Different applications have different requirements for the thickness of aluminum sheets sometimes. Common aluminum plate thicknesses are 1, 2, 3, 4, 5, 6, 8, 10, 15 mm, etc. , especially the 2mm aluminum plate. For the same alloy, 2mm aluminum sheets are also cheaper. Let's see its common usage.

road sign
Circular and triangular traffic sign materials generally use 1.2 mm, 1.5 mm and 2 mm 4x8 aluminum sheet. For large road signs and highway signs, aluminum sheets with a thickness of 2.5 or 3 mm are required. 1060 or 3003 aluminum sheets are common choices.
Aluminum solid plate
The aluminum solid board can choose different thicknesses according to different architectural decoration requirements. The conventional thickness is 1.5mm, 2.0mm, 2.5mm, 3.0mm, the thickness of aluminum plate for outdoor building decoration is generally 2.5mm, 3mm; the thickness of 2.0mm can be selected for indoor decoration; the thinnest 1.5mm can be selected for indoor ceiling decoration.
shipbuilding
Marine aluminum plate generally refers to aluminum-magnesium alloy. At present, the commonly used aluminum plate is 5083 aluminum plate, such as 5083H116 aluminum plate and 5083H321 aluminum plate. Common thicknesses are 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, etc.
aluminum body
On the premise of ensuring the rigidity, strength and safety performance of the car, by changing the materials of the car structure and parts, lightweighting helps to improve the fuel efficiency of the car and reduce the emission of pollutants. 5052 aluminum sheets with a thickness of 0.75 Aluminum Plate are usually used for the front and rear panels of automobiles.
aluminum pedal
Aluminum pedals reduce the risk of slipping. It is commonly used in stairs, walks, walkways, ramps, treads for ambulances and fire trucks, and other applications include truck floors and trailer floors. The main alloys are 1100, 1200, 3003, 3105, 5005, 5083, 5052, 5083, 6082, 5251, 5454, 6061 and so on.
