The building industry, particularly over the last decade, has passed more and more responsibility with performance specifications, tight lead times and fast track construction programmes onto the metal window industry.

This has given us a competitive advantage within the industry.

We are proud to be 100% New Zealand owned and operated. For over 46 years we have turned concepts into buildings of excellence that stand the test of time and enrich our cities.

We continue to pursue innovation and expertise to be a single provider of value and durable world class building envelope solutions; to build stunning buildings across New Zealand and abroad.
