The P5820B50 polyurethane plain half column shaft is an architectural element designed to aesthetically encase concrete or steel columns or to create a semi-recessed column effect on flat walls. Featuring a depth of 100 mm, a width of 200 mm, and a height of 2400 mm, its semi-circular form easily adapts around existing structural supports.
Manufactured from high-density rigid polyurethane, the product features a density of 150-220 kg/m³ (production target ~160 kg/m³), offering a balance of wood-like durability and lightweight handling. Thanks to its closed-cell structure, the water absorption rate remains under 1%, preventing rotting, mold formation, or warping in humid conditions. With a wide operational temperature range from -100 °C / +80 °C, it maintains its structural form in both interior and exterior facade applications.
The visual design presents a smooth, unpatterned shaft surface. Its clean profile integrates seamlessly across various architectural concepts, from modern spaces to classic interiors. The factory-applied primer coat provides a smooth foundation for paint. It can be painted with water-based or synthetic paints to match any interior or exterior color scheme.
In addition to structural column cladding, it is widely used to create decorative vertical accents in building entrances, hotel lobbies, event halls, wide corridors, and residential facades. Combining two half column shafts face-to-face forms a full round column with a 200 mm diameter. When paired with matching capital and base profiles, it converts into a complete column system with precise architectural proportions.
Its lightweight construction simplifies handling and alignment during installation. The component is mounted using polyurethane (PU) assembly adhesive and supported with mechanical fixings. Once joints are filled with sealant and sanded smooth with 180-220 grit sandpaper, painting can proceed. Compared to heavy concrete or cast stone alternatives, it adds no extra dead load to the structure, carries no risk of cracking, and maintains its appearance over time.
- The polyurethane plain half column shaft offers versatile applications in architectural design
- Indoors, it is frequently specified to conceal bare concrete or steel columns in living rooms, foyers, hotel receptions, restaurants, and lounges
- It can also be placed at regular intervals along flat walls to add spatial depth and visual rhythm
- For exterior applications, it is ideal for entrance porticos, villa facades, and terrace column wraps when finished with UV-resistant paint
- It can be completed with matching capitals and bases or installed individually for a clean, minimal look
- The mounting surface must be clean, dry, and free of dust
- Apply polyurethane (PU) assembly adhesive along the contact edges and joint points of the half column shaft
- Silicone adhesives should not be used as they lack proper bonding strength
- Position the piece against the wall or column, level it, and secure it with mechanical fasteners (screws/anchors) until cured
- Fill screw recesses and joints with flexible filler, then sand smooth with 180-220 grit sandpaper after drying
- Although factory-primed, follow the paint manufacturer's guidelines before applying at least two coats of water-based or synthetic paint
- Maintenance is minimal thanks to the smooth, closed-cell surface structure
- Dust and surface dirt can be cleaned using a damp cloth
- Avoid harsh acidic cleaners, abrasive chemicals, or stiff brushes that could damage the paint layer
- For exterior applications, periodic checks of the topcoat paint and repainting when necessary will preserve the product's original finish
Can the polyurethane plain half column shaft be used outdoors?
Yes, with a water absorption rate under 1% and continuous resistance between -100 °C / +80 °C, the product is suitable for exterior use. Applying an exterior-grade, UV-resistant paint is required to protect it against sun exposure.
How is the column shaft installed and painted?
Installation is completed using polyurethane (PU) assembly adhesive supported by mechanical screw fixings. Silicone must not be used. Joint lines and screw heads are filled with putty and sanded smooth with 180-220 grit sandpaper. The factory primer surface can be painted using water-based or synthetic paints.
Does this product serve as a load-bearing column?
No, decorative polyurethane products do not possess structural load-bearing capacity. However, they provide an ideal cladding solution to encase existing structural steel or concrete columns for a decorative finish.
What are its advantages compared to plaster or concrete columns?
Include the product weight and fixing loads when assessing the substrate and supporting structure. Unlike plaster or concrete, it does not crack, chip, or crumble from moisture or minor impacts, making transportation and mounting far more practical.
Can two half columns be combined to form a full round column?
Yes, two half column shafts measuring 100 mm in depth and 200 mm in width can be joined face-to-face. Once the joints are filled and sanded, a continuous, full round column with a 200 mm diameter is achieved.
