The aluminum sheet standard sizes vary by region, industry standard, and specific applications.

The following are some common standard sizes of aluminum sheets:

• Thickness

The thickness of aluminum sheets is usually within the following ranges: 0.2mm, 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, 20mm, 25mm, 30mm, 50mm, etc.

• Width

The standard width of aluminum sheet is generally: 1000mm, 1200mm, 1220mm, 1500mm, 2000mm or other customized widths.

• Length

The standard length of aluminum sheet is usually: 2000mm, 2440mm, 2500mm, 3000mm, 4000mm, 5000mm, 6000mm, 8000mm or other customized lengths.

And the common used aluminum sheet standard sizes are:

– 4×8 feet (1220×2440 mm)

International universal size, easy to transport and process. Used in building curtain walls, interior decoration, and furniture manufacturing.

– 4×4 feet (1220×1220 mm)

Small size, suitable for fine processing. Used in small decoration projects and sign making.

– 4×10 feet (1220×3050 mm)

Increased length, reduced seams, and improved structural integrity.

Used in roof coverings and large building components.

– 24×48 inches (610×1220 mm)

Conforms to imperial units and is easy to connect with local standards.

Used in North America, industrial manufacturing, electronic equipment housing.

– 3×8 feet (914×2440 mm):

Commonly used in construction and signage.

– 5×10 feet (1525×3050 mm):

Truck trailers, RV bodies, marine applications.

Special aluminum sheet sizes

– Extra-wide and extra-long aluminum sheets

Widths up to 2500mm and lengths up to 12000mm, used for large building curtain walls and ship decks.

– Special-shaped aluminum sheets

Customized according to design requirements, such as wavy, bent, and perforated aluminum sheets.

International standards of aluminum sheet sizes:

– ASTM B209: American Society for Testing and Materials standard, which specifies the thickness, width, and length tolerances of aluminum sheets.

– EN 485: European standard, covering the mechanical properties and dimensional requirements of aluminum sheets.

Aluminum sheet size selection suggestions according to the application field:

– Architectural curtain wall: 1220mm×2440mm or 1500mm×3000mm is preferred.

– Transportation: customized according to the size of the carriage, such as 1250mm in width and 6000mm in length.

– Automotive sheet metal: 5 series or 6 series aluminum plates with a thickness of 1.2mm to 3.0mm are mostly used, with a width of 1000mm to 1500mm.

– Electronics industry: ultra-thin aluminum plates (0.1mm – 0.5mm), with a width of 900mm – 1250mm.

When designing and selecting aluminum sheets, factors such as processing technology, material strength, and weight must also be considered to ensure the performance and feasibility of the final product.
