Glass-Fused-to-Steel (GFS), also known as Glass-Lined-Steel (GLS), is the ultimate tank solution utilising a proven product with significant advantages.
The Glass-Fused-To-Steel-tank is assembled from special steel plates, special sealing materials, self-locking bolts and other materials. It can be used for the sealed storage of gases, liquids and solids in biogas engineering, sewage treatment, grain storage, petrochemical industries and other industries. In the biogas project, the assembled tank is a container for storage and fermentation of various organic substances.
Glass-Fused-to-Steel (Glass-Lined-Steel) is a unique tank finish. Two materials are fused together to achieve the best properties of both – the strength and flexibility of steel combined with the corrosion resistance of glass. Applied to both interior and exterior surfaces, Glass-Fused-to-Steel is able to provide many years of trouble free service in harsh environment.
This system has been proven over many decades on thousands of installations, and is supported by International Standards, which cover the design and finish requirements such as EN ISO/ ANSI AWWA/ EEA/ BS.
Glass-Fused-to-Steel finish combined with its modular design and build concept offers an array of benefits to contractors and users. Some of these include:
1. High temperature resistant sealant, anti-biological corrosion.
2. Stable quality, good anti-corrosion performance, long service life of the tank; and it has the characteristics of resistance to strong acid, strong alkali, and high temperature resistance.
3. High-strength self-locking bolts with rubber caps have good water-stop and anti-corrosion effects.
4. Fast installation, capacity expansion and migration: The assembled tank body is spliced by standard steel plates with bolts. The tank body can be dismantled or reinstalled after completion and operation, and the tank body can be easily expanded and moved.
Glass-Fused-To-Steel Tanks | Concrete Tanks |
Lower capital cost | Higher capital cost |
Manufacturing is completed in a certified controlled factory | Field Manufactured so uncontrolled variables such as worker experience |
Manufacturing is completed in the factory - reduced site clearing and levelling | Field Manufactured with large areas and clearing required - high capital cost |
Proven, excellent life cycle costing. | Construction specific, unknown life cycle costing |
Above ground, positive containment easy to see and inspect nothing to leak in | Below ground out of site out of mind unseen contamination in tank water loss through cracks |
The factory applied coating is permanent, impermeable and is chemically and mechanically bonded. No re-coating required | Concrete is permeable – coatings are required, ongoing maintenance and costs |
Built at ground level using lifting jacks and minimal equipment | Requires significant amount of site equipment & plant and working at height |
Durable, long lifetime coating, however in the event of damage, panels are replaceable | Spalling, cracking failures are difficult to remedy long term |
Maintains a capital value and can be relocated with minimal scrap | Significant demolition costs. Cannot be re-used or re-located |
Smooth hygienic glass surface, no effect on stored contents | Rough uneven surface attracts surface build up |
Glass coating more resistant to chlorine and chlorides | Chlorine treatment is very hard on the concrete, coatings and reinforcement |
Less dependent on weather for successful construction | High temperatures can cause premature drying and cracking during construction |
Tanks can be made expandable vertically with no change in footprint, so great for growth | Not expandable - Increasing capacity requires significant engineering |
The tank kits can be easily transported and assembled in tight locations | Limited and difficult for projects in tight locations |
Easily adaptable using bolted connections to add baffles, mixing systems and equipment | Significant engineering required for tank changes and accessories. |
Foundation designed for any soil condition | Poor soils / high water |
Graffiti and debris easily wiped or washed off | Concrete needs repainting, difficult to clean |
Aesthetically more pleasing | Chalking and fading possible - exterior coating to prolong the concrete appearance |
Range of colours available to meet environmental or aesthetic requirements | Concrete has limited aesthetics |
