Anodised Aluminium Window Profiles – Durable Finish Extrusions | Shengxin

Anodised Aluminium Window Profiles offer a finish that no other surface treatment can match. Anodizing grows a transparent oxide layer directly from the aluminium itself, creating a hard, durable surface with a distinctive metallic sheen. The result is a window frame that looks premium, feels smooth, and resists corrosion for decades — without the risk of peeling, flaking, or fading that painted finishes carry. For architects and homeowners who want the natural beauty of aluminium with proven long-term performance, anodised profiles are the definitive choice.

The anodizing process enhances the inherent corrosion resistance of 6063-T5 aluminium. The oxide layer is integral to the metal, so it cannot delaminate like a coating. Scratches do not expose a different material beneath; the oxide simply reforms. For coastal properties, we recommend AA20 or AA25 film thickness, which provides excellent salt spray resistance. For interior or sheltered applications, AA15 is often sufficient. All our anodizing is performed in-house and certified to Qualanod standards, with film thickness and sealing quality verified on every batch.

Shengxin has over 30 years of aluminium extrusion expertise. We extrude, anodize, and finish these profiles under one roof, giving you a single accountable partner for the entire process. For custom geometry, our custom extrusion service can produce the exact profile you need. If you also require thermal insulation, see our thermal break window profiles, which can be supplied with an anodized finish.

Features & Benefits

• Integral anodized finish: The oxide layer is grown from the aluminium itself, forming a molecular bond that cannot peel or flake. This is the most durable decorative finish available for aluminium window profiles.
• Premium metallic appearance: The translucent oxide layer enhances the natural metallic look of aluminium. Choose from clear silver, black, bronze, or champagne tones for a distinctive architectural finish.
• Superior corrosion resistance: Sealed anodized surfaces withstand salt spray and coastal conditions exceptionally well. Film thicknesses up to AA25 provide protection for waterfront buildings.
• Hard and abrasion resistant: The anodic film has a hardness of 250–350 HV, providing excellent scratch resistance for years of daily use.
• UV stable and fade resistant: The anodized colour is unaffected by sunlight. It will not fade, yellow, or chalk, even after decades of outdoor exposure.
• Low maintenance: Anodized profiles never need painting or sealing. A simple wash with mild soap and water keeps them looking new.

Anodizing Grades & Performance

Select the anodizing grade that matches your project's exposure and performance requirements.

All anodizing is performed in-house with full Qualanod certification.

Technical Specifications

For interior applications, we also manufacture slim anodized standard-size cabinet door aluminum profile sections with the same anodized finish quality.

Applications of Anodised Aluminium Window Profiles

• Coastal and waterfront homes: The sealed anodized finish withstands salt spray exceptionally well, maintaining its appearance without the white corrosion that plagues other finishes.
• High-end residential projects: The premium metallic sheen of clear or bronze anodizing adds a sophisticated touch that architects and homeowners specify for luxury builds.
• Commercial and office buildings: Durable, low-maintenance anodized frames are ideal for office facades and storefronts where longevity and appearance are equally important.
• Heritage and renovation projects: Anodized finishes can be matched to existing metalwork on period buildings, offering a traditional look with modern aluminium performance.
• Interior feature windows and partitions: For interior glazing with a premium finish, anodized profiles provide a clean, metallic appearance that complements contemporary interiors.

Customisation & Supply Options

Why Choose Shengxin for Anodised Window Profiles?

Anodizing quality depends heavily on the surface condition of the aluminium before it enters the bath. At Shengxin, we extrude the profiles ourselves, which means we can control the grain structure and surface finish from the very beginning. This results in anodised window profiles with a uniform, flawless appearance that is difficult to achieve when anodizing is outsourced. Our 30+ years of extrusion expertise and in-house anodizing lines give you quality you can see.

Anodised Aluminium Window Profiles FAQ

Custom Anodised Window Profile Solutions

If your project requires a custom profile shape, a specific anodizing grade, or a unique colour, Shengxin's custom extrusion and anodizing service can produce profiles to your exact drawings, delivered with full quality documentation.

How It Works:

1. Send your drawing — 2D PDF/DWG or 3D STEP/IGES file showing the profile geometry and finish requirements.
2. Our engineers review — we assess extrudability and anodizing response, then suggest optimisations.
3. Receive a quotation — including die cost, anodizing grade, unit price, and lead time.
4. Approve a sample — we extrude and anodize a trial section for your approval.
5. Full production — consistent quality, delivered on schedule with full documentation.

⚠️ Important Note: All profile images and dimensional drawings on this page are for reference only. Final dimensions, anodizing grade, colour, and surface finish will be confirmed based on your approved production drawings. Please contact our engineering team to discuss your specific requirements before placing an order.

Please note: The production timelines discussed are typical estimates based on smooth design approvals and current scheduling. Actual lead times may be longer if design changes are required, multiple sample iterations are needed, or production capacity is temporarily at high demand. Your dedicated project engineer will provide updated timelines at each stage, and final delivery dates will be confirmed in your order confirmation.
