This article describes the maintenance of galvanized steel

This paper introduces the reasons for the uneven wall thickness of seamless steel pipes

Compared with the aluminum-zinc alloy, the galvanized layer has relatively active chemical properties, so the anti-corrosion ability is quite different. The test under the same outdoor conditions shows that the service life of the galvanized sheet is more than four times that of the galvanized sheet......

Galvanized steel refers to galvanizing ordinary carbon construction steel, which can effectively prevent steel from corroding and rusting, thereby prolonging the service life of steel.

galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first.
