Guaranteed Performance

The fact that we extensively test our connection solutions gives you the reassurance that they will perform in the toughest conditions. Our connector products comply with the AU/NZ timber connector requirements, and our fastener products comply with the European timber fastener requirements. They are suitable for use with AU and NZ sawn timbers, CLT, LVL, and other engineered timber products designed by specific engineering design using AS 1720, NZS AS 1720.1, or NZS 3603, or for prescriptive/conventional connector applications AS 1684 and NZS 3604.

The quality and variety of our product lines gives engineers and builders more freedom to design flexibly, while offering reliable and proven performance. In addition, customers can count on our technical support and a team of experienced field representatives.

The characteristic and design values published within this document have been determined from test and calculation values in accordance with AS 1649, AS 1720, and NZS 3603 for connectors and the fastener characteristic values from BS EN14358 for use with Limit State Design methods. Corresponding deflection limits are published, where appropriate, which indicate the amount of slip in the connection at the design capacity.

Cross-Laminated Timber (CLT)

CLT is growing in popularity as a sustainable and beautiful construction material. Practical too, CLT can be used for walls, floors and ceilings and is well suited to offsite assembly.

CLT has various benefits making it an attractive building material. These benefits include:

• Design flexibility - CLT has many applications. It can be used in walls, roofs or ceilings. The thickness of the panels can easily be increased by adding more layers and the length of the panels can be increased by joining panels together
• Prefabrication - floors or walls made from CLT can be fully manufactured before reaching the construction site, which decreases lead times and could potentially lower overall construction costs

Engineers and Architects are now favouring CLT for its elegance, sustainability and its cosmetic appearance.
