Decking and timber for outdoors
We produce decking, cladding boards and other timber for outdoor use at the Drewno Pilarscy S.C. sawmill in Sulęcin (Lubusz Voivodeship, Poland).

Boards are planed on four sides and profiled. Our decking has a grooved profile on both faces: the upper one is fine and smooth and gives grip underfoot, the lower one drains water, extends the life of the board and stabilises its width. We supply the boards raw, without impregnation.
We do not compete with DIY-store products on price or on quality. You will not find a 19 mm board here, that is not our category. We work above 24 mm, and after machining we also get elements from 30 and 40 mm up. Widths are non-standard too: our boards are 145 and 155 mm, with 160 mm made on request.
The same category covers tongue-and-groove cladding boards, interior wall boards in ash and oak, exterior lamellas for self-assembly (the kind we make for saunas) and narrow lamellas to order. We also make one-off items that need a tongue-and-groove profile, a barn door for instance.
Dimensions and lengths are set per order. We also make matching joists, so the whole structure comes from one source.

Questions about decking and timber for outdoors
Are the boards impregnated?+
No, we supply the boards raw. We no longer handle impregnation or installation, but we will advise what to protect the wood with and point you to a contractor if one is needed.
Can you supply the substructure?+
Yes. We also make joists, so the board and the structure beneath can come from one order.
How does your board differ from a DIY-store one?+
In thickness and finish. There is no 19 mm board here, that is a DIY-store product. We work above 24 mm, and at 24-26 mm for tongue and groove, with the rebate and chamfer cut in an unusual way. There is also the safety side: the upper grooving is anti-slip, and when laying the surface we can cut unusual geometric patterns.
