Fluted Column Shaft
Polure fluted column shaft adds classical vertical lines and light-and-shadow depth to architectural interior pillars and building facade columns. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this grooved column shaft offers wood-like mechanical durability while remaining lightweight to eliminate structural strain. Featuring a closed-cell composition with water absorption under 1%, it will not rot, mold, swell, or split across extreme temperatures from -100 °C / +80 °C. Rated Class B2 for self-extinguishing fire safety, it arrives pre-coated with factory white acrylic technical primer. Designed as a hollow decorative cladding shell, it encases internal structural steel cores. Installation requires continuous polyurethane assembly adhesive along contact edges and joining seams, secured with countersunk screws. Fill seams with acrylic putty, sand smooth with 180-220 grit paper, and paint.
Frequently Asked Questions
What material is used for Polure fluted column shaft?
Polure fluted column shaft is manufactured from high-density rigid polyurethane (150-220 kg/m³), ensuring high impact resistance and Class B2 fire safety.
Is Polure fluted column shaft suitable for outdoor facade installation?
Yes. With water absorption under 1% and thermal stability from -100 °C / +80 °C, it is fully suitable for outdoor facade use when painted with UV paint.
How is Polure fluted column shaft installed?
Installation requires continuous polyurethane assembly adhesive along joining edges and mechanical countersunk screws. Silicone is strictly forbidden.
Are Polure fluted column shafts load-bearing?
No, they are hollow decorative cladding covers. Structural loads must be carried by an internal steel core.
