What do I need to send to start a custom aluminum window or door order?

Architectural drawings, a BOQ or simply your opening sizes are enough to start. Our engineers select the profile series, glass and hardware, then issue shop drawings for your approval before production begins.

Can I check quality before placing a bulk order?

Yes. You can order corner samples or a full-size sample window to verify finish, hardware operation, sealing and build quality before mass production.

Which certifications and test results are available?

Our 76M tilt and turn system holds an AS 2047 StandardsMark Licence (SMK41686), our quality management is certified to ISO 9001:2015, and CE conformity is available. Complete national test-center reports can be provided on request, and products can be configured for NFRC, CE or AS 2047 target markets.

What is the difference between your OEM and ODM service?

With OEM, you supply the design and specifications and we manufacture to your exact standard with IP protection. With ODM, you choose from our tested product library and we apply your logo, labels and packaging for a faster, lower-cost launch.

Which markets do you ship to and how are windows packed?

We ship to the USA, Europe, the Middle East, Central Asia and Australia. Every unit is protected with corner guards and film wrap and loaded to prevent movement during sea freight.

What glass and finish options are available?

Options include Low-E, argon-filled and laminated insulating glass, thermal break profiles with PA66 strips, and PVDF, powder-coated, anodized or wood-grain finishes in custom colors.

Engineering Architecture of Modern Aluminium Front Doors

An in-depth whitepaper on raw materials, thermal break dynamics, structural metallurgy, and surface resilience.

1. Profile Metallurgy & Alloy Selection

Aluminium entry doors designed for high-traffic, harsh-weather exterior environments rely strictly on 6063-T5 or 6060-T66 architectural grade extrusion alloys. The T5 heat treatment process ensures a minimum tensile strength of 160 MPa and yield strength of 110 MPa, providing the flexural rigidity required to support heavy multi-layer toughened safety glass and oversized pivot hinges without sag or frame distortion over decades of operation.

2. Multi-Cavity Polyamide Thermal Barrier (PA66 GF25)

Standard aluminium profiles suffer from high thermal conductivity (approx. 200 W/m·K). Our engineered front doors incorporate 24mm to 34mm multi-cavity thermal break strips reinforced with 25% fiberglass (PA66 GF25). This lowers the frame thermal conductivity to under 0.3 W/m·K. Combined with polyurethane foam cavity filling, heat transfer via conduction is virtually eliminated, keeping interior spaces insulated against sub-zero winters or desert heat.

Advanced Surface Finishing Metallurgy

To resist salt-spray corrosion in coastal export markets (such as Australia, the Caribbean, and coastal North America), our extrusions undergo specialized surface treatments complying with AAMA 2605 and Qualicoat Class 2 standards:

PVDF (Fluorocarbon) Coatings: 3-coat system cured at high temperatures, offering 25+ years of UV color retention and chemical resistance against acid rain and atmospheric pollutants.
Architectural Anodizing (25 Micron): Electro-chemically sealed oxide layers that create an scratch-resistant metallic surface immune to chalking or peeling.
3D Electro-Transfer Wood Grain: Combining natural timber aesthetic warm textures with structural aluminium non-combustibility and zero termite risk.

Future Procurement & Sourcing Trends (2026–2030)

Key architectural directions reshaping global commercial and luxury residential entry door specifications.

1. Large-Format Oversized Pivot Doors

Architectural demand is transitioning rapidly from standard swing doors to grand pivot entrance systems reaching heights of up to 4.5 meters and widths of 2.2 meters. These systems utilize heavy-duty hydraulic floor pivots with 500kg+ load capacities, soft-close dampeners, and multi-point perimeter locking hooks for effortless fingertip operation.

2. Smart Access & IoT Hardware Integration

Front entry doors are shifting from purely mechanical security to integrated smart building hubs. B2B buyers now mandate factory-concealed wiring raceways to house biometric 3D facial recognition scanners, hidden motor-driven multi-point locks, invisible keypad handles, and remote smartphone control modules natively embedded into the aluminium profiles.

3. Decarbonization & Embodied Carbon Compliance

Driven by EU Green Deal policies and global LEED building requirements, leading developers prioritize suppliers utilizing low-carbon primary aluminium smelted with renewable hydro-energy. Our manufacturing process emphasizes closed-loop scrap recycling and transparent Environmental Product Declarations (EPD).

Frequently Asked Questions by Global Importers & Specifiers

Direct technical and commercial answers to address procurement risk, order logistics, and quality assurance.

What engineering documentation do you require to generate an accurate OEM quote?

To provide a precise technical proposal and commercial breakdown, we accept architectural CAD elevation files (.DWG, .DXF), REVIT BIM models, or a structured Bill of Quantities (BOQ) with rough opening dimensions. Our engineering team selects appropriate profile wall thicknesses, thermal break depth, and wind-load glass configurations, returning detailed shop drawings and static calculation reports for buyer approval within 24 to 48 hours.

How do you verify corner joint structural integrity and water tightness before export?

We employ dual-component structural corner adhesives combined with cast aluminium corner cleats precision-crimped under pneumatic pressure. Select premium lines feature digital laser cold-welding, creating a solid unified joint. Every batch undergoes 100% corner squareness check (tolerance within ±0.2mm) and hydrostatic pressure testing to eliminate joint water leakage risks during extreme storm conditions.

What glass configurations are available for impact-resistant and energy-efficient entrance doors?

We process insulated glass units (IGU) in-house. Options include double or triple toughened safety glass with Low-E coatings (Single, Double, or Triple Silver), warm-edge spacers, and 90%+ Argon gas fill. For hurricane zones or high-security commercial applications, we supply laminated SGP (SentryGlas®) impact glass capable of passing Florida Miami-Dade large missile impact tests.

What is the difference between your OEM and ODM manufacturing tracks?

OEM Service: Custom manufacturing executed strictly according to your proprietary profile dies, hardware specifications, and private design rights under strict NDA protection.
ODM Service: Selecting pre-tested, fully certified systems directly from our 219+ patent library (e.g., our 76M system). We apply your custom branding, hardware finishes, customized packaging, and market-specific certification labeling for accelerated product launches.

How are oversized glass entry doors packaged to guarantee zero damage during ocean freight?

Export protection is critical. All door frames and glazed sashes are individually wrapped in 5-layer protective shrink film, fitted with custom rubber edge guards, and packed inside fully enclosed fumigation-free plywood crates. Crates are engineered with internal steel bracing and floor-cleat tie-downs to ensure zero shift inside 20GP or 40HQ sea freight containers.

Can you integrate third-party hardware brands such as Siegenia, Hoppe, or Sobinco?

Yes. While we supply premium factory-standard multipoint locking systems and heavy-duty concealed hinges, our extrusion profiles are engineered with standard European C-groove and K-groove hardware cavities. This allows seamless factory pre-drilling and integration of European hardware brands including Siegenia, Hoppe, Sobinco, Cisa, or GU depending on project specification demands.

What is your standard production lead time for full container orders?

Upon shop drawing sign-off and deposit confirmation, standard production lead time for custom extrusion color and fabrication is 25 to 35 calendar days. For sample orders or standard warehouse inventory profile series, dispatch can be completed within 14 days.
