GFS Fertilizer Tanks: Reliable Solutions for Efficient Fertilizer Storage and Handling

Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) is a leading manufacturer of Glass-Fused-to-Steel (GFS) tanks, renowned for delivering highly reliable, corrosion-resistant, and cost-effective fertilizer storage solutions worldwide.

GFS fertilizer tanks employ innovative Glass-Fused-to-Steel technology, where molten glass coats steel plates at temperatures between 820°C and 930°C, creating a robust bond that combines steel’s mechanical strength with glass’s exceptional corrosion resistance. This manufacturing technique ensures tanks resist harsh chemical environments, including fertilizers like urea-ammonium nitrate (UAN), ammonium sulfate, and other liquid or slurry fertilizers with variable pH levels.

The tanks are composed of modular bolted panels, providing flexibility and ease of installation on-site, significantly lowering construction time and costs compared to traditional welded steel tanks or fusion bonded epoxy tanks.

As a leading storage tank manufacturer worldwide. Center Enamel can provide Glass Lined Steel(GLS) tanks, fusion bonded epoxy tanks, stainless steel tanks, galvanized steel tanks and aluminum geodesic dome roofs, Wastewater and Biogas Project Equipments for global customers.

Manufacturing Process and Quality Assurance

Center Enamel’s manufacturing process integrates nearly 200 patented enameling technologies and advanced quality control protocols:

• Steel Plate Preparation: Premium hot-rolled steel plates are first cleaned and prepared to receive the enamel coating.
• Double-Sided Enameling: The steel is coated evenly on both sides with a glass powder, then fired in specialized kilns reaching up to 930°C. This vitrification bonds the glass permanently to the steel.
• Panel Fabrication: The enamel-coated steel plates are formed into panels, which undergo rigorous testing including adhesion strength tests (3450N/cm²), hardness (Mohs scale 6), and holiday testing with up to 1500V to spot coating defects.
• Sealing and Assembly: Bolted with specialized gaskets and seals for leak-proof performance, the modular tanks are shipped and assembled on-site.

These quality checkpoints ensure a service life of over 30 years, unmatched corrosion protection for acids and alkalis (pH 3 to 11 standard, extendable pH 1 to 14), and resistance to gas and liquid permeability. The tanks are also UV and weather resistant, making them suitable for outdoor exposure.
