SeaPile® and SeaTimber® | Marine Building Materials

Structural Composite Lumber for Even the Most Challenging Marine Applications

SeaPile® and SeaTimber® by Bedford Technology, a Tangent Technologies company

are advanced composite plastics, engineered for the marine industry. Manufactured from recycled HDPE and fiberglass strand and rod, the stiffness of the product can be varied and controlled to suit your specific marine application. Increase your life-cycle cost and return on investment by using these product lines as an alternative to traditional wood, metal and concrete.

How is it Made? Multi-X Technology

Our environmentally-friendly three-stage Multi-X Technology manufacturing process includes first making a cold core (internal filler). Next, we extrude an annulus material including fiberglass rebar and fiberglass strands, which determines the strength of the plastic timber based on the number of bars. Finally, a dense skin that creates a low-friction surface is extruded over the cold core and rebar. The skin comes in many different colors and can be customized for your project’s specific requirements.

Benefits of SeaPile® and SeaTimber® by Bedford Technology, a Tangent Technologies company

Products created with Multi-X technology can withstand heavy impacts by absorbing energy through recoverable deflection. SeaPile® and SeaTimber® by Bedford Technology offer coastal protection without damaging the environment. Both of these products provide a durable and sustainable product that can absorb energy from high impact and are impervious to marine borers.

As a fender material, SeaPile® and SeaTimber® offer a low friction coefficient. When barges, vessels and boats rub up against this product, it is easily deflected without causing damage to the vessel or the product, whereas with traditional wood and metal, dents, splintering and breakage can occur with heavy impact over time. Contact us today to learn more about SeaPile® and SeaTimber® marine building materials and how they can help you with your next project.

Our SeaPile® and SeaTimber® Manufacturing Process

process 1

Raw Material

We take in HDPE recycled plastic from post industrial and post consumer waste. Items found in these types of recycled waste include milk jugs and juice bottles; butter and yogurt tubs; shampoo bottles; industrial containers; agricultural (water) tanks; and motor oil bottles.

process 2

Prepare for Extrusion

After the bales of recycled material are received, we break down the material through our unique process filtering out paper labels and other unwanted items from the mix.

Extrusion Processes

SeaPile® and SeaTimber® are manufactured with fiberglass strand and rod, using our Multi-X process. The stiffness of the product can be varied and controlled to suit your specific marine application needs. With our Multi-X technology, SeaPile® and SeaTimber® products withstand heavy impacts by absorbing energy through recoverable deflection. It’s no surprise our products have been the longest lasting, tested and proven marine solution for over 20 years.

Final Product

Our final product is a durable, long-lasting recycled plastic lumber board that can be constructed to fit your specific needs for your project or design. No matter the application, we offer an unbeatable selection of recycled plastic lumber products to choose from with a wide selection of colors for whatever aesthetic you’re going for.

Marine Green Construction

SeaPile® and SeaTimber® are engineered for marine applications. Both products are manufactured out of recycled plastic and are non-polluting; they don’t leach chemicals that can harm marine life because they don’t require chemical treatment, unlike treated lumber. SeaPile® and SeaTimber® marine building materials are ideal for your marine project.

Protect the environment by choosing structural recycled plastic lumber, but also earn points from the LEED Certification Program. These points are awarded for implementing specific sustainability practices, including building material requirements. Our plastic lumber helps protect the environment one milk jug at a time. So far, Bedford Technology has saved millions and millions of pounds of plastic from the landfill by turning it into a dependable building material that is recycled and can also be recycled at the end of the product life-cycle.
