Perforated metal is typically installed using either screw installation or welding installation methods. Choosing the appropriate installation method can ensure the perforated metal is securely fixed while maintaining its surface corrosion resistance.
1. Screw Installation
Screw installation is a common and simple method for installing perforated metal, typically done in two ways:
Direct Installation with Self-Tapping Screws: Self-tapping screws are used to directly fix the perforated metal to the surface. This method is fast but requires ensuring the surface material can withstand the pressure from the screws.
Pre-Drilled Hole Installation: If the edges of the perforated metal have pre-drilled holes, screws can be used to secure it. This method helps prevent damage to the surface anti-corrosion coating of the perforated metal, thereby improving its durability.
The advantage of screw installation is that it effectively avoids damaging the anti-corrosion layer on the surface of the perforated metal, maintaining its corrosion resistance, especially in environments where long-term use is required.
2. Welding Installation
Welding installation is typically used in construction projects that require post-painting treatment, especially in situations where structural strength is important. Perforated metal is fixed in place by spot welding. The steps are as follows:
Position the Perforated Metal: First, place the perforated metal in the designated position and ensure it aligns properly with the surface.
Spot Welding: Use spot welding to secure the perforated metal in place. Spot welding ensures that the metal sheets are firmly attached to the surface, suitable for applications that require higher structural strength or where greater load-bearing capacity is needed.
However, for perforated metal that has already been treated with anti-corrosion coatings, additional corrosion protection is needed after welding. This is because the localized heat from welding may damage the coating, causing corrosion at the welding points. Therefore, it is recommended to apply additional anti-corrosion treatment to the welded areas after the welding process to prevent corrosion.
Tips:
Choose the Right Installation Method: If your project requires higher corrosion resistance, screw installation may be the better choice. For stronger structural connections, welding installation is preferable.
Post-Welding Corrosion Protection: When using welding installation, be sure to address the corrosion protection of the welded points, especially in coastal or humid environments, as the protection is crucial.
Pre-Drilled Perforated Metal: When using perforated metal sheets with pre-drilled holes, make sure the holes align with the mounting surface to ensure secure installation.
