Composite Fence Panels: Choosing the Style Your Site Needs, and Ordering the Right Quantity
Two things decide a composite fencing order, and neither of them is colour. The first is exposure — whether the boundary is sheltered or takes wind — because that is what decides between a solid panel and an open one, and it is what takes fences down. The second is arithmetic: panels, posts and containers, where the same three mistakes are made on almost every order.
There is a planner below that turns a run length into panels, posts, weight and container split. Colour comes last, and all six run across all the styles — it is the one decision you can leave until the end.
Composite Fence Panels: The Four Numbers That Govern an Order
Everything else on this page is an explanation of one of these four.
Privacy or Trellis: Exposure Decides It, Not Taste
A solid 1800 mm fence is a sail. That single fact explains most of the difference between the styles, and most of the fences that come down in a gale.
A solid panel presents its whole area to the wind, and that load goes into the posts and their foundations. An open upper third lets air pass instead. This is why half trellis is the sensible default on an exposed or coastal boundary, and why a timber fence that has blown over on the same line is an argument for changing the style rather than just the material. We do not publish a wind load rating — post fixing and foundation design belong to whoever is installing, and they depend on ground conditions we cannot see.
Composite Fencing Styles Compared: Privacy, Half Trellis, Full Trellis, Decorative
Four styles, six colours, chosen independently. Pick the style from the exposure and the use; colour is the last decision, not the first.
| Style | Screening | Wind through the panel | Specify it when |
|---|---|---|---|
| <strong><a href='/collections/wpc-privacy-fencing'>Privacy</a></strong> | Full — solid boards, no gaps | None | Screening is the requirement and the boundary is sheltered |
| <strong><a href='/collections/wpc-half-trellis-fencing'>Half trellis</a></strong> | Solid to two thirds, open above | Through the upper third | Exposed or coastal. Screening at eye level, load out of the posts |
| <strong><a href='/collections/wpc-full-treli-fencing'>Full trellis</a></strong> | None — open lattice throughout | Through the whole panel | Definition rather than screening, or support for climbing planting |
| <strong><a href='/collections/wpc-carved-fencing'>Carved</a></strong> | Partial — pattern cut through the face | Through the cut-outs | Feature bays where the view matters more than the screen |
Fence Run Planner: Panels, Posts and Containers
Enter the boundary. This works out panels, how many posts you actually have to order on top of the ones that come with them, the weight, whether you clear the minimum order, and how it splits across containers.
Measure the Run Before You Order
Five things. The two people skip are the legs and the gates, and those are the two that change the post count.
Along the line the fence will actually follow, not the length of the garden. If the boundary is not straight, you also need the next item.
Each straight leg rounds up to a whole panel on its own, so a boundary that turns two corners needs up to two more panels than the same total length in one straight run. This is the most common reason a delivery is one panel short.
Every opening needs two extra posts beyond the run, and the gate leaf and its hardware are a separate order line.
If you are continuing a timber run, measure an existing bay. Timber panels are usually 1828 mm; ours are 1800 mm, and that difference compounds along the line.
Slope means the run steps down bay by bay rather than following the ground. Exposure decides privacy versus half trellis. Both belong in the enquiry, because both change what we would quote.
The Three Mistakes That Make an Order Short
These are not unusual. They are what goes wrong on most first orders, and all three are arithmetic rather than judgement.
They are 6 ft panels, but they are not 1828 mm
Composite fence panels are bought and sold as 6 ft × 6 ft, and for most runs that is how they behave. But a true 6 ft is 1828 mm and ours are 1800 mm — every bay is about 28 mm shorter than the timber panel it replaces. One bay, invisible. Twelve bays, about a third of a metre. Against a fixed boundary or an existing fence line, that is what decides whether the last bay fits.
Calculate boards from the cover width, not the overall width
The privacy profile is 180 × 24 mm, but the boards lap, so the effective cover is 172 mm. Quantities worked from 180 mm under-order by about 4.4% — at container scale that is the shortfall you end up air-freighting. The slatted profile is a different section again, 178 × 24 mm covering 160 mm. The two figures are not interchangeable.
