Overview of Main Installation Methods
As a crucial material in modern architectural decoration, the selection of installation methods for perforated aluminum panels directly determines project quality and maintenance costs. The industry predominantly employs three installation approaches:
1.Welding Installation
Ideal for large public buildings requiring high structural strength
Enables rapid construction (3 days/100㎡) but mandates post-weld anti-corrosion recoating
2.Screw Fixation
Preferred for commercial renovations due to adjustable fastening
Features 0.5-1.2N·m torque control and EPDM gasket integration
3.Bent Clip Installation
Non-destructive method suits interior decoration
Requires CNC bending precision (±0.1° angle tolerance)
Welding Technical Specifications
Optimized Workflow
1.Substrate preparation: Sandblast to SA 2.5 cleanliness
2.Tack welding: TIG welding at 250-300mm intervals
3.Full welding: Pulsed MIG welding with 8-10kJ/cm heat input
Quality Control
Electrode: ER5356 for 6061-T6 alloy compatibility
Interpass temp: <120°C monitored by infrared thermometer
Coating repair: 85% Zn-rich spray achieving 120μm DFT
Screw Fastening Protocols
Pre-Drilled Installation
Hole pattern: 500mm (longitudinal) × 350mm (transverse)
Fastening: M6 stainless screws at 1.5N·m with torque wrench
Sealing: Neutral silicone sealant (3mm min. bead width)
Self-Tapping Direct Installation
Screw type: ST4.2 for 1.2-2.0mm sheets
Drilling: 600-800 RPM with carbide step drill bits
Verification: 180N minimum pull-out resistance
Bent Clip Installation Process
Precision Bending Parameters
Die opening: 8× material thickness
Pressure: 10 tons/mm thickness
Dwell time: 3 seconds minimum
Field Installation
Alignment: Laser projection within 1mm/10m tolerance
Clip spacing: 400-450mm with 5mm thermal expansion gap
Noise prevention: MoS₂-impregnated nylon inserts
Quality Inspection Criteria
1.Flatness: ≤1.5mm deviation under 2m straightedge
2.Seam consistency: ≤0.3mm width variation
3.Corrosion resistance: Pass 1000hr ASTM B117 salt spray
4.Seismic performance: ≤15mm displacement in EN 1998-1 testing
