LVL Portal Frame Structures in New Zealand |
This is a paper written by Cameron Rodger and Warwick Banks of CHH Woodproducts NZ and discusses the design and development of an LVL based solution for the Fortress Dry Mill. The building has clear internal spans of 33m and portal frames at 10m bays. | More > |
Timber Engineering Design Made More Accessible |
This is a paper written by Bruce Hutchings of Timberbuilt and Hank Bier of CHH Woodproducts NZ and presented to the 1999 Australasian Structural Engineering Conference in Auckland. Please note that this paper is provided for general information only. Changes to standards since it was written mean that some of the capacities provided may be outdated and should not be used for specification. | More > |
LVL products for large span applications
CHH Woodproducts New Zealand has developed new products including 90mm thick hySPAN and Cross Banded LVL to allow designers the ability of built up sections within large span buildings. These products are project specific and have minimum order volumes. To obtain further detail or learn more about these products contact our technical team on 0800 808 131.
Please note that other technical information and span tables for residential applications and commercial floor design can be found under Library.
