Polyurethane plain half column body P5820B50 is a high-density architectural cladding element designed to encapsulate existing structural posts or create clean vertical features on interior and exterior walls. Featuring a semi-circular inner cavity with a width of 200 mm, a depth of 100 mm, and an overall height of 2400 mm, this decorative column shell provides a smooth surface that seamlessly transforms ordinary structural supports into refined architectural focal points.
Manufactured from high-density rigid polyurethane with a density of 150-220 kg/m³, this profile offers wood-like structural firmness while remaining lightweight for simple installation. The closed-cell polymer composition guarantees a water absorption rate under 1%, preventing rot, swelling, or mold growth even in high-humidity settings. Furthermore, the robust material has been tested for dimensional stability between -20 °C and +70 °C without cracking or dimensional warping.
The aesthetic appeal of this half-column shell lies in its minimalist, unadorned profile. Its smooth geometric contour harmonizes effortlessly with contemporary minimalist designs as well as classical facade layouts. Delivered with a factory-applied white primer coat, the smooth surface provides an excellent bond for topcoat application, allowing customized color integration with surrounding walls, capitals, or bases.
This versatile half-column cladding is widely specified in residential and commercial architecture. In interior spaces, it functions as a decorative wall pilaster or conceals structural steel and concrete pillars in living rooms, hotel foyers, and reception areas. For exterior applications, when finished with UV-resistant paint, it elevates building entrances, porticos, and covered patio columns.
Installation is efficient and manageable compared to heavy concrete or plaster alternatives. The lightweight half-shell is positioned using high-strength polyurethane (PU) mounting adhesive supplemented by mechanical screw anchoring for safety. Joints and screw heads are easily smoothed using standard filler and 180-220 grit sandpaper prior to painting, achieving a continuous monolithic look.
- The plain polyurethane half column body is designed for versatile application across interior and exterior architecture
- It is primarily specified to enclose concrete, steel, or timber support posts, converting plain structural elements into sleek decorative pillars
- In residential interiors such as living rooms, grand hallways, and entrance lobbies, these half columns function as decorative wall pilasters that add depth and classical proportion
- Commercial projects, including hotel foyers, restaurants, event halls, and retail spaces, utilize their high impact resistance and refined finish
- When applied to exterior facades, garden porticos, or covered entrance gates, the profile retains its resistance to moisture, provided it is finished with an appropriate UV-resistant exterior coating
- Ensure the application surface and column inner channel are clean, dry, and dust-free
- Apply a continuous bead of polyurethane (PU) mounting adhesive along the rear contact edges of the column shell
- Position the profile firmly against the wall or around the structural post
- For permanent structural safety, reinforce the installation using mechanical screws anchored into wall plugs at regular intervals along the length
- Fill all screw countersinks and joint connections with acrylic or PU filler
- Once fully set, sand the filled seams smooth using 180 to 220 grit sandpaper
- Note that while the factory primer prepares the surface, paint manufacturers often require their own dedicated primers to uphold paint warranties; applying an additional primer coat remains optional at the customer's discretion
- Finish by applying two topcoats of water-based or synthetic paint
- Maintaining the smooth polyurethane column body is simple due to its dense, non-porous surface
- Regular maintenance involves wiping down the column with a soft cloth or sponge dampened with warm water and a mild household detergent
- Avoid using abrasive sponges, harsh scouring powders, or strong solvent cleaners
- For outdoor installations, inspect the painted topcoat periodically and reapply UV-resistant exterior paint as needed to ensure long-term surface protection
Can this half column profile be installed on exterior building facades?
Assess water and moisture exposure using the product technical data, surface finish and installation details. For outdoor application, the surface must be finished with a high-quality UV-resistant exterior paint to protect against long-term sunlight exposure.
How is the column body installed around an existing structural pillar?
Two half-column shells can be joined together around an existing pillar, or a single shell can be mounted flat against a wall. Bonding is performed using polyurethane (PU) mounting adhesive combined with mechanical screw fastenings for safety.
How durable is this polyurethane column body compared to traditional plaster?
Polyurethane offers superior impact resistance and will not chip, crack, or crumble like gypsum plaster. With a high density of 150-220 kg/m³, it provides structural firmness while remaining light enough for easy single-person handling.
Is an additional primer coat required before painting?
The product comes factory pre-primed to facilitate paint adhesion. However, because paint manufacturers typically require their own specific primers to guarantee coating performance, applying an extra primer coat is optional and left to the installer's judgment.
What are the exact dimensions and inner clearance of this half column?
The shell measures 200 mm in total width, 100 mm in depth, and 2400 mm in height, featuring a semi-circular cavity engineered to enclose vertical supports up to 200 mm in diameter when two units are paired.
