Aluminum single panels use high-quality aluminum alloy sheets as the base material, with advanced CNC bending technology ensuring the panels remain flat and non-deformable after processing and deliver superior anti-external force performance during installation. The surface coating adopts fluorocarbon spray paint, guaranteeing uniform surface color, UV radiation resistance, oxidation resistance and ultra-strong corrosion resistance.

1. Overview of Aluminum Single Panel Curtain Walls

1.1 Specifications

• Common thicknesses: 1.5mm, 2.0mm, 2.5mm, 3.0mm (costs increase for panels thinner or thicker than this range)
• Curtain wall-specific thicknesses: 2.0mm, 2.5mm, 3.0mm (4.0mm and 5.0mm panels are also available on the market)
  

1.2 Classification

1.2.1 By Face Sheet Material

• Aluminum composite panels, single aluminum panels, aluminum honeycomb panels (balancing strength and aesthetics)
• Titanium-zinc plastic-aluminum composite panels, stainless steel panels, color-coated steel plates (with unique performance advantages)
• Fireproof panels, sandwich insulation aluminum panels (with outstanding functional properties)
• Enamel steel plates (with special manufacturing processes)
  

• Metal composite panels: Made of two or more materials (e.g., aluminum-plastic composite panels), combining metal rigidity and plastic processability by bonding aluminum sheets with plastic core layers tightly.
• Metal sandwich panel curtain walls: Equipped with metal face sheets and functional core materials (insulation, fireproof, etc.), ensuring structural strength while delivering excellent heat insulation and flame retardant performance.

1.2.2 By Surface Treatment Process

• Bright panels (smooth and high-brightness finish)
• Matte panels (understated texture)
• Profiled panels (three-dimensional shape formed by special processes)
• Corrugated panels (smooth lines and rhythmic appearance)

1.2.3 By Shape

• Perforated aluminum single panel curtain walls
• Shaped aluminum single panels (single-curved and double-curved)
• Carved aluminum single panels
• Curved aluminum single panels
• Column-clad aluminum single panels (cylindrical and square)
• Aluminum grid ceilings
• Aluminum hanging pieces

2. Surface Treatment Technologies for Aluminum Panels

2.1 Anodizing

• Oxide film thickness: Usually above 12μ
• Color characteristics: Limited color options (mainly antique bronze and white); slight color unevenness may occur even in the same batch of products
• Color difference cause: Not a production technology defect, but due to differences in aluminum sheet raw material batches and the difficulty in achieving completely consistent parameters (e.g., electrolytic bath solution concentration, current density) during the oxidation process, leading to minor color variations.
  

2.2 Electrostatic Spraying

• Powder spraying raw materials: Mainly polyurethane, polyacrylic resin, epoxy resin, etc., mixed with high color retention pigments
• Color advantages: Can be formulated into dozens of spray powders with different colors, providing a rich range of color options for building exteriors.
