Please note; H6 products do not carry a guarantee or warranty. These products are treated in accordance with NZS 3640 and the chemical content as part of this requirement is discussed with each customer. However the exact conditions of use, the environment where the products may be used and any fabrication methods that may be involved, are all unknown and factors that Goldpine has no direct control over, meaning that Goldpine cannot give a guarantee or warranty under those circumstances.
