【0014】 [0014]

【発明の実施の形態】先ず、本発明のプレコート鋼板に用いる鋼板は特に制限はないが、厚さ0.3〜2.3m DETAILED DESCRIPTION OF THE INVENTION First, steel sheets used for precoated steel sheet of the present invention is not particularly limited, the thickness 0.3~2.3m
mの亜鉛めっき鋼板,亜鉛系合金めっき鋼板,アルミめっき鋼板,クロムめっき鋼板およびステンレス鋼板等を用いることができる。 Galvanized steel sheet m, zinc alloy plated steel sheet, it is possible to use aluminum-plated steel sheets, chromium-plated steel sheet and stainless steel plate or the like.
