Dongguan Cellar Aluminum Co., Ltd. is a professional manufacturer specializing in aluminum material processing and supply, positioned as a Aluminium Plate Manufacturer | Aluminium Sheet & Industrial Metal Material Supplier. Established in 2011 in Dongguan, China, our company has evolved from a specialized workshop into a global powerhouse for high-quality aluminum products.
With over a decade of expertise, we serve critical sectors including construction, transportation, machinery manufacturing, packaging, and electronics. Our modern production facilities are equipped with automated rolling lines and precision cutting systems, ensuring every Aluminium Thermal Break Profile meets international standards for structural integrity and thermal efficiency.
The global demand for Aluminium Thermal Break Profiles is currently witnessing an unprecedented surge, driven primarily by stringent carbon-neutrality goals and the rising cost of energy. In modern architecture, the "Thermal Bridge" effect—where heat escapes through high-conductivity metal frames—is a major challenge. Thermal break technology solves this by inserting a low-conductivity polyamide strip between the inner and outer aluminum profiles.
In Europe and North America, building codes now mandate specific U-values that are nearly impossible to achieve without advanced thermal break systems. This has shifted the industrial focus from simple aluminum extrusions to complex, multi-cavity thermal profiles that offer superior U-factor performance. As a leading manufacturer in China, we are at the forefront of this transition, supplying high-precision profiles that help global contractors meet "Passive House" standards.
Reduces indoor heating and cooling costs by up to 40% compared to standard aluminum frames.
Prevents the formation of frost or water droplets on the interior surface of the frame.
The thermal barrier strip also acts as a sound dampener, significantly reducing urban noise pollution.
As a technology-driven supplier, we monitor several key trends shaping the industry:
Our R&D team continuously explores the application of PA66GF25 (Polyamide 66 reinforced with 25% glass fiber) as the thermal barrier material of choice. This material mimics the coefficient of linear expansion of aluminum, ensuring that the profile remains stable under extreme temperature fluctuations—from the scorching heat of the Middle East to the freezing winters of Northern Europe.
Located in the industrial hub of Dongguan, we provide a strategic logistical advantage. Our factory offers a full-chain solution from raw material billet casting to complex surface treatments.
✓ Experience: Operating since 2011 with deep material science knowledge.
✓ Customization: We offer comprehensive OEM/ODM services for custom architectural shapes.
✓ Quality Control: Every batch undergoes spectral analysis and tensile testing.
✓ Scale: High-volume capacity to support large-scale government and commercial projects.
Global procurement teams from diverse industries seek our Aluminium Thermal Break Profiles for various localized needs. In the Residential Sector, our profiles are used for high-end windows and sliding doors. In the Commercial Sector, they are the backbone of energy-efficient curtain walls for skyscrapers.
Key Application Scenarios:
Used to keep solar heat out, reducing air conditioning load in regions like Southeast Asia and the Middle East.
Keeping interior heat in, preventing energy loss in regions like Scandinavia, Canada, and Russia.
Ideal for hotels and hospitals near airports or highways requiring superior DB reduction.
Our export network spans Southeast Asia, the Middle East, Europe, and South America. We understand the specific regional certifications required, such as CE marking for Europe or AAMA standards for the North American market. By partnering with us, you gain access to a reliable supply chain that prioritizes material performance and cost-effectiveness.
To ensure our role as a reliable China Best Aluminium Thermal Break Profiles Supplier, we implement a rigorous quality management system. Each extrusion is checked for dimensional accuracy, surface finish, and the mechanical strength of the thermal break bond (pull-out strength and shear strength). We understand that in the building industry, material failure is not an option.
Our logistics team specializes in sea and air freight, ensuring that large-scale profile shipments arrive at your project site or warehouse without damage. We use customized protective packaging, including PE film, waterproof kraft paper, and reinforced wooden crates. Whether you are a distributor in the UAE or a construction firm in Australia, we provide the transparency and reliability you need to keep your projects on schedule.
