BLACK PLATED BUILDING MEMBER AND BLACK PLATED STEEL SHEET FOR BUILDING MEMBER
PROBLEM TO BE SOLVED: To provide a black plated building member and black plated steel sheet for a building member with high corrosion resistance capable of obtaining black appearance without coating and having excellent sustainability of black appearance after processing.SOLUTION: There is provided a building member using a plated steel sheet as a raw material having a black plated layer which: is formed on the surface of a base steel member; has a molten Al/Mg-containing galvanized layer which contains 0.1 to 22.0 mass% of Al and 0.1 to 10.0 mass% of Mg and in which a black oxide of Zn is distributed in a plating layer; and exhibits black appearance in which the surface of the molten Al/Mg-containing galvanized layer has lightness L* value of 60 or less. There is provided a method in which the blackening is performed by bringing into contact with steam at 50 to 350°C under a low oxygen concentration. There is provided a building member which may be a member used for a building such as a house, a building and a condominium irrespective of shape and irrespective of outdoors or indoors, for example, a solar frame, an entrance frame, a ceiling material, a ceiling interior material, a wood deck, a joist, an interior material, a metal material for an inclined roof, a siding fastener, a building hardware and a hinge.SELECTED DRAWING: None
【課題】塗装せずに黒色外観が得られ、加工後の黒色外観の保持性に優れる高耐食性の黒色めっきが施された建築部材、及び建築部材用黒色めっき鋼板の提供。【解決手段】基材鋼材の表面に、Ａｌ：０．１〜２２．０質量％、Ｍｇ：０．１〜１０．０質量％を含み、かつＺｎの黒色酸化物がめっき層中に分布している溶融Ａｌ、Ｍｇ含有Ｚｎめっき層を有し、前記溶融Ａｌ、Ｍｇ含有Ｚｎめっき層の表面の明度はＬ＊値で６０以下である黒色外観を呈する黒色めっき層が形成されているめっき鋼板を素材とした建築部材。黒色化は低酸素濃度下、５０〜３５０℃で水蒸気に接触させる方法。形状を問わず、また、屋外、屋内を問わず、住宅やビル、マンション等の建築物に用いられる部材であればよく、例えば、太陽光架台、エントランス枠、天井材、天井内部材、ウッドデッキ、根太、内装材、傾斜屋根用金物、サイディング留め金具、建築用金物、ヒンジ、等である建築部材。【選択図】なし
