Dry Steel Coil Roll Forming Material Guide: Non-Oiled Steel Properties
Dry Steel Coil Roll Forming Material
1. Overview of Dry Steel Coil in Roll Forming
Dry steel coil refers to steel supplied without any oil coating, unlike pickled & oiled or standard oiled steel. It is typically used where a clean surface is required or where additional processes such as painting, coating, or galvanizing will follow.
In roll forming, dry steel is commonly used for precision profiles, painted products, automotive components, and applications requiring a clean surface finish.
Compared to oil coated steel, dry steel offers better surface cleanliness and reduced contamination, but requires more controlled storage to prevent rust.
2. Material Composition & Structure
Dry steel coil typically consists of:
- Steel base (cold rolled or hot rolled)
- Clean surface (no oil layer)
- Optional surface treatment (e.g., pickled or cleaned)
Key Feature
- No oil protection
- Clean surface ready for further processing

13. Comparison with Other Materials
Dry Steel vs Oil Coated Steel
- Dry = clean surface
- Oil coated = rust protection
Dry Steel vs Galvanized Steel
- Dry = no protection
- Galvanized = corrosion resistant
Dry Steel vs PPGI
- Dry = base material
- PPGI = finished coated product
