    • Metal roofing panels have a forward edge portion with a downwardly extending skirt and return flange and a rear edge or headlap portion with an upwardly open channel and a locking tab extending over a portion of the upwardly open channel. A method of installing the roofing panels includes nailing a lower course of panels in end-to-end overlapping relationship to a roof deck. The forward edge portions of panels in the next higher course of panels are then pressed downwardly into the upwardly open channels of the lower course panels. The return flanges of the upper course panels snap beneath the locking tabs of the upwardly open channels thus locking the panels together and forming a watertight connection between courses of panels.
    • 金属屋顶板具有前缘部分,其具有向下延伸的裙部和返回凸缘以及具有向上开口的通道的后边缘或头部部分以及在向上开口的通道的一部分上延伸的锁定突出部。 一种安装屋顶板的方法包括以与屋顶板的端对端重叠关系钉住下层板。 然后将下一较高层面板中的板的前边缘部分向下压入下层板的向上开放的通道中。 上层板的返回凸缘卡在向上打开的通道的锁定突出部下方,从而将板锁定在一起并且在板的路线之间形成水密连接。
