Glass-Fused-to-Steel (Glass-Lined-Steel) – GFS 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 te 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:
- Long life
- Low capital cost
- Low maintenance costs
- Rapid installation
- Ease of transport
- Flexibility to re-model, extend, dismantle and re-locate
Product Design Specifications
There are many steps are required for the production of high-quality panels for GFS tanks, silos and vessels. Our Tanks attach equal importance to each individual processing step in order to satisfy our customers high quality standards.
Enamel
Glass melted on steel offers best corrosion resistance and makes the product stable as well as elastic. Our Tanks offers enamelling on mono-, ultra- and uni-glass. The enamel powder is applied to the panels by electrostatic charging. In the furnace, the powder-coated panels are heated to approx. 800 °Celsius. The enamel powder melts in this process and forms a permanent connection to the metal surface. The resulting glass-like and extremely resilient enamel layer protects the entire steel surface permanently.
Foundation connection
The connection between the tank and the foundation is another important criterion we offers four connection systems:
- Ring groove
- Stabilising ring
- Flat foundation
- Deep rebate
Edges
We apply an edge protection to the edges by default, which is particularly important for panels that have not been de-burred. We conduct de-burring on request, during which the panels will be rounded off at the edges to achieve continuous enamelling.
Bolting
The special bolts used for joining the panels together are an additional advantage. We provide three variants:
- Galvanised tank bolt
- Tank bolt A2
- Tank bolt A4
Steel Enamel Roof
The roof carriers are installed on the outside of the roof. At the centre of the roof, they merge into the crown ring, at the container edge into the head angle.
Type of Roofs
- Geo Membrane type flexible roof
- Self-supported roof structure of hot-dip galvanised profiles
- Enamelled roof panels below the steel structure installed with special stainless steel screws
- PVC Tarpaulin type roof
- Double membrane roof
Access Ladder
- Material – hot dip galvanised
- Back protection
- Staircase Resting Platform
Insulation
- Standard insulation: 100 mm with mineral fibre mats
- Standard: hot dip Galvanized /coated steel-trapezoidal sheets
- Special: coated aluminium trapezoidal sheets
- Many Standard colours
Installation
- We have experienced manpower who installed 100+ GFS tanks world wide while using several installation methods. Below items to be confirmed before starting the Tank installations.
- Readiness of foundation
- Correct Inventory of Tank Panel for identification
- Tool & Tackles
- Manpower
Erection Methodology using Jacking System
- Tank erection is commenced building the top two bolted strakes with the use of installation jacking system at ground level.
- The top two strakes and roof is lifted & then the next strake is bolted into position & the procedure is continued. As the tank strakes are lifted, the accessories and appurtances are bolted to the tank shell until all strakes are bolted into position.
