MN73屋面(mian)系統(tong)采用360度(du)(du)(du)直(zhi)(zhi)立(li)鎖(suo)邊(bian)(bian)技(ji)術，屋面(mian)板先(xian)在(zai)工(gong)廠預卷270度(du)(du)(du)，再(zai)現場將屋面(mian)板和滑動支(zhi)座連接在(zai)一(yi)起(qi)，形(xing)成(cheng)初步(bu)咬合自鎖(suo)270度(du)(du)(du)，具有(you)一(yi)定抗風能(neng)力(li)，保證施工(gong)安全(quan)同時(shi)可以最(zui)大限度(du)(du)(du)避免咬合過程中鍍層(ceng)及(ji)烤漆層(ceng)龜裂。美耐建筑的(de)直(zhi)(zhi)立(li)鎖(suo)邊(bian)(bian)技(ji)術可以確保卷邊(bian)(bian)的(de)緊(jin)實，防(fang)止雨水進入，又不會破壞鍍層(ceng)，并且在(zai)卷邊(bian)(bian)內有(you)工(gong)廠預置(zhi)膠，可以幫助杜(du)絕毛(mao)細滲水，形(xing)成(cheng)牢固的(de)水防(fang)線。
