China Leading Dry Bulk Storage Tanks Manufacturer

China Leading Dry Bulk Storage Tanks Manufacturer

Center Enamel — the dry bulk storage tanks brand name of Shijiazhuang Zhengzhong Technology Co., Ltd. — has grown from a pioneering Chinese tank producer into a global leader in engineered storage systems for minerals, grains, powders, fertilizers and industrial solids. As industries worldwide demand safer, cleaner and more efficient ways to handle bulk materials, Center Enamel stands out as China’s leading dry bulk storage tanks manufacturer, combining advanced bolted-steel designs, proven coating technologies and international engineering standards.

The Growing Importance of Dry Bulk Storage

Across mining, cement, agriculture, food, plastics and chemicals, dry bulk materials sit at the heart of global supply chains. They must be stored, blended and transferred reliably to keep production lines running and logistics on schedule. Poorly designed silos and bulk tanks can lead to flow blockages, caking, contamination, dust emissions, structural failures and major safety incidents. Modern operators therefore look for storage systems that deliver:

• Stable, predictable flow for powders, granules and pellets
• High structural safety under asymmetric loads, wind and seismic forces
• Clean, corrosion‑resistant interiors that protect product quality
• Fast on‑site installation with minimal disruption and downtime

Center Enamel’s dry bulk storage tanks and silos are engineered precisely for these challenges, serving demanding projects in mining, minerals, feed and grain, fertilizer, food ingredients and industrial powders around the world.

About Center Enamel — A Global Storage Tank Leader

Founded in 2008, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is recognized as one of Asia’s most experienced manufacturers of bolted steel storage tanks, offering Glass‑Fused‑to‑Steel, fusion‑bonded epoxy, stainless steel and galvanized steel configurations. Over more than three decades the company has delivered storage solutions for liquids, slurries and dry bulk materials in more than 80–100 countries, supplying industries from water and wastewater to agriculture, biogas, energy and bulk solids.

Key strengths include:

• A large‑scale manufacturing base with annual capacity of about 300,000 steel plates, supporting rapid production and global delivery.
• Strict adherence to international standards such as AWWA D103‑09, ISO 28765, NSF/ANSI 61, EN 1090, OSHA, NFPA and CE, ensuring structural integrity and safety compliance.
• A diversified product portfolio covering dry bulk tanks and silos, agricultural water tanks, drinking water tanks, process water tanks, wastewater tanks and biogas digesters, enabling integrated storage solutions across entire sites.

With thousands of successful tank and silo installations, Center Enamel has earned a reputation for robust engineering, long‑term reliability and responsive service in global markets.

Engineered Dry Bulk Tanks and Silos

Center Enamel’s dry bulk storage tanks & silos are purpose‑designed to store a wide range of materials safely and efficiently, including cement, fly ash, lime, sand, ores, grains, animal feed, sugar, starch, plastic pellets, chemical powders and fertilizers. Bolted construction allows modular sizing and rapid on‑site erection, while different internal coatings and steel grades are selected to match product abrasiveness, moisture content and chemical characteristics.

Typical dry bulk solutions include:

• Vertical silos for gravity discharge to truck loading stations or process lines
• Large‑diameter flat‑bottom tanks with mechanical reclaim systems
• Hopper‑bottom tanks optimized for mass flow or funnel flow depending on material properties
• Connected silo batteries with transfer conveyors and dust control systems

By combining structural design with bulk handling know‑how, Center Enamel helps operators reduce bridging, ratholing, segregation and dust, all of which can compromise productivity and safety.

Advanced Materials and Coatings

A major differentiator for Center Enamel is its heritage in Glass‑Fused‑to‑Steel and fusion‑bonded epoxy technologies, which it applies not only for liquids but also for many dry bulk environments where corrosion resistance, cleanability and long service life are critical.

Key characteristics include:

• Glass‑Fused‑to‑Steel (GFS / GLS): Molten glass is fused to steel plate at around 820–930 °C, forming a hard, chemically inert coating that resists corrosion, abrasion and weathering while maintaining strong adhesion to the steel substrate.
• Fusion‑bonded epoxy coatings: Electrostatic application and high‑temperature curing create a dense protective layer ideal for many industrial solids where moisture and mild chemical attack are present.

These advanced coatings enhance performance in applications such as fertilizers, mineral powders and hygroscopic materials, where uncoated carbon steel silos may corrode or contaminate product over time.

Structural Design and Standards Compliance

Dry bulk storage imposes unique engineering challenges: non‑uniform loads during filling and discharge, internal friction, pressure peaks, and dynamic effects from flow or vibration. Center Enamel’s engineering team designs tanks and silos in line with recognized international codes and uses modern analysis tools to verify safety margins.

Design highlights:

• Finite element analysis (FEA) to evaluate shell stresses, roof loads, stiffener performance and anchorage under worst‑case conditions.
• Consideration of seismic and wind loads, particularly for tall, slender silos and exposed industrial sites.
• Optimization of hopper angles and outlet geometries to support reliable material flow and minimize stagnant zones, tailored to bulk density and flow properties.

Compliance with standards such as AWWA, ISO, OSHA and NFPA complements project‑specific requirements in mining, food, chemical and energy sectors.

Broad Industry Applications

Center Enamel positions its dry bulk storage tanks and silos as multi‑industry solutions, engineered for both greenfield installations and brownfield upgrades.

Major application sectors include:

• Mining and Minerals: Storage of ores, concentrates, tailings filter cake, cement and lime used in processing.
• Power and Cement: Fly ash, slag, cement clinker, gypsum and fuel additives.
• Agriculture and Feed: Grain, corn, wheat, soy, silage, animal feed and premixes.
• Food and Beverage: Sugar, flour, starches, malt, salt and food‑grade additives.
• Chemicals and Plastics: Resins, pellets, powders, catalysts and specialty chemicals.

A dedicated dry bulk portfolio helps customers standardize on a single supplier across multiple materials, sites and countries, simplifying maintenance, spare parts and training.

Advantages of Center Enamel Dry Bulk Tanks

Several core advantages explain why Center Enamel is frequently chosen as China’s leading supplier of dry bulk storage tanks for mining, minerals and other industries.

• Modular Bolted Construction
  • Prefabricated panels, roofs and accessories are shipped in compact packages and assembled on‑site, enabling installation in locations that are hard to access for large welded structures.
  • This approach often shortens project schedules and reduces crane time and civil works compared to conventional concrete or welded steel silos.
• Long Service Life and Low Maintenance
  • Advanced coatings and corrosion‑resistant materials reduce the need for internal repainting or frequent repairs, especially for dusty, moisture‑prone or corrosive environments.
  • Smooth interior surfaces support easier cleaning and material change‑overs, particularly important in multi‑product plants.
• Flexible Capacity and Layout
  • Bolted tanks can be tailored in diameter, height and hopper configuration to deliver optimized storage volumes and footprint use.
  • Multiple silos can be linked with conveying and loading systems into integrated bulk handling terminals.
• Global Experience and Support
  • With projects in more than 80–100 countries, Center Enamel understands local regulations, climatic conditions and logistical constraints, allowing it to adapt designs and execution strategies for each region.
