Column Cap Design
Polure column cap designs deliver refined architectural proportions and crisp relief detailing for interior columns, porch pillars, and facade colonnades. Molded from high-density rigid polyurethane (150-220 kg/m³), these architectural designs match timber mechanical strength while remaining lightweight overhead. Their closed-cell structure keeps water absorption under 1%, ensuring complete resistance to rot, swelling, mold, and weather exposure outdoors. Rated B2 for fire safety and stable from -100 °C / +80 °C, every column cap design section is pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive to contact faces, securing with mechanical screws, filling fastener holes with facade filler, sanding smooth with 180-220 grit, and painting with topcoat paint.
Frequently Asked Questions
What material is used for Polure column cap designs?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are column cap designs load-bearing?
No, Polure column cap designs are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install column cap designs?
Apply continuous PU assembly adhesive on contact edges, secure with mechanical screws, fill screw holes with filler, sand, and paint.
Is silicone allowed for mounting column cap designs?
No, silicone is strictly forbidden as it lacks long-term bonding strength. Always use polyurethane assembly adhesive with mechanical screws.
