WPC Decking Manufacturer Supplying Poland — and the Countries Polish Crews Build In

The Decking Range

Capped co-extrusion and classic uncapped, hollow and solid. Six of the sections Polish distributors order most — the full schedule runs to well over a hundred.

Co-extrusion 23 × 138

Capped, hollow, round chamber

The main capped section. This is the profile our slip test was run on.

View product →

Co-extrusion 23 × 148

Capped, hollow, premium

Wider capped board, four-sided cap. The usual choice for terraces in full sun.

View product →

Co-extrusion solid 20 × 140

Capped, solid core

Solid throughout. Specified for commercial traffic and exposed edges.

View product →

3D embossed, round chamber

Deep-grain surface

Heavier embossing than a standard woodgrain, in the capped construction.

Colours — Three Ranges, and What a Polish Summer Does to a Dark Board

The whole card, and two things about it that matter more in this market than in a milder one.

The full colour card

Capped co-extrusion: Teak, Antique, Redwood, IPE, Light-grey, Walnut.
Classic uncapped: Teak, Redwood, Walnut, Coffee, Chocolate, Ebony.
3D embossing: Teak, Red Wood, Walnut, Chocolate, Light Grey, Dark Grey.

Thirty degrees is no longer unusual, so colour is a specification decision

A dark board in full sun gets genuinely hot underfoot, and colour is the lever — every composite behaves this way, and so does stone. Antique and Light-grey in the capped range, or Light Grey in the 3D embossed range, run noticeably cooler than Walnut, Redwood or Ebony. If the terrace will be crossed barefoot, start at the lighter end and set the expectation with the client before the order rather than after.

Where the greys live

Grey is what Polish clients ask for most often. It is available in the capped co-extrusion range (Antique, Light-grey) and in the 3D embossing range (Light Grey, Dark Grey). So a grey brief is a capped or 3D embossed job and should be priced on that basis — establish it at the first conversation. And the same colour name across two ranges is not the same colour: Walnut in the capped range is not Walnut in the classic.

Two things worth settling before you order

A swatch is an indication, not a match. Screens and print both shift colour, so ask for physical samples in the two or three you have shortlisted — free, you cover the courier, credited in full against your first order. And order the whole job in one batch: pigment goes into the extrusion, so two runs of the same colour will not be identical and a board replaced in year four will not match. Keep spares from the same shipment.

What the Board Is Actually Made Of

Straight from our own catalogue, with nothing rounded up.

60% wood powder, 30% HDPE

The balance of roughly ten per cent is additives — we would rather say that than quote a figure that adds up to a hundred. On the capped range a co-extruded shield wraps a WPC core, and the shield is the wearing layer. That matters here more than anywhere: it is exactly what a steel-edged snow shovel damages. The material can be recycled and reused at end of life.

Sections, with the dimensions on them

Six of the capped sections with board width and thickness: ZSGJ138H23A and ZSGJ138H23C at 138 × 23 mm, ZSGJ138H25 at 138 × 25, ZSGJ140S23 at 140 × 23, ZSGJ140S25 at 140 × 25 and ZSGJ145S30 at 145 × 30. The capped generation runs round chambers rather than the square cells of the classic range — they clear water instead of holding it, and where water freezes in the chamber every winter that is not a detail. Quote the model number back to us and there is no ambiguity.

Surface textures

Four surfaces: H1 straight grain, and H2, H3 and H5 wood grain. Texture and colour are specified separately, so say both when you enquire.

Where Polish Distributors Put It

Three project types that come up again and again in Poland, each with its own specification questions. The photographs are our own installations, not stock images.

Terraces on detached houses

The volume market. Ground that freezes and thaws every year moves, so the deck is framed clear of the soil — you can see the edge fascia and the gap beneath it here — on bases taken below the frost line, or on adjustable pedestals that can be re-levelled.

Over existing concrete

Renovation work: tiles or a pedestal build-up laid over a slab that is already there. No demolition, no new foundation, and the fall the slab already has is taken up in the pedestals.

Steps and level changes

Where a terrace meets a threshold or a slope. Steps are the first place frost heave shows, because a riser that moves is visible in a way a flat deck is not — so the stringers get the same treatment as the frame: below the frost line, or adjustable.

Your Customer's Site May Not Be in Poland

Here is a pattern we see from this market and from almost nowhere else on this site: the company buying the boards and the ground they are laid on are frequently in different countries. Polish contractors work across western and northern Europe, and they buy from Polish suppliers when they do. If that describes any part of your business, it changes what you should be asking us for.

The deck has to satisfy whoever signs it off, not whoever bought it

A terrace built by a Polish crew on a German property is judged by a German client, and very possibly by a German architect. The board is identical. The questions are not.

A German client asks for the Declaration of Performance and will read the profile list on it. A Dutch client asks about the green film and about wind on a raised deck. A Swedish or Norwegian client asks which season the material is for and how the deck behaves in the thaw. Same product, three different conversations, and the one you prepare for should be the one happening at the site rather than the one at your counter.

