VI. Frequently Asked Questions (FAQs)
Q1: What are the core differences in alloy selection between aluminum discs for indoor ceilings and outdoor curtain walls?
A1: Core differences lie in strength and weather resistance. For indoor non-load-bearing ceilings, 1050/1060 pure aluminum is preferred for good formability and low cost. For outdoor curtain walls, 3003/5052 alloys are used—3003 resists corrosion, 5052 offers higher strength, adapting to complex outdoor environments.
Q2: How to adapt aluminum disc surface treatment methods to different climatic regions?
A2: ① Coastal areas: PVDF fluorocarbon spraying (20+ year warranty). ② High-temperature areas: PVDF or anodizing (UV-resistant). ③ Indoor dry areas: Powder coating/thermal transfer (cost-effective). ④ Humid bathrooms: Anodizing (waterproof).
Q3: How to avoid deformation of large-size aluminum discs (diameter over 1.5m) used in outdoor landscapes?
A3: Use 5052 H32 alloy (≥3.0mm thick), conduct aging treatment to eliminate internal stress, adopt multi-point fixing with 2-3mm/m expansion gaps, and apply passivation before spraying to prevent deformation.
Q4: What impact do the thickness and diameter tolerances of aluminum discs have on decorative splicing effects?
A4: Excessive tolerance causes uneven gaps, height differences, and loose buckles. Control diameter tolerance ±0.5mm and thickness ±0.05mm; require factory test reports and choose high-precision cold-rolled discs.
Q5: What special requirements must aluminum discs meet when used as bathroom drain covers?
A5: Meet waterproof, anti-slip, and corrosion-resistant requirements. Choose 1060/3003 alloy (1.5-2.5mm thick), anodize with ≥0.3mm anti-slip texture, and design 30%-40% perforation rate (5-8mm aperture) with rounded edges.
Q6: Aluminum discs have high recyclability—will this affect their decorative performance in secondary use?
A6: No. Recycled aluminum discs, after remelting and purification, have similar performance to primary aluminum. They are processable and applicable to decorations, with lower carbon footprint, complying with green standards.
Q7: How to avoid damaging the surface coating when installing aluminum discs?
A7: Wrap with protective film when handling, use rubber-gasketed tools, finish surface treatment before installation, and touch up damaged coating promptly with matching paint.
VII. Summary
The application of aluminum discs in architectural decoration is evolving from traditional simple decoration to the integration of functionality and aesthetics. From indoor ceilings and wall decorations to outdoor curtain walls and landscape installations, their diversified specifications and surface treatment solutions make them an indispensable material in modern architectural design. Mastering the selection logic of alloys, surface treatments and specifications, and avoiding deformation, corrosion and other issues according to scenario needs, can ensure decorative effects while improving project durability and cost-effectiveness.