Posts are counted per run, not per panel
Each set includes one post. A run of N bays needs N + 1 — the last one closes the run — and every gate opening needs two more. This is the single most common short-order in fencing, and it is the one that stops an installation, because you cannot finish a line with the end post missing.
Evidence for a Composite Fencing Specification
What carries a reference number you can check, and what does not. Where the answer is no, testing can be arranged on the specific profile a project intends to use — cost paid up front and credited in full against the order.

Composite Fencing: Common Questions
Sizes and quantities
Are these 6ft composite fence panels?
They are sold as 6 ft × 6 ft and used that way, but the panel is 1800 × 1800 mm. A true 6 ft is 1828 mm, so each bay is about 28 mm shorter than the timber panel it usually replaces. Over one bay it is invisible; over a twelve-bay run it is about a third of a metre. Measure the boundary and count the bays before ordering, particularly if you are matching into fencing that is already there.
How many fence panels and posts do I need?
Divide the run by 1.8 m and round up for the panels. For posts, take that number, add one to close the run, then add two for every gate opening. One post comes with each panel, so what you add to the order is the difference. If the boundary turns corners, count each straight leg separately — each one rounds up to a whole panel on its own.
How many panels fit in a container?
A 20GP takes 200 sets — 360 linear metres, roughly 11.5 t gross. A 40HQ takes 400 sets — 720 linear metres, roughly 23 t. Composite is heavy for its bulk, so the weight limit binds before the volume limit on nearly every order. If you are combining fencing with decking in one container, work the tonnage first.
What is the minimum order?
70 sets, counted across the whole fencing order rather than per style or per colour. You can mix privacy, trellis and carved panels and several colours to reach it. 70 sets is well under a full container.
Choosing style and colour
Which style should I use on an exposed or coastal boundary?
Half trellis, in most cases. A solid 1800 mm panel presents its whole area to the wind, and that load goes into the posts and their foundations — which is what fails first. The open upper third lets air through while keeping screening at eye level. If a timber fence on the same line has blown over before, that is the argument for changing the style, not just the material. We do not publish a wind load rating; post fixing and foundation design belong to the installer and depend on ground conditions.
Is colour tied to style, or to market?
Neither. All six colours — black, blue grey, light grey, teak, walnut and white — run across the styles, and any of them ships to any market. Choose the style from the exposure and the use, then choose the colour separately. Colour is the last decision in a fencing specification, not the first.
Do decorative panels give privacy?
Partially. A carved panel has the pattern cut through the board face, so it screens the view without blocking it — light and planting read through it. That is a screen rather than a barrier. Most projects use carved panels as feature bays, on the run facing a terrace or a seating area, with plain privacy panels along the rest of the boundary.
Certification and supply
Is composite fencing fire rated?
Ours is not. We hold no EN 13501-1 reaction-to-fire classification — not a lower class, not a pending one: none. If your specification, your insurer or your local authority requires a reaction-to-fire class, we cannot satisfy that today. Testing can be arranged on the specific profile a project intends to use, cost paid up front and credited in full against the order, but it has to be raised at design stage rather than at inspection.
What documents do you hold?
ISO 9001 and ISO 14001 valid to April 2027, and CE marking under CPR — certificate M.2024.206.C97619 from UDEM International Certification, a notified body, valid to 11 March 2029. Ask any supplier for the certificate number and the issuing body rather than a logo; a logo on a page is not a certificate.
Who are we actually buying from?
Bohai Woods is the brand; the legal entity is Guangdong Bangying New Material Co., Ltd., in Sihui, Zhaoqing, Guangdong. That is the name on the business licence, the ISO certificates and the invoice. If you are running supplier verification, those are the two names to expect and they should match across every document we send.
Can we see the panels first?
Samples are free — you cover the courier and we credit it against your first order. For fencing, ask for a board in the colour you are considering rather than a swatch: colour reads differently at panel scale. On a carved pattern, ask for the pattern itself, because the depth of the cut and the way light passes through it are the two things a photograph does not convey.
Boundary length, how many straight legs, how many gate openings, the exposure, and the destination port. We come back with the panel and post schedule, the container split, and a plain statement of which documents we hold and which we do not.
Give us the run and the exposure and we will tell you the style, the panel and post schedule and the container split — and where our evidence stops.
