Over 65 Years of Precast Excellence
Stahlton has been shaping the future of New Zealand construction since the 1960s. Originally established under the name Amalgamated Brick & Pipe Ltd, the company began by supplying prestressed ribs under a Swiss licence—branded Stahlton (from the German words Stahl = steel and Ton = clay).
Throughout the 1980s, Stahlton expanded with precast factories in Balclutha, Dunedin, and later Christchurch, manufacturing both prestressed flooring products and complex structural and architectural precast components under the Stahlton licence.
A Period of Growth
In 2007, Stahlton entered a major growth phase with the acquisition of Pre-Cast Components (PCC) plants in Ōtaki and Hamilton—a respected name in the precast and prestressed concrete sector.
Later that same year, the company further expanded by acquiring five Stresscrete plants in Cromwell, Christchurch, Bulls, New Plymouth, and Tauranga. These strategic acquisitions brought deep technical expertise and a highly experienced team, enabling Stahlton to serve a growing national market.
This period of growth led to the unification of operations under the name Stahlton Engineered Concrete, establishing the brand as a national leader in the design and supply of prestressed and precast concrete solutions.
Reshaping for the Future
Between 2011 and 2013, shifting market conditions prompted Stahlton to consolidate its operations. Plants in Dunedin, Tauranga, and Bulls were closed, while facilities in Balclutha, Cromwell, New Plymouth, and Hamilton were sold.
Today, Stahlton operates from three key locations:
-
Auckland (Main manufacturing hub)
-
Ōtaki (Specialising in Transpower octagonal poles)
-
Christchurch (Supporting South Island distribution)
These locations allow us to deliver products efficiently across New Zealand.
A New Chapter with Nauhria
In 2021, Nauhria Group acquired Stahlton’s prestressed flooring business from Fulton Hogan, retaining the well-known Stahlton name and rebranding the business as Stahlton Prestressed Limited.
As part of this acquisition, manufacturing operations were relocated to a purpose-built, state-of-the-art facility in South Auckland. This move included significant equipment upgrades and allowed Stahlton to deliver even greater quality and consistency to the market.
The acquisition also expanded Nauhria Group’s offering—adding prestressed flooring to their already comprehensive suite of concrete solutions. Fulton Hogan retained ownership of bridge beams and other infrastructure products under its own brand.

With over six decades of experience, Stahlton remains one of New Zealand’s most trusted suppliers of prestressed concrete flooring systems.
