Product Details
Aluminium sheet plate is widely used in construction, transportation, engineering, and industrial fabrication. One of the most important specifications for aluminum products is size standardization, including thickness, width, and length. These dimensions directly affect processing method, weight, and application.
1. Standard Thickness Range of Aluminium Sheet Plate
Aluminium sheet and plate products are generally classified by thickness:
| Category | Thickness Range | Application Type |
|---|---|---|
| Thin sheet | 0.2 mm – 3 mm | Decoration, packaging, light fabrication |
| Medium sheet | 3 mm – 6 mm | General industrial use |
| Plate | 6 mm – 200 mm+ | Structural and heavy-duty applications |
2. Common Standard Width Sizes
Aluminium sheet plates are typically produced in the following widths:
- 1000 mm
- 1250 mm
- 1500 mm
- 2000 mm
- 2500 mm (less common, heavy plate)
These widths are based on rolling mill standards to ensure efficient production and material utilization.
3. Common Standard Length Sizes
Standard aluminum sheet lengths vary depending on thickness and application:
- 2000 mm
- 2500 mm
- 3000 mm
- 4000 mm
- 6000 mm (industrial plate size)
Longer plates are typically used in:
- Shipbuilding
- Structural engineering
- Large equipment manufacturing
4. Common Standard Sheet Combinations
Typical commercial aluminum sheet sizes include:
| Thickness | Width × Length |
|---|---|
| 1–3 mm | 1250 × 2500 mm |
| 3–6 mm | 1500 × 3000 mm |
| 6–10 mm | 2000 × 4000 mm |
| 10–50 mm | 2000 × 6000 mm |
5. Custom Cutting Sizes
In addition to standard formats, aluminium sheet plates can be customized through processing:
- CNC cutting
- Laser cutting
- Shearing
- Waterjet cutting
Custom sizes are used for:
- Mechanical parts
- Engineering structures
- OEM manufacturing
6. Why Aluminium Sheet Sizes Are Standardized
Standard dimensions are designed to:
- Improve rolling efficiency
- Reduce production cost
- Simplify transportation and storage
- Match global fabrication equipment standards
7. Thickness vs Size Relationship
As thickness increases:
- Width and length options become more limited
- Handling becomes more difficult
- Plate weight increases significantly
This is why large-size thick plates are mainly used in industrial and structural applications.
