When working with metal deck installation, it’s important to be aware that there are varying methods for connecting the side-laps. The name of the panel typically indicates the type of side-lap connection used, although this isn’t always the case.
Metal deck panels are available in different profiles, some of which have a single side-lap, while others offer multiple side-lap options. When a panel features more than one side-lap, it’s given a specific name to differentiate it and ensure the correct side-lap connection is used during installation.
Interlocking Side-Lap Joints
The interlocking side-lap joint, also referred to as an interlocking seam, is a method of connecting adjacent steel deck panels during installation. This is achieved by utilizing male and female side edges on the panels, which interlock with one another. Typically, the side-laps or interlocking seams are raised above the supports and fastened together using button punches, screws, or welds.
The importance of interlocking side-lap joints lies in the fact that they contribute to the overall strength of the structure and prevent concrete or water from penetrating through the metal deck. By fastening the steel deck panels together, a more robust and secure structure is created.
