Fluted Column Shaft
Polure fluted column shafts showcase vertical parallel concavity lines, catching ambient play of light and shadows across classical interiors and exterior porticos. Molded from high-density rigid polyurethane (150-220 kg/m³), these fluted shafts provide structural durability and high mechanical impact resistance without adding heavy dead load to floors. Their closed-cell structural composition ensures water absorption stays below 1%, making them rot-proof, mold-resistant, and non-swelling under humid conditions. Certified B2 for fire safety and stable from -100 °C / +80 °C, each shaft comes factory pre-primed with a white acrylic primer. Installation is completed with polyurethane assembly adhesive and countersunk screws.
Frequently Asked Questions
What characterizes a Polure fluted column shaft?
A fluted column shaft features vertical concave grooves cut into its circumference, adding rhythm and classical shadow depth.
Are Polure fluted column shafts load-bearing?
No, Polure fluted column shafts are non-load-bearing hollow decorative covers. Structural load must be supported by an internal steel column.
What density material is used in fluted column shafts?
They are molded from high-density rigid polyurethane (150-220 kg/m³), providing wood-like physical strength and impact resistance.
How are fluted column shafts attached?
Apply continuous lines of PU assembly adhesive on joining edges and contact surfaces, then fix with countersunk mechanical screws. Fill screw holes and sand prior to painting.
Can silicone adhesive be used to bond fluted column shafts?
No, silicone adhesive is strictly forbidden because it lacks structural bonding capability. Only polyurethane assembly adhesive paired with mechanical screws must be used.
