| Alternative | Pros | Cons in Hot Conditions | |-------------|------|--------------------------| | HeliBar (helical bars) | Same material as ATIR, round profile | Less surface bearing than flat strap | | Mechanical stitch plates (steel) | High strength | Needs anchor bolts; thermal expansion mismatch | | High‑temp epoxy + carbon fiber | Aesthetic, adds flexural strength | Epoxy loses modulus above 60°C; expensive | | Stitching with copper pins | Heat conduction | Corrosion; soft material |
