For over three decades, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has stood at the forefront of engineered tank systems and innovative roofing technologies.Today, one of our most advanced and in-demand innovations is the Aluminum Dome Roof—an architectural marvel designed to protect the quality of stored liquids in a lightweight, corrosion-resistant, and maintenance-free structure. In regions with high humidity and dynamic weather conditions, like Thailand, our Aluminum Dome Roofs for potable water tanks have become a preferred solution for municipalities, utility companies, and industrial clients.
As a trusted Aluminum Dome Roofs manufacturer, Center Enamel combines engineering excellence, cutting-edge materials, and project customization to offer reliable protection for potable water tanks—ensuring clean water storage under optimal conditions.
Aluminum Dome Roofs are self-supporting, column-free, and geometrically precise structures designed to cover circular tanks. Constructed from high-strength aluminum alloy components, these roofs feature a geodesic pattern that distributes loads efficiently across the surface without requiring internal supports.
Their unique engineering advantages include:
Corrosion resistance: Naturally resistant to rust, salt, and humidity
Non-reactivity: Ideal for storing drinking water, with no risk of contamination
Modular design: Prefabricated for quick on-site assembly and integration
Our aluminum domes are tailored to fit tanks of any diameter, from small rooftop units to massive municipal reservoirs. They are compatible with Glass-Fused-to-Steel, welded steel, concrete, and bolted epoxy-coated tanks.
Thailand’s diverse geography—from bustling urban centers to remote rural areas—poses a variety of challenges for water storage infrastructure. With year-round high humidity, intense sun exposure, and frequent rainfall, protecting the integrity of potable water is a national priority.
Unlike steel roofs that require regular painting and anti-corrosion treatment, aluminum dome roofs are naturally resistant to corrosion. Their aluminum alloy composition forms a passive oxide film that defends against oxidation, acid rain, and tropical humidity—ensuring clean water storage with minimal maintenance.
Open-top tanks are vulnerable to external contamination from dust, insects, animals, and airborne pollutants. Our dome roofs offer sealed protection, preventing algae formation by blocking sunlight and reducing the need for additional chemical treatments.
This is crucial in maintaining the potability of water, especially in Thailand’s climate where heat and sunlight accelerate microbial growth.
By reducing thermal gain, aluminum dome roofs help maintain cooler water temperatures, which improves water quality and lowers the energy burden on treatment systems. Their lightweight structure also minimizes load stress on tank walls and foundations, resulting in lower construction and lifecycle costs.
Thailand’s water infrastructure is evolving to meet increasing demands from urban expansion, industrial growth, and rural development. Aluminum dome roofs from Center Enamel are playing a vital role across multiple water storage scenarios:
Cities like Bangkok, Chiang Mai, and Pattaya rely on above-ground tanks to store treated water before distribution. Dome roofs ensure the stored water remains clean, cool, and free from contaminants, helping municipal agencies meet water safety regulations.
In remote provinces where centralized treatment may not be available, community-managed potable water tanks need reliable protection. Aluminum dome roofs offer a low-maintenance, long-life solution that preserves water quality under harsh environmental conditions.
Thailand’s manufacturing hubs—including automotive, food processing, and pharmaceuticals—require on-site potable water tanks. Aluminum dome roofs ensure compliance with hygiene standards while reducing operational overhead.
When it comes to potable water tank protection, Center Enamel delivers more than just a product—we deliver a partnership in performance, reliability, and compliance. Here’s why clients around the world trust us:
