Column Capital Head
Polure architectural column capital heads crown interior and exterior decorative columns with classical sculptured proportions. Precision-molded in high-density rigid polyurethane (150-220 kg/m³), these ornamental capital heads reproduce classical Doric, Ionic, and Corinthian carving details without heavy masonry weight. Designed as hollow decorative crown shells, they are non-load-bearing and must never be filled with concrete; structural loads require an internal steel support column. Featuring a closed-cell polymer matrix with water absorption under 1%, they offer complete immunity to rot, mold, and atmospheric weathering across temperatures from -100 °C / +80 °C with B2 fire safety. Every capital head comes factory-precoated with a white acrylic primer. Installation is executed by securing over column shafts with continuous polyurethane assembly adhesive paired with mechanical countersunk screws.
Frequently Asked Questions
Are Polure column capital heads load-bearing?
No. They are hollow decorative capital heads and strictly non-load-bearing. An internal steel column profile must support structural loads.
Can concrete be poured inside Polure column capital heads?
No, pouring concrete inside polyurethane column capital heads is strictly forbidden as it will cause material deformation.
What material density is used for Polure column capital heads?
They are molded from high-density rigid polyurethane (150-220 kg/m³), delivering stone-like mechanical durability at a lightweight handle.
How are column capital heads mounted during installation?
Apply continuous polyurethane assembly adhesive to contact joints and anchor with mechanical screws. Silicone is forbidden.
What paint finish should be applied to column capital heads?
Capital heads come factory-primed with white acrylic primer. Use acrylic interior paint indoors, or elastic UV-resistant facade paint outdoors.
