| Surface Type | Description | Typical Applications |
| Mill Finish | Raw hot-rolled surface, slightly rough with natural oxide scale | Suitable for further processing, welding, or painting |
| Pickled & Oiled | Acid-cleaned to remove scale, then coated with protective oil | Long-term storage and transport, corrosion protection |
| Shot Blasted | Surface cleaned and roughened using sand or steel shot | Pre-treatment for coatings, improves paint adhesion, anti-corrosion prep |
| Special Coating / Painted | Customized industrial coatings or paint applied | Outdoor, chemical, or highly corrosive environments |
1. Raw Material Preparation
