Steel vs Aluminum frames: which is better?
Data Insight: According to structural engineering standards (EN 1993), hot-dip galvanizing extends steel lifespan by over 50 years in mild environments.
| Material | Pros | Cons |
|---|---|---|
| Galvanized Steel | Max Strength, Cost | Heavy |
| Aluminum T6061 | Lightweight, No Rust | Higher Cost |
Common Mistakes
- Buying powder-coated steel that isn't hot-dip galvanized first
- Using low-grade PVC that degrades in UV
- Skipping the frame rust treatment
