Product Description
Glass-Fused-to-Steel tanks (GFS tanks), also known as glass-lined steel tanks (GLS tanks), are an advanced storage tank solution. They are produced by firing at a high temperature of 820°C-930°C, causing the molten glass to react with the surface of the steel plate. This process fully leverages the optimal performance of both materials, forming a robust and corrosion-resistant bond. The technique seamlessly combines the strength and flexibility of steel with the excellent corrosion resistance of glass, enabling Glass-Fused-to-Steel tanks to provide years of service in harsh environments. Compared to traditional fusion bonded epoxy tanks or welded steel tanks, GFS tanks have several advantages. We also offer various accessories to meet the needs of your facility, such as manholes, flanges, top cover handles, tank maintenance ladders, and platforms.
Glass-fused-to-steel technology is an advanced coating technology in the tank market. The molten glass coating endows the product with outstanding corrosion resistance and wear resistance, validated through decades of installations. The modular bolted connection design of GFS tanks makes them more economically efficient in on-site installation. and Shijiazhuang Zhengzhong Technology Co.,Ltd Glass Fused to Steel tanks (GFS tanks)conform to AWWA D103-09, OSHA, ISO 28765, NSF/ANSI 61, NFPA and other international standards , and are widely used in bio-energy, municipal sewage, landfill leachate and industrial wastewater treatment etc. applications
