Ⅲ.Appearance Quality
1. Free of grease (grease＜10mg/m2);
2. No tarnishing, no stains, no rolling marks, no oxidation, noaluminum powder and other defects;
3. Smooth coil surface
Ⅳ.Package, transportation, and storage
Package is as customers’ requirements, usually 3 vacuumized layersinner and one layer of craft paper outside which can completely resist humidityand oxidation ; metal pallet.
Storage Tips:
1. Do not clash or throw aluminum coil when carried;
2. The aluminum coil should be drily stored away from heat resource,oil and chemicals. Outdoor storage is prohibited;
3. To use aluminum coil as early as possible;
4. Do not open those aluminum coils you won’t use shortly. And sealthe opened package and put a desiccant in the package to resist the humidityand oxidation.