Tell us the country of the site and we prepare for that market

This is the practical ask. When you enquire, say where the deck is going to be built, not only where it is being delivered. We will put the documentation together for that market — which usually means the DoP for the exact profile, the support spacing in writing, and the slip evidence with the method named rather than just the figure.

It costs us nothing to get that right at the quotation stage, and it is genuinely awkward to fix once a client in another country has asked a question your paperwork does not answer.

The climate advice on this page may not be the climate of the job

Everything further down this page about frost heave, the expansion gap and snow shovels is written for Polish conditions, and it is accurate for them. If the job is elsewhere, read the page written for that market instead — the failure modes genuinely differ.

For a site in Germany the emphasis shifts to winter damp and de-icing salt: the German page. For the Netherlands it is permanent damp, wind uplift and soft ground: the Dutch page. For Sweden it is the thaw rather than the freeze, and a building season that decides when you have to order: the Swedish page. We wrote them separately because the advice really is different, and sending a crew out with the wrong one is worse than sending none.

One batch, several countries, one reputation

A contractor working across borders builds a reputation that travels with them, and so does an inconsistency. If the same crew lays the same colour on a job in Poznań this year and a job near Berlin next year, the client who sees both is the client who notices a batch difference.

Pigment goes into the extrusion, so two production runs of the same colour will not be identical. The way round it is the same as everywhere but it matters more here: buy a colour in one batch, keep the spares with the job rather than on a shelf, and tell us at the first order if a repeat is likely so we schedule the quantity together.

And if the crew is Polish but the paperwork is not

One small thing worth settling early. Our documentation is issued in English — the certificate and the Declaration of Performance come as the notified body issued them, and that is what a German or Dutch client wants to see anyway. What we can prepare around it is the practical layer: the profile data, the support spacing and the installation figures.

If your fitters need those in Polish, ask and we will tell you plainly what we can put together. Agreeing the terminology once — support spacing, covered width, expansion gap, butt joint, double joist — is worth more than translating a document per job, because those are the terms the numbers attach to.

Installation and Accessories

From our own installation guide. Put these figures on the drawing before the frame goes down — most of the failures we see in Europe come from a frame set out to timber habits.

The gaps, and the double joist

5–7 mm between the sides of adjacent boards. About 5 mm between a capped board and a wall. 3–5 mm at butt joints where two board ends meet. Butt joints sit on double joists — each board end gets its own joist, never a shared one, and this is the detail most often missed. Boards fix with stainless or plastic clips; the joist itself can be aluminium, stainless steel or WPC. Set a gutter at the base so water drains rather than ponds — in this climate a deck that holds water is a deck that lifts a board the first hard night.

Accessories, with sizes

Stainless steel start clip, plastic clip, expansion screw, L-shaped corner trim 50 × 50 × 3000 mm, WPC joist 40 × 30 × 3000 mm, aluminium joist 40 × 25 × 2900 mm. Note the aluminium joist is 2900 mm, not 3000 — an easy hundred millimetres to lose when you take off quantities.

Inside the Plant

Our own facility in Sihui, Zhaoqing, Guangdong. Not stock images. Buyers and third-party inspectors are welcome on site.

Extrusion

Lines running the length of the building. Around 2,000 tonnes a month leaves them — roughly 100 containers.

Loading for Nansha or Yantian

Banded and wrapped before it leaves the plant. The test report travels with the goods.

Colours side by side

Worth seeing in the flesh before you choose. A screen or a printed card is an indication; the sample wall is the real thing.

What Owning the Line Gives You

Capacity you can book against

Roughly 2,000 tonnes a month, about 100 containers. What matters to a distributor is not the headline but that a repeat order does not queue behind somebody else's. Send the volume and the date; we answer with a slot, not a hope.

Dies are ours, so sections are ours

We own the moulds and cut them in-house. That is why the schedule runs past a hundred sections rather than a catalogue page — and why we can talk seriously about a market-specific profile.

A test report with every shipment

Goods are checked before despatch and the report travels with them. Routine, not negotiated — and it is what makes a warranty claim a paperwork exercise later instead of an argument.

Certification: What We Hold, and the Exact Scope

Polish specifiers verify, so here is the whole picture including the scope limits — a certificate covering three profiles is not a certificate covering the catalogue. Ask and we send the document itself.

Get the Documents Themselves

Nothing above is a claim you have to take on trust. Tell us which documents your project needs and we will send the PDFs — certificate, Declaration of Performance with the reaction-to-fire class, and the laboratory reports.

What We Do for a Distributor

A first order can be well under a container

Minimum order is 70 m². Well under a full container, and it exists so a new distributor can test a colour, a profile and our paperwork before committing to a 40HQ. Most suppliers at this end of the market quote 1 × FCL and lose the first conversation.

Samples are free

You pay the courier and we credit it in full against your first order. Ask for a sawn sample: the cut end shows whether the cap runs all the way round the section or stops at the sides. Ask for more than one colour while you are at it — see the card above.

