Farm, equestrian, vineyard or decorative: which robinia fence for which use, how deep to set the stakes, and what cleft paling is worth.

Why a 6-8 cm round stake rots in 3 to 10 years, what sapwood really changes, and which cut to choose for each use: round, sawn, split or square.

End post diameter, line post spacing, 1.8 m vine stakes: the dimensions of a robinia trellis and how it stands up to the grape harvester.

Planning rules, post anchoring, spans up to 6 m, diameters and quantities: the guide to robinia pergolas, with standard plans.

Finger-jointed robinia decking and cladding: use class 4 without treatment, 88 N/mm² to EN 408 (UCLouvain), profiles, sizes and installation.

Ten-year plans, numbered trees, a hammer with the status of a seal, SUMAL 2.0 and the EUDR 2026: how Romanian timber is traced, and what to ask your supplier for.

FSC® chain-of-custody certified (licence C153588, SGSCH-COC-011793), FSC® 100 % on request, ISO 9001:2015: what our labels guarantee and how to check them on info.fsc.org.

Pressure-treated pine against naturally durable robinia: service life in the ground (10 vs up to 30 years), chemicals, end of life, cost per year. An honest comparison.

Sawn, quarter-sawn robinia shingles: a use class 4 wooden tile without treatment, ventilated overlapping installation, for roofs, façades and shelters.

Clear-cuts of 3 ha maximum, felling with the sap down (15 September – 15 March), brash windrows and regrowth by root suckering: how Romanian robinia is harvested.

EN 350 durability, stake service life, density, hardness, tannins, price: an honest comparison of robinia and sweet chestnut outdoors.

Ipe class 1 vs robinia class 1-2: durability, price, CITES, the EUDR and transport – an honest comparison of tropical and European robinia decking.

Service life, heat in the sun, scratches, end of life and price: an honest comparison of WPC composite decking and solid use class 4 robinia.

EN 350 durability class 1-2, trials in Belgium, Germany and New Zealand, and our experience: how long a robinia stake really lasts, and why.

≈ 18 GJ/t oven-dry, 14.4 GJ/t net at 20 %, long embers, fast seasoning, and why it burns even fresh: robinia (acacia) as firewood.

Why robinia costs what it does: 25-30 years of growth, strict sorting, sapwood removal, a quarter of the tree sold – compared with pine, ipe and WPC.

Durable in ground contact with no treatment: robinia for vegetable gardens, raised beds, edging, retaining walls and steps – toxicity, liners, service life.

No treatment, 1.3 t of CO₂ stored per m³, regeneration by root suckers, an introduced species: an honest look at robinia's environmental record.

Robinia's greying is a patina less than half a millimetre deep: durability is unaffected. Decking oil, wood reviver, cleaning — and what is pointless.

Acidic (pH 4.5), dense (0.70–0.90 t/m³) timber: A2/A4 stainless or C4-coated hardened steel, pilot holes at 70 % of diameter, through bolts. Sizes and spacings.
