Column Head Capital
Polure column head capital provides a classical decorative top finish for interior columns, entrance pillars, and architectural porticos. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this capital element offers wood-like mechanical durability while remaining lightweight to prevent top-heavy load 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 crown, it fits over internal structural posts. Installation requires continuous polyurethane assembly adhesive along contact faces, paired with mechanical countersunk screws. Fill seams with acrylic putty, sand smooth with 180-220 grit paper, and finish with quality paint.
