GLS tanks are Glass Lined Steel tanks, also known as Glass-Fused-to-steel tanks (GFS Tanks). The reason for fusing glass with steel is to enhance the properties of the latter. Single Steel is vulnerable to environmental conditions, hence the fusion is required. After fusing the steel with glass, the strength increases, the acceptable bracket of PH value for alkaline solutions widens, and the resistance of abrasion inflates.
We also offer Glass fused to steel tanks as per the RTP technology and fire protection water storage tanks which meets FM Global & other industry standards.
The Glass Fused to Steel tank panels is lined inside and outside with the glass enamel. The enamel is a solid, smooth and shiny cover of silicate. It is fused in a special furnace having temperature ranges from 780 to 900 degree Celsius. The Steel rounded (cylinder) shell of the tank is built from two-layer glass-fused sheet coated on both the sides. The sheets are attached with special high-grade bolts and sealed by constantly flexible silicones (sealants). The connecting material and shell accessories are equipped with surface treatment. The glass-fused tanks can be used to store fluid or lose material. The specialty of these tanks is that they are FM Global approved & can be used as an industrial water storage tank. The GFS/GLS tanks are also a fundamental building element of environmental technological facilities such as Waste Water Treatment, Fire fighting Water storage and Anaerobic Digester Tank.
Every sheet is checked in the manufacturer’s plant for the enamel layer completeness by using the POROSCOPE (DEZ 4.13) and PINHOLE (DEZ 4.12) test according to DIN ISO 2746. The chemical resistance and physical properties are also tested according to DIN and they comply with the highest quality requirements according to the methodology by the German Enameller’s Association (DEZ). Other than that our FM Global approved tanks are best for industrial usage.
Glass coated sheets can be delivered in four standard colors; Green (RAL 6009), Brown (RAL 8017), White (RAL 9000), and Blue (RAL 5013).
