What is Glass-Lined-Steel?
Glass-Lined-Steel/Glass-Fused-to-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:
- International Quality Management Standard – ISO 9001:2008 accreditation of quality standards to guarantee Customer satisfaction.
- International Standards – Permastore’s quality systems ensure that products meet or exceed the requirements of EN ISO 28765:2016*, AWWA D103-09, EEA 7.20, 7.24 and 7.25 amongst others.
