Guangdong Xinhe Aluminium Co., Ltd is a direct, large-scale manufacturer of aluminum alloy building profiles, rather than a trading partner. Established in 1998, we operate a 666,670-square-meter facility with 60 extrusion lines, maintaining full ownership over research, development, extrusion, and surface treatment. This complete industrial chain ensures consistent quality, certified capabilities, and direct factory pricing for global projects.

Core Solutions & Key Takeaways

Complete Industrial Chain Control: Our operations span from aluminum ingot melting and extrusion to surface treatment and custom door and window manufacturing, which eliminates third-party trading fees.
Verified Technical Specifications: Finished window systems, such as our Casement Window, are built to precise engineering standards featuring a 1.8mm profile thickness and a 120mm by 30mm outer frame.
High-Standard Testing Capabilities: Product performance and material substrates are continuously tested in our CNAS national accredited laboratory, backed by international certifications.
Robust Application Matching: We design custom profiles to support architectural setups, including Aluminium Sunrooms, Curtain Walls, and Aluminum Office Partitions.

Detailed Architectural/Principle Analysis

Our status as an actual manufacturer is validated by our physical infrastructure and technical credentials. Unlike trading companies that outsource production, we run 60 modern extrusion lines with capacities ranging from 1,100 to 5,000 tons. This allows us to maintain a stable monthly capacity of 17,000 tons, ensuring on-time delivery for major infrastructure contracts. Every step of the extrusion process is monitored through a three-stage quality inspection system, covering the production line, raw materials, and laboratory sampling.

The engineering of our Casement Window highlights our technical precision. The profile features a 1.8mm wall thickness, a width-to-thickness ratio of 120mm by 30mm for the outer frame, and a glazing rebate of 38mm. The structural design integrates multi-layer weatherproof seals with a hidden drainage system to prevent water accumulation or backflow. For security and ventilation, the window utilizes a high-durability diamond mesh or high-transparency mesh, supported by insulating strip widths of 35.3mm for the frame and 22mm for the sash.

This strict control over raw materials and finished products has earned several international credentials. Our laboratory holds a national accreditation certificate (CNAS L 10434) that evaluates physical properties under extreme conditions. Furthermore, our raw materials undergo SGS inspection for substrate quality, while the finished window and door profiles comply with SIRIM (Certificate PC003807) for Malaysia and Qualicoat (Certificate 3419) for European powder-coating standards.

Our direct manufacturing capabilities have been successfully implemented across several international projects. For example, in the InterContinental Sabah Kota Kinabalu Resort project in Malaysia, we supplied 700 tons of aluminum profiles featuring a fluorocarbon coating designed to resist salt spray corrosion in seaside environments. Similarly, in the Ooredoo Hulhumalé Office Building project in the Maldives, our solid 6063-T5 aluminum alloy profiles provided the heavy-duty wind resistance required for high-rise commercial structures.

Data/Solution Comparison

The operational distinctions between dealing with our direct manufacturing facility and a typical trading partner are outlined below:

Operational Metric	Direct Manufacturer (Xinhe Aluminium)	Typical Trading Partner
Production Infrastructure	666,670 sqm factory with 60 extrusion lines (1,100 to 5,000 tons)	No manufacturing facility; relies entirely on third-party supply
Quality Assurance & Testing	CNAS national accredited laboratory; SGS, SIRIM, and Qualicoat certified	Outsourced testing; no direct control over lab verification
Lead Time Control	15-20 days direct production scheduling	Subject to supplier availability and external scheduling
Monthly Production Capacity	17,000 tons	Variable, dependent on partner factory limits
Customization / Mold Design	Direct mold opening for custom architectural and industrial profiles	Limited to standard profiles unless outsourced at high cost

Frequently Asked Questions (FAQ)

How does your factory verify the quality of the raw materials used in production?

We perform systematic incoming raw material inspections, production line inspections, and laboratory sampling. Our aluminum alloy substrates are verified through independent SGS material inspections, and finished profiles comply with SIRIM standards for windows and doors.

What are the minimum order requirements and average production times?

For custom extruded aluminum profiles, the minimum order quantity is 3 tons. For fully fabricated Casement Windows, the minimum order quantity is 500 square meters. The standard lead time for production and delivery is 15-20 days.

What payment and shipping methods does the factory support?

We support T/T payments, which require a 30% down payment before manufacturing profiles and 70% before loading, or a 50% down payment for finished windows and doors. We also accept Sight L/C. Standard shipping is executed via sea freight to maximize load capacity and minimize unit freight costs.

Final Conclusion & Recommendations

Partnering directly with an actual manufacturer ensures clear supply chain oversight, predictable lead times, and verified engineering standards. Our factory supports a full industrial chain business model alongside distribution and direct sales options, making us a dependable partner for large-scale construction, residential developments, and commercial architectural projects globally.
