Natural titanium zinc with protective coating on the back

NedZink NATUREL Pro-Tec


Product description

NedZink NATUREL Pro-Tec is titanium zinc produced by NedZink according to EN 988 & ASTM B69 with a protective coating on the back side for application on either cold or hot roof constructions.

Small quantities of the alloy elements copper, titanium and aluminium are added to electrolytically refined zinc (with a purity of min. 99,995% Zn, Z1 according to EN 1179) based on EN 988 & ASTM B69. The protective coating on the backside protects the zinc against the effects of water vapour and other substances. The good processing properties of zinc are retained.

The chemical composition, mechanical and physical properties and measurement tolerances of the base material are stipulated on the KOMO product certificate and the product certificate from Lloyd’s Register, LRIQS (Approval QIS 122). The material properties are verified by an independent and neutral research institute on a random basis. The product certification and the ISO 9001 certificate for the quality management system at NedZink assure a constant and uniform high quality, meeting our own standards and far exceeding EN 988. The Pro-Tec protective coating on the back suffices with regard to various quality requirements set in ‘EN 13523’ and ‘EN 4628'.

Transport and storage

NedZink products are packed and sent dry. The advice is to store titanium zinc dry and ventilated. This reduces the probability of condensation formation.


NedZink NATUREL Pro-Tec is assembled with the visible NATUREL side on the outside. Mechanical deformation of zinc below 7°C material temperature is not allowed.
