High Density Column Head
Polure high density column heads serve as durable architectural capitals for interior pilasters and decorative exterior column structures. Engineered from rigid polyurethane with high density (150-220 kg/m³), these column heads deliver wood-like structural rigidity and high impact resistance while maintaining a lightweight footprint. The closed-cell material features water absorption under 1%, protecting column structures from moisture damage, mold growth, and rotting in high-humidity indoor or outdoor environments. Fire safety rated B2 and thermally stable between -100 °C / +80 °C, each piece arrives pre-primed with a factory white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive along contact seams, securing with countersunk mechanical screws, filling holes with facade filler, sanding smooth with 180-220 grit, and painting with topcoat paint.
Frequently Asked Questions
Are Polure high density column heads load-bearing?
No, Polure high density column heads are decorative non-load-bearing components. Weight must be supported by an internal steel core profile.
What density is used for high density column heads?
They are produced from rigid polyurethane with a density of 150-220 kg/m³ (production target ~160 kg/m³), providing wood-like mechanical strength and B2 fire rating.
Can concrete be poured inside a high density column head?
No, NEVER pour concrete inside polyurethane column components as curing heat will deform and damage the polyurethane shell.
How is a high density column head installed?
Apply continuous PU assembly adhesive to rear contact edges, secure with mechanical screws, fill screw holes with filler, sand, and paint.
