What is Glass-Fused-to-Steel?

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 environments.
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:

EN ISO 28765:2011:  “Vitreous and porcelain enamels – Design of bolted steel tanks for the storage or treatment of water or municipal or industrial effluents and sludges”

ANSI / AWWA D103-09:  AWWA Standard for “Factory-coated bolted steel tanks for water storage”

EEA 7.20, EEA 7,24, EEA 7.25:  “Vitreous enamel coated bolted steel tanks / silos”

BS 5502:  “Buildings and structures for Agriculture”

NRCS:  Slurry tank design approval for waste storage structures in the USA.

The modular bolted tank construction principal allows the “factory – quality” finished panels to be economically shipped to site and erected within very tight timescales.

PERMASTORE® tanks are manufactured and tested in accordance with these and other standards as required. In addition, all of Permastore’s finishes are produced in accordance with published Quality Standards giving reassurance of a consistently secure storage solution.
Permastore Quality Standards are also independently audited by MPA NRW (a state owned testing company based in Germany) to ensure that the Quality Standards are consistently maintained.  The contact surface of all industrial tank panels are high voltage tested to ensure zero discontinuities.

Permastore’s Glass-Fused-to-Steel finish combined with its modular design and build concept offers an array of benefits to contractors and users. These include:

  • Long life
  • Low capital cost
  • Low maintenance costs
  • Rapid installation
  • Ease of transport to site
  • Flexibility to re-model, extend, dismantle and relocate
