Composite 3D Embossing Decking (round hole)

Round-void hollow WPC decking board with a 3D embossed surface. The round-void hollow version of our 3D embossed range, and the lightest of the three. Circular voids are the simplest way to take weight out of an extrusion, which makes this the board distributors reach for when freight weight is the binding constraint on a container.

Construction	Classic (uncapped) wood-plastic composite — not co-extruded
Warranty	Generation 1 — 10 years, stepped cover
Slip classification held	None on this grade
Colours	Teak, Redwood, Light grey, Grey, Coffee, Chocolate, Charcoal, Cedar
Profile drawing	Shown below — dimensioned section on request
MOQ / production	70 m² — 20 days for standard catalogue items
HS code / origin	3925.90 — Sihui, Zhaoqing, Guangdong, China

Warranty and evidence

Warranty — Generation 1, 10 years, stepped. Cover runs 100% in years 1–3, 80% in year 4, 70% in year 5, 50% in year 6, 40% in year 7, 30% in year 8, 20% in year 9 and 10% in year 10. It starts on delivery and signature at the destination port, not the factory gate, and covers peeling, cracking and overall uneven fading. Excluded: incorrect installation, impact damage, chemical attack and misuse.

Certification: ISO 9001 (IAS25924Q1473R0M) and ISO 14001 (IAS25924E0394R0M), valid to 29 April 2027. CE / CPR certificate M.2024.206.C97619, UDEM International Certification, valid to 11 March 2029. REACH is covered by a manufacturer’s declaration of conformity — a declaration, not third-party certification. We publish the numbers rather than a row of badges, because buyers who matter will ask for them.

Slip: we hold a third-party ramp classification — Intertek Shanghai Fengxian, 230625005SHF-001, AS 4586-2013 Appendix D, 15°, R10 — but it was measured on our co-extruded 23 × 138 mm profile ZSGJ138H23A. No slip classification is held on this grade, and we will not transfer one across. Pool surrounds and other barefoot wet areas are specified against DIN 51097, which is a different method again and one we do not yet hold. If your project needs either, we can test this profile at the same laboratory: fee up front, credited in full against the order.

Not yet tested on this profile: DIN 51097 (barefoot wet areas), BS 7976 pendulum PTV, ASTM D7032 / D7031 and ICC-ES. Our documentation route is European (CE/CPR, REACH) and Australian plus Chinese GB/T. If you are selling into a market that names US standards, tell us which ones before you order rather than after installation.

Buying this board

MOQ, lead time and samples. MOQ is 70 m² for decking, measured in square metres rather than full containers. Standard catalogue production runs 20 days, and sea freight to a UK port is about 55 days port to port on top of that, loading at Nansha (Guangzhou) or Yantian (Shenzhen). HS code 3925.90. Samples are free — you cover the courier and we credit it against your first order.

FAQ

What is the cross-section? The profile drawing is shown at the foot of this page. Ask us for the dimensioned version checked against current tooling before you order — we are re-verifying the section figures previously published here.

Is it slip rated? No classification is held on this grade, and we will not describe it as slip-resistant without a test behind that word. Our R10 result belongs to a co-extruded profile and does not transfer. Testing can be arranged, fee credited against the order.

Can I specify it poolside? Pool surrounds are barefoot wet areas, specified against DIN 51097. We do not hold that test on any profile yet and will not imply otherwise. We can arrange it.

Why is it the lightest of the three? Circular voids remove more material than square cells at the same wall thickness, and the solid board removes none. Ask for the drawings if you want to compare properly.
