Exterior Polyurethane Pillar
Polure exterior polyurethane pillar provides weatherproof elegance for residential entryways, garden verandas, and commercial building fronts. Fabricated from high-density rigid polyurethane (150-220 kg/m³), this hollow pillar matches wood mechanical strength while avoiding heavy structural strain on floors. Closed-cell geometry maintains water absorption under 1%, guaranteeing zero rotting, swelling, mold growth, or insect infestation in damp or outdoor environments. Designed to withstand temperature extremes from -100 °C / +80 °C, it meets B2 fire safety standards for flame resistance. Factory pre-primed with white acrylic technical primer, mounting requires continuous PU assembly adhesive at contact edges along with mechanical countersunk screws. Fill joint lines with acrylic putty, sand with 180-220 grit paper, and coat with quality topcoat paint.
