What specifications of expansion screws are used to install billboards?

The method of fixing the brand depends on the material, weight, usage scenario and required firmness of the brand.

For lighter signs, such as interior decoration signs or small billboards, double-sided tape or strong glue can be used to fix them. This method is quick and easy, requires no special tools, and is suitable for temporary or lightweight applications. When using it, just clean the adhesive surface to make sure it is free of dust and grease, then stick double-sided tape or strong glue on the back of the brand, and finally pre ss it where it needs to be fixed. It should be noted that the stickiness of double-sided tape or super glue will gradually weaken over time, so it may not be suitable for long-term fixing situations.

For heavier signs or occasions that need to withstand greater external forces, such as outdoor billboards or industrial signboards, a stronger fixation method is required. A common method is to use screws and expansion screws to secure the sign to the wall or bracket. First, you need to drill holes at the fixed location, then insert the expansion screw into the hole and tighten it with a screwdriver so that the expansion screw expands and is firmly fixed in the hole. Then, place the sign in the pre determined position and use screws to pass through the reserved holes on the sign and tighten the expansion screws. This method has a stable structure and can withstand large external forces and wind and rain erosion.

In addition, for some special-shaped signs or occasions that require quick installation, suction cups or magnets can also be used for fixing. The suction cup fixation method is suitable for surfaces that are smooth and not easy to fall off, such as glass, ceramic tiles, etc. The magnet fixing method is suitable for metal surfaces, and the brand is firmly fixed in the desired position through the adsorption force of the magnet. It should be noted that when choosing a magnet fixation method, make sure that the magnet's adsorption force is strong enough to avoid safety hazards caused by the brand falling off.

In short, there are various methods for fixing brands, and the specific method chosen depends on the material, weight, usage scenario of the brand, and the required degree of firmness. In actual operation, the most appropriate fixing method should be flexibly selected according to the specific situation.
