Radiata pine added to Chinese Design Code

Friday 2 Feb 2018

 
The revision of the Chinese Code of Design for Timber Structures GB50005 is to be published on 1 August 2018. Of interest to producers of radiata pine structural timber will be the inclusion of design properties for grades and sizes of NZ radiata pine.

The grades included are SG6, SG8, SG10, SG12 and SG15. Sizes included are 45x75, 45x90, 45x140, 45x190, 45x240 and 45x290. To be able to use the design properties stated, the timber must be graded and verified according to NZ rules, i.e. verification must be done to NZS 3622, with third party auditing.

This means that for the first time, engineers in China will be able to design buildings using the NZ grades and sizes. WPMA cooperated with SCION in getting these NZ radiata pine grades included in the revision; and received extensive assistance from Ministry for Primary Industries and Indufor Ltd.

Work is now being done to develop the handbook for GB 50005, coordinated by WPMA and SCION; meetings are attended by Dr Minghao Li from University of Canterbury and Bill Lu of Indufor. Assistance is again being provided by MPI and also by the Ministry of Foreign Affairs and Trade.
