Hot Rolled Black Seamless Carbon Steel Tube Galvanized For Warehouse
Product Description:
Galvanized paint is also available to help further protect your project. It is especially useful to protect weld lines on galvanized projects as these lines are at risk to rust.
Hot-dipped galvanized steel is dipped into a vat of molten zinc which coats the steel. The galvanized steel is removed and allowed to cool. Structural shapes such as angles, channels are frequently hot-dipped.
Electro-galvanized steel, as its name indicates is a plating process where the steel is placed in an electrically charged solution of zinc and saline. This causes the zinc to chemically bond to the conductive steel. Electro-plating is frequently used for coiled sheet steel which is later formed into shapes such as c-purloins, corrugated sheets, or can be formed and welded into pipes and tubes. Often a UV-resistant polymer is applied after electro-plating to further protect the steel and provide a paintable surface that does not need to be primed.
Galvanized steel is an ideal choice for those trying to balance cost and longevity in outdoor projects however the effectiveness of galvanized steel is severely limited in marine environments. In harsh environments, the zinc oxidizes quickly into "white rust" which washes away leaving the steel exposed. Painting your galvanized projects is an easy way to provide an extra layer of protection.
