Dongguan Cellar Aluminum Co., Ltd. is a premier manufacturer specializing in advanced aluminum material processing. As a top-tier Aluminium Plate Manufacturer and Solar Frame Exporter, we bridge the gap between raw material excellence and industrial application. Established in 2011, our journey began in the heart of Dongguan's manufacturing hub, evolving from a precision workshop into a global leader in aluminum extrusion and surface treatment.
By 2016, our facility integrated automated rolling lines and state-of-the-art CNC machining. We specialize in 6063, 6061, and 5083 alloys, ensuring every solar panel frame meets the rigorous demands of outdoor environmental exposure. Our anodizing and powder coating processes provide the 25-year corrosion resistance required for modern PV modules.
The global shift toward "Net Zero" emissions has catalyzed an unprecedented demand for Aluminium Solar Panel Frames. As the skeletal system of a solar module, the frame provides structural integrity, protects the glass edges, and facilitates secure mounting. Today, the industry is moving towards larger module sizes and bifacial technology, which requires frames with higher tensile strength and thinner profiles to maximize efficiency without compromising durability.
In the commercial landscape, procurement officers from Europe, North America, and Southeast Asia are increasingly looking for integrated supply chain partners. China’s advantage lies not just in cost, but in the rapid prototyping and massive scalability that local factories like Dongguan Cellar Aluminum provide. Our proximity to high-grade bauxite resources and advanced smelting technology ensures material consistency that is critical for large-scale utility solar farms.
Utilizing AI-driven simulation to optimize the cross-sectional design of aluminum profiles, reducing weight by up to 15% while maintaining wind load resistance of 2400Pa-5400Pa.
Adopting advanced fluorocarbon and sandblasted anodizing techniques to withstand extreme desert heat, coastal salt spray, and arctic cold conditions.
Focusing on low-carbon aluminum production (Green Aluminum) to help global clients reduce their Scope 3 emissions in the solar value chain.
1. Scale and Speed: Chinese factories operate at a scale that allows for the simultaneous fulfillment of multiple gigawatt-scale projects. Our lead times are typically 30-40% faster than regional manufacturers in other parts of the world.
2. Technical Expertise: With over a decade of specialization, our engineering teams understand the nuances of Aluminium solar panel frames, from the importance of precise corner-key fitment to the uniformity of the anodized layer.
3. Comprehensive Testing: We conduct rigorous salt spray tests, cross-cut adhesion tests, and mechanical load tests to ensure compliance with international standards like ASTM B209 and GB/T 3880.
4. Cost-Efficiency: The integrated industrial cluster in Dongguan allows us to minimize logistics costs for raw materials, passing those savings directly to our global exporters and partners.
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. The company focuses on providing high-quality aluminum products widely used in construction, transportation, machinery manufacturing, packaging, electronics, and industrial engineering sectors.
Established in 2011 in Dongguan, China, Cellar Aluminum began as a small aluminum processing workshop focused on basic sheet cutting and surface finishing services. With the rapid growth of industrial demand for lightweight and corrosion-resistant materials, the company expanded into large-scale production of aluminum plates, sheets, and tread plate solutions. By 2016, it had developed advanced capabilities in rolling, cutting, anodizing, and precision surface treatment.
Today, Dongguan Cellar Aluminum Co., Ltd. operates modern production facilities equipped with automated rolling lines, precision cutting systems, and advanced surface treatment technologies. The company emphasizes strict quality control, stable material performance, and customized specifications to meet diverse industrial requirements.
With a strong export network across Southeast Asia, the Middle East, Europe, and South America, Cellar Aluminum continues to deliver reliable and cost-effective aluminum solutions. Committed to innovation, sustainability, and material performance enhancement, the company plays an active role in supporting global industrial manufacturing and modern infrastructure development.
Our frames are engineered to resist the abrasive nature of sand and extreme diurnal temperature shifts found in the Middle East and Saharan projects.
Using 5083 and 6063 marine-grade aluminum alloys, we provide frames that resist salt-air corrosion, vital for the burgeoning floating solar market.
For the European market, we offer "Full Black" anodized frames that provide a sleek, architectural finish for home solar integration.
