The billboards and signs used on the streets are mostly
aluminum plates.<br><strong>Aluminum plate </strong>is a popular material for making billboards. More than 80% billboards on the market are made of
aluminum plates.<br>
There are two kinds of
aluminum plates for making signs, pure
aluminum plates and
aluminum alloy plates. The price of pure
aluminum plate is lower, but the hardness is not as good as that of
aluminum alloy plate. Now most of the domestic signs are made of pure
aluminum plate, the main brands are 1050 and 1060 two kinds, the thickness is generally concentrated in 1, 1.5, 2, 2.5, 3.0mm, the general width in the 1000mm-2000mm, the length of 2000mm.<br>
If it is a circular sign, the <strong>aluminum circles</strong> thickness is basically around 2.0mm. Some billboards also need surface oxidation treatment, which is also common.<br>
The strength, hardness and reflectivity of alloy
aluminum plate are much stronger than that of pure
aluminum plate. Alloys will gradually replace pure aluminum and become the main material of signs.<br></p>
