China ap­proves Ra­di­ata for build­ings

New Zealand Logger - - Forest Talk -

RA­DI­ATA PINE IS EX­PECTED TO BE MORE widely used in China fol­low­ing a re­vi­sion to that coun­try’s build­ing de­sign reg­u­la­tions that comes into force in Au­gust.

Cur­rently a sig­nif­i­cant amount of the ex­ported logs from New Zealand ends up as low-grade con­crete form­ing tim­ber, but this move could see it in­creas­ingly used in higher value prod­ucts.

Of­fi­cials in China re­cently an­nounced that Ra­di­ata Pine struc­tural tim­ber is to be in­cluded in Chi­nese Code of De­sign for Tim­ber Struc­tures GB50005 from Au­gust 1 of this year.

The an­nounce­ment sees the in­clu­sion of de­sign prop­er­ties for a num­ber of grades and sizes of NZ Ra­di­ata Pine, in­clud­ing SG6, SG8, SG10, SG12 and SG15 grades and 45x75, 45x90, 45x140, 45x190, 45x240 and 45x290 sizes.

To be able to use the de­sign prop­er­ties stated, the tim­ber must be graded and ver­i­fied ac­cord­ing to NZ rules, such as 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.

The move is the re­sult of ef­forts by the NZ Wood Pro­ces­sors & Man­u­fac­tur­ers As­so­ci­a­tion work­ing with SCION to en­sure NZ Ra­di­ata Pine grades were in­cluded in the re­vi­sion, along with ex­ten­sive as­sis­tance from Min­istry for Pri­mary In­dus­tries and In­du­for Group.

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