In the face of growing environmental challenges and increasing global demand for clean water, the safe storage of drinking water has never been more important. At Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), we are proud to be at the forefront of storage tank innovation. With over 30 years of industry experience, we specialize in high-quality, durable storage solutions, including our widely acclaimed Glass-Fused-to-Steel tanks and cutting-edge aluminum dome roofs.
Our aluminum dome roofs are designed specifically for extreme environments, making them the perfect cover solution for drinking water storage tanks. These structures offer superior weather resistance, extended durability, low maintenance, and strong environmental compatibility. As a trusted supplier to over 100 countries worldwide, Center Enamel continues to support
water infrastructure projects with advanced engineering and reliable materials.
Aluminum dome roofs are geodesic, self-supporting structures composed of high-strength aluminum alloy components. Their unique design allows for clear-span coverage, meaning the roof can span large diameters without the need for internal support columns. This feature ensures maximum usable volume within the tank and prevents any obstruction that could interfere with the quality or distribution of stored water.
Constructed from prefabricated modules—such as struts, hubs, and panels—our aluminum domes are assembled on-site, allowing for efficient transportation and quick installation. Once in place, the dome creates a fully sealed cover that protects drinking water from environmental contaminants such as dust, rain, snow, debris, and ultraviolet (UV) radiation.
Drinking water storage tanks are typically located in open or partially sheltered environments, where they are directly exposed to the elements. Over time, weather conditions such as heavy rainfall, strong winds, UV exposure, and fluctuating temperatures can compromise both the structure of the tank and the quality of the water it holds.
Aluminum dome roofs play a vital role in countering these challenges. Their corrosion-resistant nature ensures long-term durability without the need for chemical coatings or regular repainting. This not only protects the structural integrity of the tank but also ensures that the water remains clean, safe, and potable over long periods.
In areas prone to extreme weather—such as coastal zones, deserts, or regions with heavy snowfall—the aerodynamic shape of the aluminum dome helps reduce wind uplift, prevents snow accumulation, and minimizes storm damage. The reflective surface of aluminum also helps regulate internal temperatures by deflecting solar heat, reducing the risk of microbial growth and algae formation in warm climates.
Aluminum naturally forms a protective oxide layer, making it highly resistant to corrosion. This makes it especially suitable for humid and saline environments where traditional materials might degrade over time.
Despite their large coverage capabilities, aluminum domes are lightweight, reducing the load on the tank’s walls and foundation. This translates to lower construction and maintenance costs while improving safety during seismic events.
Once installed, aluminum dome roofs require virtually no maintenance. Unlike steel roofs, they do not require periodic coating or rust prevention treatments, offering long-term savings and convenience for municipal and industrial clients.
Every dome is custom-engineered to match the dimensions and environmental requirements of the site. The modular nature allows for easy upgrades or retrofits in the future and can accommodate tanks of various diameters and heights.
Aluminum is recyclable, making it a sustainable choice for green infrastructure projects. By choosing aluminum dome roofs, clients are investing in a product that contributes to reduced environmental impact across its lifecycle.
Center Enamel has provided aluminum dome roofs for a wide variety of drinking water projects around the world. Below are a few examples highlighting the versatility and effectiveness of our solutions:
In Costa Rica, we supplied Glass-Fused-to-Steel tanks covered with aluminum dome roofs to enhance the country’s potable water infrastructure. The aluminum roofs were selected for their resistance to the region’s tropical humidity and rainfall, protecting water purity and ensuring compliance with sanitation standards.
In Panama, where strong winds and tropical storms are frequent, aluminum dome roofs proved invaluable in protecting above-ground drinking water tanks. Our engineering team customized the domes for wind uplift resistance and rapid onsite assembly, reducing installation time and operational disruption.
In Malaysia, the hot and humid climate poses challenges for water storage. Our aluminum domes helped minimize heat absorption and prevented microbial growth inside the tanks, delivering a safe and hygienic water supply to remote communities and industrial facilities.
At Center Enamel, our commitment to quality and innovation sets us apart as a global leader in storage tank technology. Our aluminum dome roofs are backed by industry certifications and are designed to meet or exceed international standards such as AWWA D108 and API 650.
Having completed projects in more than 100 countries, Center Enamel understands local compliance requirements, logistics challenges, and regional climates. This experience ensures successful project delivery, no matter the location.
From design to manufacturing, transportation, and on-site installation, we offer complete end-to-end service. Our customer-first approach means that each project is executed with precision, professionalism, and ongoing technical support.
