Classical Pillar Shaft
Polure classical pillar shafts provide central vertical body framing for architectural columns, porch posts, and decorative wall pilasters. Formed from high-density rigid polyurethane (150-220 kg/m³), these hollow pillar shafts deliver wood-like mechanical durability and structural stability without adding immense dead weight to building foundations. The closed-cell physical matrix ensures water absorption under 1%, protecting outdoor entrance columns and interior pilasters against rot, swelling, mold, and humidity damage. Rated B2 for fire safety and dimensionally stable from -100 °C / +80 °C, each shaft section comes factory pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive along contact surfaces and vertical seam joints, securing with mechanical screws, filling joint lines with facade filler, sanding smooth with 180-220 grit, and painting with topcoat paint.
Frequently Asked Questions
What material is used for Polure classical pillar shafts?
Polure classical pillar shafts are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are classical pillar shafts load-bearing?
No, Polure classical pillar shafts are decorative non-load-bearing elements. Structural loads must be supported by an internal steel core profile.
Can concrete be poured inside a classical pillar shaft?
No, NEVER pour concrete inside polyurethane shafts as hydration heat and expansion will damage the polyurethane material.
How do you install classical pillar shafts?
Apply continuous PU assembly adhesive along contact edges and seams, secure with mechanical screws, fill joint lines with filler, sand, and paint.
