Center Enamel Glass Lined Steel Tanks for Potable Water Storage

Water is an essential resource for human survival, and ensuring the safe storage of potable water is a critical concern worldwide. With growing urbanization, industrialization, and climate challenges, the need for reliable and long-lasting water storage solutions has increased. Center Enamel, a leading manufacturer of bolted storage tanks, offers Glass Lined Steel (GLS) Tanks as an innovative solution for potable water storage. Our Glass-Fused-to-Steel (GFS) technology ensures durability, safety, and superior performance, making our tanks the preferred choice for municipal and industrial water storage applications worldwide.

What are Glass Lined Steel Tanks?

Glass Lined Steel Tanks, also known as Glass-Fused-to-Steel (GFS) Tanks, are bolted steel tanks coated with a layer of glass enamel. This advanced coating is applied using high-temperature fusion, creating a durable bond between the glass and steel. The result is a non-porous, smooth, and highly corrosion-resistant surface, making GLS tanks ideal for potable water storage.

As a leading storage tank manufacturer worldwide. Center Enamel can provide Glass Lined Steel(GLS) tanks, fusion bonded epoxy tanks, stainless steel tanks, galvanized steel tanks and aluminum geodesic dome roofs, Wastewater and Biogas Project Equipments for global customers.

Advantages of Center Enamel Glass Lined Steel Tanks for Potable Water Storage

1. Superior Corrosion Resistance

The combination of glass and steel creates a chemically resistant barrier that prevents corrosion from water impurities, chemicals, and environmental conditions. Unlike traditional welded tanks that require regular maintenance and recoating, GLS tanks offer long-lasting performance without degradation.

2. Hygienic and Safe for Potable Water

Center Enamel’s Glass-Fused-to-Steel tanks comply with international water storage standards such as NSF/ANSI 61, WRAS, ISO 28765, and AWWA D103-09. The glass coating ensures a smooth, non-porous surface that prevents bacterial growth, safeguarding the quality of stored potable water.

3. Long Service Life

With a design life of over 30 years, Center Enamel GLS tanks are built to withstand harsh environments while maintaining structural integrity. The glass coating protects the steel from oxidation, rust, and external contaminants, ensuring a long service life with minimal maintenance.

4. Modular and Expandable Design

The bolted panel construction allows for easy transportation and installation at remote or challenging sites. Unlike welded tanks, GLS tanks can be disassembled, relocated, or expanded, offering greater flexibility to accommodate growing storage needs.

5. Quick Installation and Cost Efficiency

Center Enamel GLS tanks use a modular bolted assembly system, which significantly reduces on-site installation time compared to traditional concrete or welded steel tanks. The pre-fabricated panels ensure faster construction, reducing labor costs and project downtime.

6. UV Resistant and Aesthetic Appeal

The glass coating provides UV resistance, preventing fading or chalking even under prolonged sunlight exposure. Center Enamel offers a range of custom colors to match the surrounding landscape, making GLS tanks suitable for both urban and rural installations.
