Square Galvanised


DuraGal® Plus SHS hot dip galvanized square hollow sections that offer the advantage of better protection against the elements over traditional primer painted products. The zinc coating protects the sections and reduces the risk of cracking or fracturing.

DuraGal® Plus SHS is a high-strength cold formed square hollow section that is galvanized to AS/NZS 4792 and has a minimum average coating mass of 100 grams per square metre applied to the exterior of the section.

DuraGal® Plus SHS is available as C450PLUS structural tube, which is the highest strength grade of C450L0, to AS/NZS 1163. C450L0 still has the workability and pliancy of C350L0.
