Metal roof panel

Metal roof panel refers to a roof form that uses metal sheet as the roof material and combines the structural layer and waterproof layer into one. It usually consists of two parts: metal sheet and coating. There are many types of metal sheet, including single board and composite board. A layer of insulation is added between the two metal sheets, which plays a more prominent role in practical use. The connection methods of metal roof panels mainly include lap connection, bite connection, buckle connection, and locking connection. The following are specific introductions to these connection methods:

1. Overlapping connection

Overlapping connection is a common connection method, in which the longitudinal edges of the formed plate can overlap with each other. After the boards are naturally overlapped, they are connected to the supporting structural components through fasteners. Overlapping is divided into two types: unsupported and supported. unsupported is usually used for low wave plates, while supported is used for high wave plates. The material of the metal roof panel overlap fixing bracket is usually galvanized steel plate, and the connection method is that the bracket is fixed to the purlin with self tapping screws, and the profiled metal plate is fixed to the bracket with self tapping screws.

2. Occlusion connection

Interlocking connection refers to the longitudinal edges of formed plates that can overlap with each other. After overlapping, the plates are rolled and interlocked along the length direction by a special tool, and connected to the supporting structural components through a fixed bracket. There are various forms of bite connections, including 180 degree and 270 degree bite connections, which are suitable for different types of boards and slope requirements.

3. Buckling connection

Buckling connection refers to the longitudinal edges of formed metal roof panels that can overlap with each other, and the panels are pressed together and connected to the supporting structural components through fixed brackets. This connection method is suitable for specific high-strength steel plates.

4. Lock connection

Lock connection refers to the interlocking of formed plates at the overlapping position, and the connection with the supporting structural components after being hooked together with the connecting piece. Suitable for various types of plates, such as steel plates, stainless steel plates, aluminum alloy plates, etc

The above are the main connection methods for metal roof panels, each with its specific application scenarios and technical requirements. In practical applications, choosing the appropriate connection method is crucial for ensuring the waterproof performance and structural stability of the roof.
