Outdoor Architectural Columns
Polure outdoor architectural columns create timeless classical grand entrances, porch colonnades, and garden pergola surrounds. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these columns provide wood-like mechanical durability and hail resistance without rotting, warping, or cracking under extreme weather. Featuring hollow interiors, they are non-load-bearing decorative covers designed to enclose internal structural steel posts; concrete must never be poured inside. Their closed-cell structure keeps water absorption under 1%, resisting severe rain, frost, and mold growth across temperature ranges from -100 °C / +80 °C. Certified B2 for fire safety, each piece comes pre-coated with a white acrylic primer. Installation requires surface alignment, applying polyurethane assembly adhesive along joint interfaces, securing with countersunk mechanical screws, filling seams with facade putty, and finishing with UV-resistant exterior paint.
Frequently Asked Questions
What material are Polure outdoor architectural columns made of?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing timber-like strength, high impact resistance, and B2 fire safety.
Can Polure outdoor architectural columns carry structural roof loads?
No. Polure outdoor architectural columns are hollow and non-load-bearing. Any structural load must be supported by an internal steel profile.
Is it safe to pour concrete inside Polure outdoor architectural columns?
No, concrete must NEVER be poured inside polyurethane columns, as curing concrete expansion can rupture or distort the column shell.
How are outdoor architectural columns installed and finished?
They are joined using continuous PU assembly adhesive and countersunk screws, filled with exterior putty, and painted with elastic UV-resistant exterior paint.
