MaxAir Trampolines constructs our 6×12 rectangular trampoline frame from hi-strength steel with a wiggle wire designed specifically for spring attachment. This special form reduces friction and keeps our springs firmly in place. We treat each frame with a special powder coating which provides great protection from rust and wear. Our frames come in multiple pieces for ease of shipping, handling, and installation. Each design element of our frame contributes to their longevity and makes installation straightforward and easier than thought possible.
