Classical Arch Support Profile
Polure classical arch support profiles provide architectural corbel brackets at the spring points of interior door archways, hallway vaults, and exterior entrance arcades. Molded from high-density rigid polyurethane (150-220 kg/m³), these arch supports deliver sharp classical stepped mouldings with exceptional impact resistance while remaining lightweight and easy to position. Featuring a closed-cell composition with under 1% water absorption, they will not rot, swell, or crack under freeze-thaw cycles or indoor humidity. Operating stably across -100 °C / +80 °C with Class B2 fire safety, they arrive pre-coated in white acrylic primer. Installation is completed using continuous PU assembly adhesive, mechanical screws, and UV exterior paint.
Frequently Asked Questions
What material is used for the Polure classical arch support?
It is molded from high-density rigid polyurethane (150-220 kg/m³), offering crisp classical stepped details, light weight, and Class B2 fire safety.
Are classical arch supports load-bearing for heavy stone arches?
No, Polure arch supports are purely decorative elements. Structural loads of heavy arches or lintels must be independently supported.
Can classical arch supports be installed on exterior entrance arcades?
Yes, with water absorption below 1% and stability from -100 °C / +80 °C, they resist rain and frost. Outdoor use requires UV exterior paint.
How is the classical arch support installed under an archway?
Apply continuous PU assembly adhesive to the rear contact surface and wall junction, then secure with countersunk mechanical screws.
