MN73屋(wu)面系統采(cai)用360度(du)(du)直立鎖邊技(ji)術，屋(wu)面板先在(zai)工(gong)(gong)(gong)廠(chang)預卷270度(du)(du)，再現場將屋(wu)面板和(he)滑動支座連(lian)接(jie)在(zai)一起，形成(cheng)初步咬合自鎖270度(du)(du)，具(ju)有(you)一定抗風能(neng)力，保證(zheng)施工(gong)(gong)(gong)安全(quan)同時可(ke)(ke)以(yi)最大限(xian)度(du)(du)避免咬合過程中鍍層及烤漆層龜(gui)裂。美耐建筑的(de)直立鎖邊技(ji)術可(ke)(ke)以(yi)確保卷邊的(de)緊實，防(fang)止雨水進入，又不(bu)會(hui)破壞鍍層，并(bing)且在(zai)卷邊內有(you)工(gong)(gong)(gong)廠(chang)預置膠，可(ke)(ke)以(yi)幫助杜(du)絕毛細(xi)滲水，形成(cheng)牢固(gu)的(de)水防(fang)線(xian)。
