The roof panels and wall panels formed by the color steel roofing press machine have their durability and waterproof performance directly influenced by the fixation methods and connection techniques during the construction process. The common construction points include the following aspects:

1. Fixed method
Through-penetration fixed
Directly penetrate the colored panel through self-tapping screws or rivets and fix it on the purlins or other supporting components.
Common methods: peak-fixed, valley-fixed, or a combination of both.
Features: Simple construction, Widely used.
Hidden fastening concealed fixed
First, fix the hidden fastener on the purlin, then fix it by the center rib of the colored panel fitting with the rib of the hidden fastener.
Features: Neat appearance, Better waterproof performance, Often used in roofing systems.

2. Selection of Fasteners
The type of fastener should be chosen based on the lifespan of the building structure to ensure it matches the lifespan of the exterior covering material.
The thickness of the steel purlins should not exceed the self-drilling capacity of the fastener.
Common forms: fasteners with plastic heads, stainless steel caps, or coated protection.
Except for the special fasteners for concealed fastening, all other fasteners must be equipped with washers to accommodate the installation of the light panels and the wind pressure environment.

3. Connection of colored panels
Lateral connection: During installation, it is necessary to ensure that the edge connections are accurate and tight. Temporary clamps can be used for fixation to ensure the accuracy of the position.
End connection: Generally, the length of the roof panel can meet the requirement of full laying, and usually no end connection is needed. If connection is necessary, it should be ensured that the connection part is compacted and aligned to avoid water leakage.
Fixation sequence: Start from the middle of the panel and extend to both sides gradually to ensure uniform force distribution on the panel surface.

Conclusion
The construction of the color steel roofing press machine is not only an installation process, but also an important link that affects the service life of the building. By reasonably selecting the fixation method, matching screws and controlling the joint accuracy, the sealing performance and durability of the roof and wall systems can be significantly improved.
