High-Performance Carbon Fiber Enhanced Boat Bunk Beams
CarbonBunks™ are the new, high-tech dry stack storage bunk beam solution that ends the continuous replacement of plain lumber boards.
These beams are simply better for the boat, better for the customer, and better for your marina’s bottom line.
New. Better. Different.
CarbonBunks are engineered to outperform with advanced materials and proprietary high-tech components that work together as a robust system packed with features and benefits.
Modernize Outdated Storage Infrastructure
Upgrade your marina dry stack storage infrastructure to eliminate the hassle, problems, high cost and wasted labor of the continuous replacement of plain lumber boards with inferior coverings.
Plain lumber boards are a constant problem. They are cheap to buy but expensive to own, bad for business, wasteful, and unsustainable.
CarbonBunks are the smart choice if you are building a new dry storage building, installing an outdoor rack, revitalizing an existing facility, need robust beams for service racks — or want to stock a supply to replace plain boards as they fail.
Proven Strength & Performance at Port 32 Marinas
They hit a home run out of the park with these carbon fiber enhanced bunk beams. It’s not just big boats that put stress on rack bunks; smaller boats can concentrate the load right in the middle of the span. These are innovative, durable, better than lumber boards and a real game changer for efficient marina operations.
Product Benefits that Improve Marina Operations
Pultruded strand carbon fiber increases load capacity by 50%, and reduces weight by 40%.
Protects from saltwater, harsh weather, UV rays, breakage, and abrasive debris trapped in carpet.
Eliminates warping, cupping, knots, splitting, rotting, insect damage, and hull scratches.
Requires no cutting, routing, beveling or installation of carpet, PEM, or inferior plastic rails.
Upgrades facility appearance with a clean, high-tech profile; on-product marina branding available.
Advanced material science and engineering eliminate all potential failure points to last indefinitely.
Reduces hazardous elevated work to improve staff safety, while protecting vessels to lower liability risks.
No old growth timber, recycled materials, less waste and chemicals, and lower carbon emissions.
Lasts indefinitely to eliminate the cost and labor to constantly replace failed boards and carpet.
Comparative Strength Testing
Carbon fiber is a highly advanced material used to add strength and reduce weight for many high-tech industries like aviation, automotive, aerospace, energy, and infrastructure.
Technical testing performance comparisons show why the increased strength with decreased deflection of CarbonBunks compared to plain lumber boards makes a big difference for daily performance and long-term durability.
Solution Fit & Cost Optimization
CF Span works with customers to evaluate detailed designs for dry rack storage systems including capacity, configuration, mounting methods, load limits for each level, berth lengths, and typical boats.
We utilize these specifications to fit the correct beam for each bunk to optimize the configuration for the entire facility and right-size costs.
Schedule a meeting to discuss your project and review share design specifications to get the right performance fit and cost-optimized solution for your unique needs.
