Architectural PU Corbel
Polure architectural PU corbels serve as refined decorative accents for entryways, roof overhangs, interior archways, and mantelpieces. Cast in high-density rigid polyurethane (150-220 kg/m³), these architectural brackets provide high mechanical strength and impact resistance with minimal structural weight. Thanks to a closed-cell polymer structure with water absorption under 1%, these corbels will not rot, swell, or cultivate mold in high-humidity areas like bathrooms or exposed outdoor facades. Operational across temperature extremes from -100 °C / +80 °C and rated B2 for fire safety, each corbel carries a factory-applied white acrylic primer. Installation is executed by applying continuous polyurethane assembly adhesive on rear surfaces and anchoring with mechanical screws. Screw heads are countersunk, filled with putty, sanded smooth, and painted.
Frequently Asked Questions
What density material is used for Polure architectural PU corbels?
They are molded from high-density rigid polyurethane (150-220 kg/m³), providing wood-like impact resistance without structural weight.
Are Polure architectural PU corbels load-bearing?
No, Polure architectural PU corbels are decorative non-load-bearing architectural elements.
Can architectural PU corbels be installed on exterior building facades?
Yes. With water absorption under 1%, they withstand weather conditions from -100 °C / +80 °C without rotting or warping when topcoated with UV paint.
How are architectural PU corbels attached to walls?
Apply continuous polyurethane assembly adhesive to contact faces and secure with mechanical screws. Fill screw holes with filler, sand, and paint. Silicone is forbidden.
What painting instructions apply to architectural PU corbels?
Corbels come factory-primed with white acrylic primer. Indoor applications use water-based paints; exterior applications require elastic UV-resistant facade paint.
