Quality / Warranty


The qualiy of all product ranges is VMZINC’s core preoccupation and applies in the first instance to rolled products manufactured at our various production sites.



To ensure traceability and give professionals a guarantee of the superior quality of zinc used, sheets and coils are marked with ink. This marking guarantees compliance with the EN 988, KOMO 7056 and ASTM 69 standards, as well as with the requirements of the PREMIUMZINC label. It guarantees high level manufacturing and control of VMZINC products.

CE marking

VMZINC adopted the European directive on Building Products. The harmonised standards concerning self-supporting (EN 14782) and fully-supported (EN 14783) metal roof and façade products, are used for CE marking.


OHSAS 18001 certification


Auby and Viviez obtained certification for the OHSAS 18001 : 2007 reference system concerning safety.



VMZINC product warranty

All VMZINC rolled products are covered by a 10-year guarantee covering the compliance of our materials with EN 988 European standards, with PREMIUM quality requirements, with ISO 9001 and possible perforations that may be caused by a production defect in the rolled zinc.

This guarantee applies when the products have been used and installed by recognised professionals in compliance with VMZINC technical specifications and industry standards in force in the country where the product is installed, and respecting conditions of use and maintenance.
