Description

【発明の詳細な説明】 本発明は一般の圧延鋼材に、溶融亜鉛鍍金を数

錆、防蝕効果を高めようとする目的である。DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to increase the thickness of the plating film by repeating hot-dip galvanizing several times on a general rolled steel material, thereby increasing the rust-preventing and corrosion-preventing effects of the steel.

A thin wire 1 is wrapped around the surface of the second hot-dip galvanized B and immersed in a molten zinc bath to generate a third hot-dip galvanized C. Next hot dip galvanizing A
The structure is characterized in that hot-dip galvanizing is repeated one to several times.

一般の圧延鋼材は、溶融亜鉛浴中の浸漬時間を

1000g／m2以上にならないので、強力な耐蝕性を
期待できないが、本発明では、細い針金１を鍍金

と共に、鍍金の密着力が良好で、衝撃による剥離
を軽減することができる。 For general rolled steel materials, the immersion time in a molten zinc bath is
Even if it is extended to about 10 minutes, the amount of molten zinc deposited remains
Since it does not exceed 1000g/ m2 , strong corrosion resistance cannot be expected, but in the present invention, since the thin wire 1 is interposed between the platings, the plating film layer is increased and the adhesion of the plating is good. This can reduce peeling due to impact.

このように本発明によるときは、極めて簡単に

られる有益な発明である。 As described above, the present invention is an advantageous invention in which plated film layers can be laminated extremely easily and a robust plated steel material can be obtained at a low cost.
