A co-extruded second-generation WPC fence panel with a decorative alternating slat profile — combining partial privacy, airflow, and architectural appeal for residential, commercial, and landscaping projects.
The Treslam GJ23 is a semi-private composite fence panel built for projects that need more visual character than a standard solid fence, without the full openness of a slatted design. The alternating wide and narrow board layout creates a structured, decorative rhythm — partial privacy, natural airflow, and a distinctly modern finish.
Unlike our first-generation AM60+AM98 panels, the GJ23 uses co-extruded second-generation WPC technology — a polymer shell fused directly to the wood-plastic core for superior surface durability, fade resistance, and a sharper wood grain finish. Available in 9 colors including Walnut, Black, and Teak, with a 20-year manufacturer warranty. MOQ 50 sets, 15–25 day lead time.
The GJ23 Co-Extruded WPC Fence by Treslam is a sophisticated semi-private fencing solution designed for both aesthetics and performance. This model combines alternating wide and narrow composite boards to achieve a structured slatted appearance that offers both visual interest and partial privacy.
Manufactured using advanced co-extrusion technology, GJ23 offers excellent weather resistance, superior surface durability, and vibrant, fade-resistant colors. It’s a favorite among architects and designers for its ability to blend privacy with airflow, making it perfect for modern homes, villas, or urban properties.

FAQ
Q: What is the difference between the GJ23 and the AM60+AM98 panel?
A: Both are semi-private alternating slat designs, but the GJ23 is a second-generation co-extruded WPC panel — a significant upgrade in surface quality and durability. The polymer cap layer is fused directly to the wood-plastic core during manufacturing, giving the GJ23 better UV resistance, a sharper 3D wood grain finish, and longer service life. The AM60+AM98 is a first-generation WPC panel — solid, reliable, and more cost-effective for projects where budget is the priority. We can advise which is better suited to your project spec.
Q: What does the alternating slat design look like?
A: The GJ23 alternates between a wider and narrower composite board in a repeating pattern. This creates a structured rhythm of shadow and depth across the panel face — more visual interest than a uniform slat or solid board design, while still maintaining a clean, contemporary appearance.
Q: What is the 20-year warranty coverage?
A: The 20-year manufacturer warranty covers structural integrity and performance against rot, insect damage, and material degradation under normal outdoor conditions. Full warranty documentation is available on request for project specifications and developer requirements.
Q: Is the GJ23 suitable for high-end residential and hospitality projects?
A: Yes — the GJ23's co-extruded finish and decorative slat profile make it a popular specification for premium residential developments, boutique hotels, resort boundaries, and commercial landscapes where design quality is as important as durability.
Q: What are the payment and supply terms?
A: Standard payment is 30% T/T deposit, 70% balance against bill of lading. L/C is also negotiable. Supply capacity is 100,000 sets per year with consistent lead times of 15–25 working days.
Q: Can the GJ23 be specified into a project tender?
A: Yes. We provide CE, FSC, ISO, and Intertek certification documents, full technical datasheets, and test reports covering UV resistance, weatherproofing, moisture resistance, rot and insect protection, and antibacterial performance — all suitable for project submissions and developer documentation.
