Statement of Building Code Compliance

Simpson Strong-Tie extensively test their connection solutions for reassurance that they will perform in the toughest conditions. Connector products comply with the AU/NZ timber connector requirements, and 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 these product lines gives engineers and builders more freedom to design flexibly, while offering reliable and proven performance. In addition, customers can count on 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.
