Lightweight Polyurethane Handrail
Lightweight polyurethane handrails manufactured from high-density rigid polyurethane (150-220 kg/m³) combine ease of handling with robust mechanical impact strength. Perfect for staircases, balconies, and indoor/outdoor railings, these handrails maintain structural stability without warping, rotting, or splintering under heavy traffic. With closed-cell water absorption under 1%, they provide complete weather resistance across extreme temperature ranges (-100 °C / +80 °C). Pre-primed with a factory white acrylic technical primer, Polure lightweight handrails accept water-based, synthetic, or exterior UV-resistant paints. Installation requires clean mating channels, precision 45° miter cuts, continuous PU assembly adhesive, and mechanical screw attachment (silicone is strictly forbidden). Lightly sand with 180-220 grit paper prior to applying finish coats.
Frequently Asked Questions
What makes lightweight polyurethane handrails easy to install?
They offer high density (150-220 kg/m³) with significantly lower weight than timber or stone, allowing single-person mounting.
Will a lightweight polyurethane handrail rot outdoors?
No, water absorption is strictly under 1%, so it will never rot, swell, or splinter under rain or frost.
What adhesive should be used for lightweight handrails?
Mount using continuous PU assembly adhesive along with countersunk screws. Silicone is strictly forbidden.
