Aluminum Coil For Water Tank Dome Manufacturing

Haomei Aluminum is specialized in aluminum coils for water tank domes, core advantages lie in alloy compatibility, product durability, and scenario adaptability, which are key to our success in the international market.

Regarding alloy specifications, combine the pressure requirements of water tank domes, the usage environment, and the standards of export regions, promoting two core alloy series. Both strictly comply with the national standard GB/T 3880.1-2023, while also conforming to international standards such as EN 1090 and AAMA 2605-20, ensuring smooth export customs clearance.

Among our products, the 3003 aluminum coil is our largest export volume standard. It is an aluminum-manganese alloy with a manganese content controlled at 1.0-1.5% and an aluminum content exceeding 99.8%. Thickness can be customized from 0.5-1.0mm, and width from 100-2500mm. It is perfectly suited for stamping and bending processes of domes for small and medium-sized domestic and industrial water storage tanks, offering excellent cost-effectiveness. It is the preferred choice for emerging markets in Southeast Asia and the Middle East, and we have served over 50 overseas water tank manufacturing projects.

For high-end needs and special environments, we offer the 5052 aluminum-magnesium alloy coil. With a magnesium content of 2.2-2.8% and trace amounts of chromium added to improve corrosion resistance, its tensile strength reaches 230-280 RM/MPa, significantly higher than the 3003 series. It is suitable for large high-pressure water tanks, marine environmental water tanks, and high-end European projects. This product has passed multiple international certifications such as CE and BIS, allowing direct entry into markets such as the EU and India. It solves a core pain point for customers’ export certification needs and is one of our core competitive advantages.

In terms of advantages and characteristics, based on actual feedback from export scenarios, our aluminum coils have three outstanding advantages.

First, they exhibit exceptional corrosion resistance. The 3003 series, enhanced by manganese, resists corrosion from humid and ordinary water, while the 5052 series is adaptable to complex environments such as seawater and industrial wastewater. In the salt spray regions of the Middle East and the high-temperature, high-humidity environments of Southeast Asia, their service life is 3-5 years longer than competing products, significantly reducing customer maintenance costs.

Second, they offer superior processing performance. The aluminum coils have a smooth surface and uniform thickness. After special annealing treatment, they can easily achieve the curved bending and stamping required for domes, minimizing cracking and deformation, reducing processing losses for customers. This is a key reason why we were chosen by European customers from among many suppliers.

Third, they combine lightweight design with environmental friendliness. With a density of only 2.7g/cm³, aluminum coils are more than 30% lighter than steel, reducing the overall weight of the water tank, lowering transportation and installation costs. They also align with global environmental trends, being 100% recyclable and meeting the environmental requirements of the European and American markets.

In terms of application advantages, our aluminum coils are fully adaptable to various water tank dome scenarios, whether it’s domestic water storage tanks, industrial production water tanks, fire-fighting water tanks, or marine water storage equipment, precisely matching your needs. Leveraging years of export experience, we can customize alloy specifications and surface treatment processes based on the climate and water quality differences in our clients’ regions. For example, we optimize UV-resistant coatings for clients in tropical areas and add anti-corrosion treatments for clients in highly corrosive regions. Furthermore, we own our own aluminum plant, enabling us to control raw materials independently. This provides significant advantages in mass production, allowing us to offer more competitive prices and delivery cycles controlled within 15-20 days, far exceeding the industry average. Coupled with a professional export customs clearance team, we can solve a series of problems for clients, such as certification and customs declaration, ensuring smooth product delivery.

For many years, Haomei’s aluminum coil for water tank domes have won global customer recognition thanks to precise alloy compatibility, reliable product quality, and comprehensive export services. We not only provide products but also offer one-stop solutions tailored to your export needs, which is the core of our competitiveness in the international market. We look forward to working with you to provide your water tank manufacturing business with high-performance, cost-effective, and highly adaptable aluminum coil products.
