MN73屋(wu)面(mian)(mian)系統采用360度(du)直(zhi)立(li)鎖邊(bian)技術，屋(wu)面(mian)(mian)板(ban)(ban)先(xian)在(zai)工(gong)(gong)(gong)廠(chang)預卷270度(du)，再(zai)現場將屋(wu)面(mian)(mian)板(ban)(ban)和滑動支座連接在(zai)一起，形(xing)成初(chu)步咬合自鎖270度(du)，具有一定抗風能(neng)力，保證施工(gong)(gong)(gong)安全(quan)同(tong)時(shi)可以(yi)最(zui)大限度(du)避免咬合過程中鍍(du)(du)層(ceng)及烤(kao)漆層(ceng)龜裂。美耐建筑的(de)直(zhi)立(li)鎖邊(bian)技術可以(yi)確保卷邊(bian)的(de)緊實，防止雨(yu)水進入，又(you)不會破壞鍍(du)(du)層(ceng)，并且在(zai)卷邊(bian)內有工(gong)(gong)(gong)廠(chang)預置膠，可以(yi)幫助杜絕毛細滲(shen)水，形(xing)成牢固(gu)的(de)水防線。
