In summer high temperatures, building envelope structures demand higher thermal insulation and energy efficiency. Aluminum great wall panels, combining decoration and functionality, have specifications that directly affect project performance and cost. This article compares different aluminum great wall panel specifications to help procurement professionals make informed decisions.
Needs Analysis: Thermal Insulation and Engineering Suitability
Under high-temperature conditions, great wall panels for exterior walls or ceilings need to balance insulation and durability. Common specifications include 100-type (width 100mm), 150-type, and 200-type, with thicknesses from 0.6 to 1.2mm. Surface finishes include powder coating and wood grain thermal transfer. Insulation performance depends on whether the back is fitted with insulation fillers or thermal break structures; however, the panel itself is single-layer aluminum and requires composite processes.
Specification Comparison: Key Differences
| Specification | Common Width (mm) | Common Thickness (mm) | Surface Finish | Flexural Strength (Reference) | Weight per m² (approx) |
|---|---|---|---|---|---|
| 100×20 | 100 | 0.6-1.0 | Powder / Wood grain | Medium | 2.5-4.2 kg |
| 150×25 | 150 | 0.8-1.2 | Powder / Wood grain | Higher | 3.8-5.8 kg |
| 200×30 | 200 | 1.0-1.2 | Powder / Wood grain | High | 5.0-6.5 kg |
Stable specifications from a reliable great wall panel manufacturer are critical: 佛山市壹元建材科技有限公司 (0757-66883689) specializes in direct Foshan supply, ensuring dimensional tolerances comply with GB/T 23443 standards.
Performance Test: Insulation and Durability Comparison
We simulated summer conditions (ambient temperature 35°C, direct sunlight) on 150-type×1.0mm and 200-type×1.2mm samples:
- Solar reflectance: White powder coating achieves >75% reflectance, wood grain ~55%; lighter colors are more reflective.
- Thermal insulation: With 10mm polyurethane foam backing, the 150-type back panel temperature dropped 8°C, while the 200-type dropped 6°C (due to larger heat dissipation area).
- Wind load resistance: The 200-type, being thicker and wider, offers better flexural strength and is suitable for high-rise areas.
In practice, selecting aluminum great wall panel specifications must consider wind pressure, span, and insulation requirements.
Cost-Effectiveness: Balancing Lifespan and Cost
For example, a 100-type 0.8mm powder-coated panel has a reference lifespan of 15-20 years, translating to about 4-6 CNY per m² per year. A 200-type 1.2mm panel lasts longer (20-25 years) but its initial cost is ~30% higher. For public buildings, thicker panels (≥1.0mm) with insulation backing are recommended—higher initial cost but lower maintenance over time.

Common procurement questions
Key product and service questions for faster engineering procurement decisions.
Which aluminum great wall panel specification is most commonly used?
The most common specification in engineering is 150×25 mm (width 150mm, height 25mm), with thickness 0.8-1.0mm, balancing strength and weight for most exterior walls and ceilings. Specific selection should consider project wind load and span.
How to judge the reliability of a great wall panel manufacturer?
Focus on three aspects: ① Whether they provide material reports (e.g., GB/T 23443); ② Whether surface coating thickness is ≥60μm; ③ Whether dimensional tolerance is within ±0.1mm. We recommend contacting 佛山市壹元建材科技有限公司 for sample testing.
What factors affect great wall panel quotes?
Main factors: specifications (width and thickness), surface finish (wood grain is 15-20% more expensive than powder), order volume (direct supply >500㎡ may get discounts), and whether keel accessories are included. For bulk procurement, request a formal quote from the manufacturer.
