Composite Fence Panel Sizes: 1800 × 1800 mm, and the 29 mm Nobody Mentions
Panel size is where fencing orders go wrong, and it goes wrong in two different places — the panel itself, and the boards inside it.
These are 6 ft panels, but they are not 1829 mm
Composite fence panels are bought and sold as 6 ft × 6 ft, and for most runs that is exactly how they behave. But a true 6 ft is 1829 mm and ours is 1800 mm — every bay is about 29 mm shorter than the timber panel it replaces. One bay, nobody notices. Twelve bays, it is roughly a third of a metre. If you are matching into an existing fence line, or working to a boundary of fixed length, that is the number that decides whether the last bay fits. Measure the run. Do not assume 6 ft. The full imperial-to-metric table is in our composite fence panel sizes guide.
Calculate boards from the cover width, not the overall width
The privacy profile is 180 × 24 mm, but the boards lap — the effective cover is 172 mm. Work quantities from 172 mm. Using 180 mm under-orders by about 4.4%, and 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 are not interchangeable in a take-off.
Posts: a run of N bays needs N + 1
Each set includes one post. A run of N bays needs N + 1 posts, and every gate opening needs two more. This is the single most common short-order on a fencing project, and it is the one that stops an installation dead — you cannot finish a run with the last post missing.
One panel is 3.24 m² and about 55 kg
1800 × 1800 mm = 3.24 m² per set, roughly 55 kg including packaging. Two people per panel on site, and it is the weight figure that governs container loading — see the ordering table below.
The Fence Panel Range
Five panel styles, all 1800 × 1800 mm, all sharing the same posts and capping rail. Six colours run across the range — choose the style from the exposure and the use, then choose the colour.
Inside the Composite Fence Factory
Most search results for a composite fence factory are trading companies reselling containers they bought from plants like this one. These four photographs are ours, taken at the plant in Sihui, Zhaoqing, Guangdong — the same address that appears on the invoice and on the ISO certificates.
The extrusion hall — our own lines
WPC profiles are extruded here rather than bought in. A composite fence factory can show you this room; a reseller shows you a catalogue.
Finished goods, palletised and wrapped
Stock held in-house, which is why a 70-set minimum order does not have to wait for a full production run.
Loading for Nansha or Yantian
Ask any supplier which port they load from. A plant answers without checking; a reseller usually answers with a city.
The plant — Sihui, Zhaoqing
Guangdong Bangying New Material Co., Ltd., the legal entity on the invoice and on our ISO 9001 and ISO 14001 certificates, both valid to April 2027. Buyers and third-party inspectors are welcome.
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 |
|---|
| Privacy | Full — solid boards, no gaps | None | Screening is the requirement and the boundary is sheltered |
| Half trellis | Solid to two thirds, open above | Through the upper third | Exposed or coastal. Screening at eye level, load out of the posts |
| Full trellis | None — open lattice throughout | Through the whole panel | Definition rather than screening, or support for climbing planting |
| Carved | Partial — pattern cut through the face | Through the cut-outs | Feature bays where the view matters more than the screen |

Ordering: MOQ, Containers and What Actually Fills One
Composite is dense. On almost every fencing order the container reaches its weight limit before its volume limit, so plan in tonnes rather than cubic metres.
| Figure | What it means |
|---|
| Minimum order | 70 sets | Counted across the whole order — styles and colours can be mixed to reach it |
| One set | 1800 × 1800 mm | 3.24 m², about 55 kg including packaging |
| 20GP | 200 sets | 360 linear metres, roughly 11.5 t gross |
| 40HQ | 400 sets | 720 linear metres, roughly 23 t gross |
| Posts | N + 1 | One per set, plus one to close the run, plus two per gate opening |
| Privacy board cover | 172 mm | Section is 180 × 24 mm — calculate from 172, not 180 |
| Slatted board cover | 160 mm | Different section: 178 × 24 mm. Do not mix the two figures |
| Colours | Six | Black, blue grey, light grey, teak, walnut, white — available across the styles |
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 1829 mm, so each bay is about 29 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, especially if you are matching into fencing that is already there.
How many fence panels do I need?
Divide the run by 1.8 m and round up — then add one post. A run of N bays takes N sets and N + 1 posts, plus two extra posts for every gate opening. If the run turns a corner or steps down a slope, count each straight length separately rather than measuring the boundary as one number.
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. That is counted across the whole fencing order, not per style or per colour, so you can mix privacy, trellis and carved panels and several colours to reach it. 70 sets is well under a full container.
Choosing a style and colour
Which style should I use on an exposed or coastal boundary?
Half trellis, in most cases. A solid 1800 mm panel is a sail — wind load goes straight into the posts and their foundations, and that is what takes a fence down. The open upper third of a half trellis panel lets air through and takes load out of the system while keeping screening at eye level. If a timber fence on the same line has blown over before, that is the reason, and it is the argument for half trellis over full privacy.
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.
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, and light and planting read through it. That is a screen rather than a barrier. Most projects use carved panels as feature bays — the run facing a terrace or a seating area — with plain privacy panels along the rest of the boundary.
Supply
Are you a composite fence factory or a trading company?
A factory. The panels are extruded on our own lines in Sihui, Zhaoqing, Guangdong — the photographs above are ours, taken at the plant — and they ship FOB Nansha or Yantian. Buyers searching for a composite fence factory are welcome to ask which port we load from and who the legal entity on the invoice is: Guangdong Bangying New Material Co., Ltd., the same name on our ISO certificates. Those two answers separate plants from resellers faster than anything else.
What will you not claim?
We hold no EN 13501-1 reaction-to-fire classification — not a lower class, not a pending one: none. We do not publish a wind load rating for the panel or the post fixing, because foundations depend on ground conditions we cannot see. Tell us what your specification names and we will answer with the report number, the laboratory and the date, or say plainly that we do not hold it. A supplier who claims everything has usually tested nothing.
Can we get samples before ordering?
Yes, and for fencing we would encourage it. Samples are free — you cover the courier and we credit it against your first order. Ask for a board in the colour you are considering rather than a swatch: colour reads differently at panel scale, and on a carved pattern the depth of the cut and the way light passes through it are the two things a photograph does not convey.
Who do we buy from — Bohai Woods or Guangdong Bangying?
Bohai Woods is the brand; the legal entity is Guangdong Bangying New Material Co., Ltd., which is what appears on the business licence, the ISO certificates and the invoice. If you are verifying us as a supplier, those are the two names to expect, and they should match on every document we send you.
Send the run length, not the panel count
Give us the boundary length, the number of corners and gates, 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.
