Differences between Prepainted Aluminum Coil and Prepainted Steel Coil

DifferenceColor Aluminum CoilPrepainted Steel Coil
Durability25-40years15years around
Weight       Density: 2.71g/mm3 Lighter,

around one-third of Steel

Density: 7.85g/mm3
Strength & RigidityIn Middle Level, good enough for house constructionBetter
AppearanceMuch more smooth than steelsmooth
Anti-thunder propertyAnti-thunderNo anti-thunder property
Tile formingIt has good welding property and keep physical property in low temperatureIt has cold shortness. In low temperature, it is easy to break.
Cost performanceHigh cost performance. Light weight,water-proof, easy bending, good stereoscopic vision;Weight is three times of aluminum; middle level water-proof property;
Recovery ValueHigh recovery Value, 70% of original valueNo recovery Value
FeatureThe meters per ton is three times longer than Steel;Comparative cheaper price
