How to look at the specifications of aluminum-plastic panels
As a common building decoration material, aluminum-plastic panels are widely used in exterior walls, interior decoration, billboards and other fields. Understanding the specifications of aluminum-plastic panels is crucial for purchase and use. This article will introduce the specifications and parameters of aluminum-plastic panels in detail, and attach a structured data table to help you quickly master relevant knowledge.
1. Basic structure of aluminum-plastic panels
Aluminum-plastic panels are composed of three layers of materials, namely:
1.Upper aluminum plate: Usually pure aluminum or aluminum alloy, thickness between 0.1mm-0.5mm.
2.middle plastic core layer: Mostly polyethylene (PE) or fireproof core material (FR), with a thickness between 1.5mm-5mm.
3.Lower aluminum plate: Symmetrical with the upper aluminum plate and the same thickness.
2. Core specifications of aluminum-plastic panels
| Parameter name | Common specifications | Description |
|---|---|---|
| total thickness | 3mm/4mm/5mm/6mm | The most commonly used specifications, selected according to use |
| Aluminum layer thickness | 0.1mm/0.15mm/0.2mm/0.3mm/0.5mm | The thicker the aluminum layer, the higher the strength and the more expensive it is |
| Core material type | PE/FR/PVC | PE is an ordinary core material and FR is a fireproof core material. |
| Standard size | 1220mm×2440mm/1250mm×2500mm | The most common length and width specifications |
| surface treatment | PVDF/PE/PET | PVDF coating is the best and has strong weather resistance |
3. How to choose suitable aluminum-plastic panel specifications
1.Choose according to the usage environment:
- Outdoor exterior walls: It is recommended to choose a thickness of 4mm or more, PVDF coating, aluminum layer thickness ≥0.2mm
- Interior decoration: 3mm thickness can be selected, PE coating is enough
- Billboard: recommended to be 4mm or above, aluminum layer thickness ≥ 0.3mm
2.Choose according to fire protection requirements:
- General places: ordinary PE core materials can be used
- Places with high fire protection requirements: FR fireproof core materials must be used
4. Comparison of common technical parameters of aluminum-plastic panels
| Model | Total thickness(mm) | Aluminum layer thickness (mm) | core material | Suggested uses |
|---|---|---|---|---|
| Standard type | 3 | 0.1+0.1 | PE | interior decoration |
| Enhanced | 4 | 0.15+0.15 | PE | outdoor advertising |
| Fireproof type | 4 | 0.2+0.2 | FR | public building |
| High-end | 5 | 0.3+0.3 | FR | High-end curtain wall |
5. Things to note when purchasing aluminum-plastic panels
1.View product test report: Regular products should provide test reports such as fire protection grade and weather resistance.
2.Check surface quality: The surface of high-quality aluminum-plastic panels should be smooth without scratches, and the coating should be even and without bubbles.
3.Pay attention to the thickness of the aluminum layer: Some low-price products will reduce the thickness of the aluminum layer and affect the service life.
4.Consider color difference issues: Aluminum-plastic panels of the same batch should have no obvious color difference.
6. Price range reference for aluminum-plastic panels
| Type | Price range (yuan/㎡) | Description |
|---|---|---|
| Ordinary 3mm | 50-80 | Indoor use |
| Standard 4mm | 80-120 | General outdoor |
| Fireproof 4mm | 120-180 | public places |
| High-end 5mm | 180-300 | high-end building |
Summary: Understanding the specifications of aluminum-plastic panels is very important for purchase and use. It is recommended to select the appropriate specification based on specific use, environment and budget. At the same time, be sure to choose products produced by regular manufacturers to ensure quality and safety.
