They have a minimum average coating mass of 100 grams per square metre applied to the interior and exterior of the sections.
DuraGal Clear sections are also prepared with a non-chromate passivation treatment which, when combined with appropriate pre-treatments, passes the permeability test specified in AS 4506:2005.
All DuraGal Clear sections are available as C450PLUS structural tube. C450PLUS structural tube achieves the highest strength grade, C450L0, of AS/NZS 1163:2009, whilst maintaining the elongation and formability of C350L0, providing no loss of ductility or workability.
