Effect of preservative treatment on mechanical performance of round and square poles made of small diameter Scots pine
2012 - IRG/WP 12-40612
A growing proportion of harvested Scots pine (Pinus sylvestris L.) timber originates from the first or second commercial thinning stands. There is a need to find economically viable and high quality wood products that can be manufactured from this raw material. Small log volume means not only demands of increased efficiency for material handling in logistics and manufacturing processes, but also c...

A growing proportion of harvested timber originates from the first or second commercial thinning stands in Finland, which means smaller average log volumes in comparison to final felling stands. Smaller log volume means challenging wood properties such as higher proportion of juvenile wood and sapwood. Due to these facts, products made of small diameter logs are prone to twist and check, and have ...
