GFS tanks, short for "Glass-Fused-to-Steel Tanks," are advanced storage tank structures. The term "Glass-Fused-to-Steel" reflects its material characteristics, combining the strength of steel with the corrosion resistance of glass. GFS tanks are created by fusing special glass powder to the surface of the steel body, forming a robust, corrosion-resistant glass layer tightly bonded to the steel. This structure imparts corrosion resistance, high strength, and a long lifespan to the tank.

Outer Layer: The outer layer of GFS tanks is a glass layer that provides excellent corrosion resistance and a smooth surface. This glass layer typically consists of borosilicate glass powder and various additives to ensure durability.

Middle Layer: The middle layer is the steel body, providing structural support and strength to the tank. The steel is high-quality carbon steel, treated with processes like hot-dip galvanization to prevent corrosion.

Inner Layer: The inner layer, also composed of glass, forms a smooth, non-contaminating surface for liquids. This helps maintain the purity of the liquid stored in the tank.

The structural design of GFS tanks ensures outstanding performance in the face of different liquids and environmental conditions, making them an ideal choice for various liquid storage applications.
