Comparison
Hot-Rolled vs Cold-Formed Steel
Two ways of making steel sections, suited to different loads.
| Specification | Hot-Rolled | Cold-Formed |
|---|---|---|
| Formed | At high temperature | From coil at room temperature |
| Strength-to-weight | Heavier loads | Efficient for light framing |
| Use in solar | Main members, heavy load | Purlins, rails, light framing |
Frequently asked questions
- Which is better for solar structures?
- Both are used — hot-rolled for main load-bearing members, cold-formed for efficient light framing like purlins and rails.
