GFS bolted tank is made of glass fused to steel plate, special sealing material, self-locking screw and other materials. The thickness of enamel steel plate can reach to 20 mm, the most used steel plate thickness is 3~10 mm, steel plate has surface oil, contain rust, contain oxide skin, after shot blasting, sand and other pretreatment process, the steel plate surface will be clean. After 900 ºChigh temperature second enamelingl in electric furnace ,0.3 mm enamel coating is applied on both sides of steel plate. strong binding force between enamel coating and steel plate. Enamel coating can not only prevent tank corrosion, but also has the function of strong acid and alkali resistance. And has extremely strong wear resistance.
Glass-fused-to-steel Tank refer to glass-lined storage tanks, also known as some GFS storage tanks.
Glass is melted with steel to enhance its performance.
Fusion is important because it is single steel, and it is the same for the environment.
When the fusion of steel and glass is completed, the strength increases and the wear resistance decreases, as does the suitable pH value scaffold for alkaline solution.
Such ponds are generally considered to be one of the important components of environmental technologies, such as anaerobic digestion tanks, wastewater treatment and fireproof storage.
They are industrial water storage tanks.
The glass fused on the stainless steel tank panel is coated with glass enamel inside and outside.
The enamel has a strong, bright, smooth silicate coating.

Glass Fused-To-Steel Tank Applications:
There Are Several Advantages to Using a GFS Bolted Tank:
Advantages of GFS bolted tanks
Compared with concrete or carbon steel welded tanks, the advantages of GFS Steel bolted tanks are listed below:
Low Cost
The installation, disassembly, migration, and resettlement of GFS bolted Tanks are convenient and fast, and do not require a large amount of labor and large installation equipment. The quality is stable and the corrosion resistance is excellent, so the maintenance cost is very low. Carbon steel welded tanks and concrete tanks are installed on-site and usually involve sealing and waterproofing, long installation intervals, and the installation process are easily delayed due to bad weather (such as rain or wind), resulting in high installation costs. In some cities, there may be restrictions on the use of sealants, resulting in delays or high installation costs. GFS tanks are more convenient and environmentally friendly without on-site finishing.Superior Corrosion Resistance
After the enamel steel plate is sintered at a high temperature of 820°-930°, the enamel will fuse with the surface of the steel plate to form a strong chemically inert inorganic coating, which has superior corrosion resistance.Short Construction Period
The Glass-Fused-to-Steel is standardized in the factory and is packaged and transported to the construction site for assembly. The steel plate is spliced by a bolt connection and has special installation tools for installation. The installation process is less affected by the weather and the installation cycle is easy to control.Freely Expandable
Compared with concrete or carbon steel welded tanks, the GFS tank has unmatched expandability. If it is necessary to expand the tank capacity in the future, the GFS tank can be easily expanded with minimal material and labor input. Since the Glass-Fused-to-Steel bolted tanks are constructed of modular enamel steel, only more enamel steel is needed and the time to reconfigure and expand existing tanks is required.
Beautiful Appearance
The surface of Glass-Fused-to-Steel bolted tanks is smooth and sleek, the standard color is dark blue, bright and beautiful, and any other colors can be customized according to the user's requirements.
