Douglas Fir

Douglas Fir timbers are best known for their tough fiber, dense grain structure and strength. They are additionally valuable for their rustic beauty and has excellent fire ratings in the model building codes. The Douglas Fir Lumbers are  naturally dimensionally stable and universally recognized for its superior strength-to-weight ratio and also having the ability to season well in position.

Douglas Fir is the first choice of Architects and Engineers, who look for the best in structural lumber, Its high specific gravity provides excellent nail and plate-holding ability.

Working Properties

Douglas Fir dries easily and rapidly, with little tendency to check and with good dimensional stability. It machines reasonably well, has excellent turning properties, glues well and has moderate nail and screw holding ability. It can be stained or painted to a very good finish.