A project-specific per-unit quotation

Send the specification and the volume, get a per-unit price rather than a range. We need: profile, colour, quantity in m², discharge port, the country the deck will be built in, and the date it has to be on the ground.

Private label, market-specific sections, testing on your profile

All three are conversations. We own the tooling, we already run sections cut for particular export markets, and where a project needs a test our documents do not cover we will put your profile through the laboratory — fee up front, credited against the order. Every result we send you names the profile it was measured on.

Poland: Route, Transit and Terms

Loading is Nansha or Yantian, both in Guangdong, both within trucking distance of the plant.

What the Polish Climate Does to a Deck

Specific to Poland, and deliberately in a different order from our German and Dutch pages. A Dutch deck fails from damp. A Polish deck fails from the sheer distance between February and July.

The annual swing is the widest of any market we ship to — so the expansion gap is the first thing to get right

A hard Polish January and a hot July are a long way apart, and composite moves more along its length than timber does. That single fact causes more failed decks here than anything else on this page. The image above is the detail that matters: the board ends stop short of the wall on purpose. A board butted tight to a wall or to the next board in winter has nowhere to go in summer, and a buckled deck is a full relay — there is no partial fix. The figures are in the installation section above: about 5 mm to a wall, 3–5 mm at butt joints. Where boards are laid cold, work to the upper end of the range.

Frost goes into the ground here, and the ground lifts

Frost penetration is real in Poland and it is zoned — deeper in the east than on the coast, and your own designer will have the figure for the region. A post base set above that depth lifts, and it lifts unevenly, which telegraphs straight through to the boards. The two answers are a base taken below the frost line, or a free-standing deck on adjustable pedestals that can simply be re-levelled. The composite is not the variable here; the ground is.

Snow, and what gets used to clear it

Snow load on a raised terrace is a structural question for the frame, not for the board — check it with whoever designs the substructure. The part that comes back to you as a complaint is the shovel. A steel-edged shovel dragged across a composite deck scratches the shield, and on a capped board the shield is the wearing layer. Tell your customer to use a plastic blade, as above, and to push rather than chop. It costs nothing to say at the point of sale and it is expensive to argue about afterwards.

De-icing salt attacks the fixings, not the boards

Salt and grit tracked onto a terrace concentrate as the water dries off. The composite handles it. Screws, clips, joist hangers and post bases do not — and that is exactly where nobody looks until the deck has to come up to get at them. Specify the fixing grade properly at quotation, not as an afterthought at the end of the bill.

Polish summers are hot enough that colour is a real decision

Thirty degrees is no longer unusual, and a dark board in full sun gets hot underfoot. Colour is the lever, which is why the card sits near the top of this page. If the surface will be crossed barefoot, specify from the lighter end. We would rather say so before the order than after.

Three Things That Go Wrong When Europeans Import WPC

Not sales copy — these are the three that cost distributors money.

The frame is set out for timber

A joiner spaces joists at whatever timber decking takes, because that is the habit. Composite has a maximum support spacing and it is tighter than timber. Get the figure for your profile in writing and put it on the drawing before the frame goes down. Wrong, and the deck does not collapse — it flexes underfoot permanently, and the fix is lifting the boards.

The end gap gets left out

The most expensive of the three, and in this climate the most likely. The figures are in the installation section above — and the double joist under a butt joint is the half of it people forget.

Batch colour is not matched later

Pigment goes into the extrusion, so two runs of the same colour will not be identical. Order the whole job in one batch and keep spares from it. A board replaced in year four will not match — ours or anybody else's. Distributors who hold a buffer from each shipment avoid the argument entirely.

Warranty, and How a Claim Works

Stepped, not flat

Capped co-extrusion carries 15 years, classic uncapped 10. Both step down by year rather than paying full value throughout: 100% of the value of the affected goods in years 1–3, then 80, 70, 50 and 40% through years 4 to 7, then reducing in bands to 10% in the final years. It covers peeling, cracking and overall uneven fading.

It starts at the destination port

Cover runs from the date the goods arrive and are signed for at the port — not our factory gate, and not the day your customer installs them. That usually works in the distributor's favour.

Certificates are per batch

The schedule that applies is the one on that batch's certificate, which is why the test report shipping with the goods matters. Keep it with the commercial paperwork — and if a consignment is split between jobs in different countries, split the paperwork with it. If a supplier quotes you a flat 25 years, ask for the schedule.

Distributor and project enquiry

Installation Information That Travels With the Crew

For a <strong>composite decking installation</strong> bought in Poland but built elsewhere in Europe, the paperwork must follow the project country, profile and site conditions—not only the buyer's invoice address.

Composite deck installation starts with the actual site

A composite deck installation in Poland, Germany or Sweden can face different drainage, exposure and documentation requirements. Tell us where the work will happen so the profile and supporting information match that site.

Installing composite deck boards across borders

When installing composite deck boards, keep the profile-specific support spacing, perimeter gaps, butt-joint detail and batch documents with the crew. Do not substitute a generic installation sheet from a different section.
