Exterior Roof Support Bracket
Polure exterior roof support brackets bring classic architectural detail and corbel aesthetics to eaves, gables, and roof overhangs. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these brackets offer wood-like mechanical toughness without rotting, cracking, or sagging over time. The lightweight material simplifies installation under roof projections without adding heavy structural loads to outer walls. Featuring a closed-cell physical structure with water absorption under 1%, they withstand severe weather, rain, ice, and temperature shifts from -100 °C / +80 °C. Factory-primed with white acrylic primer, they mount using continuous polyurethane assembly adhesive on wall contact edges combined with countersunk mechanical screws, requiring paint finish with elastic UV-resistant facade paint.
Frequently Asked Questions
Are Polure exterior roof support brackets load-bearing for roof rafters?
No, Polure exterior roof support brackets are decorative architectural corbels and non-load-bearing. Roof structures must be self-supporting.
Will exterior roof support brackets rot or warp in rain and snow?
No, with water absorption under 1% and stability between -100 °C / +80 °C, polyurethane will not rot, warp, swell, or deteriorate.
How are exterior roof support brackets mounted under roof eaves?
Apply continuous PU assembly adhesive on all back contact surfaces, fix with mechanical countersunk screws into structural wall studs, fill screw holes, and paint.
What paint is needed for exterior roof support brackets?
They must be painted with an elastic, UV-resistant exterior facade paint to prevent UV fading and weathering.
