Exterior Decorative Column
Polure exterior decorative columns enhance building porticos, patio overhangs, and garden pavilions with timeless classical proportions. Molded from rigid high-density polyurethane (150-220 kg/m³), these columns feature a hollow interior designed to enclose structural steel posts while adding zero heavy structural weight to foundations. Closed-cell polymer engineering keeps water absorption under 1%, guaranteeing that the column casing will not swell, crack from freeze-thaw cycles (-100 °C / +80 °C), or rot under outdoor moisture. Supplied in standard diameters (20/30/40/50/60/80 cm) and 240 cm height, they are pre-primed with white factory primer. Assembly requires joining column halves or segments with continuous polyurethane assembly adhesive and mechanical screws. NEVER pour concrete inside. Sand joints smooth with 180-220 grit sandpaper and coat with two coats of UV-resistant exterior paint.
Frequently Asked Questions
Are Polure exterior decorative columns structural and load-bearing?
No, Polure exterior decorative columns are non-load-bearing casing elements. An internal steel core is required for load support.
Can concrete be poured inside an exterior decorative column?
No, concrete must NEVER be poured inside the hollow polyurethane casing as thermal expansion will fracture the outer shell.
What standard sizes do exterior decorative columns come in?
Exterior decorative columns feature standard diameters of 20, 30, 40, 50, 60, and 80 cm, and a standard height of 240 cm.
What adhesive should be applied to assemble column segments?
Polyurethane assembly adhesive must be applied on all joining edges. Silicone adhesive is strictly forbidden.
Why must exterior decorative columns be painted outdoors?
Outdoor columns must be painted with UV-resistant exterior facade paint to protect the factory primer from sun yellowing.
