Our infrastructure includes eight High-Frequency welded lines, capable of a staggering 100,000-ton monthly output. We are not just a manufacturer; we are a strategic partner providing integrated solutions for the construction, automotive, and home appliance sectors.
20 expert engineers with 10+ years of experience drive our innovation.
Exporting to 100+ countries across the Americas, SE Asia, and Africa.
The global demand for 20g Aluzinc coils (approx. 0.9mm to 1.0mm thickness) has seen an unprecedented surge. Aluzinc, an alloy consisting of 55% Aluminum, 43.4% Zinc, and 1.6% Silicon, represents the pinnacle of anti-corrosion technology in the steel industry. Unlike traditional galvanized steel, Aluzinc offers 2 to 6 times the atmospheric corrosion resistance, making it the preferred choice for environments exposed to extreme weather and industrial pollutants.
In the modern era of "Sustainable Infrastructure," procurement managers are shifting away from short-term cost savings toward long-life cycle materials. 20g Aluzinc is now the benchmark for high-end roofing and cladding.
The solar energy boom has created a massive niche for Aluzinc steel. Its high thermal reflectivity and structural integrity make it ideal for solar mounting structures and PV farm foundations.
As carbon taxes become a global reality, Aluzinc’s 100% recyclability and long lifespan contribute significantly to LEED and BREEAM certifications for international construction projects.
For international buyers, sourcing Wholesale 20g Aluzinc coils involves complex logistical and quality hurdles. Our factory simplifies this through a vertically integrated supply model. Whether you are a distributor in South America or a contractor in the Middle East, our 20+ inspectors ensure every coil meets GB, ASTM, BS, or DIN standards.
Why Procurement Teams Choose Us:
Used extensively for high-durability roofing, sandwich panels, and rainwater drainage systems in coastal regions.
The 20g thickness is perfect for the structural chassis of refrigerators, washing machines, and HVAC units due to its fingerprint resistance.
Providing long-term protection for greenhouses and barns against ammonia and corrosive organic matter.
Utilized in heat shields, mufflers, and underbody components where heat and corrosion resistance are critical.
From cable trays to electrical cabinets, the easy formability of 20g Aluzinc makes it a versatile manufacturing base.
Our competitive edge lies in the synergy between Technical Expertise and Operational Excellence. With over 15 years in the field, we understand that price is nothing without consistency.
Utilizing state-of-the-art testing equipment from Germany and Japan, we verify the coating weight, T-bend performance, and salt spray resistance of every batch of 20g Aluzinc coils. All our raw materials are backed by CE and GB certifications.
