Treehouse Screws, Bolts, and Parts are exposed to permanent alternating loads (wind fluctuation and dancing people) – stainless steel would be too brittle for such loads in the long run with our GTS Screws.
Here, our special steel alloys offer the optimal compromise between elasticity and strength.
Rust does not play a role with the coated screws, as they are oversized and the tree keeps rolling around them. By the time such a screw rusts through, it has long since completely disappeared into the tree ;)
Stainless steel is suitable for the smaller “GTS Free” and “GTS Safety” because the load is lower.
