- **Caution**: 

### Q: What are the main material options for column castings/weldments?
**A**: Our column castings/weldments are available in three primary materials: cast iron for vibration damping and stability, steel weldment for high strength and customization, and granite composite for exceptional thermal stability and precision in demanding applications.

### Q: What components are included in the standard BOM for these columns?
**A**: The standard bill of materials includes: Base Plate for foundation mounting, Vertical Frame as the main structural element, Guide Rail Mounting Surfaces for precision alignment, Internal Ribbing for enhanced rigidity, and Top Plate for machine component attachment.

### Q: How do I choose between cast iron and steel weldment columns?
**A**: Choose cast iron columns when vibration damping, thermal stability, and mass are critical for precision machining applications. Select steel weldment columns when you need higher strength-to-weight ratio, customization flexibility, or specific dimensional requirements not easily achieved with casting.

## 6. Manufacturing Compliance
- ISO 11970:2016 (SPECIFICATION FOR STEEL CASTINGS FOR PRESSURE PURPOSES)
