Velocity trampolines are a great new value range of trampolines and are a fantastic first purchase for those that do not want to compromise on safety or quality! Our design brief was to build trampolines suitable for all to use but to represent excellent value for money. Frame Constructed with 1.6mm HOT galvanised top frame, the HOT galvanisation process ensures that the trampoline frame sections are galvanised inside and out. (unlike most other more cheap galvanised frames that are only galvanised on the exterior of the frame) This will ensure the trampoline remains robust for many years and is suitably strong for even the heaviest of users. An extra strong set of T Tube / box joints constructed with 2mm thick coated steel at the top of each leg provides huge strength at what is traditionally the weak point of a trampoline. Springs 72 Galvanised and Zinc plated 165mm High Tension springs. This is the optimum number of springs required to give the maximum bounce across most user weight
