Storage tanks
Superior Corrosion Resistance for Water & Food-Grade Use
GFS panels combine the structural strength of steel with the superior corrosion resistance of glass, fused together at 1500 to 1650 degrees Fahrenheit. The result is a smooth, anti-bacterial, low-maintenance storage surface.
Request a Quote / EnquireThe SAGOSI Glass-Fused-to-Steel (GFS) tank combines the structural strength of steel with the corrosion resistance of glass, fused together at 1500 to 1650 degrees Fahrenheit to form a smooth, cohesion-less, anti-bacterial storage surface. Designed to the ANSI AWWA D103-09 standard and certified for drinking water and food-grade applications, GFS bolted storage tanks are ideal where water quality, hygiene and long service life all matter.
Unlike welded or epoxy-coated tanks, a GFS tank requires no on-site welding and no periodic recoating — the glass surface will not rust, corrode or support bacterial growth, and individual panels can be repaired or replaced on site. Capacities range from 27 m³ to over 6,000 m³, and the bolted construction means the tank is relocatable and expandable. For potable water reservoirs, fire water, aeration and effluent duty, GFS delivers one of the lowest lifecycle costs in bolted steel storage.

A GFS tank is built from steel panels with a glass layer fused to the steel at 1500 to 1650 degrees Fahrenheit. The result is a panel that has the strength of steel and the corrosion and chemical resistance of glass.
Yes. SAGOSI GFS tanks are certified for drinking water and food-grade applications. The smooth, cohesion-less glass surface is anti-bacterial and does not leach into the stored liquid.
GFS bolted storage tanks are available from 27 m³ to over 6,000 m³, with diameter and height configured to suit the site footprint and head requirement.
The glass layer on a GFS tank is fused into the steel and will not chip, peel or need recoating, whereas epoxy coatings degrade over time. GFS is the premium choice for potable water; our micro-coated tank is a strong value alternative.
