Highly corrosion-resistant Epoxy coated steel tanks as wastewater tank
Wastewater storage tanks play a crucial role in modern urban and industrial facilities. With the continuous development of urbanization and industrialization, the handling and storage of wastewater have become increasingly urgent. Wastewater tanks are not only a key component of wastewater treatment systems but also play a critical role in addressing natural disasters, emergency situations, and long-term planning. They provide the foundation for sustainable water resource management and environmental protection.
In the selection of materials for wastewater tanks, epoxy-coated steel tanks have garnered significant attention due to their unique performance and versatile applications. Epoxy resin is a high-performance polymer material with excellent corrosion resistance and chemical resistance. Its applications extend beyond traditional fields, demonstrating significant potential in wastewater storage.
With over 30 years of experience in tank research, production, and construction, Center Enamel, in collaboration with the world-leading paint and coating manufacturer AkzoNobel, has jointly developed the technology of fused epoxy coating. Epoxy coating is an advanced anti-corrosion coating known for its excellent corrosion resistance and adhesion. Additionally, the epoxy coating technology employs a special construction process - electrostatic spraying, which enhances the uniformity and adhesion of the coating, effectively extending the lifespan of the tank.
Tanks coated with epoxy resin using this technology are not only technologically advanced and cost-effective but also easy and quick to install. The quality meets requirements such as AWWA D103-09 and ISO 9227/ASTM B117. Upon its introduction, it has gained recognition from customers.

Epoxy coated steel tank Coating
Compared to other available epoxy resins on the market, our epoxy resin is one of the most durable epoxy coatings. Each sheet undergoes high-pressure testing to ensure defect-free performance under testing voltages. The optimal control over the external coating overspray ensures that the internal coating complies with drinking water regulations. The coating undergoes and must pass various types of tests to ensure high performance and compliance with international quality standards. The inner surface is coated with a factory electrostatic powder coating, providing high quality and consistent uniform smoothness.
The external coating is a combination of epoxy resin primer and ultra-durable polyester topcoat. The external coating undergoes and must pass various types of tests to ensure high performance and compliance with international quality standards. The formula complies with proper substance control, allowing the coating to achieve the highest global safety and environmental performance certifications.
