Glass-Fused-To-Steel vs Concrete Tanks

Mar. 24, 2022

What Are Glass-Fused-To-Steel Tanks (GFS Tanks)?

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.

Why Choose Glass-Fused-To-Steel Tanks?

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
No fading, chalking or discolouring which is great for community projects

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
