DuraGalUltra Profiles combine the dimensional accuracy and high tensile strength of the cold-forming process with the latest generation of steel production by Austube Mills to produce a product with more than adequate structural ductility for general structural applications. The patented DuraGalUltra process combines cold-forming technology with a corrosion protection process that can be used either stand alone, or in conjunction with top coat systems to cover the majority of corrosion environments included in AS/NZS 2312:2002 'Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings'. The Design Capacity Tables have been prepared for DuraGalUltra angles, channels and flats in accordance with AS/ NZS 4600:2005 Cold-formed steel structures.
Originally printed July 1997, this February 2015 edition includes: October 1998 amendments to Section 8 - web bearing capacity, adopted from the research carried out by The University of Sydney. December 1999 amendments - changes in mechanical properties for angles, t ≤ 2.5 mm. February 2015 - the tables have been updated to reflect changes in AS/NZS 4600 introduced in 2005.
