Certified Aluminium Window Profiles – Tested & Compliant | Shengxin

Certified Aluminium Window Profiles give you more than a physical product — they give you documented proof of performance. For architects, specifiers, and fabricators working on projects that require building regulation approval, the difference between a certified profile and an uncertified one is the difference between a smooth submission and a stalled project. Our certified profiles are tested, documented, and traceable, so the performance numbers you submit are the performance numbers the building gets.

Every certified profile order includes a complete documentation package: EN 14351-1 window performance data covering air permeability, water tightness, and wind load resistance; Qualanod certification for anodized finishes or AAMA 2604 for powder coating; mill certificates showing alloy composition and mechanical properties; and EN ISO 10077-2 thermal simulation reports where applicable. Full batch traceability links each profile back to its original extrusion run, so any quality question can be answered with data, not assumption.

Shengxin has over 30 years of aluminium extrusion expertise and operates an in-house quality laboratory for ongoing verification. We extrude, finish, and test under one roof, meaning the profile you specify is the profile you receive — manufactured, documented, and delivered by a single accountable partner. For thermal performance certification, see our thermal break window profiles. For fully bespoke sections, explore our custom profile development service.

Features & Benefits

• Documented compliance package: Every certified order includes the test reports, certificates, and mill documentation needed for building regulation submission and customer warranty support.
• Verified window performance: Air permeability, water tightness, and wind load resistance tested to EN 14351-1 — the standard reference for window performance across international markets.
• Certified surface finishes: Anodized finishes are Qualanod certified; powder coated finishes meet AAMA 2604. Both provide documented colour retention, chalk resistance, and corrosion protection.
• Full batch traceability: Every certified profile can be traced back to its alloy composition and extrusion run, supporting quality audits and warranty investigations.
• Thermal performance data: EN ISO 10077-2 simulation reports provide Uf values for your specific profile geometry and glazing combination, supporting energy code compliance.
• In-house quality laboratory: Ongoing testing ensures our certified profiles continue to meet the same standards batch after batch, not just when certification was first achieved.

Certification & Compliance Documentation

The documentation provided with each certified order covers the key compliance areas required by building regulations and project specifications.

All documents are provided in PDF format, suitable for direct submission to building authorities or inclusion in project submittal packages.

Technical Specifications

For interior coordination, we also manufacture anodized aluminum profile for cabinet door sections with the same certified anodizing quality, ensuring finish consistency throughout the building.

Who Needs Certified Aluminium Window Profiles?

• Architects and specifiers: When your drawings call for specific performance values, certified profiles provide the documented proof that supports your specification and protects your professional liability.
• Fabricators serving regulated markets: Building regulations in many regions require test documentation for window products. Certified profiles give you the paperwork to support your product submissions.
• Developers and contractors: For commercial and public sector projects, certified materials are often a contractual requirement. Having the documentation upfront avoids delays at approval stage.
• Export-oriented businesses: When selling into international markets with different compliance requirements, certified profiles help you demonstrate conformity to local standards.
• Quality-focused residential builders: For premium homes where performance claims must be verifiable, certified profiles provide the evidence that supports your marketing and warranty commitments.

Customisation & Certification Options

Why Choose Shengxin for Certified Profiles?

Certification is only as valuable as the manufacturing consistency behind it. At Shengxin, we do not simply hold certificates — we maintain the quality systems that those certificates represent. Our in-house laboratory continuously verifies extrusion tolerances, finish quality, and thermal performance, ensuring the profiles we deliver match the documented standards batch after batch. With over 30 years of manufacturing history and an ISO 9001 quality management system, we provide certification you can rely on long-term.

Certified Aluminium Window Profiles FAQ

Custom Certified Profile Solutions

If your project requires custom profile geometry with full certification documentation, Shengxin's certified extrusion service can develop, test, and manufacture profiles to your exact drawings, delivered with complete compliance packages.

How It Works:

1. Send your drawing — 2D PDF/DWG or 3D STEP/IGES file showing the profile geometry and certification requirements.
2. Our engineers review — we assess extrudability and identify the applicable testing standards.
3. Receive a quotation — including die cost, testing costs, unit price, and lead time.
4. Approve a sample — we extrude and finish a trial section, then arrange the required testing.
5. Full production — certified profiles delivered with complete documentation.

⚠️ Important Note: All profile images and dimensional drawings on this page are for reference only. Final dimensions, test results, and certification documentation will be confirmed based on your approved production drawings and testing programme. Please contact our engineering team to discuss your specific certification 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 additional testing must be scheduled. Your dedicated project engineer will provide updated timelines at each stage, and final delivery dates will be confirmed in your order confirmation.
