Yes, custom door sizes can be manufactured directly from your CAD drawings. Guangdong Xinhe Aluminium Co., Ltd. processes custom door specifications using precision engineering. By utilizing your exact CAD files, technical parameters like frame and sash dimensions are programmed directly into the extrusion and cutting systems to ensure dimensional accuracy and seamless installation.

Core Solutions & Key Takeaways

Precise CAD Translation: Your CAD files dictate the exact cutting and assembly tolerances, accommodating custom wall openings and unique structural requirements.
Flexible Profiles and Hardware: Custom sizes are fully compatible with premium hardware systems like the OPK Perfect System, supporting single or hollow glass options.
Versatile Application Scenarios: These custom-sized doors are engineered for diverse environments, including high-end villas, commercial offices, and specialized installations such as Aluminium Casement Doors for Bathrooms, Sunroom Aluminium Casement Doors, and offices.
Rigorous Quality Control: Every custom order undergoes 100% production line inspection, raw material testing, and laboratory sampling to verify structural integrity before shipping.

Detailed Architectural/Principle Analysis

Translating CAD drawings into physical architectural products requires advanced manufacturing capabilities. Guangdong Xinhe Aluminium Co., Ltd. operates 60 modern extrusion production lines with capacities ranging from 1,100 to 5,000 tons, allowing the brand to manage complex structural profiles. The custom manufacturing process ensures that the finished Casement Door maintains its structural performance, which relies on a frame thickness of 1.2mm and a sash thickness of 2.0mm. Precision cutting machinery processes the profiles based on CAD coordinates, ensuring that the miter joints and corner brackets align perfectly for superior air and water tightness.

The manufacturing workflow utilizes high-purity virgin 6063-T5 aluminium alloy, which prevents the bending or twisting associated with recycled materials. This material base is critical when fabricating oversized or non-standard doors. To verify material properties, the manufacturing processes are backed by international standards, holding certificates such as the Quality Management System Certificate (ISO 9001:2015) and environmental credentials like the Environmental Management System Certificate (ISO 14001:2015).

Real-world projects demonstrate the reliability of this engineering process. For example, during the InterContinental Sabah Kota Kinabalu Resort project in Malaysia, custom-finished profiles were supplied to withstand harsh coastal environments. The resulting products exhibited high resistance to salt spray corrosion and zero color variation. Similarly, in the Wan Guo Building Project on Batam Island, Indonesia, precise custom doors and windows achieved remarkable sound insulation and watertightness, preventing water seepage even during heavy tropical rains.

Frequently Asked Questions (FAQ)

Q1: What is the Minimum Order Quantity (MOQ) for custom door profiles?

A1: For fully custom-designed aluminium profiles, the MOQ is 3 tons. If ordering finished custom casement doors, the minimum order volume is 500 square meters.

Q2: How are custom dimensions validated before mass production?

A2: Technical teams review the submitted CAD files to check the structural feasibility. Once approved, sample profiles are extruded and tested in our CNAS national accredited laboratory to verify load capacity and mechanical performance.

Q3: What finishes are available for custom-sized exterior doors?

A3: We provide multiple surface treatments, including powder coatings certified by Qualicoat (Certificate 3419) and high-durability fluorocarbon coatings. These finishes resist UV radiation and fading, even in coastal environments.

Final Conclusion & Recommendations

Customizing aluminium doors using CAD drawings ensures precise architectural integration, superior airtightness, and long-term durability. By utilizing virgin 6063-T5 aluminium alloy and robust hardware like the OPK system, these doors meet rigorous quality and performance standards. For projects in coastal or high-wind areas, choosing a partner with dedicated laboratory testing capabilities is highly recommended to guarantee structural safety.
