Differences between Prepainted Aluminum Coil and Prepainted Steel Coil

Difference Color Aluminum Coil Prepainted Steel Coil
Durability 25-40years 15years around

       Density: 2.71g/mm3 Lighter,

around one-third of Steel

Density: 7.85g/mm3
Strength & Rigidity In Middle Level, good enough for house construction Better
Appearance Much more smooth than steel smooth
Anti-thunder property Anti-thunder No anti-thunder property
Tile forming It has good welding property and keep physical property in low temperature It has cold shortness. In low temperature, it is easy to break.
Cost performance High cost performance. Light weight,water-proof, easy bending, good stereoscopic vision; Weight is three times of aluminum; middle level water-proof property;
Recovery Value High recovery Value, 70% of original value No recovery Value
Feature The meters per ton is three times longer than Steel; Comparative cheaper price
