Glass-Fused-to-Steel Tanks

Adhesion between two materials

Glass-Fused-to-Steel-Tanks (GFS), also called Glass-Lined-Steel tanks, are steel tanks fused with glaze enamel at 800°/ 900°C, to become a new material called Glass-Fused-To-Steel – the joint between the enamel and the steel is in a molten state, ensuring perfect and total adhesion between these two materials.

Tank durability

This is a leading high-tec solution that combines the strength and flexibility of the steel with the high corrosion-resistance of the glass, significantly enhancing the tank’s durability since both sides of each panel are GFS.

Geodesic dome roof

High-quality bolts and sealants are used to assemble the Glass Fused Steel tank panels. Surface treatment is applied to the tank’s accessories, while the content of the tank itself is sealed from the external environment with a geodesic dome roof.

High strength Titanium Rich Steel (TRS)

High strength Titanium Rich Steel (TRS), the material from which premium GFS tanks are built, is inherently robust and flexible while the glaze is resistant to the damaging effects of corrosion.

Glass-Fused-To-Steel tanks have the following benefits:

  • Excellent anti-corrosion performance
  • An extended tank life
  • Rapid installation
  • Premium quality: design, production and quality control standards
  • Able to withstand harshest environmental conditions
  • Wind load: 60m/s
  • 30 year life-span
  • Low maintenance 
  • Easy to repair
  • Possible to relocate, expand and reuse
  • Visually appealing

Low maintenance 

Corrosion resistance provided by Glass-Fused-to-Steel-Tanks reduces maintenance costs because corrosion causes tank damage that results in maintenance costs.

Construction is a rapid process

Modular bolted Glass-Fused-to-Steel-Tank construction is a rapid process. This reduces project costs because it reduces project timelines.

Extend and dismantle

Glass-Fused-to-Steel-Tanks extend and dismantle, whereas other square, plastic, or concrete tanks cannot. This reduces the cost of relocating the tank between sites.

Reliable and secure bulk water storage

Glass-Fused-to-Steel-Tanks provide safe, reliable and secure bulk water storage. Since they are completely sealed-off from the environment, there is no ingress of dust, dirt, insects or even light –  no light, no algal growth. This ensures clean, potable water to households and businesses in challenging times.

Clean Water

Securing clean water is essential during times of drought and flood. It provides the lifeblood to any populace. Water tanks are an essential part of water storage – unlike open surface dams, reservoirs, pits, wells or rivers, the contents of water storage tanks can easily be monitored for water potability.

It is therefore essential that when selecting a tank, it is both resilient and durable and able to provide water that is safe to drink.

Glass-Fused-Steel-Tanks in summary:

Glass-Fused-Steel-Tanks are the preferred solution for the storage of meg-volumes of water or liquid – potable water storage, waste water treatment, fire-fighting, industrial, commercial, for-processing, agriculture, emergency water supply, township water supply, rural or community water supply, etc.

The tests done on GFS tanks comply with the highest quality requirements to ensure that they are ecologically safe and reliable. Some international standards and certifications of our GFS tanks:

AWWA D103 (American Water Works Assoc.)

EN ISO 28765 (Vitreous and Porcelain Enamel Bolted Steel Tanks)

NFPA 22 (Standards for Private Fire Protection – USA)

OHSA PT.1910 (Federal Standards Testing Labs)

ISO 9001:2015

NSF/ANSI 61 (National Sanitation Foundation, USA – the only American National Standard addressing the human health effects of drinking water system components. … This standard forms the basis of the regulatory framework and of public health protection for controlling the health effects of drinking water contact materials across the USA and Canada.)
