**Recommended Minimum Frame Sizes for Columns**
| Column DN | Tube Size NB (mm) | Min Structure Depth × Width (mm × mm) | |———–|——————–|——————————————-| | 80 | 25 | 500 × 500 | | 100 | 25 | 500 × 500 | | 150 | 25, 30 | 600 × 600 | | 225 | 30 | 800 × 800 | | 300 | 30 | 800 × 800 | | 400 | 30 | 1000 × 1000 | | 450 | 30, 40 | 1000 × 1000 | | 600 | 40, 50 | 1200 × 1200 |
**Design Notes & Guidelines**
– The frame must provide lateral rigidity and resist sway or vibration
– The tube size selected must match or exceed the NB indicated
– The frame should integrate with base fittings and bracing members
– These dimensions serve as minimum recommendations; field conditions or heavier loads may demand larger frames
– The frame must also accommodate guide supports and be braced to adjacent rigid structures for lateral stability
