Architrave Column Capital
Polure architrave column capital provides an ornate transitional crown connecting vertical columns to horizontal architraves, beams, and ceiling entablatures. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this decorative capital offers wood-like mechanical strength and sharp motif definition while remaining lightweight to eliminate top-heavy structural strain. Featuring a closed-cell composition with water absorption under 1%, it will not rot, mold, swell, or crack in extreme weather 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.
