Exterior Architectural Corbel
Polure exterior architectural corbels bring classical ornamental support aesthetics beneath roof eaves, balconies, window sills, and entrance overhangs. Molded from high-density rigid polyurethane (150-220 kg/m³), these exterior corbels provide timber-like structural rigidity while resisting severe weather, including hail impacts without denting. Featuring a closed-cell physical matrix with water absorption under 1%, they will not absorb moisture, swell, rot, or freeze-thaw crack. Tested to withstand temperature ranges from -100 °C / +80 °C with B2 flame retardancy, every corbel is factory pre-coated in white acrylic primer. Installation requires clean masonry or wall substrates, continuous polyurethane assembly adhesive applied to mounting contact faces, and compulsory mechanical fixings with countersunk screws; silicone bonding is strictly prohibited. Joint seams and countersunk screw locations are filled with exterior facade filler, sanded smooth with 180-220 grit paper, and finished with UV-resistant elastic facade paint.
Frequently Asked Questions
What material is Polure exterior architectural corbel made from?
It is molded from high-density rigid polyurethane (150-220 kg/m³), providing timber-like strength, hail impact resistance, and B2 fire safety rating.
Are exterior architectural corbels load-bearing?
No. Polure corbels are decorative architectural elements; structural loads must be supported by internal steel or building framework.
How is an exterior corbel properly installed on facades?
Apply continuous PU assembly adhesive to contact backs and secure with countersunk screws. Silicone is forbidden. Fill joints with facade putty.
What paint finish is required for outdoor corbels?
Exterior installations require elastic, UV-resistant facade paint applied in matching primer systems to prevent fading.
