Key Features & Benefits

FeatureBenefit
Superior Water & Moisture ResistanceWater absorption rate ≤ 0.5% (far below the international WPC standard of ≤ 3%) ; effectively prevents rotting, swelling, and warping even in prolonged wet conditions
UV Stability & Color RetentionAdvanced UV stabilizers and co-extruded protective capstock deliver 3,000+ hours UV testing with no visible fading; withstands extreme temperatures from -40°C to 80°C without cracking or color loss
Class B1 Fire RatingSelf-extinguishing with minimal smoke emission when heat source is removed; meets international fire safety standards for residential and commercial applications
Zero Formaldehyde & Eco-FriendlyMade from recycled wood fiber and food-grade polymer resins; contains zero formaldehyde, zero heavy metals, zero VOCs; 100% recyclable
Termite, Mold & Rot ResistantWood fibers are fully encapsulated within the polymer matrix — mold, mildew, and insects have nothing to feed on, ensuring 15-25 years service life (3-8 times longer than natural wood) 
Maintenance-FreeNo painting, sealing, or anti-corrosion treatment required; surface is stain-resistant and cleans easily with soap and water 
Excellent WorkabilityCan be cut, drilled, nailed, and screwed using standard woodworking tools; compatible with hidden fastener systems for quick assembly

Structural Design

The hollow interior (typically 2- 4 internal cavities) significantly reduces weight by 30%-50% compared to solid wood while maintaining structural strength through internal reinforcing ribs. This design also enables creative integration of LED lighting, greenery, or decorative elements within the tube cavities.

Applications

WPC square timber tubes are versatile and suitable for a wide range of applications:

Architectural & Structural

  • Pergolas & Gazebos: Frames, beams, and support columns

  • Fencing & Railings: Fence posts, deck railings, staircase balustrades

  • Outdoor Furniture: Table and chair frames, planter boxes, trellises 

Interior Design

  • Ceiling Systems: Decorative ceiling battens and suspended ceiling frameworks

  • Wall Cladding: Accent walls, room dividers, decorative panels

  • Commercial Spaces: Hotel lobbies, office partitions, retail display structures

Municipal & Infrastructure

  • Boardwalk & Bridge Railings: Trail posts, public area partitions

  • Sound Barriers: Traffic noise insulation barriers

  • Agricultural Applications: Greenhouse brackets, storage racks

Installation Guidelines

Quick and efficient installation:

  1. Cutting: Use standard woodworking saw blades to cut tubes to required length

  2. Fixing: Secure using screws, nails, or hidden fastener systems

  3. Connection: Tongue-and-groove interlocking or clip-lock systems enable fast, nail-free assembly

  4. Integration: Hollow interior allows routing for electrical wiring, LED lighting, or structural reinforcement sleeves where needed

Installation Note: For load-bearing applications, internal steel reinforcement may be recommended. Installation efficiency: one worker can typically install 15–20 square meters per day — 2x faster than solid wood.
