Planeo 4061 Deep Hybrid WPC Aluminum Plank (11 3/4″ x 4″)
The Geolam Planeo 4061 is a deep hybrid architectural plank measuring 11 3/4″ x 4″, produced by internally bolting Geolam hybrid profiles together to form a single rigid board with an anodized aluminum alloy core (A6063S-T5 Series 6000) and sanded wood/polypropylene composite (WPC) outer skin. Its combination of a wide 11 3/4″ face and a substantial 4″ depth delivers a secondary moment of 2,010.35 cm⁴ along its length axis, making it one of the most capable profiles in the Planeo range for bold decorative fins, large brise-soleil systems, and high-impact exterior façade applications where both visual presence and long-term dimensional stability are required. The sanded WPC grain surface replicates the warmth and texture of stained hardwood with zero maintenance across its full service life. Available in custom lengths only, certified non-combustible per ASTM E-136.

Key Benefits
| Authentic Wood Appearance | The Planeo 4061’s wide 11 3/4″ face combined with its deep 4″ profile delivers a bold, timber-scale wood-grain aesthetic with shadow depth and presence that reads clearly across large exterior façades and high-visibility architectural screen applications. |
| Non-Combustible | Certified non-combustible per ASTM E-136 (appendix), making the Planeo 4061 suitable for fire-regulated commercial, high-rise, and institutional projects. |
| Zero Maintenance | The Planeo 4061 never requires staining, sealing, or painting. It resists UV fading, moisture, and weathering without any periodic treatment throughout its full service life. |
| Performance | The internally bolted aluminum alloy core delivers a secondary moment of 2,010.35 cm⁴ along the board’s length axis, with a thermal expansion coefficient of 23.4 μm/m/°C for consistent dimensional stability across all climates and span lengths. |
| Custom Lengths | Available in custom lengths only, allowing projects to specify exact dimensions and eliminate on-site cutting waste. Contact Geolam for available length options for your project. |

Installation Overview
| Fastening options | InPull nut (M6–M12), blind nut, self-tapping screw, flange bolt, or plug system |
| Cutting (important note) | The Planeo 4061 is assembled from multiple internally bolted hybrid profiles. Boards may only be field-cut within the 2″ section at each end that extends past the end bolts. Do not cut anywhere else along the length as this may compromise the board’s integrity. Use a fine-tooth saw for all cuts. |
| Expansion gaps | Pre-drilled holes 2–4 mm wider than bolt shaft. Washers required. 0.92 mm/m expansion per 40°C difference. |

Frequently Asked Questions
| What is the Planeo 4061 made of? | The Planeo 4061 is assembled from multiple Geolam hybrid profiles (typically Soleo) that are bolted internally to form a single wide deep plank, with an anodized aluminum alloy core (A6063S-T5, Series 6000) and a sanded wood/polypropylene composite (WPC) outer skin. |
| Is it fire-rated? | Yes. The Planeo 4061 is certified non-combustible per ASTM E-136 (appendix), meeting fire safety requirements for commercial, multi-family, and institutional projects. |
| Can it be cut on site? | Only partially. The Planeo 4061 may be shortened by cutting within the 2" section at each end that extends past the internal bolts. Do not cut anywhere else along the board's length as this may compromise its integrity. Please specify your required length when ordering. |
| What finishes are available? | Four standard colors with an 800 lineal ft minimum: Teak, Moleskin, Rosewood, and Ebony. Non-standard colors Carbon and Bilinga require a 5,000 lineal ft minimum and 90-day lead time. Custom colors are available at 6,000 lineal ft minimum. |
| Can it be used indoors? | Yes. The Planeo 4061's deep wide profile is well suited to interior lobby feature walls, large decorative fin installations, and statement ceiling elements where a substantial timber-scale wood-grain aesthetic is required. |
