We’ll produce, dry, plane, sand and grind the material for larch bridges, bridges, footbridges and other water structures. Of course, the lumber comes with a certificate for larch construction lumber.
WHAT MATERIAL FOR LARCH BRIDGES, FOOTBRIDGES CAN WE PRODUCE FOR YOU DEPENDING ON THE PURPOSE OF USE?
Freshly sawn (tarred) larch sawn timber with unspecified moisture content
The disadvantage of using unprocessed lumber may be the high water content and the subsequent volume changes and deformation when drying to equilibrium moisture content. The higher water content may also be problematic in terms of increased risk of attack by wood-boring insects, moulds and fungi, but this is to a small extent in oak, as larch is resistant to such attack.
When buying raw material, it is a good idea to choose the right quality for the application. In general, centre sawn timber, ideally radial with no pith content, will be the strongest and most stable.
On the other hand, the incorporation of elements made of uncured wood containing pith can cause undesirable effects in the form of twisting, drying cracks, etc.
This product of basic sawmill processing does not lose its popularity in traditional carpentry constructions, where a relatively wide range of cross-section dimensions is applied – exterior constructions, larch planks in the garden, raised beds and other

Technically dried, planed material for larch bridges, footbridges
The profiles are made of technically dried larch lumber with guaranteed moisture content (exterior usually 15% ±3%, interior 10% ±2%). The central lumber, ideally radial without pith content, will be the strongest and most stable, and care is taken to cut the pith (centre of the log) during the primary cutting of the log. This ensures greater dimensional stability.
Four-sided planing or sanding and chamfered edges are a matter of course for self-dried boards, battens, planks or beams.
For the production of larch timber, logs are used in the order of the first and second pieces from the bottom of the tree with fewer cut branches (knots) and minimal curvature.
