The Future of Infrastructure: Bolted Steel Tanks as the Premier Form of Field Erection
For centuries, large-scale liquid and bulk storage has been a foundational pillar of industrial and municipal infrastructure. From water treatment and fire protection to industrial processing and agricultural storage, the demand for robust, high-capacity vessels is a constant. Traditionally, these structures have been built on-site using conventional methods like concrete construction or field-welded steel. These approaches, while time-tested, are often fraught with challenges—lengthy project timelines, high costs, and a susceptibility to environmental and human variables that can compromise quality. The very act of "field erecting" a tank has historically been synonymous with complexity and risk.
At Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), we have redefined what it means to erect a tank in the field. We are not simply a tank manufacturer; we are a leading innovator in engineered containment solutions. Our Bolted Steel Tanks represent a paradigm shift in field-erected infrastructure, offering a modern, efficient, and technologically superior alternative to conventional methods. By combining the strength and flexibility of steel with factory-applied, corrosion-resistant coatings, we have created a modular, field-erected solution that delivers unparalleled quality, speed, and long-term value. Leveraging our signature Glass-Fused-to-Steel (GFS) and robust Fusion Bonded Epoxy (FBE) technologies, we are building the future of industrial storage, one bolted panel at a time.
The Challenge of Traditional Field-Erected Tanks
Before understanding the benefits of a bolted steel solution, it is essential to recognize the inherent limitations of traditional field erection methods. These challenges are the very reason a new approach was needed.
Welded Steel Tanks
Welded steel tanks, while common, pose numerous hurdles. Their construction is a slow, labor-intensive process that requires highly skilled welding crews on-site for extended periods. This process is often at the mercy of the elements; rain, wind, or extreme temperatures can delay or even halt construction, leading to costly project overruns. More critically, the quality of a weld is highly dependent on the skill of the welder and the conditions of the day. A single inconsistent weld can create a weak point in the tank's structure, making it susceptible to corrosion and eventual failure. This reliance on on-site fabrication means that the most critical part of the tank's integrity—the seams—are subject to the least controlled manufacturing environment.
Concrete Tanks
For large-scale water and wastewater storage, concrete basins have long been the default choice. However, their construction is an even longer process, involving extensive formwork, pouring, and a lengthy curing time that can take weeks or even months. The cost of materials and specialized labor is significant. Furthermore, concrete is susceptible to cracking over time due to ground movement, thermal expansion, or chemical attack from the stored liquid. Once a crack forms, it can lead to leaks, contamination, and a compromised structure that is difficult and expensive to repair. Unlike bolted steel tanks, concrete structures are permanent; they offer no flexibility for future expansion or relocation if a facility's needs change.
The Bolted Steel Paradigm Shift: A Revolution in Field Erection
Center Enamel's bolted steel tanks provide a revolutionary answer to these challenges, fundamentally transforming the process of field erection from a complex, on-site fabrication to a streamlined, on-site assembly. This paradigm shift is rooted in the principle of modularity and factory-controlled quality.
Modular, Factory-Fabricated Components: The heart of our technology lies in our state-of-the-art manufacturing base, spanning over 150,000m². Here, every steel panel is precisely cut, drilled, and coated in a highly controlled environment. This process ensures perfect dimensions and a flawless finish, with all the critical work completed long before a single panel arrives on-site. The consistency achieved in our factory is simply impossible in the unpredictable field environment.
Rapid & Safe On-Site Assembly: Once on-site, the pre-fabricated panels are simply lifted into place and bolted together. This process is significantly faster than welding or pouring concrete. It drastically reduces the need for specialized on-site labor and eliminates the risks associated with hot work. With a much smaller footprint and a safer process, our bolted tanks minimize disruption to ongoing operations, making them ideal for both new construction and upgrades. The speed of installation—a matter of weeks rather than months—translates directly to a faster return on investment.
Unmatched Quality Control: This is perhaps the single most important advantage of a bolted steel tank. The corrosion-resistant coatings, whether GFS or FBE, are applied in our factory using automated processes that ensure a uniform thickness and perfect adhesion. Unlike field-applied coatings, which can be affected by dust, humidity, or inconsistent application, our coatings are flawless. We are the first manufacturer in China to independently develop double-sided enameling technology for hot-rolled steel plates, a breakthrough that showcases our commitment to quality. This dedication is validated by our numerous certifications to international standards such as ISO 28765, NSF61, WRAS, and FM.
Center Enamel's Flagship Technologies for Field Erected Tanks
As a leader in engineered containment, Center Enamel offers a range of cutting-edge technologies that are ideally suited for field-erected tanks. Each material is selected for its superior performance in specific applications, ensuring our clients receive the most effective and durable solution.
Glass-Fused-to-Steel (GFS) Tanks
Our GFS tanks, also known as Glass-Lined Steel (GLS) tanks, represent the pinnacle of containment technology. The GFS process involves firing at a high temperature of 820°C-930°C, causing molten glass to react with the surface of the steel plate. This fusion creates a robust, chemically inert, and impermeable bond that combines the strength of steel with the unparalleled corrosion resistance of glass.
Ultimate Corrosion and Wear Resistance: The glass lining is completely impervious to a wide range of corrosive agents, from highly acidic industrial chemicals to the biological byproducts found in municipal sewage. With a hardness of 6.0 (Mohs), it provides exceptional wear resistance, making it ideal for liquids with abrasive solids.
Non-Contaminating and Hygienic: The ultra-smooth, non-porous surface of a GFS tank will not leach any compounds into the stored liquid, making it the preferred choice for drinking water and food-grade process water. Our products are certified to meet rigorous standards like NSF61 and WRAS, providing a guarantee of purity.
Long-Term Value: With a design life exceeding 30 years, our GFS tanks require minimal maintenance, eliminating the need for periodic relining or recoating. This leads to a significantly lower total cost of ownership compared to traditional solutions. We have proven our capabilities by fabricating the largest GFS tank in Asia, with a single volume of 32,000m³, and the highest, reaching 34.8m.
Fusion Bonded Epoxy (FBE) Tanks
For many industrial and municipal applications, our FBE tanks provide a highly effective and cost-effective solution. This technology involves electrostatically applying a thermoset polymer powder to the steel panels, which is then cured in an oven to create a thick, uniform, and durable barrier.
Robust Corrosion Protection: The FBE coating provides a tough, uniform barrier against the corrosive effects of many industrial water and wastewater chemistries. The factory application ensures a level of quality and consistency far superior to on-site linings.
Exceptional Value: FBE tanks offer a perfect balance of performance and affordability, making them an excellent choice for projects with budget considerations that still require a high level of durability and protection. Our FBE tanks are a reliable and trusted solution, with a proven track record of withstanding harsh industrial environments.
