In this video we will show you what is important in the K2 Base planning when choosing the fastening clip for roofs with flashings made of sheet metal or metal roofing systems. The first step is to determine which type of roofing you are using in the Roof tab. The possible rail systems and suitable clamps are then displayed under Results. Depending on the type of seam (standing seam, double standing seam or angled seam) or metal roof system (Kalzip, Rib-Roof, Domitec or KlipLok), Base automatically offers a suitable selection.
