Stemwood

Structural sawn timber intended for construction must offer similar guarantees to those offered by other materials and products intended for the structural construction sector. For this purpose, it is necessary to develop classification tools that allow manufacturers and marketers to certify the strength and stiffness values of all the wood that is placed on the market (adjusted to the species and origin that corresponds).
It is, in addition to being a legal obligation, a tool for the valuation of wood that is enabling a competitive improvement of its industrial network.

Technological development of structural sawn timber not only enables it to be directly promoted in the construction sector as a construction element, but also to be incorporated into the manufacture of technological products with high added value, such as glued laminated timber, duos, trios, CLT, prefabricated panels... These are high value-added products that require high levels of competitiveness that cannot be achieved without their main raw material, structural sawn timber, increasing its competitiveness, optimising its manufacturing times and its declared mechanical properties

Visual classification tools have been developed for the main commercial wood species found in Spanish forest stands, such as Pinus sylvestris, Pinus insigne, Pinus nigra, Pinus pinaster, Abies alba, Pseudotsuga menziesii, Quercus rubra, Castanea sativa and Eucalyptus globulus. Tools that in many cases enable the possibility of classifying structural sawn timber into three structural qualities, which allows the different qualities of wood that the timber industry places on the construction market to be classified and valued.
Mechanical classification systems are currently being developed for the main species of the Pinus genus. This is one more step in the competitive improvement of this type of wood, as it improves the classification times and the classifying performance in the different mechanical qualities.
Both developments have enhanced the value of the wood of the different wood species characterized, and have promoted its use in construction.

Many forests that could generate income are not really managed and forest-owners don´t take care of them. The causes are very often the low profitability of wood exploitation and the complexity of its management. Forest owners are not usually specialists and are not engaged in forestry activities. This leads to no incomes and to an increased risk of fires and pests. Faced with this situation, Agresta proposes specific contracts to forest-owners, making it possible a professional sustainable management allowing revenues, forest planning, wood mobilization, and infrastructure and silvicultural operations.

Forest management is not enough to get many forests out of abandonment. It is important to be in contact with main stakeholders and the reality of the markets, something that a forestry company can assure.
It is necessary to work with professionalism, entrepreneurial vision and long-term commitment, in a collaborative relationship and win-win with the owner.
The specialization in turnkey forest management by a company allows improving and making profitable the management since it increases the innovation capacity, including the technological one (management software, forest inventories with remote sensing...)
