Fluted Pillar Shaft
Polure fluted pillar shaft brings classical vertical groove detailing to interior columns and exterior architectural entryways. Constructed from high-density rigid polyurethane (150-220 kg/m³), this hollow decorative shaft delivers high mechanical strength while maintaining a lightweight profile for straightforward handling. The closed-cell structure keeps water absorption under 1%, ensuring complete immunity to rot, mold, swelling, and insect attack. Heat and frost resistant between -100 °C / +80 °C, the shaft holds a B2 fire safety rating for self-extinguishing safety. Pre-primed with factory white acrylic technical primer, installation involves placing continuous PU assembly adhesive on joining ends and securing with mechanical countersunk screws. Seal seam lines with acrylic putty, sand with 180-220 grit paper, and paint with standard topcoats.
