DX51D Galvanized Steel Coil Cold Rolled Z275 ISO9001 30-200g, 30-275g/m2
The thin steel plate is immersed in the dissolved zinc bath so that its surface adheres to a thin steel plate. It is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the plating groove dissolved with zinc to make galvanized steel plate. This steel plate is also made by hot immersion, but after the groove, it is immediately heated to about 500 ℃, so that it generates an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weld ability.
How do you keep galvanized steel from rusting?
The most important step in preventing corrosion on galvanized steel is keeping it out of environments where it is exposed to substances with a pH below 6 or above 12. One side of this requirement is that it is important to keep galvanized steel out of acid rain.
Should galvanized steel be painted?
The truth is that paint will not adhere to galvanized steel. The layer of zinc left on the metal after the galvanization process is meant to reduce corrosion, but it also rejects paint, eventually causing it to peel or shed.
