Aluminum Plate Weight Chart 4mm and 5mm Sheet Weight per Square Meter

When selecting aluminum sheets for construction, fabrication, transportation, marine equipment, signage, or industrial components, weight is one of the most important specifications to consider. The weight of an aluminum plate affects material handling, shipping costs, structural loading, machining requirements, and final product performance.

For buyers comparing 4mm aluminum plate and 5mm material, calculating weight per square meter provides a simple and reliable starting point. This guide explains how aluminum sheet weight is calculated, provides a practical weight chart, and discusses the factors that may influence actual plate weight.

How to Calculate Aluminum Plate Weight

The standard formula for calculating aluminum sheet or plate weight is:

Weight = Length × Width × Thickness × Density

For metric measurements:

Weight (kg) = Area (m²) × Thickness (mm) × Density (g/cm³)

Aluminum has an average density of approximately 2.70 g/cm³, or 2,700 kg/m³. Although the density can vary slightly among alloys, such as 1050, 1060, 3003, 5052, 5083, 6061, and 7075, 2.70 g/cm³ is generally accurate enough for estimating the weight of standard aluminum sheets.

A one-square-meter aluminum plate with a thickness of 1 mm weighs approximately:

2.7 kg per m²

Therefore, the weight can be calculated quickly by multiplying thickness in millimeters by 2.7.

For example:

4 mm aluminum sheet: 4 × 2.7 = 10.8 kg/m²

5 mm aluminum sheet: 5 × 2.7 = 13.5 kg/m²

This easy calculation is especially useful when estimating the total weight of multiple sheets or custom-cut aluminum parts.

Aluminum Plate Weight Chart Per Square Meter

The following chart shows approximate aluminum sheet weight per square meter based on a density of 2.70 g/cm³.

According to the chart, a 4mm aluminum plate weighs about 10.8 kilograms per square meter. A 5 mm plate weighs approximately 13.5 kilograms per square meter. The difference is 2.7 kg/m², which may seem small for a single panel but becomes significant in large projects, truck bodies, marine structures, curtain walls, trailers, and machinery enclosures.

4mm Aluminum Plate Weight Calculation

A 4 mm aluminum plate is widely used where moderate strength, corrosion resistance, and a relatively low overall weight are required. Common applications include vehicle panels, decorative cladding, protective covers, machine guards, signs, storage tanks, and architectural elements.

The basic calculation is:

1 m × 1 m × 4 mm aluminum = 10.8 kg

Here are several common sheet sizes and their estimated weights:

For a 1220 × 2440 mm sheet, the area is approximately 2.98 m². Multiplying 2.98 by 10.8 kg/m² gives an estimated weight of around 32.1 kg.

The actual weight may vary slightly because of thickness tolerances, alloy composition, surface finish, and manufacturing standards.

5mm Sheet Aluminium Weight Calculation

A 5mm sheet aluminium product offers greater rigidity and load-bearing capacity than 4 mm material. It is frequently used in industrial flooring, truck beds, marine platforms, pressure vessels, tooling plates, heavy-duty enclosures, and structural fabrication.

The calculation for a 5 mm sheet is:

1 m × 1 m × 5 mm aluminum = 13.5 kg

Below are estimated weights for several popular dimensions:

A 5 mm plate measuring 1500 × 3000 mm has an area of 4.5 m². At 13.5 kg per square meter, its total estimated weight is 60.75 kg.

This increased weight should be considered when planning lifting equipment, packaging, warehouse storage, and transportation. For larger orders, even a 1 mm difference in thickness can add hundreds of kilograms to the total shipment weight.

Does Aluminum Alloy Affect Weight?

Different aluminum alloys have slightly different densities. For example, commercially pure aluminum alloys such as 1050 and 1060 are close to 2.70 g/cm³. Some magnesium-containing alloys, including 5052 and 5083, may be marginally lighter or heavier depending on composition. High-strength alloys such as 6061 and 7075 also have small density differences.

However, these variations are generally minor for standard quotation and logistics estimates. In most cases, using 2.7 kg per square meter per millimeter of thickness is sufficient.

If precise engineering calculations are required, especially for aerospace, marine, or load-critical structures, it is best to confirm the exact alloy density and mill test certificate data with the supplier.

Choosing Between 4mm and 5mm Aluminum Plate

The choice between 4 mm and 5 mm aluminum plate depends on the balance between strength, stiffness, cost, and weight.

Choose a 4 mm plate when:

Lower material weight is important

The application has moderate loading requirements

Easier bending and fabrication are needed

Shipping and handling costs need to be reduced

Choose 5 mm sheet aluminium when:

Higher rigidity is required

The sheet will support greater loads

Improved impact resistance is needed

The application involves industrial or structural use

In summary, a 4mm aluminum plate weighs approximately 10.8 kg per square meter, while 5mm sheet aluminium weighs around 13.5 kg per square meter. Understanding these figures helps buyers estimate project costs, choose appropriate handling methods, and select the right thickness for each application.
