Duragalv Hot Dip Galvanising
The new range of Duragalv® coating options - 70, 100 and 140 allows selection of an appropriate Superlintel and protection system to meet the different categories of atmospheric corrosivity across the UK.
These 5 categories are defined on the Galvanizer’s association Zinc Millennium Map of atmospheric corrosivity. The Millennium Map incorporates data issued by MAFF (ministry of Agriculture, Fisheries and Food), another source for evaluating climatic/atmospheric agents cited in BS 7543:2003, section A.6.3.
Units are manufactured from structural steel plate and are hot dip galvanised, in house, after manufacture to Dura Galv 70 finish to BS EN ISO 1461:1999 as standard.
Dura Galv 100 a superior galvanising finish tested in accordance with BS EN ISO 1461:1999 but with an increased thickness of 100 (minimum) micron zinc coating thickness, for longevity in harsh and aggressive environments.
Dura Galv 140 a superior galvanising finish tested in accordance with BS EN ISO 1461:1999 but with an increased thickness of 140 (minimum) micron zinc coating thickness, for longevity in harsh and coastal environments.
The Duragalv® process is more flexible and sophiscated than the previous Ultra-Galv™ 2000. Ultra-Galv™2000 achieved a maximum 2000 gsm coating on lintels, but wthout the progressive coating thicknesses now available with the Duragalv® family only possible by the contolled inhouse galvanising processes.
More Economical In-house Galvanising
Duragalv® now enables the specifier to determine the thickness required for all areas in the UK - therefore specifying more controllable and a more economical range of coatings.
The Duragalv® new generation of post-galvanising is backed by distinctive product labels, showing tested and guaranteed coating thickness to comply with the galvanizing standard BS EN ISO 1461: 1999.
Specifier Orientated Company
Jones of Oswestry continues to be a specifier orientated company working closely with engineers and architects to solve their lintel applications. We provide a full range of technical support, ranging from bespoke design to structural calculations and lintel scheduling.
These have been some of our major services to the specifier over the past 30 years.
