Understanding Glass Fused to Steel Technology

GFS technology combines the strength and structural integrity of steel with the corrosion resistance and hygienic qualities of glass enamel. The manufacturing process fuses a special glass enamel coating onto high-grade steel panels at extremely high temperatures (820°C to 930°C), creating a permanent, inert, and smooth vitreous surface.

This fusion results in tanks that offer:

• Outstanding corrosion and chemical resistance, crucial for storing rainwater that may contain acids and organic matter.
• Hygienic, smooth interiors that prevent bacterial and algae growth.
• Long-term durability and resistance to harsh environmental conditions.
• Maintenance-free operation with no need for periodic repainting or lining.

Why Choose GFS Tanks for Rainwater Recovery?

Rainwater tanks must remain uncontaminated, structurally sound, and durable under fluctuating weather and water quality conditions. GFS tanks are ideally suited to this role because they:

• Withstand acidic rainfall and environmental pollutants better than traditional steel or plastic tanks.
• Provide robust structural strength capable of withstanding seismic, wind, and snow loads.
• Feature UV-resistant coatings, ensuring that tanks do not degrade under prolonged sun exposure.
• Offer modular construction and bolted assembly for flexible installation and scalability.
• Help maintain high water quality by preventing contamination and biofilm build-up.

Technical Specifications of Center Enamel GFS Rainwater Tanks

Center Enamel manufactures GFS rainwater tanks adhering to rigorous global standards such as ISO 9001, AWWA D103, NSF/ANSI 61, and FM. Typical specifications include:

Features and Innovations

• Aluminum Alloy Trough Deck Roofs: Designed to efficiently channel accumulated water into the tank while resisting corrosion, the lightweight yet strong aluminum alloy roofs improve tank longevity and performance.
• Modular Design: Tanks consist of pre-coated modular panels easily transported and assembled onsite, enabling customized tank sizes and facilitating future expansion.
• High-Performance Sealants and Gaskets: Ensure leak-proof joints for maintaining water quality and preventing contamination.
• Environmental Resistance: Tanks are engineered to resist UV radiation, wind loads, seismic events, and temperature fluctuations.
• Ease of Maintenance: Smooth glass coating resists algae and bacteria, allowing for easy cleaning with minimal labor.

Applications of GFS Rainwater Recovery Tanks

• Residential Water Harvesting: Save water and reduce utility bills by using stored rainwater for irrigation, flushing, and laundry.
• Commercial Buildings: Provide sustainable water solutions supporting greywater systems, landscaping, and fire protection.
• Agricultural Irrigation: Reliable water source for crops and livestock, especially in arid or drought-prone regions.
• Municipal Water Supply: Supplement public water systems, reduce stormwater runoff, and improve urban water resilience.
• Industrial Process Water: Capture rainwater for cooling, washing, and other non-potable industrial uses.

Environmental and Economic Benefits

• Water Conservation: Promotes responsible water use by capturing natural rainfall and reducing demand on freshwater supplies.
• Reduced Energy Usage: Transports and stores rainwater locally, reducing energy-intensive pumping and treatment of mains water.
• Longevity and Durability: Extensive service life reduces replacement costs and environmental impact.
• Reduced Maintenance Costs: Corrosion and abrasion resistance minimize repairs and downtime.
• Support for Sustainable Development Goals: Enables compliance with global environmental standards and regulations.
