Dry hanging exercise
Dry hanging is a common installation method of advertising signs at the door. If the building area is large, the triangular iron keel is generally welded in one piece, and it cannot be hoisted as a whole after welding on the ground. In the welding process, we will ensure the vertical flatness of the facade by hanging lines to ensure the construction quality.
Adhesion process
Sticking technology is another commonly used installation method of door advertising signs. This method is mostly used for the installation of advertising signs at the door. It is a common method to use fire-proof wood plywood as the backing, which can ensure the firmness of advertising signs.
Potential security risks
If the wooden splint is not used as the base, the aluminum-plastic plate can be fixed with double-sided adhesive or structural adhesive. However, this method may not be strong enough. With the passage of time, especially after being subjected to internal and external wind pressure and adhesive aging, aluminum-plastic plates may fall off, which is undoubtedly a safety hazard.
Leave vertical seam
In order to ensure safety and beauty, we suggest leaving more vertical seams and less flat seams during installation. The practice of three sides is usually to extend a small part on the side and leave a gap on the side, which is both beautiful and safe.
