Introduce an elegant architectural transition to your interior or exterior spaces with this premium round arch frame. Designed to elevate standard doorways, hallways, and window heads, this decorative element brings classical symmetry and structural depth to any project. Its clean, stepped concentric profile acts as a sophisticated focal point, seamlessly bridging the gap between historical grandeur and modern minimalism.
Measuring 170x1750x971 mm, this arch is engineered from high-density rigid polymer with a density of 150-220 kg/m³ (production target ~160 kg/m³). This advanced material delivers the structural hardness and crisp detail of traditional timber but without the associated weight or susceptibility to environmental degradation. Featuring a closed-cell structure with water absorption under 1%, it remains completely unaffected by humidity, rot, or insect damage, maintaining its precise dimensional stability across temperatures ranging from -100 °C / +80 °C.
Visually, the design is defined by its smooth, sweeping curve that culminates in a prominent, block-style central keystone. This keystone breaks the continuous arc to create an authentic masonry aesthetic, casting elegant shadows that shift throughout the day. The entire piece is supplied with a factory-applied white base primer, providing an exceptionally smooth surface that is ready for high-quality finishing coats.
This versatile architectural framing element is ideal for interior passageways, luxury villa entryways, and master suite transitions. Externally, it serves as an imposing pediment above arched windows or main entrance gates. For any outdoor applications, coating the surface with a high-quality, UV-resistant exterior paint is mandatory to protect the material from long-term exposure to sunlight and ensure lasting color fidelity.
Compared to heavy, fragile plaster or concrete alternatives, this lightweight alternative is remarkably easy to handle and install. The mounting process involves preparing a clean, dry substrate, applying a continuous bead of polyurethane (PU) mounting adhesive to the back, and securing the unit mechanically with screws. After filling the screw holes and joints, a light sanding and two coats of paint will complete the seamless, professional installation.
- This architectural arch frame is ideal for creating grand transitions in upscale residential and commercial spaces
- Indoors, it can be used to frame open-concept passages between dining rooms, formal living areas, or grand entry halls, defining separate zones while maintaining a spacious feel
- It is also excellent for luxury hotel lobbies, reception areas, and high-end retail spaces to establish a sense of classical symmetry
- Externally, it acts as a stately decorative pediment over arched windows or main entrance doors on classical, Mediterranean, or Georgian-style facades
- Thanks to its complete moisture resistance, it is also perfectly suited for covered terraces, pool houses, and spa entrances
- Begin by ensuring the mounting wall or facade surface is clean, dry, and structurally sound
- Measure the opening to align the arch perfectly
- Apply a generous bead of polyurethane (PU) mounting adhesive to the rear contact surfaces of the arch
- Press the frame firmly against the wall and secure it mechanically using screws at key structural points to prevent movement during the curing process
- Fill all screw holes and joints with a high-quality joint filler
- Once cured, sand the filled areas using 180-220 grit sandpaper to achieve a perfectly flush, seamless surface
- Finish by applying two coats of water-based or synthetic paint
- For exterior installations, a UV-resistant paint is required
- Thanks to the high-density, non-porous structure of the material, maintenance is minimal
- For interior installations, periodic dusting or wiping with a damp cloth and mild detergent is sufficient
- Avoid using harsh chemical solvents or abrasive pads which could degrade the painted finish
- For exterior applications, check the paint surface every few years to ensure the protective UV coating remains intact
- The surface can be washed with low-pressure water to remove outdoor dust and debris
