Hot-dipped pre-galvanized accessories (Z4)

This EPD covers all accessories made from hot-dipped pre galvanized steel. Pre galvanized steel has been subjected to a process covering sheet steel with a thin layer of zinc-aluminium-magnesium alloy, which gives a bright surface. This zinc layer of 25 µm thickness is in accordance with ISO EN 10346, offers protection due to its low electrode potential and slow corrosion rate. Products in pre galvanized steel are suited for installation in environments with high corrosion rate.
