This is used to span paved areas around tree roots. The manufacturer, Deep Root, offers extensive specs and info on their site. My concern is for the future deterioration of the galvanized steel tubes in SFL? Do any of my colleagues have experience with this product? I've never specified galvanized structure embedded in SFL compacted fill, seems like this would fail as galvanized metal does not hold up? ken hercenberg Senior Member Username: khercenberg Post Number: 925 Registered: 12-2006 Posted on Tuesday, July 07, 2015 - 04:58 pm:    I would have the same concern. How big are the members? How thick is the steel? What is the expected lifespan?
