Common Specifications
- Profiles: Typically available in C-channel or U-channel shapes (e.g., 38mm x 38mm or 41mm x 41mm).
- Lengths: Standard lengths include 3.2m, 3.5m, and 6.0m.
- Design: Usually slotted to allow for adjustable mounting with threaded rods, bolts, or specialized clips.
- Material: Made from galvanized steel (often grade Q235), providing a balance of strength and cost-effectiveness compared to aluminum.
Key Considerations
- Durability: While 1mm is common for lightweight setups, heavier industrial projects often require 2.0mm to 2.5mm thickness for higher wind and snow load resistance.
- Coating: Look for standard industry coatings like Z275 for standard outdoor use, as it provides the bare minimum for a long-lasting solar plant life.
- Installation: These rails are often compatible with screwless clip systems or standard T-nut bolts for rapid deployment.
