BHP

New Zealand Steel produces a range of coated steel products.

Galvsteel

Traditional galvanised steel is offered under the trade name of GALVSTEEL™. This material has a 100% zinc coating and is available in a range of dimensions, grades, zinc coating weights and types.

Zincalume

ZINCALUME® zinc/aluminium alloy-coated steel has a 45% zinc, 55% aluminium alloy coating which offers superior corrosion resistance compared to galvanised steel in most environments (particularly coastal environments).

Colorsteel

COLORSTEEL® is prepainted steel with an oven-cured paint coating applied to a ZINCALUME® coated steel base. This is produced on a continuous coil to coil operation at the New Zealand Steel Glenbrook works. The pre-painting process gives excellent adhesion to the substrate, allowing rollforming to be performed without delamination or deterioration of the paint film. COLORSTEEL® is produced using either an AZ150 ZINCALUME® coating (150g/m2 zinc/aluminium alloy) for Endura™ or an AZ200 ZINCALUME® coating (200g/m2 zinc/aluminium alloy) for Maxx™.

Colorsteel G2

COLORSTEEL® Endura™ products have an AZ150 ZINCALUME® coating (150 g/m2 zinc/aluminium alloy) on a steel base. Endura™ is available in 24 colours, selected for their ability to provide optimum performance, durability and appeal.

Colorsteel VP

COLORSTEEL® Maxx™ products have an AZ200 ZINCALUME® coating (200g/m2 zinc/aluminium alloy) on a steel base. This product utilises a heavy duty coating and is intended for improved performance in all environmental categories, especially Very Severe environments. Maxx™ is available in 12 colours.

Pacific Coilcoaters

Pacific Coilcoaters produce a range of prepainted steel coil.

ZR8

It is suited to environments such as severe marine, geothermal and industrial sites where there is a high risk of corrosion due to corrosive elements in the atmosphere.

ARX

ColorCote® ARX™ has a tough, durable, organic coating applied in a continuous process to an aluminium substrate.

Designed to provide a high level of structural & aesthetic integrity in very severe environments (ISO Category 5)
