30 2. NRAL PRODUCT RAN STANDARDS DSIN LOADIN DURABILITY This catalogue details the Stainless Steel range of BOWMAC products. Refer to separate brochure for the ot Dip alvanised range of BOWMAC products. Applicable timber standards are NZS 3603 and NZS 3604:2011 Section 4 Durability. These can be derived from the allowable bolt loads in timber, using the relevant design code NZS Due to the variations in end use and in particular the environments in which these products could be used, we are unable to provide a specific durability statement. In BRANZ opinion BDO 96/10 however, 304 Stainless Steel is not adversely affected by tanalith treatment and performs considerably better than ot Dip alvanised Steel. In situations where the product could collect wind blown salt deposit not regularly rain washed away, the appearance of the product may be affected. It is not recommended that Stainless Steel fixings be painted over as this may cause a tea staining effect. CUSTOM PRODUCTS BOWMAC also manufactures custom made products to suit specific requirements, using ot Dip alvanised Steel and 304 Stainless Steel.
