate shapes and often leaves visible surface streaks.

Q: Is 10±2HW hardness really necessary?

A: Yes. Below 8HW, the profile is too soft and may deform during assembly. Above 14HW, the metal becomes brittle and prone to cracking when you punch holes or crimp corners. Our range ensures the best balance for longevity and workability.

Q: How do you ensure color consistency between different orders?

A: We archive a “Master Sample” and record the specific technical parameters (oven temperature, line speed, and powder batch) for every client. Every repeat order is matched against the physical master sample to ensure qualified quality

Q: Can you provide finished components?

A: Absolutely. We offer “ready-to-assemble” services including precision mitre cutting, CNC machining, and drainage hole punching. This reduces your factory scrap rate and labor costs.
