Faux Wood Wheel Selection and Installation Guide

Polyurethane decorative wheels are produced using a closed-cell rigid polyurethane structure. The material features a nominal density target of 150-220 kg/m³ (obiettivo ~160 kg/m³), operating within a density range of 150 to 150-220 kg/m³ (obiettivo ~160 kg/m³). This high-density formulation limits water absorption to under 1%, preventing rot, fungal growth, and freeze-thaw damage in cold climates.

Thermal resistance spans from -100 °C / +80 °C, allowing structural integrity to remain unchanged during extreme weather shifts. Unlike authentic timber, these components do not warp, split, or expand when exposed to high moisture levels, making them suitable for long-term outdoor exposure.

Faux wood wheels serve strictly as decorative elements and possess zero load-bearing capability. Under no circumstances should these components be integrated into structural framing, load-supporting columns, or weight-bearing assemblies.

When selecting dimensions, the wheel diameter should complement the scale of the wall or facade. For standard wall accents, diameters between 50 cm and 90 cm maintain visual balance. Larger exterior gables or commercial tavern facades can accommodate diameters of 100 cm to 120 cm. Oversizing in narrow spaces can overwhelm the architectural composition, while undersizing reduces visual impact.

International transport across European borders requires standardized packaging to prevent edge chipping during freight. Because rigid polyurethane is lightweight compared to natural hard oak, freight handling costs are substantially lower. Polure products are shipped in protective corrugated packaging designed to withstand stack pressures during multi-country transit.

Upon delivery, store the components flat in a dry space away from direct heat sources. Prior to installation, allow the components to acclimate to ambient site temperatures for at least 24 hours to ensure stable bonding during application.

Installation requires a clean, dry, and dust-free substrate. Standard silicone adhesives are strictly prohibited as they fail to form a permanent bond with polyurethane surfaces. Use only dedicated polyurethane (PU) mounting adhesives for initial surface attachment.

Mechanical fastening with stainless steel screws is mandatory to ensure permanent safety and resistance against wind loads on exterior facades. If joining perimeter trims or mounting embedded frame edges, cut joints at a precise 45-degree miter angle. Drive screws through the thickest sections of the wheel hub or rim, counter-sinking screw heads slightly below the surface for subsequent patching.

Decorative wheels leave the factory pre-primed. Applying an additional layer of primer is optional, depending on the specifications of the selected topcoat system. Screw holes and joint seams must be filled with exterior-grade filler putty once the adhesive cures fully.

After the putty dries, sand all filled areas smooth using grana 180-220 sandpaper. For exterior installations, applying UV-resistant paint is mandatory to prevent surface chalking and discoloration under solar radiation. Apply a minimum of 2 coats of exterior acrylic or polyurethane paint to achieve full coverage and long-term weatherproofing.

Review these critical factors prior to purchasing and installing polyurethane decorative wheels:

• Verify that the installation substrate is solid brick, concrete, or reinforced timber.
• Confirm that the application does not require load-bearing structural support.
• Ensure polyurethane (PU) adhesive and mechanical screws are specified, not silicone.
• Select UV-rated exterior paint systems for outdoor applications.
• Check clear dimensions to ensure proper scaling on wall or ceiling surfaces.
