As a commonly used building decoration material, the performance and quality of aluminum composite panels are directly related to the aesthetics and durability of the project. In aluminum composite panels, the aluminum skin, as the outer material, not only affects the overall appearance of the panel, but also plays an important role in protecting the internal materials and enhancing the strength of the panel. The conventional recommended thickness is generally chosen between 0.2㎜ and 0.5㎜. Different thicknesses of aluminum and panel thicknesses have different characteristics and applicable occasions. When selecting, purchase according to actual needs. Therefore, the choice of aluminum skin thickness is particularly important. We usually use "mm" to measure this unit. Commonly used upper and lower aluminum thicknesses are: 0.05/0.05mm, 0.08/0.08mm, 0.10/0.10mm, 0.12/0.12mm , 0.15/0.15mm, 0.18/0.18mm, 0.21/0.21mm, 0.25/0.25mm, 0.30/0.30mm, 0.40/0.40mm, 0.50/0.50mm and other different specifications.
The thinner the aluminum skin, the higher the risk of breakage of the slotted hems. On the contrary, the thicker the aluminum skin, the slotted and folded edge will not break even if it is folded several times, and the flatness of thin aluminum skin is not good. The thicker the aluminum skin, the higher the flatness. These aluminum skins of different thicknesses can meet various engineering projects demand, when the thickness of the aluminum skin reaches more than 0.25/0.25mm, the thickness of the panel usually reaches 4mm.
For large building curtain walls, roofs, ceilings, partitions, etc., the optional panel thickness is 4-6mm, and the upper and lower aluminum thickness is 0.50/0.50mm aluminum skin thickness, which has better wind pressure resistance and higher safety factor. When making aluminum composite panel curtain walls, aluminum skin with a thickness of 0.50/0.50mm is usually selected. For a few engineering projects, due to cost budget considerations, a thickness of 0.4/0.40mm can be selected. This type of aluminum composite panel is relatively balanced and has sufficient Strength without adding too much weight. Its surface has a good decorative effect after being sprayed, baked, etc.
For outdoor production of signs, billboards, posters, etc., you can choose lighter aluminum skin thicknesses of 0.30/0.30mm, 0.21/0.21mm or 0.18/0.18mm. This kind of aluminum composite panel has rich colors, low cost, and is popular among Welcomed by billboard manufacturers, currently, customers in Europe, North America, South America, the Middle East, Southeast Asia and other regions purchase HUABOND® aluminum composite panels in large quantities as the basic panels for billboards.
The thickness of the aluminum skin of aluminum composite panels is an important parameter to measure the performance of aluminum composite panels. To sum up, the most common aluminum thicknesses on the market mainly include curtain wall materials and advertising materials according to industry classification. The aluminum thickness used for curtain wall materials is: 0.40/0.40mm- 0.50/0.50mm; the aluminum thickness used for advertising materials is: 0.15-0.15mm- 0.30/0.30mm. Purchase according to actual needs when selecting.
