What does robinia wood mean?

Robinia is indigenous to the south-eastern region of the USA. Ranking after eucalyptus and poplar trees, today, the robinia tree is the most frequently cultivated deciduous tree in the world. Predominantly with the goal to improve the soil (high nitrogen levels) and to prevent erosion. Retimbering of stock with the purpose to produce wood exists mainly in south-eastern Europe, largest regions being in Hungary and Romania.
The wood of the robinia tree possesses excellent properties, a high natural resistance and can frequently serve decorative purposes. As a result of a poor shape of the trunk and the small diameter and length, there are currently no large quantities of robinia wood available for normal industrial uses. This will probably not change in the near future - there will be limited supply of robinia wood on the European market.

What are the advantages of laminated robinia wood?

No decay areas, less and substantially smaller shakes:

K&K uses laminated robinia wood because it is a construction material which hardly generates any shakes.

Our laminated robinia wood is manufactured from pre-selected lumber with no defects. The spiral graining, often visible in the shakes, is removed in several constructive stages. The individual lamellas are pre-dried to 12-14% before they are glued and at the same time the especially high tensions characteristic of the robinia wood are eliminated.

For the gluing, the lamellas are placed in such a way that the residual tension in the wood material is virtually eliminated.

Higher bearing strength and increased installation lengths and heights:

Because it consists of dried wood and is composed of multiple layers, the laminated wood also possesses and increased bearing strength of up to 50%. This then allows for higher installation lengths or heights, respectively. Post lengths up to 14 m are possible.

Better surfaces with higher durability:

The integrated industrial production process of the laminated wood, from pre-selection, drying and removal of defects to gluing and circular milling enables us to manufacture a considerably higher surface quality of the material. The circular milled posts are abraded with 240 grain size and furnished with a surface finishing especially developed for this purpose (used for posts and pedestals since May 2009). This improved conditioning (lotus effect) lengthens the life cycle of the wood and the UV-stability of the natural robinia wood colouring. The "greying effect" of the wood surface does not occur.

What is gluelam robinia wood or "gluelam"?

Glued laminated wood in general consists of at least three dried wooden boards or board laminations of  30 to 40 mm, glued together with parallel fibre orientation.
Glued laminated wood is an optimised wood material with improved durability and longevity. Glulam or gluelam are synonyms for glued laminated woods.

What is gluelam Robinia wood?

Laminated robinia wood is composed of pre-dried robinia lamellas. K&K uses six lamellas of approx. 22 mm strength. The product KAROLAM® developed by K&K is a special kind of laminated robinia wood. Laminated wooden boards have been a standard material for surface construction for decades.
The most employed wood type for this purpose is the common spruce,  which is unsuitable for - weather exposed - outdoor areas (without roofing etc.). Therefore we offer our in-house development KAROLAM®.
