| Total panel thickness | Commonly 2.5 mm, 3 mm, 4 mm, 5 mm and 6 mm; project-specific options can be discussed | Influences rigidity, weight, fabrication behavior and suitability for the support system. |
| Aluminum skin thickness | Approx. 0.08 mm to 0.50 mm depending on grade and application | One of the most important cost and performance variables. It should be stated clearly for both face and back skins. |
| Standard sheet size | 1220 × 2440 mm is widely used; other widths and lengths may be available | Impacts cutting yield, joints, container loading and fabrication efficiency. |
| Core | PE core, fire-retardant mineral-filled core and other project-based structures | Influences fire behavior, weight, processing and overall panel cost. |
| Coating | PE, PVDF and selected decorative surface systems | Should match indoor or outdoor exposure, color-retention expectations and cleaning environment. |
| Surface finish | Solid, metallic, high gloss, brushed, mirror, wood, marble, digital printing and custom appearance options | Determines the visual effect and may change forming, handling and protective-film requirements. |
| Gloss & color | Standard color range or project color matching subject to sample approval | Physical approval helps reduce interpretation differences between digital color references and production. |
| Protective film | Standard or customized film, printing and peel direction options subject to confirmation | Protects the face during cutting, transport and installation; film selection must suit the coating. |
| Packing | Stacked sheets, edge protection, palletized or reinforced export packing | Should reflect sheet size, shipment route, unloading method and storage conditions. |
