DECNO Walnut composite tube — 3000 × 100 × 50 mm. Hollow WPC section with 3 internal chambers for a strong, light substructure, in a natural walnut brown. Waterproof, UV-, moisture- and insect-resistant. Ideal as a loadbearing structure for composite decking. Request your DECNO quote.
- Three-chamber hollow section — a hollow design with three internal compartments that optimises the strength-to-weight ratio — as strong as a solid tube, but far lighter to transport and handle.
- Natural Walnut shade — a finish that matches DECNO composite decking boards, for the parts of the structure visible at the terrace edge.
- High-density composite wood (WPC) — waterproof, resistant to UV, frost, insects and termites — unlike timber structures, which rot over time.
- Zero upkeep — needs no treatment, no stain and no additional protection — once installed, it lasts without intervention.
- Suits every installation method — can be laid directly on adjustable PVC pedestals, on a concrete slab or on stabilised ground for optimal ventilation under the terrace.

Frequently Asked Questions
Frequently asked questions
Everything about
this product
What is a composite tube and what is it for?
The composite tube is the structural element laid on the ground or on pedestals that supports the decking boards. The DECNO Walnut composite tube gives a light structure thanks to its 3 internal chambers, while providing the mechanical strength needed to carry the weight of the terrace and its users.
Why choose a composite tube rather than timber?
Unlike natural timber, which rots, distorts and needs regular treatment, the WPC composite tube resists moisture, insects and UV over the long term. It keeps its shape and its mechanical strength over time, even in prolonged contact with the ground or with damp.
How is the Walnut composite tube installed?
The composite tube is laid perpendicular to the direction of the decking boards, generally spaced 30 to 40 cm apart depending on the recommendations. It can be installed on adjustable PVC pedestals for a raised, ventilated terrace, on a concrete slab, or directly on stabilised, drained ground.
What is the difference between the Teak and Walnut tubes?
Both tubes have the same three-chamber hollow structure and the same dimensions and technical performance. The difference is purely visual: Teak has a warm golden brown, Walnut a natural walnut brown. The choice depends on how you want it to sit with your decking boards.
What spacing should be kept between composite tubes?
The recommended spacing depends on the direction of the decking boards and on how the terrace will be used (residential or commercial). Contact the DECNO team through the quote form for precise recommendations matched to your project.
Does the Walnut composite tube need maintenance?
No. The DECNO composite tube needs no particular upkeep once installed. Unlike timber, which must be treated regularly against damp and insects, the WPC tube keeps its structural properties with no intervention at all.
