Classic Composite Decking （solid）140*21.5

Classic solid WPC decking board, 140 × 21.5 mm — the uncapped value line. This is our first-generation board: solid section, no co-extruded cap. It is the price-led option for projects where a capped surface is not required, and it is honest about what that means — a 10-year warranty rather than 15, and no slip classification on this grade.

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.

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 the classic grade, and we will not transfer one across. If your project needs it on this board we can put it through 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

Is this board co-extruded? No. It is the classic uncapped line, which is exactly why it costs less than our co-extruded boards. If you need a capped surface, look at the 23 × 138 or 23 × 148 co-extruded profiles instead.

Why 10 years and not 15? Fifteen years is our Generation 2 co-extruded schedule. This is Generation 1, and its schedule runs to 10 years. We would rather quote you the right document than the longer number.

Is it slip rated? No classification is held on this grade. Our R10 result belongs to a co-extruded profile and does not transfer. We can arrange testing on this board, fee credited against the order.

What is the MOQ? 70 m², measured in square metres rather than full containers.
