The optimized protection for a new generation of coated steels
- ZM Evolution® is the new galvanised steel from Arcelormittal Construction. It has been developped especially for the construction market. ZM Evolution is used for the whole range of product even as bare or as pre-painted steel
- ZM Evolution® is made according a standard hot dip galvanisation process . The steel is dipped into a bath whom composition includes zinc, aluminium and magnesium
- The zinc gives the cathodic protection which is active and traditional, while aluminium brings a passive layer that protects zinc and slows down the sacrificial reaction. Magnesium allows to stabilise the system and offers to the coating a resistance against corrosion at least 3times higher than standard hot dip galvanised
ZM Evolution® shows a grey, homogenous aspect without spangle
With time, there is a nice grey patina that appears
Brasing with thin-lead process is not compatible with this substrat. We suggest to use sealant for all the water tightness works.
