Steel Wind Column KFZ-1: HN500×200, Q355B, 3,385 kg

Wind columns (gable posts) are vertical steel members placed at building gable ends to resist horizontal wind loads and transfer them to foundation. Below is member KFZ-1 from an actual fabrication drawing.

Construction Details

The column consists of main H-section plus stiffeners and connection plates:

· Main shaft: HN500×200×10×16, Q355B

· Top end plate: PL16×490, 1 pc

· Base plate: PL20×490, 1 pc

· Web stiffeners: PL10×495, 2 pcs at critical sections

· Shear tabs: PL10×175, 4 pcs

· Base connection plates: ZP series, multiple sizes

· Gusset plates: Z-50, Z-78 etc.

Stiffeners are positioned at load transfer points — where girts, braces or crane brackets connect.

Why Wind Column Matters

1. Resists gable wind load — transfers horizontal wind pressure on gable wall to foundation

2. Supports gable wall cladding — spaced 6–9 m apart, supports wall girts and panels

3. Stabilizes building longitudinally — works with roof bracing to prevent racking

4. Q355B steel — higher yield strength, lighter section for same wind load​

Typical Applications

1. Single-story industrial plants — standard use at both gable ends of factory buildings

2. Warehouse & logistics centers — long gable walls need intermediate wind columns

3. Steel structure workshops — especially in high-wind or seismic regions

4. Aircraft hangars & large sheds — large gable openings require heavy wind columns

5. Agricultural buildings — livestock sheds and greenhouses in exposed locations

Installation Notes

· Base: bolted to foundation anchor bolts, grouted after alignment

· Top: slotted connection to roof beam allows vertical movement while resisting lateral load

· Girts bolted to column tabs; no welding on site
