Description

Glass-Fused-to-Steel (GFS) Bolted Tanks are engineered storage systems manufactured by fusing a specially formulated glass coating to steel panels at high temperatures above 800°C. This process combines the strength and flexibility of steel with the superior corrosion resistance of glass, creating a durable and chemically stable tank solution for demanding storage environments.

As a core product under the Bolted Tanks system, GFS Bolted Tanks are widely specified in municipal, industrial, and environmental infrastructure projects where long service life, minimal maintenance, and reliable performance are critical.

Key Engineering Advantages

• Glass–Steel Fusion Technology–Permanent fusion ensures coating integrity and eliminates under-film corrosion.
• Excellent Corrosion Resistance–Suitable for aggressive liquids, variable pH, and harsh climates.
• Long Design Life–Engineered for decades of continuous operation.
• Modular Bolted Construction–Fast on-site installation and future capacity expansion.
• Factory-Controlled Quality–Panels manufactured and tested under strict QA/QC procedures.
• Low Maintenance Requirement–No on-site coating or welding required.

Typical Storage Media

• Potable and non-potable water
• Wastewater and treated effluent
• Sludge and biosolids
• Industrial process liquids
• Leachate and chemically aggressive fluids

Coating Technology

The glass coating is applied by spraying molten glass onto prepared steel panels, followed by firing in a controlled furnace. The result is a smooth, inert, and non-porous surface that resists corrosion, abrasion, and chemical attack.

Key coating characteristics include:

• Uniform thickness and adhesion
• Resistance to UV exposure
• Stable performance under temperature fluctuations
• Compliance with international coating standards
