The waterproof tiles with upright locking seams do not need welding. How do they achieve waterproofing?

The waterproof tiles with standing seam do not need welding, and waterproofing is mainly achieved in the following ways:

1. Mechanical lock edge design: The standing seam waterproof tiles adopt a mechanical lock edge structure. The tiles are locked by precise bite to form a seamless connection. This lock edge design not only fits tightly, but also effectively prevents rainwater from seeping in, relying on the mechanical connection on the structure to achieve waterproofing.

2. High standing edge design: The bite part of the standing seam system is usually higher than the ordinary lock edge, usually ranging from 25mm to 65mm. This high standing edge design can effectively block rainwater and snow, and prevent moisture from penetrating through the bite gap.

3. Hidden fixing: The standing seam tiles are fixed to the roof foundation through hidden fasteners or bracket systems. This fixing method hides the screws or fixings inside the tiles, avoiding the exposed holes from becoming a path for water leakage.

4. Double or multiple lock edges: Some standing seam systems use double or multiple lock edge designs, which increase the firmness of waterproofing through multi-layer bite, further improve the sealing and reduce the risk of leakage.

5. Drainage design: The design of standing seam tiles usually has a specific drainage function to ensure that rainwater can be discharged smoothly along the board surface. Some systems will also add drainage grooves or grooves to improve the drainage capacity of rainwater and prevent water accumulation.

6. Auxiliary waterproof materials: During the installation process, some standing seam systems will use auxiliary waterproof materials such as sealing strips, sealing pads or waterproof tapes at the bite or key nodes to further enhance the waterproof performance.

Through the above waterproof mechanisms, standing seam bite tiles can achieve waterproof performance without relying on welding, which is especially suitable for industrial and commercial buildings with high requirements for roof waterproofing.
