Final decision on wood
Search for best cost/perfomrance ratio

After thorough considerations of various pros and cons we finally decided to use Quinilla (also known as Peruvian Cherry) for the construction of pylons and bridge deck.

Out of all locally available wood species it is the most commonly used in construction business. Therefore it is not expensive and easy to get. Although there are even harder kinds of timber, durability is judged as adequate and its strength is very high.

Peruvian CherryThe reddish-brown lumber has a hardness of 3.190 on the so-called Janka Index. This is twice as much as the North American Maple has. Despite this hardness it is still moderately easy to work with and most important very resistant to biological attacks.

Its basic specific gravity is 0.85 and its overall characteristics make this wood widely used for crossbeams, bridge pieces or in heavy construction.

In regard to sustainability this seems to be the wood one can most easily afford and work with even without high-standard woodworking tools or equipment. This way, minor repairs will be possible without much effort.
