Third, the 3000 series aluminum plate represents 3003 3003 3A21. Can also be called rust-proof aluminum plate Our 3000 series aluminum production process is relatively. Four, 4000 series aluminum plate is represented by 4A01 4000 series aluminum plate belongs to the series with higher silicon content. Fifth, the 5000 series represents the 5052.5005.5083.5A05 series. 6, 6000 series represents 6061 mainly contains two elements of magnesium and silicon, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-forged aluminum forging product. Seventy-eighth, eighty-eighth, 8000 series are more commonly used as 8011. Other series 00 series on behalf of 7075 mainly contain zinc. Eight, 8000 series is commonly used for 8011 belongs to other series. Nine, 9000 series are spare series. Flexible lift gate is a flexible soft curtain door, inside and outside the two curtains, curtains used between the aluminum beams connected with a vertically movable rail, the roof beams have levels not in the same straight line and hangar large plants in particular be applicable.
