aluminum plate is an important structural material for aircraft, and it is mainly used in fuselage, wing skin, oil tank etc. By using aluminum composite materials, the density of aircraft’s outer skin can be decreased by 5%-7%. As a result, the total weight can be reduced 10%, and therefore fuel efficiency increases. Moreover, 7% can be increased in stiffness of the material by using aluminum plate. Due to the superb corrosion resistance, fatigue resistance and damage tolerance of alunimium alloy, the inspection period can be extended and hence decreasing maintenance cost.
Depending on the state-of-the-art manufacturing technology, Signi aluminum plate is capable of providing various aluminum alloy products for aviation industries, such as wing skin, fuselage, stringer, chair skid, and augmented satellite launch vehicle etc.

|Sheet : Sheets are placed in wooden boxes on wooden skids with runners along the length of the sheet. They are wrapped in HDPE with hardboard on top and bottom of the stack. Hoop iron strapping runs along the length of the sheets. Silica gel packets are put in the boxes for moisture protection.(aluminum plate)|
