Composite decking joists & support beams
Build your decking to last
Ecodek composite joists and support beams are an ideal alternative to timber as they’re weather resistant, hard wearing and will not rot, splinter or warp.
They come in two styles – Low Profile Support Beams and deeper profile Supastiff Joists, ensuring that you have the right substructure no matter where your deck is being installed.
Low profile support beams
- Profile: 40mm x 48mm
- Ideal for installations with a low distance from the ground (although we recommend no less than 80mm)
- Can be used with our pedestals or heavy duty support posts
- Made from composite wood to combat rising damp and protect the decking above
- Will not rot, splinter or warp
- Should be supported by pedestals or packers at every 500mm intervals or less.
Supastiff deep profile joists
- Profile: 38mm x 88mm
- Ideal for decking on raised outdoor dining areas, leisure areas and balconies
- Can be used with our pedestals or heavy duty support posts
- Made from composite wood to combat rising damp and protect the decking above
- Will not rot, splinter or warp
- Should be supported by pedestals or packers every 1000mm or less.
