GFS Tanks with Double Membrane Roof Used in Biogas Engineering Projects

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.
