Glass-Fused-to-Steel Tanks - Rainbow Reservoirs

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.

With competitive price and timely delivery, Wansheng sincerely hope to be your supplier and partner.

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.

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:

These Are Some Of The Most Interesting Benefits of Using Glass Fused Steel Tanks

Rostfrei Steels Glass Fused Steel Tanks are one of the best Liquid Storage Tanks and here are the benefits of using Glass Fused steel tanks.

Glass-lined equipment is basically a corrosion resistant material which is used in different processes of operations and they are considered to come with tons of benefits also. They are used in a variety of processes, from the production of different pharmaceuticals to specialty polymers and chemicals, glass lined equipment have found their way into operations of these processes. This super strong glass-lined equipment is known for putting different materials in safe-zones, that are exposed to harsh materials like alkalis, acids, water and other chemicals, from becoming corroded and eventually causing failure within the pressure equipment.

Due to all of these benefits of glass-lined equipment, they are considered to be a type of equipment that can help in giving different materials a particularly long service life, even when they are present in environments where service conditions are difficult and other equipment would quickly become unfit for service.

In addition to being resistant from corrosion, glass lined equipment is also resistant to contamination from dissolved alloys or metals. These materials can easily turn any equipment into damaged metal parts. Apart from all of this, this equipment is able to handle a diverse range of operating conditions and it is also much easier to clean than unlined equipment. Glass-lined equipment is a major part of Glass Fused to steel tanks, which is why more and more people are opting for them since there are so many benefits of using Glass Fused Steel Tanks. Even though glass lined equipment is a bit expensive than unlined equipment on the forefront but eventually, they turn out to be more cost-effective in the long run, because of its increased service life.

Why should one go for Rostfrei Steels Glass Fused Steel Tanks?

Currently, Glass-Fused-to-Steel technology is considered to be one of the most premium products in the water storage tanks. Rostfrei Manufacturing’s team chooses glass lined tanks over an ordinary tank design for a lot of reasons, some of them are:
