Exterior Fluted Column
Polure exterior fluted column provides timeless neoclassical elegance and vertical shadow lines for grand porch entrances, outdoor porticos, and garden pergolas. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this fluted architectural column delivers wood-like mechanical durability while remaining lightweight to prevent load stress on building foundations. Featuring a closed-cell composition with water absorption under 1%, it will not rot, mold, swell, or crack during frost-thaw cycles or 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 seamlessly encases internal structural steel posts. Installation requires continuous polyurethane assembly adhesive on joining seams, paired with mechanical countersunk screws. Fill seams with acrylic putty, sand smooth with 180-220 grit paper, and finish with UV-resistant paint.
