Meeting the Global Demand for Dry Bulk Solids Storage

Dry bulk solids are essential to modern industry and agriculture, yet they pose complex storage challenges. Materials such as cement, grain, fertilizer, lime, fly ash, coal ash, biomass pellets, and industrial powders require storage systems that can withstand:

Abrasion from solid particles

Internal pressure from bulk loading

Moisture exposure and condensation

Chemical reactivity and dust generation

Long-term cyclic loading during filling and discharge

Traditional storage options, including concrete silos and welded steel tanks, often suffer from cracking, corrosion, leakage, high maintenance costs, and limited adaptability. Recognizing these challenges, Center Enamel has dedicated itself to developing advanced dry bulk solids tank solutions that combine structural strength, superior surface protection, and flexible modular design.

Center Enamel: A Pioneer in Bolted Tank Technology

Founded in 2008, Shijiazhuang Zhengzhong Technology Co., Ltd. is the first manufacturer in China to independently develop and produce Glass-Fused-to-Steel tanks and has grown into the most experienced bolted tank manufacturer in Asia. From the outset, Center Enamel invested heavily in material science, enameling technology, and structural engineering to support a wide range of storage applications—including dry bulk solids.

Today, Center Enamel operates an advanced manufacturing base covering more than 150,000 square meters, supported by:

Nearly 200 patented enameling technologies

Dedicated R&D and testing laboratories

Automated production and inspection systems

A comprehensive quality management framework

This strong foundation enables Center Enamel to deliver consistent, high-quality dry bulk solids tanks for projects of all sizes and complexities.

Glass-Fused-to-Steel Technology: A Breakthrough for Dry Bulk Storage

At the core of Center Enamel’s dry bulk solids tanks is its proprietary Glass-Fused-to-Steel (GFS) technology. This process involves fusing molten glass to specially prepared steel plates at temperatures between 820°C and 930°C, creating a permanent chemical bond between the two materials.

The result is a surface that combines:

The mechanical strength and flexibility of steel

The chemical inertness and abrasion resistance of glass

For dry bulk solids storage, this combination offers critical advantages:

Excellent resistance to abrasion caused by solid particles

Protection against moisture-induced corrosion

A smooth, non-stick surface that promotes material flow

Resistance to chemical attack from aggressive powders

Compared to epoxy-coated or painted steel tanks, GFS tanks offer significantly longer service life and far lower maintenance requirements, making them ideal for industrial bulk storage.

Engineered for Structural Strength and Operational Efficiency

Dry bulk solids tanks must withstand high vertical loads, uneven material distribution, and dynamic forces during filling and discharge. Center Enamel designs every tank in strict accordance with international standards, including AWWA D103, EN 1090, ISO 28765, and EUROCODE, ensuring safety and long-term structural stability.

Modular Bolted Construction

Center Enamel dry bulk solids tanks utilize a modular bolted design, offering key advantages:

Fast on-site installation without extensive welding

Easy transportation to remote or industrial locations

Flexible expansion or relocation as capacity needs change

Reduced foundation and civil construction requirements

This modular approach is particularly valuable for industrial projects with tight schedules and evolving operational demands.

Optimized Discharge and Flow Design

The smooth glass surface minimizes material adhesion, reducing issues such as:

Bridging and rat-holing

Material buildup and contamination

Downtime caused by cleaning and maintenance

This enhances operational efficiency and ensures reliable material discharge.
