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.
