According to EN 13523-0, a prepainted metal is a ‘''metal on which a coating material (e.g. paint, film…) has been applied by coil coating''’. When applied onto the metallic substrate, the coating material (in liquid, in paste or powder form) forms a film possessing protective, decorative and/or other specific properties. In 40 years, the European prepainted metal production has multiplied by 18.〔The European market for prepainted metal, ECCA Academy, http://www.prepaintedmetalacademy.eu/prg/selfware.pl?id_sitemap=197&language=EN〕 == Metal == The choice of metallic substrate〔British Standards Institution, BS EN 10169:2010, http://shop.bsigroup.com/ProductDetail/?pid=000000000030251498〕 is determined by the dimensional, mechanical and corrosion resistance properties required of the coated product in use. The most common metallic substrates that are organically coated are: * Hot dip galvanised steel (HDG) which consists of a cold reduced steel substrate onto which a layer of zinc is coated via a hot dip process to impart enhanced corrosion properties onto the base steel. * Other zinc-based alloys are coated onto steel and used as a substrate for coil coating, giving different properties. They give improved corrosion resistance in particular conditions. * Electro-galvanised (EG)〔Wikipedia "Electrogalvanization", http://en.wikipedia.org/wiki/Electrogalvanization〕 coated steel consists of a cold reduced substrate onto which a layer of zinc is coated by an electrolytic process. * Cold reduced steel (CR) without any zinc coating * Wrought aluminium alloys * Many other substrates are organically coated: zinc/iron, stainless steel, tinplate, brass, zinc and copper. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「prepainted metal」の詳細全文を読む スポンサード リンク
