Steel Water Storage Tanks: Durable, Corrosion-Resistant Solutions by Center Enamel
Reliable water storage is a vital part of modern infrastructure, supporting applications from potable water supply to industrial process water, fire protection, agriculture, and wastewater treatment. Among the diverse tank technologies available, Glass-Fused-to-Steel (GFS) tanks have emerged as a superior solution offering exceptional strength, corrosion resistance, and longevity. Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) leads in the design, fabrication, and delivery of high-quality GFS tanks engineered to meet stringent international standards and diverse customer needs worldwide.
Understanding Glass-Fused-to-Steel (GFS) Tank Technology
GFS tanks are constructed from structural carbon steel panels treated with a specially formulated glass enamel coating on both interior and exterior surfaces. The steel panels are precisely fabricated and then coated with glass frit, pigments, and binders. These panels are subsequently fired in high-temperature kilns (~820°C to 930°C) where molten glass fuses permanently to the steel, creating an impervious, smooth, and chemically inert surface.
The unique dance between glass and steel creates:
· A molecularly bonded coating offering unparalleled corrosion protection.
· A robust storage vessel retaining steel’s mechanical strength and flexibility.
· Surfaces resistant to abrasion, microbial growth, and chemical attack.
· Exceptional thermal stability and weather resistance.
Advantages of GFS Steel Water Storage Tanks
· Corrosion Resistance: Unlike traditional painted steel tanks, GFS tanks resist rust and chemical degradation even under aggressive water chemistries, extending operational life beyond 30 years without repainting.
· Structural Integrity: The steel core enables tanks to resist internal pressure, seismic, wind, and ground movement stresses, ensuring safe and secure water storage.
· Hygienic Surface: The non-porous glass layer inhibits algae, biofilm growth, and sediment accumulation, maintaining water purity with minimal chemical intervention.
· Modular Bolted Assembly: Off-site prefabrication of panels enables efficient onsite bolting for faster installation, transport, and maintenance.
· Environmental Sustainability: Composed of recyclable materials and produced with low environmental impact, contributing to circular economy principles.
· Versatility: Suitable for potable water, fire water, agricultural irrigation, industrial process water, wastewater, and rainwater harvesting.
· Global Standards Compliance: Meets ISO 9001, NSF/ANSI 61, AWWA D103-09, EN1090, WRAS, FM, LFGB certifications assuring performance and safety across international markets.
Center Enamel Manufacturing Excellence
Material Preparation
· Highest-grade hot-rolled steel plates are precision cut and surface prepared by sandblasting, eliminating contaminants and ensuring optimal enamel adhesion.
Glass Enameling Process
· Double-sided enameling applies a uniform 0.25-0.45 mm layer of vitreous glass enamel to all steel panels.
· Controlled kiln firing ensures permanent fusion creating a smooth, impervious coating robust against wear and environmental factors.
Panel Fabrication
· Panels are precision fabricated with drilled bolt holes and custom cutouts to client specifications, allowing flexibility and customization.
· Use of corrosion-resistant, plastic-capped bolts and silicone gaskets form leak-proof, durable seals during assembly.
Quality Control and Testing
· Panels and assembled tanks undergo rigorous inspections including spark testing (>1500V), adhesion strength testing (exceeding 3450 N/cm²), and corrosion resistance evaluations.
· Visual inspections and dimensional verifications ensure compliance with strict manufacturing tolerances.
Applications of GFS Steel Water Tanks
· Potable Water Storage: Ideal for municipal water supply and rural water schemes ensuring safe drinking water storage.
· Fire Protection Water: Secure reservoirs for fire suppression systems in commercial, industrial, and residential complexes.
· Agricultural and Irrigation Water: Providing vast reservoirs for reliable irrigation and livestock watering.
· Wastewater and Industrial Effluent: Resistant tanks for effective effluent containment and treatment processes.
· Rainwater Harvesting: Safe, large-volume tanks supporting sustainable water resource management.
· Food and Beverage Processing: Sanitized storage for process waters and ingredients requiring contamination-free environments.
· Chemical Storage: Compatible with a wide range of chemicals and process fluids thanks to high corrosion resistance.
