Glass Fused to Steel Bolted Tanks

Anaerobic Digestion / Biogas


Glass-Fused-to-Steel (GFS) is glass that has been fired (heat-processed) in a kiln at a range of high temperatures ranging from 760ºC (1400ºF) to 860ºC (1580ºF) which facilitates the interfacial fusion reactions that combine the two materials. For there to be a fusion of two materials there must be a chemical bond at a molecular level. PERMASTORE® is the market leader in the manufacture and supply of Glass-Fused-to-Steel Tanks and Silos. Since 1959 the Company has been providing durable and cost effectively engineered containment solutions in Municipal, Industrial and Agricultural environments worldwide.

PERMASTORE® produces four distinct glass fused to steel FUSION® processes that allow engineered solutions to account for the most detailed specifications:

Epoxy Coated Climate Tanks™ offer the premier epoxy coatings from Permastore, who has joined forces with Akzo Nobel who is a leading global producer of paints and coatings. The result is an innovative, technologically advanced Fusion Bonded Epoxy product, FUSION® V1100, for modular, bolted containment systems. The high-tech RESICOAT® R4-ES used on the internal surface combined with the ultra-durable INTERPON® D2525 on the external surface sets the new benchmark within its sector. Following extensive research, with shared know-how and combined with our considerable experience in Glass-Fused-to-Steel solutions coating technology, we have developed FUSION® V1100 to be an exceptional Fusion Bonded Epoxy coating system, second only in performance to PERMASTORE® Glass- Fused-to-Steel solutions. Permastore uses high quality grades of sheet steel which meet or exceed the requirements of relevant tank design standards and applicable International Standards e.g., AWWA D103-09, EN 10025, EN 10149 and ASTM A1011. With the engineering expertise and experience gained from over 50 years in the global tank and silo industry, you can be assured that the FUSION® V1100 product offers the best quality, high performance Fusion Bonded Epoxy product which is installed with the precision and ease our customers have come to expect and value from the current PERMASTORE® product. Exporting to over 110 countries and supplying in excess of 300,000 durable and cost effectively engineered structures worldwide, Permastore has the knowledge and experience to provide the best possible solution for your specific application. The combination of Akzo Nobel’s market leading Fusion Bonded Epoxy coating formulation and Permastore’s unmatched factory application process has led to the innovative FUSION® V1100 Bonded Epoxy coating. The proprietary FUSION® V1100 Epoxy coating leads the market within its sector and is suitable for the storage, processing and general containment of a range of liquids. Factory-applied coatings eliminate weather delays typical of site-applied coatings, making FUSION® V1100 undoubtedly your best choice to suit your specific application. FUSION® V1100 gives you the assurance and dedication to the highest quality associated with the PERMASTORE® brand. The internal contact surface of every panel is subject to 100% factory inspection and testing at 1100v showing our commitment to zero discontinuities (defect free at test voltage). The external surface of the panel is inspected using a colorimeter test and the color checked against standard limits. Panels with a color outside of these limits will be rejected.

Weathered Finish Steel, often referred to by the generalized trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting and form a stable rust-like appearance if exposed to the weather for several years. Weathering refers to the chemical composition of these steels, allowing them to exhibit increased resistance to atmospheric corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence of the weather.

The corrosion-retarding effect of the protective layer is produced by the distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the protective coating; all of these Climate products are delivered un-patinated. It is very widely used in marine transportation, in the construction of intermodal containers as well as visible sheet piling along recently widened sections of London’s M25 motorway. The first use of weathering steel for architectural applications was the John Deere World Headquarters in Moline, Illinois. The use of weathering steel was seen as a cost-cutting move in comparison with the contemporary railcar standard of stainless steel. Weathering steel was used to build the exterior of Barclays Center, made up of 12,000 pre-weathered steel panels engineered by ASI Limited & SHoP Construction. The New York Times says of the material, “While it can look suspiciously unfinished to the casual observer, it has many fans in the world of art and architecture.”

Powder Coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating metals, such as household appliances, aluminum extrusions, drum hardware, and automobile and bicycle parts. There are two main categories of powder coating: thermosets and thermoplastics. The thermosetting variety incorporates a cross-linker into the formulation. When the powder is baked, it reacts with other chemical groups in the powder to polymerize, improving the performance properties. The thermoplastic variety does not undergo any additional actions during the baking process as it flows to form the final coating. The most common polymers used are polyester, polyurethane, polyester-epoxy (known as hybrid), straight epoxy (fusion bonded epoxy) and acrylics.

Galvanized Coated tanks is engineered to your site’s specification and installed by a trained crew. Galvanized bolted steel tanks have been the workhorse in the liquid storage industry for many years. These tanks are fabricated with galvanized steel panels bolted together making them economical, easy to transport to project site, easy to erect, and have a long-lasting interior and exterior finish. Tank bolts have high tensile strength and are available in three finishes: hot-dipped galvanized, encapsulated & stainless steel. For resistance to a variety of liquids such as water, wastewater and oils, several liner materials are available including ethylene propylene diene monomer (EPDM), butyl, and poly vinyl chloride (PVC) with or without NSF 61 Potable Certification. Tank nozzle and MaxAccess™ XXL (side manways) gaskets are precision punched to fit exactly and are formulated to remain flexible and not separate from the tank surface. Climate Tanks™ steel bolted tanks meet and exceed a number of industry standards including American Water Works Association (AWWA) D103, National Fire Prevention Association (NFPA 22), FM Approvals, European Union (EN),  and can be used for a variety of applications including potable water, wastewater, fire protection systems, slurry and agricultural, mining, ClimaHarvest™ (rainwater and stormwater harvesting), dry bulk, certain chemicals, processing, cooling tower and blow down, and many more applications.
