Round Column Capital
Polure round column capitals add classical elegance and refined architectural detailing to interior and exterior column installations. Crafted from high-density rigid polyurethane (150-220 kg/m³), these capitals deliver exceptional impact resistance without adding heavy structural load to walls or pillars. The closed-cell material features water absorption under 1%, ensuring that the capitals will not rot, swell, mold, or attract insects in humid areas or exterior environments. Formulated to endure temperatures from -100 °C / +80 °C without shrinking or warping, they feature a B2 fire safety rating. Arriving pre-primed with white acrylic technical primer, they require a dual-mounting installation using polyurethane assembly adhesive and countersunk mechanical screws. Complete by painting with quality topcoat.
Frequently Asked Questions
Are Polure round column capitals suitable for load-bearing applications?
No, Polure round column capitals are purely decorative and non-load-bearing. Any structural load must be supported by an internal structural post or steel core.
What density material is used in round column capitals?
Polure round column capitals are produced from high-density rigid polyurethane with a density of 150-220 kg/m³ (production target ~160 kg/m³), providing wood-like strength and high impact resistance.
How are round column capitals attached during installation?
Installation requires applying a continuous line of PU assembly adhesive on contact edges and securing with countersunk screws. Screw holes are filled with acrylic filler and sanded smooth before painting.
Can round column capitals be installed on exterior porches?
Yes, their water absorption is below 1% and they withstand temperature range of -100 °C / +80 °C. They must be painted with UV-resistant exterior paint after installation.
Can silicone be used to glue round column capitals?
No, silicone is strictly forbidden because it does not provide sufficient bond strength. Only polyurethane assembly adhesive paired with mechanical screws must be used.
