Which timber is best for bridges?

Bridges have been constructed from many types of timber, however, certain timber grades are ideally suited to the demands of typical bridge environments, and Douglas Fir is in a class of its own!

Douglas fir is known to be the most robust among softwood varieties and is globally acclaimed for its exceptional strength-to-weight ratio.

The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. Native to western North America, it’s also known as Douglas spruce, Oregon pine, and Columbian pine.

Douglas Fir is ideally suited to decking, rails and posts on Bison Bridge kits where a timber bridge is required. Combined with a galvanised steel structure, Douglas Fir provides an aesthetically pleasing, robust bridge solution.

Why ‘Douglas’?

David Douglas, namesake of Douglas Fir was born in Scotland in 1799. More info here:
