Metal Pergola & Art Trellis: Design & Procurement Guide
A metal pergola (art trellis, 廊架) defines outdoor spaces — shade structures, entrance features and landscape landmarks. This guide covers material selection and specification.
1. Steel vs Aluminum
| Material | Strength | Corrosion | Typical Use |
|---|---|---|---|
| Galvanized steel | High (large spans) | Good with coating | Main structure |
| Stainless steel (304/316) | High + premium look | Excellent | Landmark projects |
| Aluminum | Moderate | Excellent | Lightweight canopies |
2. Finishes
Steel: hot-dip galvanizing + outdoor powder coating. Aluminum: anodizing or powder coating. For coastal or industrial atmospheres, upgrade to stainless or marine coating. Colour should be specified from the architect's palette — ASPER commonly supplies deep bronze, graphite and custom RAL colours.
3. Design & Engineering
- Wind load and snow load calculations per local code
- Member sizing for canopy, lighting and climber-plant loads
- Connection details and anchor/foundation design
- Drainage and anti-slip details
