Weatherproof Baluster
Polure weatherproof balusters offer robust architectural detailing for exterior balustrades, terraces, and balcony systems. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these balusters deliver wood-like structural strength while remaining impervious to harsh environmental factors. Thanks to their closed-cell structure with water absorption under 1%, they will not rot, swell, split, or mold when exposed to heavy rain, ice, or high humidity. Engineered to perform reliably across extreme temperature ranges from -100 °C / +80 °C, they carry a B2 fire safety classification. Pre-treated at the factory with a white acrylic technical primer, they are ready for exterior painting. Installation requires clean surfaces, 45° miter cuts made with a fine-tooth saw, continuous PU assembly adhesive on all contact edges, and stainless steel screw anchoring. Fill screw heads and joints with facade filler, sand smooth with 180-220 grit, and finish with elastic UV-resistant exterior paint.
Frequently Asked Questions
What material is used to make the Polure weatherproof baluster?
The Polure weatherproof baluster is manufactured from high-density rigid polyurethane (150-220 kg/m³), offering high impact resistance, lightweight design, and B2 fire class safety.
Will the weatherproof baluster withstand rain, snow, and frost?
Yes. With water absorption under 1% and thermal endurance from -100 °C / +80 °C, the baluster will not rot, swell, or crack outdoors.
How is a weatherproof baluster properly installed on outdoor railings?
Apply continuous PU assembly adhesive on contact faces and secure mechanically with screws. Fill screw holes and joints with facade filler, sand with 180-220 grit, and paint.
Is silicone adhesive permitted for mounting the weatherproof baluster?
No, silicone is strictly forbidden because it lacks structural bonding power. Polyurethane assembly adhesive paired with mechanical screws must be used.
What coating should be applied to the weatherproof baluster?
After lightly sanding the factory acrylic primer with 180-220 grit sandpaper, paint with an elastic, UV-resistant exterior paint.
