ROBINIO-PREMIUM

ROBINIO Premium Round Poles represents the highest level of precision, technical excellence and harmonious aesthetics – ideal for premium design projects in playground and public space construction.

Processing is fully automated: each robinia log is milled along its natural growth line and simultaneously sanded – resulting in a perfectly rounded profile with a smooth, uniform surface and outstanding dimensional accuracy.
Despite this precision machining, the natural curvature of the robinia trunk remains visible, preserving its organic character while achieving technical clarity.

ROBINIO Premium combines artisan craftsmanship with industrial-grade precision – making it the perfect choice for exposed, high-wear or design-driven outdoor applications.

Consistently graded and quality assured.

Our Products & Solutions

Do you also supply private clients or DIY builders?

Yes, in general – but smaller orders are typically handled by our local distribution partners. We’re happy to put you in touch with the right contact near you.

Do you offer certified playground timber according to DIN EN 1176?

Yes, we do. Our round poles meets all standards of DIN EN 1176 and is supplied sorted, cleaned and free from sharp edges – safe and immediately ready to use for any playground installation.

Are the products delivered kiln-dried or air-dried?

Depending on the application, we supply the appropriate timber in optimal drying quality: for glulam, decking boards or cladding profiles, we use kiln-dried wood (KD) as standard. Our roundwood is sourced exclusively from winter felling to ensure top quality.

Do you supply standardised dimensions or tailor-made sizes?

Both. We offer standard formats as well as customised products – from precision cuts based on drawings to specialised profiles and fixed lengths for playground construction, timber engineering, or the timber trade.

What robinia products are available from ROBINIO?

Our product range includes roundwood, sawn timber, decking boards, laminated timber profiles, fences, plant stakes, posts, seating blocks, and barrel staves. In addition, we also offer selected oak and softwood products for specialised applications in landscape construction and urban furniture.

Material Properties & Sustainable Use

Is robinia wood available with FSC® certification?

Yes – upon request, we supply FSC®-certified products. Many of our partner facilities are also certified, ensuring full traceability throughout the supply chain.

What is the origin of the robinia wood used by ROBINIO?

Our timber comes exclusively from sustainably managed natural forests in Southeastern Europe – never from plantations. To preserve the forest ecosystem, we harvest carefully by hand, primarily during the winter months.

Is robinia wood a genuine alternative to tropical hardwood?

Yes, definitely! Robinia matches the durability of many tropical woods, yet comes from European sources – making it a far more sustainable and eco-friendly choice.

Does robinia wood require chemical wood protection?

No. Robinia’s rich natural tannins provide lasting protection against fungi, insects and rotting – even under permanent exposure to soil and moisture.

How durable is robinia wood in outdoor use?

Robinia wood is classified in durability class 1–2 according to DIN 68364 / EN 350-2, making it one of the most durable hardwoods in Europe. Depending on the application, it lasts 30 to 50 years outdoors – even without chemical treatment.

Maintenance & Material Properties

How does robinia differ from oak or chestnut?

Robinia wood is harder, more elastic, and significantly more resistant to moisture and pest infestation than oak or sweet chestnut. With a fresh density of 930 kg/m³, it surpasses most native hardwoods in both strength and durability.

Is cracking common in robinia timber?

Yes – similar to other hardwoods, robinia may exhibit drying or tension-related cracking, especially in round sections and larger profiles. Such features are typical of the material’s natural behaviour and have no negative impact on its structural performance or longevity.

Does robinia wood change colour when exposed to outdoor conditions?

Fresh robinia wood ranges from yellowish-olive to brown, but when exposed to the elements, it develops a uniform silvery-grey patina. This natural weathering does not affect the wood’s durability or structural integrity.

How much maintenance does robinia wood require?

Robinia timber is notably low in maintenance. It may be left untreated to develop a natural grey patina, or optionally oiled to maintain its original colouring over time.
