　　<strong>3mm thick aluminium sheet</strong> sizes include 1200mm*2400mm, 1000mm*2000mm and 1220mm*1440mm-1500mm*4500. Usually the maximum width is 2650mm and the biggest length is 16000mm, but most of the time, the width is around 1000mm and length around 2500mm. Most suppliers are able to supply the regular sizes mentioned above, only really powerful ones can provide sheets of 2650mm wide and 16000mm long.<br></p>

　　If it is aluminum hot extrusion, the maximum section width is about 300 mm under the condition of low flatness requirement. If it is aluminum plate and belt processing technology, it is hard to say that the production capacity of the equipment can reach the maximum dimension. Most of them are 12 meters to 1.5 meters wide and over 100 meters long.</p>

　　Before checking <strong>3mm aluminium sheet sizes</strong> in production, the production unit would first look at the tolerance standard note. If no tolerance is indicated, see the accuracy grade of the work piece. Check the tolerance table. If the level is not noted and the size of the non-important attack is 3-4 mm deviation is also acceptable. If the accuracy is lower, the size can be increased. It ‘s just that the board type is generally the deviation of zd going down.</p>

　　In addition to regular standards, 3mm thick aluminium sheet sizes entail other standards if they are of special surface treatment processes. For example, the common specification of color coated aluminium is 1.22mx2.4m, with a thickness of 3-5mm. It is divided into single-sided and double-sided. According to the thickness of aluminum skin, there are 8-30 wires and other specifications. According to the use, there are two kinds of indoor and outdoor use. There are also polyester plate and carbon plate. If it is an outdoor plate, it can be customized, with a maximum length of 6m.</p>
