Steel Windows and Doors

From narrow sight lines to exceptional thermal performance, we have a product to suit every project

W20 Suite

The single glazed classic

Considered the original in steel joinery, this is the most slender hot rolled window suite available in New Zealand. Introduced to New Zealand circa 1960, the W20 suite stands the test of time. Today it’s used in both residential and commercial projects for architectural and some fire rated applications.

Belgian U suite

Traditional style, double glazed

Still boasting a slim, elegant profile, the Belgian U suite is set slightly wider than W20 to accommodate double glazing. Great for projects that require a traditional aesthetic, with greater thermal efficiency.

Why steel joinery?

With a tried and tested history throughout Europe, steel joinery has proven its durability and character for generations.

As a premium material, it offers performance that’s hard to match with timber or aluminium while also being extraordinarily customisable and durable. If you are looking for an energy efficient, high quality, highly customisable joinery option, then steel is worth your attention.
