4×8 aluminum sheet is a common size of aluminum sheet plate, 4 feet wide and 8 feet long, it is considered a standard size aluminum plate, often called 4×8 aluminum sheet;
4×8 aluminum sheet plate is deeply loved by consumers because of its convenient size for production and transportation, as well as for use after purchase;
4×8 aluminum sheet is widely used, often used in construction, automobile manufacturing, truck box, bus skin, hull skin, Anti-slip ramps and stairs, etc.
4×8 foot is an imperial unit, and converting it to SI units is:
1 foot(′) = 12 inch(”) = 304.8 mm
4 feet = 1219.2 mm ≈ 1219 mm
8 foot = 2438.4 mm ≈ 2438 mm
In the production of 4×8 aluminum plate, some customers will also set the length and width as 1220x2440mm for convenience, that is, the size of 4×8 aluminum plate can also be roughly considered as 1220x2440mm.

Similar to 4×8 aluminum sheets, other common aluminum sheet sizes are:
The above size is the common size of aluminum sheet plate. Huawei Aluminum supports customized aluminum plate size. The width range is 100mm-2600mm, and the length is not limited. It can be produced in the form of coil.
The production process of 4×8 aluminum sheet plate is basically the same as that of regular size aluminum plate. The following is the detailed production process of aluminum plate:
(1) Ingredients: Calculate the addition amount of various alloy components according to the specific alloy grades to be produced, and reasonably match various raw materials.
(2) Smelting: Add the prepared raw materials into the smelting furnace according to the process requirements and heat them to 950°C-1200°C for melting, and effectively remove the impurities and gas in the melt by means of degassing and slag removal refining.
The melting point of aluminum is around 660°C
(3) Casting: The smelted aluminum liquid is in a certain casting process, including casting, extrusion and fish on-line, including: oxidation, electrophoretic coating, fluorocarbon spraying, powder coating, grain wood transfer, etc.) three processes.
The cast aluminum plate also needs to be processed to obtain better material properties. This process is rolling, also called calendering.
Rolling can be considered as the following two types:
Cold rolling refers to the process of compressing and deforming metal billets by rolling force at room temperature to improve their strength, hardness and dimensional accuracy, and to achieve thinning, homogenization and smoothing of metal materials.
Cold rolling can not only realize the thinning of metal materials, but also improve the precision, strength, hardness and surface finish of materials, which is a very important method in metal processing.
Cold rolling is processed at room temperature and will not cause thermal effects on metal materials, so precise control of materials can be achieved.
Hot rolling is the process of compressing, bending and forming metal sheets or strips at high temperatures to finally obtain metal products with the desired shape and properties.
In the hot rolling process, metal sheet heated to certain temperature, usually above the recrystallization temperature. Then fed into rolling mill where they are rolled several times at high temperatures, gradually forming them into the desired shape and thickness.
During the rolling process, the temperature of the metal sheet or strip is usually kept above 800°C.
The hot rolling process has many advantages, such as high production efficiency, low cost, and high material utilization rate. Therefore, it is widely used in the field of metal processing.
Rolled aluminum and aluminum alloy materials are available in coil form.
After the 4×8 aluminum sheet is rolled, it still needs further processing to improve its strength and plasticity. Stretching is required here, and the rolled aluminum sheet is put into a stretching machine for processing.
During the stretching process, attention should be paid to key points such as stretching speed, temperature, and stretching degree to ensure that the mechanical properties of the 4×8 aluminum sheet plate meet the requirements.
After finishing the anodizing and coating treatment, the aluminum plate needs to be cut and surface treated. Cutting can adopt methods such as laser cutting, water jet cutting or mechanical cutting according to needs.
The cut aluminum plate needs surface treatment to eliminate the burrs and sharp angles left by cutting, and improve the safety and aesthetics of the aluminum plate.
Polishing treatment refers to polishing the surface of the aluminum plate to a mirror state by mechanical means, which can enhance the decorative effect and reflective performance of the aluminum plate.
Anodizing is the most commonly used method in surface treatment of aluminum sheets. In this method, an aluminum plate is used as an anode, and an oxide film is formed on the surface of the aluminum plate by electrolysis, and the film has high hardness and good corrosion resistance.
Powder coating
Powder coating is an advanced and efficient coating process. Its basic principle is to spray plastic powder on the surface of the workpiece and heat it to melt to form a uniform coating.
Powder coating has the following advantages: dense coating, corrosion resistance, wear resistance, rich color and long-lasting color, suitable for coating various metals, plastics, wood and other materials.
Roller Coating
Roller coating is a more traditional method of coating application. It uses a roller to spread the paint evenly on the surface of the workpiece.
The advantage of roller coating is that the construction is simple, fast, and the cost is low, and it is suitable for the coating of large area walls. However, compared with powder spraying, the coating quality of roller coating may not be as good as the former, and the color is not rich enough.
When choosing powder spraying and roller coating, it is necessary to make a trade-off according to specific application scenarios and requirements.
After cutting and surface treatment, the final quality inspection of the aluminum sheet is required. Quality inspection includes checking the size, thickness, surface quality and other aspects of the aluminum plate.
Aluminum sheets that meet the requirements will be packaged and shipped to customers. The main processes of packaging are:
The packaged 4×8 aluminum sheets will be shipped to Shanghai or Qingdao port, and sent to the country where the customer is located.

The formula for calculating the weight of the aluminum sheet is:
weight = volume x density
Notice:
The density of the aluminum sheet is 2.7g/cm³
Foot (ft) 1 foot = 12 inches = 30.48cm = 304.8mm.
Inch (in) 1 inch=2.54cm==25.4mm.
volume = length x width x thickness
4 feet = 1219 mm ≈ 122cm
8 feet = 2438 mm ≈ 244cm
1/8 Inch = 3.175 mm = 0.3175cm
Inserting the formula yields:
Volume = 122cm x 244cm x 0.3175cm ≈ 9451cm³
4×8 aluminum sheet of 1/8 inch weight is
Weight = 9451cm³ x 2.7g/cm³ = 25517.7g ≈ 2.55kg

Aluminum foil and tin foil are two common metal sheet materials. They are similar in appearance, both have a silver-white metallic luster, and are often used in daily life to wrap food, perform baking or grilling and other cooking operations.
7075 aluminum alloy is a high-strength aluminum alloy. It belongs to the Al-Zn-Mg-Cu alloy series and is a representative product of the 7000 series aluminum alloy.
Although aluminum and aluminum alloys both use aluminum as the main synthetic element, they have great differences in certain physical and chemical properties.
Aluminum is named after the Latin word "alumen", which means "bitter earth" or "alum". The name was first proposed by Swedish chemist Jons Jakob Berzelius around 1825 to describe the properties of this metal oxide.
