Aluminum Surface Finishes & Protection
| Surface Finishes | Description | Features | Protection |
| Mill Finish | The natural finish of aluminum after rolling, without additional processing. | Non-uniform reflectivity, and a slightly rough surface with a matte or dull metallic sheen. | Paper interleaved, PE/PVC filming (if specified) |
| Anodizing | An electrochemical process that thickens the natural oxide layer on the aluminum surface. | Enhances corrosion resistance, hardness, and allows for coloring. | |
| Powder Coating | A dry finishing process where a powder is electrostatically applied and cured under heat. | Durable, colorful, and resistant to chipping, scratching, and fading. | |
| Brushed Finish | The surface is mechanically polished to create a uniform satin texture. | Decorative, with a linear grain and reduced reflectivity. | |
| Mirror Finish (Polishing) | The aluminum sheet is polished to a highly reflective, mirror-like surface. | Smooth, glossy, and highly reflective. | |
| Embossing | The aluminum sheet is passed through rollers that emboss a raised or patterned texture on the surface. | Adds visual appeal and increases strength and rigidity. |
Packaging of Aluminum Coil and Strip
| Protective Wrapping | Edge Protection and Cushioning | Securing and Palletizing |
| Aluminum Coils and Strips are carefully wrapped with waterproof materials, such as plastic film or kraft paper, to shield against moisture, dust, and contamination in transit. | Edge protectors and padding are applied around the coils to prevent physical damage, dents, or scratches during handling and shipping. | The wrapped coils are securely strapped to wooden or metal pallets using durable steel or plastic bands, ensuring stability and safety in transit. |
