Overview of Perforated Metal Panel Installation
Perforated metal panels are prized for their breathability, strength, and visual appeal, making them ideal for façades, partitions, and ceilings. Choosing the right fixing methods not only guarantees structural stability but also preserves the panel’s corrosion-resistant finish. The two most common approaches are screw (or bolt) fixing and welding fixing, each with distinct advantages. Selecting the appropriate method depends on project requirements and environmental conditions.
 
I. Screw Fixing Methods
1. Direct Screw Installation
Procedure: Use self-tapping screws to fasten the panel directly into the substrate (e.g., wood or metal framing).
 
Advantages: Quick and easy installation without pre-drilling.
 
Tip: Verify that the substrate thickness can withstand the screw torque to prevent panel distortion.
 
2. Pre-drilled Hole Alignment
Procedure: If the panel edge already has factory-punched holes, align these with the framing and secure using standard screws or rivets.
 
Advantages: Protects the factory finish and extends corrosion resistance.
 
Best for: Outdoor or high-humidity environments where coating integrity is paramount.

II. Welding Fixing Methods
1. Spot Welding for Positioning
Procedure: Place the panel in its final position, then use spot welds to attach it to the supporting structure.
 
Advantages: High connection strength—ideal for load-bearing or high-stress applications.
 
Drawback: Heat from welding can damage the surrounding protective coating, risking localized corrosion.

2. Post-Weld Protection
After welding, promptly apply touch-up paint or corrosion-resistant coating to weld seams and adjacent areas.
 
In corrosive environments such as coastal or chemical facilities, consider extra-thick coatings or specialized sealants for added protection.
 
Pro Tips
Choose Based on Priorities: For maximum corrosion resistance and surface finish, prioritize screw fixing; for integrated strength and load capacity, welding is preferred.
 
Pre-Punch Holes: Request factory-punched mounting holes aligned with your site’s framing to minimize on-site drilling and protect the finish.
 
Final Inspection: Regardless of fixing method, conduct a full-panel inspection of the protective coating after installation and repair any damaged spots immediately.
 
By selecting the right fixing method and ensuring thorough post-installation protection, you’ll maintain both the beauty and structural integrity of your perforated metal panels for years to come.
