Polyurethane Spiral Column Shaft Model

The P5830C is a spiral-shafted architectural element designed to bring dynamic movement and visual depth to classical architectural projects. The helical twists on its surface enhance the play of light and shadow, adding an aesthetic volume to any space. It can be confidently used in both interior designs and exterior facades, either as a decorative cladding for structural columns or as a standalone pillar.

Crafted from high-density rigid polyurethane, this structural material features a density of 150-220 kg/m³. It offers a surface hardness comparable to wood while remaining exceptionally lightweight compared to traditional alternatives like marble, stone, or concrete. This lightweight design prevents adding static load to buildings and ensures effortless installation. Thanks to its closed-cell structure, its water absorption rate is below one percent, largely preventing rotting, swelling, or insect infestation in humid climates or outdoor conditions.

The spiral grooves break the monotony of vertical lines, introducing a fluid rhythm to spaces. Delivered factory-primed in white, the surface is ready for the final coat of paint. Either water-based or synthetic paints can be applied. While the factory primer facilitates paint adhesion, applying an additional primer is entirely up to the user's preference and the technical requirements of the chosen paint, due to paint manufacturers' warranty conditions for their own priming systems.

This decorative shaft has had its dimensional stability tested between -20 °C and +70 °C, maintaining its dimensional stability. For exterior applications, it must be protected with UV-resistant exterior paints to prevent the yellowing effect of sunlight. The material has fire class B2 (DIN 4102-1).

During installation, Polure Polfix adhesive should be applied to clean, leveled surfaces, followed by mechanical fastening with screws. Once joints and screw heads are filled with a suitable filler and smoothed with 180-220 grit sandpaper, painting can begin. Unlike plaster, which crumbles, or wood, which cracks, this structural element offers a long-lasting, maintenance-free decorative alternative.
