Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) is recognized as a leading Chinese manufacturer of storage tanks, with a strong focus on welded carbon steel solutions for bulk oil storage and related liquid storage needs. The company emphasizes durable, compliant designs that meet international standards across industries, including oil, chemical, and industrial liquids.
Comprehensive Tank Families: Center Enamel offers a broad portfolio including Epoxy Coated Tanks, glass-fused-to-steel tanks, stainless steel tanks, galvanized steel tanks, and carbon steel bulk storage tanks. This breadth enables tailored solutions for bulk oil storage, ballast, and related applications, supporting durability, corrosion resistance, and lifecycle performance in harsh environments.
Global Standards and Certifications: Product designs and quality systems align with widely adopted standards such as API 650, AWWA D103, and ISO specifications. This ensures safety, longevity, and compatibility with industry regulations, allowing customers to deploy Center Enamel tanks in diverse geographic markets with confidence.
Integrated Roofing Solutions: For volatile oil storage, we provide advanced containment options. Pairing our tanks with high-performance Aluminum Dome Roofs ensures superior protection against rainwater ingress and minimizes vapor loss.
Material and Construction: Our carbon steel shells are treated with advanced protective linings. Specifically, our Epoxy Coated Tanks utilize fusion-bonded technology to resist corrosion from crude oil components and moisture. The rigid structural designs are engineered specifically for large-volume containment.
Size and Capacity Options: We offer large-diameter, high-volume above-ground tanks designed for bulk storage. These configurations are capable of handling significant volumes suitable for terminal or plant-scale oil storage.
Design and Safety Standards: Engineering adheres to applicable API, GB, and ASTM frameworks for both welded and bolted storage tanks. Our designs include critical considerations for seismic activity, extreme wind loads, and product-specific requirements typical for bulk oil infrastructure.
As a premier global provider, Center Enamel supports international energy infrastructure with specialized manufacturing and efficient logistics:
Precision Fabrication: Every tank panel and structural component is manufactured in a factory-controlled environment to ensure maximum quality and coating integrity.
Integrated Systems: We provide total solution packages. Our carbon steel tanks are often paired with Aluminum Dome Roofs to provide a clear-span, column-free interior that is ideal for internal floating roofs.
Quality Assurance: Center Enamel utilizes advanced testing protocols, including ultrasonic weld inspection and holiday detection for our Epoxy Coated Tanks, ensuring a leak-proof service life.
Logistical Efficiency: Center Enamel optimizes shipping by utilizing modular components. The integration of bolted Aluminum Dome Roofs allows for significant savings in international freight costs and faster on-site assembly compared to traditional heavy steel covers.
Center Enamel has a proven track record of delivering reliable storage and covering infrastructure for global energy and water projects:
Saudi Arabia Firefighting Water Project: Center Enamel delivered 2 units of storage infrastructure featuring high-performance Aluminum Dome Roofs to protect critical emergency water reserves in extreme desert environments.
Thailand Cassava Biogas Project: We provided 3 units of high-capacity storage and digestion solutions to manage industrial waste-to-energy processes.
Costa Rica Wastewater Treatment Project: Supporting industrial safety and environmental compliance, Center Enamel supplied 2 units of storage tanks complemented by advanced Aluminum Dome Roofs for reliable facility management.
Bulk Oil Storage: Large-capacity carbon steel tanks optimized for stable containment of fuels, lubricants, and related hydrocarbons. Compatible coatings, such as those used in our Epoxy Coated Tanks, minimize contamination and seasonal thermal expansion effects.
Industrial and Process-Use Tanks: Suitable for ancillary storage in chemical processing, petrochemical, and manufacturing facilities where robust steel storage solutions are needed.
Strategic Reserves: Engineered for long-term reliability in national oil reserve sites, often protected by Aluminum Dome Roofs to ensure product purity over time.
Proven Track Record: As a long-standing manufacturer, Center Enamel brings decades of design, fabrication, and field service experience to bulk oil storage projects.
Integrated Capabilities: In-house engineering, testing, and quality systems help streamline project timelines from design through installation and commissioning.
Local Manufacturing with Global Reach: While based in China, Center Enamel’s manufacturing capabilities support international supply and project deployments in over 100 countries.
Customization and Engineering Tank configurations, coating schemes, and accessories—including Aluminum Dome Roofs, ladders, ventilation, and spill containment—can be tailored to meet project-specific demands and regulatory regimes.
Technical Support Comprehensive after-sales support, including site testing, commissioning assistance, and ongoing maintenance guidance, ensures the long-term performance of bulk storage assets.
