GLS Potable Water Tanks by Center Enamel: Setting the Global Standard for Safe, Sustainable, and Hygienic Water Storage
Access to clean potable water is a fundamental human right, and secure water storage is essential in supporting public health, economic development, and environmental sustainability. Around the globe, communities, municipalities, and industries increasingly turn to advanced GLS Potable Water Tanks—also known as Glass-Lined Steel or Glass-Fused-to-Steel (GFS) tanks—for the safe, long-term containment of drinking water. At the cutting edge is Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), a pioneer that combines over three decades of engineering innovation, scientific research, and manufacturing excellence to deliver premium potable water storage solutions that redefine industry standards.
GLS tanks harness the combined durability of steel and the inert, corrosion-resistant nature of glass. Their construction involves thermally fusing a specially formulated glass layer to both sides of high-strength steel plates at temperatures reaching up to 930°C. This fusion produces an enamel layer that is chemically and physically bonded to steel, rendering the finished tank impervious to corrosion, leaching, and environmental degradation.
Key Scientific Advantages:
· Superior chemical resistance: Withstand aggressive chemicals, chlorinated water, and extreme pH conditions (pH 1–14 with special coatings).
· Surface inertness: The glass lining remains non-reactive, ensuring absolutely no taste, color, or odor is imparted to water.
· Non-porous barrier: Prevents bacterial colonization, biofilm build-up, and mineral scaling.
GLS tanks from Center Enamel are built for hygiene and purity, passing rigorous international water quality regulations, including:
· NSF/ANSI 61 (USA): Certifies materials for use in potable water systems.
· WRAS (UK): Water Regulations Advisory Scheme approval for drinking water.
· ISO 28765: The international standard for the design and manufacture of vitreous enameled bolted steel tanks.· AWWA D103-09
· CE Mark, ISO 9001: Certified for global export and quality assurance.
GLS tanks’ smooth, glassy surfaces guarantee water safety, making them ideal for cities, rural systems, emergency water storage, resorts, industries, and critical public facilities.
Center Enamel’s patented bolted-panel technology makes GLS tanks especially attractive for their:
· Modular Assembly: Pre-fabricated panels, shipped compactly, are rapidly bolted together onsite.
· Quick Installation: Erection time is up to 50% faster than for poured concrete or welded steel tanks.
· Minimal Site Impact: No heavy welding or painting reduces disruption and lowers carbon footprint.· Scalability:
Tanks are easily expanded or relocated as capacity needs grow—or reassembled at entirely new locations.
Installation is feasible even in challenging or remote regions, supporting disaster relief, rural water systems, and urban expansions with equal facility.
GLS potable water tanks offer over 30 years of design life—significantly outlasting concrete, plastic, or epoxy-lined alternatives. Unlike traditional tanks, which suffer from rust, liner degradation, UV attack, or cracking, GLS tanks:
· Require no repainting, recoating, or sealing;
· Withstand temperature extremes, freeze-thaw cycles, and harsh sunlight (UV resistance prevents fading and chalking);
· Maintain color and surface integrity, with anti-graffiti surface options.
Routine inspection and cleaning are simple, allowing for uninterrupted, low-cost operation and guaranteeing robust asset longevity.
The fused glass enamel barrier eliminates steel contact with water and the atmosphere. This provides:
· No corrosion or rusting even in coastal, saline, or chemically aggressive environments.
· No leaching of metals—critical to compliance with safety limits for lead, iron, and other hazardous substances.· Protective self-healing
—the glass layer prevents under-coating migration of rust, while minor scratches have no effect on longevity.
Enamel layers are tested above 1500V for pinholes or breaches, guaranteeing total impermeability to gas and liquid, ensuring zero ingress or egress of external contaminants.
Center Enamel custom engineers every GLS tank, offering:
· Diameters up to 60+ meters and heights over 30 meters for capacities from <10 m³ to >60,000 m³.·
Aesthetic color options (cobalt blue, forest green, white) for seamless environmental integration, blending tanks into landscapes or cityscapes.
· Roof selections: aluminum dome, GFS panel, or insulated membrane for potable water protection or biogas applications.·
This complete flexibility means Center Enamel tanks are at home from bustling city centers to desert outposts, from industrial megasites to eco-friendly resorts.
· The modular GFS system vastly reduces on-site waste and energy consumption versus traditional tanks.
· All tank components are fully recyclable at the end of the service life.
· Leak-free storage protects aquifers and surface waters, underpinning sustainable water management strategies.
· Costs are front-loaded and predictable, with minimal future maintenance obligations.
· Modular construction enables phased investment and expansion as community or industrial demands increase.
· Fast delivery and installation lower project critical path times, allowing faster commissioning and revenue realization.
Center Enamel’s GLS Potable Water Tanks are trusted in over 100 countries—including high-profile municipal, utility, industrial, and emergency storage projects in Asia, Africa, Europe, Australia, and the Americas.
Recent projects highlight:
· Megacity upgrades in Malaysia, Ghana, and Indonesia (20,000 m³+ tanks for urban networks).
· Rural and resilient infrastructure in South America and Africa (custom tanks for difficult-to-access water-stressed regions).· Industrial and commercial systems for beverage, hotel, and property groups
Every Center Enamel GLS tank passes rigorous pre-shipment and post-installation checks, including:
· 1500V holiday spark tests to check for micro-defects in enamel coverage
· Adhesion and thickness measurements to ensure structural strength and chemical resistance.
· Design simulations for seismic, wind, snow, and operational pressure (using FEM modeling).
· Material certifications for all gaskets, bolts, and accessories (food-grade standards).
With over 30 years of tank manufacturing history, Center Enamel is distinguished by:
· Proven engineering and innovation capacity;
· Commitment to research, digital integration, and continuous process improvement;
· Dedicated teams for global project execution, from design consultation and fabrication to on-site assembly and after-sales support.
