What happens when galvanized touches copper?
In Contact with Other Metals | American Galvanizers Association
If an installation requires contact between galvanized materials and copper or brass in a moist or humid environment, rapid corrosion of the zinc may occur. Even runoff water from copper or brass surfaces can contain enough dissolved copper to cause rapid corrosion.
Does galvanized steel need to be painted?
Hot Dip Galvanizing by itself is a long lasting, cost effective means of corrosion protection. However, galvanised steel can be painted for the following reasons: add colour for aesthetic, camouflage, or safety purposes. increase the economic life of a structure.
Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer.
Galvanized coil is produced by advanced and improved Sengimir galvanizing method on the continuous hot-dip galvanizing production line of cold rolling mill, with excellent quality and stable performance
The product has the following characteristics:
(1) Excellent cold-rolled steel strip as the base material, excellent processing performance and good stamping resistance.
(2) The zinc layer has uniform thickness, strong adhesion, no peeling during processing and molding, and good corrosion resistance.
(3) The surface is smooth, the size is accurate, the board surface is straight, and the zinc flower is uniform and beautiful.
(4) After passivation, oil treatment, short-term storage in the warehouse will not deteriorate.
(5) After the surface is smooth, it is a good substrate for making anti-corrosion coated plates
