Spiral Fluted Pillar
Polure spiral fluted pillar brings dramatic classical elegance and twisted vertical texture to entrances, rotundas, and living halls. Molded from high-density rigid polyurethane (150-220 kg/m³), this decorative column shaft combines wood-like mechanical toughness with a lightweight structure. Designed as a hollow, NON-LOAD-BEARING decorative element, structural loads must be carried by an internal steel column profile; pouring concrete inside is strictly forbidden. Its closed-cell physical core maintains water absorption below 1%, ensuring it will not rot, swell, or mold in damp areas or outdoors. Fire-rated to class B2 and thermally stable from -100 °C / +80 °C, it arrives pre-coated with factory white acrylic primer. Installation requires clean, dry surfaces. Apply continuous polyurethane assembly adhesive on joint edges; silicone sealant is strictly prohibited. Screw attachment is mandatory for permanent security; countersink screw heads, fill with acrylic putty, sand smooth with 180-220 grit paper, and finish with interior water-based or exterior UV-resistant facade paints.
Frequently Asked Questions
Can Polure spiral fluted pillar support structural building loads?
No. It is hollow and strictly non-load-bearing. Any structural load must be supported by an internal steel profile.
Is it permissible to pour concrete inside a spiral fluted pillar?
No. Concrete must NEVER be poured inside polyurethane pillars as expansion and moisture will cause damage.
What material is the spiral fluted pillar made from?
It is molded from high-density rigid polyurethane (150-220 kg/m³), offering high mechanical strength and B2 fire class safety.
How is the spiral fluted pillar installed and painted?
Mount with PU assembly adhesive and screws (silicone is forbidden). Fill screw holes, sand with 180-220 grit, and apply UV exterior paint for outdoor use.
