OneSteel produces a range of structural Rectangular Hollow Sections (RHS) with
an In-line Hot-dip galvanized coating on the external surface and painted internally.
The galvanized coating is applied over a prepared metal surface, to produce
a fully bonded external coating with a minimum average coating mass of 125g/m2,
in accordance with AS/NZS 4792:1999.
The zinc surface then has a surface conversion coating applied to improve adhesion
of paint and powder coating.
