I’ve been asked to make the slats for an outdoor bench. It will be placed in a park in memory of a friend who passed away. The organization we were part of is having a local metalworker make the end frames, so I would just be making simple slats that will be fixed to the frames with fasteners. This in Central California near the coast and will be in full sun.
In general I prefer to use American woods, primarily because I believe forests in America are more likely to be sustainably managed. I know teak is usually the first recommendation for outdoor furniture, but I’m thinking about using white oak.
Any other American woods I should consider?
Any feedback on imported lumber that has strong tracking/verification of sustainable harvest practices?
I’m thinking of using 5/4 lumber for a 50” span. The sagulator makes me think this should be fine unless two football players sit on it at the same time.
