Timber Portal Frame Prefabricators

Below is a list of companies that have had experience in the fabrication of LVL kit set buildings. As well as having fabrication experience the prefabricators have access to material cut to 100 mm increments and a monthly scheduled production period to enable supply of building systems on time and within budget. Each can be contacted for information on pricing and scheduling of individual projects.

At Carters everything we do is aimed at making the building easier for you Carters – Your Building Partner.

Ecospan Buildings

Ecospan Buildings is the commercial arm of Customkit and its expertise lies in the design, fabrication and manufacture of large span LVL timber portal and beam systems to accomodate the New Zealand and export markets as well as the manufacture of specialist box beam and other beam componentry.

Ecospan is a licensed Fabricator with STIC (Structural Timber Innovation Company). We are able to assist in the structural design of your commercial building or we can simply price and supply materials and components.

McIntosh Timber Laminates

McIntosh Timber Laminates are committed to providing prefabricated timber solutions. They have extensive experience in fabricating and delivering kit set LVL packages for portal frames, box beams and other composite LVL systems throughout New Zealand and beyond. With 50 years experience in gluing large section timber components they offer a reliable quality service.

Stanley Group

Stanley Group have a reputation for taking on the tough construction contracts – high value contracts with critical hygiene challenges, those in remote locations or sensitive alpine environments, corporate fitouts with challenging timeframes, contracts with client-occupied spaces or in safety-sensitive trading environments. Typically, these contracts require meticulous planning and exceptional site management. The Stanley companies use innovative construction techniques – such as modular construction – to overcome specific challenges in specific markets and locations.

Timberbuilt Pty Ltd

Timberbuilt is a family owned professionally based timber engineering company specialising in the structural design and use of laminated veneer lumber (LVL).

Timber Imagineering

Timber Imagineering supply fabricated building components utlising LVL, timber and panel products. Timber Imagineering is recognised for its ability to assess, determine and meet their client's needs. In order to provide our clients with the most economical building systems Timber Imagineering offers an integrated engineering service. This includes foundations, steel, concrete and masonry to compliment the timber components, this enables and ensures that the design intent flows through all aspects of the structure.

Providing timber building systems requires careful assessment of the architectural intent in order to determine the most appropriate system. Our in-house detailing and fabrication of timber components will allow for consistent precise systems that will eliminate delays.
