WPC timber tube is becoming one of the most innovative and versatile decorative materials for both exterior and interior projects. From façade screening to modern room dividers, from commercial ceilings to outdoor pergola cladding, WPC (Wood-Plastic Composite) timber tubes offer a premium wood-like appearance with superior durability, weather resistance, and long service life.

In this comprehensive guide, we explain everything you need to know about WPC timber tubes—what they are, how they are produced, their key features, standard sizes, installation applications, and why global wholesalers, contractors, and project developers increasingly choose this product over natural wood or aluminum profiles.

What Is WPC Timber Tube? (Definition & Material Composition)

WPC timber tube—also known as WPC hollow tube, WPC decorative profile, or WPC square/round tube—is a hollow structural profile made from wood-plastic composite materials. It combines the beauty of natural wood with the high performance of plastic polymers, creating a durable and low-maintenance architectural solution.

1.Material Composition

Typical WPC timber tube formulas include:

50–60% Wood Fiber
Provides natural wood texture and excellent rigidity.

30–40% High-Density Polyethylene (HDPE)
Improves waterproofing, anti-corrosion, and weather resistance.

10% Additives
Including UV stabilizers, colorants, anti-oxidants, and coupling agents.

This formula helps WPC timber tubes achieve:

• Longer service life
• Better color retention
• Stronger impact resistance
• Better performance in harsh outdoor climates

Compared with natural wood, WPC timber tubes do not rot, crack, warp, or attract termites.

2.Hollow Structure Design

The hollow structure delivers several advantages:

• Lightweight but strong
• Improved acoustic performance
• Lower material costs
• Easier installation

Hollow tubes also allow wiring, lighting, and ventilation integration for interior projects.

This makes WPC timber tubes suitable for commercial buildings, residential façades, office interiors, hotels, and outdoor pergola projects.

Production Process of WPC Timber Tube (Professional Factory Introduction)

Understanding the production process helps B2B buyers and importers evaluate factory strength and product reliability.

1.Raw Material Mixing

Wood fiber, HDPE, and additives are precisely mixed using high-temperature internal mixers. This ensures:

• Stable density
• Uniform color
• Better extrusion consistency

2.Extrusion Molding

The mixed materials are fed into advanced twin-screw extrusion lines. The mold shapes the timber tube into square, round, rectangle, or customized sections.

Key factors affecting product quality:

• Mold precision
• Screw speed
• Temperature control
• Vacuum forming technology

High-end factories in China (like those in Zhejiang, Anhui, and Shandong) use full-automatic extrusion lines for:

• Stable size tolerance (±0.2–0.5 mm)
• Uniform surface texture
• Improved mechanical strength

3.Surface Finishing

Factories typically offer:

3D Embossing
Deep grain texture close to real wood.

Co-extrusion WPC
A protective outer layer with better UV resistance.

Color Customization
Walnut, teak, maple, smoky grey, black wood, etc.

4.Cutting & Quality Control

Standard QC includes:

• Impact resistance test
• Colorfastness test
• Waterproof test
• Tensile strength test
• Size uniformity check

5.Packaging & Export

Most exporters ship timber tubes with:

• PE shrink film
• Protective corner pads
• Palletized bundles

Suitable for container loading without damage.

Main Features & Advantages of WPC Timber Tube

WPC timber tubes outperform traditional wood, PVC profiles, and aluminum decorative tubes in many aspects.

1.Excellent Weather Resistance

They can withstand:

• Strong UV exposure
• Heavy rain
• Snow & freeze–thaw cycles
• Salt spray in coastal climates

Ideal for outdoor façades and exterior screens.

2.Waterproof & Moisture-Proof

Unlike wood, WPC timber tubes:

• Do not swell
• Do not rot
• Do not mold

Suitable for humid climates in Southeast Asia, Middle East, and Africa.

3.Eco-Friendly & Sustainable

Made from recycled HDPE and wood flour:

• Low carbon footprint
• Recyclable
• No formaldehyde

Comply with international environmental standards.

4.Fire Resistance

Most WPC tubes reach:

• B1 fire rating (Building-grade flame retardant)

Ensures safety for commercial interiors.

5.Termite & Insect Proof

Wood fibers are fully encapsulated by plastic, preventing insect damage.

6.Durable & Long Service Life

Service life:

• 15–25 years outdoor
• 25–30 years indoor

7.Cost-Effective

Compared with aluminum cladding:

• Lower material cost
• Lower maintenance cost
