Magnetic galvanized steel is right, because galvanized steel is magnetic.
Is Galvanized Steel Magnetic?
Yes,
galvanized steel is generally magnetic, but only if the steel substrate is magnetic. Galvanised steel is made when steel is fortified with a powerful layer of zinc. The metal is dipped in an extremely hot bath of molten zinc, which causes a chemical reaction, resulting in a protective layer of zinc which makes the finished product supremely tough. Whilst the zinc that’s added to steel in the galvanisation process is not magnetic, the steel itself is. The amount of zinc used is so little that it doesn’t affect the performance of the steel, meaning magnets will stick to it.
Is Hot-Dipped Galvanized Steel Magnetic?
Yes, hot-dipped galvanized steel is magnetic. The zinc coating of the hot-dipped galvanizing process does not interfere with the magnetic strength of the steel substrate.
How Does Galvanized Steel's Magnetism Compare With That of Stainless Steel?
Galvanized steel is generally magnetic because the steel substrate itself is magnetic. Stainless steel may or may not be magnetic, and can become more magnetic after it has been worked into some kind of useful form. The principle is:
Martensitic stainless steels are magnetic.
Austenitic stainless steels are not.
