1. Classification by alloy composition
High-purity aluminum plate
Aluminum content ≥ 99.9%, representative grades 1050, 1060, 1100, etc., suitable for decoration scenes with high corrosion resistance requirements.
Features: excellent ductility, but low strength, need to be used with reinforcement ribs.
Alloy aluminum plate
Common grades: 3003 (aluminum-manganese alloy), 5052 (aluminum-magnesium alloy), 6061 (aluminum-magnesium-silicon alloy), etc., with both strength and processing performance;
Application: scenes requiring high load-bearing capacity such as curtain walls and industrial equipment.
Composite aluminum plate
Composite different materials (such as aluminum-plastic core materials) through brazing or cladding processes to enhance sound insulation and heat insulation performance.

| Category | Thickness Range | Typical Applications |
|---|---|---|
| Thin Plate | 0.15 – 2.0 mm | Indoor ceilings, artistic decoration, micro-aperture designs |
| Conventional Plate | 2.0 – 6.0 mm | Building curtain walls, outdoor shading systems, general architectural use |
| Medium/Thick Plate | 6.0 – 25.0 mm | Industrial protective covers, heavy-duty ventilation systems, structural panels |
3.Classification by perforation technology
CNC punching plate
Adopt CNC punching machine to batch process regular hole types such as round holes and square holes, with an error of ≤0.1mm, suitable for standardized projects.
Laser punching plate
Supports complex artistic hole types (plum blossom holes, gradient patterns), with an accuracy of ±0.05mm, but the cost is relatively high.
Heavy punching plate
Thickness ≥4.0mm, with large aperture (such as 10-30mm) design, used for industrial filtration or guardrails.
4. classification by hole type and arrangement method
Regular hole type
Round hole: hole diameter 2.5-35mm, densely arranged to form a light-transmitting texture;
Square hole/diamond hole: hole diameter 5-20mm, enhance ventilation efficiency, used for ventilation ducts.
Artistic hole type
Plum blossom hole, hexagonal hole: achieve light and shadow gradient effect through parametric design, commonly seen on building skin;
Special-shaped hole (fish scale pattern, wave pattern): requires laser cutting customization to enhance the uniqueness of decoration.
Functional hole type
Micropore (aperture ≤3mm): used for precision filtration or acoustic noise reduction structure;
Louvre hole: has both sunshade and wind guide functions, suitable for ecological building facades.
Selection considerations :
Curtain wall projects give priority to 5052/3003 alloy + fluorocarbon spraying, thickness ≥2.5mm to ensure durability;
Art installations recommend laser cutting technology + high-purity aluminum plate (1100/1050) to achieve high-precision complex patterns
