4×8 is a common size of aluminum sheet, also written as 4ft x 8ft aluminum sheet. 4×8 is expressed in inches, which is equivalent to 1220*2440mm aluminum sheet when converted to millimeters.
For example, 3mm 4×8 aluminum sheet refers to an aluminum sheet with a thickness of 3mm, a width of 1220mm, and a length of 2440mm. This article mainly explains the specifications, advantages, and price influencing factors of 4×8 sheet of 1/8 inch aluminum.
4×8 sheet of 1/8 inch aluminum standard size advantages
4×8 sheet of 1/8 inch aluminum is the most commonly used and popular specification, mainly because of the many advantages brought by its standardized size.
Standardization and wide availability
- 4×8 inches is the standard stock size for aluminum sheet manufacturers and suppliers in North America and many parts of the world.
- The price is relatively transparent and competitive.
- 4×8 inch aluminum sheet is relatively easy to purchase. Most metal suppliers have it in stock, no special customization is required, and the delivery cycle is short.
Optimize transportation and handling
- 4×8 inches is suitable for standardized truck, container and pallet transportation, with high transportation efficiency and low cost.
- For manual handling, 4×8 feet is easy for two people to operate collaboratively and is convenient for moving around the factory.
Efficient processing and installation
- In the construction, manufacturing and processing industries, most designs and structures are based on 4×8 feet module planning, such as wall panels, ceilings, partitions, equipment housings, etc. Using standard size panels can minimize cutting waste and improve material utilization.
- Walls, roofs, fences, etc. that need to cover a large area, standard size panels can be quickly laid and installed, reducing joints and improving construction efficiency.
Reduce material waste and cost
- Less cutting waste, high material utilization, and reduced raw material costs.
- Reduce additional costs caused by special size customization.
Convenient inventory management
For suppliers, distributors and large users, standard sizes simplify inventory management, stacking and warehousing planning.

How heavy is 1/8 ft aluminum sheet?
To calculate the weight of a 4×8 aluminum plate, we need to know the calculation formula and the thickness of the aluminum plate.
There are usually two ways to calculate the weight of a 4×8 1/8 inch aluminum plate: Use a measuring tool to measure the weight of the aluminum plate. Use the weight calculation formula to get the weight, provided that you know the length, width and thickness of the aluminum plate. Weight = aluminum plate density × aluminum plate volume.
Table2：
| Thickness | Al Sheet Type | Density | Volume | Weight |
| 1/16 ( inch) | 4×8 aluminum sheet | ρ=2.7g/cm³ | 4726cm³ | 12.759Kg |
| 1/8 (inch) | 4×8 aluminum sheet | ρ=2.7g/cm³ | 9451cm³ | 25.518Kg |
| 1/4 (inch) | 4×8 aluminum sheet | ρ=2.7g/cm³ | 18902cm³ | 51.036Kg |
| 1/2(inch) | 4×8 aluminum sheet | ρ=2.7g/cm³ | 37805cm³ | 102.072Kg |
Through the calculation formula, the weight of 4×8 aluminum plates of different thicknesses can be easily obtained. For example: the weight of 3×16 aluminum plate 4×8 is 38.277kg; the weight of 4×8 1/4 inch aluminum plate is 51kg.
4×8 sheet of 1/8 inch aluminum price
People in the aluminum industry know that the price change of aluminum plates depends on the price of aluminum ingots and the processing fee of aluminum plants. So what aspects should customers focus on when buying aluminum plates in the market, and how to choose?
Aluminum ingot price
The fluctuation of aluminum plate prices is affected by the price of aluminum ingots, and the change of aluminum ingot prices directly determines the price of aluminum plates. Aluminum ingots are the raw materials for producing aluminum plates. The price of aluminum ingots changes every day in the market, so the production cost of manufacturers also changes with the price of aluminum ingots.
Process and alloy
There are 8 series of aluminum alloys, hundreds of grades, and the thickness ranges from less than 1 mm to tens of centimeters. The thicker the thickness, the higher the price. At the same time, different production processes also determine the cost, such as hot rolling is more expensive than cold rolling. The following are the processing costs of different series of aluminum plates.
Table3：
| Alloy | Processing |
| 1060 | 1600RMB |
| 3003 | 7900RMB |
| 5052 | 2800RMB |
| 5083 | 3200RMB |
| 6061 | 4000RMB |
