Large Recycled Plastic Decking Joist

Build a subframe that lasts with the NeoTimber® Large Recycled Plastic Decking Joist - a durable, all-weather alternative to timber. Designed to support your NeoTimber® decking boards, this robust joist delivers strength and stability that outperforms traditional wood.

Made from 100% recycled plastic, the large plastic joist resists rot, moisture, and insects for long-term performance. Its eco-friendly composition supports sustainability while reducing maintenance demands. Each joist measures 120mm x 50mm x 3100mm, providing a solid framework for both ground-level and raised decking installations.

Use the large plastic decking joist with NeoTimber’s plastic posts and adjustable pedestals to create a secure, level foundation. As a reliable decking subframe solution for both ground-level and raised installations, it delivers consistent support and long-term stability, even in exposed outdoor environments.

Though colour and length may vary slightly due to the recycled materials, the product’s structural integrity remains unaffected. Each joist is cut slightly longer to meet performance standards. For best results, avoid cutting along its length, as this may reduce strength.

This plastic joist is perfect for anyone seeking a long-life, low-maintenance subframe that won’t degrade over time. It offers the reliability and resilience your decking project needs, without the drawbacks of timber.

Upgrade your frame today with the NeoTimber® Large Recycled Plastic Decking Joist for strength that stands the test of time.

Please note: Minor colour variations may occur due to recycled material sources but do not affect quality or performance. Slight length differences are also possible, as joists are cut longer to meet tolerances. We do not recommend cutting along the length, as this may reduce structural integrity.
