Decorative Handrail Support
Polure decorative handrail supports combine architectural elegance with essential structural reinforcement for staircase and balcony balustrade systems. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these support elements provide wood-like mechanical strength while remaining light enough to prevent excess load on floor plates and handrails. The closed-cell material features water absorption below 1%, ensuring it will not rot, swell, or cultivate mold in damp interiors or exterior settings. Capable of enduring temperatures from -100 °C / +80 °C without cracking or distorting, each unit bears a B2 fire safety rating. Arriving pre-coated with a white acrylic technical primer, it is prepared for seamless topcoating. Installation requires clean surfaces, 45° miter cuts made with a fine-tooth saw, continuous PU assembly adhesive on contact joints, and mechanical countersunk screws. Fill joints and screw heads with facade filler, sand smooth with 180-220 grit, and finish with appropriate paint.
Frequently Asked Questions
What material is used in the Polure decorative handrail support?
The Polure decorative handrail support is manufactured from high-density rigid polyurethane (150-220 kg/m³), offering wood-like impact strength and B2 fire class safety.
Is the decorative handrail support suitable for exterior balustrades?
Yes. Featuring water absorption under 1% and thermal stability between -100 °C / +80 °C, it resists weather elements without rotting or swelling.
How is the decorative handrail support correctly installed?
Mount using continuous PU assembly adhesive on contact edges and mechanical countersunk screws. Fill screw holes and joints with filler, sand with 180-220 grit, and paint.
Can silicone be used for fixing the decorative handrail support?
No. Silicone is strictly forbidden as it lacks the required bonding strength. Only polyurethane assembly adhesive paired with screws should be used.
Does the decorative handrail support require priming prior to painting?
It comes with a factory white acrylic primer. Light sanding with 180-220 grit sandpaper is recommended before applying the final topcoat.
