- **Caution**: 

### Q: What materials are support arms/chocks typically made from?
**A**: Our support arms/chocks are manufactured from high-strength carbon steel or alloy steel to withstand the heavy loads and stresses encountered during coil unwinding processes in industrial settings.

### Q: How do support arms/chocks improve decoiler system performance?
**A**: They provide critical lateral support and stabilization to coils/rolls during unwinding, preventing wobble, misalignment, and material damage, which ensures smoother operation and reduces downtime in machinery manufacturing.

### Q: What are the main components of a support arm/chock assembly?
**A**: A complete assembly includes an adjustment mechanism for precise positioning, contact pads/shoes for coil interface, mounting brackets for secure attachment, and a robust support arm frame for structural integrity.
