Over 40 years’ experience goes into every profile


From its locally-based design and manufacturing hub in Avondale, Auckland, the Dynex team creates a broad range of innovative products widely used throughout the construction industry across New Zealand, Australia and the South Pacific.

A lot has changed since 1977 when Dynex first began as a supplier to the glazing industry with a single extruder — but some key principles have remained the same.

Built on a culture of serving New Zealand industry, with a “can-do” attitude towards providing innovative solutions and an unrelenting commitment to quality, Dynex has developed to become a truly world-class operation, and one of the largest extruded plastic profile manufacturers in New Zealand.

Today Dynex is part of Aliaxis, a global leader in water and energy solutions, employing more than 14,000 people and serving customers across 40 countries.

New Zealand brands include Marley, Dux and RX Plastics, all market leaders in their own right.

With access to global innovation and a focus on the needs of local customers, Dynex brings best in class solutions to the NZ market.

As a vertically integrated business, Dynex has the ability to control quality at each aspect of production — starting with in-house PVC compounding which has a capacity to process in excess of 50,000 tonnes per annum, through to extrusion, and distribution.

With dedicated distribution centres in Auckland and Christchurch, customers have confidence that Dynex can deliver quickly nationwide.

Dynex is proud to maintain ISO9001 quality and ISO14001 environmental management certification.

With a long history of developing high-quality seals, and custom solutions for the glazing industry, Dynex is proud to support the Window & Glass Association New Zealand (WGANZ).

Dynex senior product manager Nick Mantell is an industry member on the WGANZ Components Committee.

“It’s been a privilege to play a role within the Window & Glass Association over the past 10 years,” Mantell says.

“There is a high level of professionalism and shared vision to improve the built environment within New Zealand.”

With expertise in rigid, flexible and co-extruded profiles, Dynex understands the intricacies of designing componentry for joinery systems.

Although largely unseen, it is reassuring to know that 40-plus years of experience is contained within each Dynex component.

Such experience is a key reason leading window and door manufacturers choose to partner with Dynex.

Over the years, Dynex has expanded its offering to the building industry, bringing an innovative range of products to market, including DynaFlash, Cavity Closers, PALLISIDE® weatherboard system and Soffit.

With an ongoing commitment to providing expertise, design assistance, new technologies and a culture of helpful support, Dynex continues to strive to serve and enhance the wider construction industry.
