    Building warranties depend on correct installation and site conditions

    WCTNZ® building systems may involve site-specific foundation, fixing, anchoring, assembly, access, weather exposure, public-use, structural, and maintenance considerations.

    Warranty cover may be affected if the building system is installed, altered, moved, fixed, maintained, or used outside the supplied instructions, project documentation, engineering information, or agreed conditions.

    Where a project involves public use, commercial use, remote sites, wind exposure, corrosion risk, coastal conditions, or harsh environmental conditions, customers should ensure the selected building system, installation method, and maintenance pathway are suitable for the site.

    Replacement parts

    Replacement parts and parts availability

    WCTNZ® is to furnish new parts to a customer whose product fails within the allotted warranty period for the particular component, provided that inspection shows that such failure is due to defective material or workmanship.

    Any part supplied is warranted for the balance of the original warranty period based on the respective manufacturer’s warranty

    All support information for warranty claims is to be supplied by the customer to WCTNZ® within 21 days of alerting WCTNZ® to the fault

    The warranty period for a part begins from the date the original product was dispatched, plus 5 additional days for transportation

    All faulty parts are to be returned to WCTNZ®; shipping of these is the customer’s responsibility unless otherwise agreed

    If a warranty replacement part is sent out and the original part is proven not to be faulty, the customer will be charged for the replacement part

    WCTNZ® endeavours to hold replacement parts in stock to the best of our ability. If replacement parts are not available at the time of a warranty claim, the customer is responsible for covering all logistics costs from the point of origin
