What Are Trampoline Springs Made Of: Getting to Know Your Trampoline
When buying a trampoline, one of the main features you'll focus on is the quality of the bounce, and perhaps the most defining factor of this result can be attributed to the quality of springs that come along with your trampoline. Just to clarify, there are other factors that can influence the quality of bounce such as the shape of the trampoline, jump mat materials, and even whether or not the trampoline is on even ground.
In this article, we'll not only look to answer the question "What are trampoline springs made of?", but we'll also look at the different types of spring systems commonly found on modern-day trampolines, the benefits of each system, and, of course, their construction.
Types of Trampoline Springs
Firstly, it's important to understand that there are two different types of spring system that are commonly used on trampolines today, and these are as follows:
Metal springs are by far the most conventional spring system when it comes to trampolines. They are mainly favored for their durability and length of life as they are, more often than not, constructed from steel. This allows them to put up with heavy use and even allows for a higher maximum load weight.
With the vast majority of outdoor trampolines using metal springs, it's important to make sure that they are galvanized. This is the process of covering the spring in a protective zinc layer; this will significantly reduce the rate at which your springs begin to encounter rust and will typically last decades. Most springs will specify if they are galvanized or not so keep an eye out for this.
- Springs are all individually attached to the frame, so if one breaks, it is easily removed and then replaced.
- Metal springs are extremely durable and can last through years of use before replacements need to be considered.
- The metal is inherently UV resistant, preventing any damage to them in sunny climates.
- Metal springs can be wound to a higher tension than elastic springs creating an all-around superior and more consistent bounce.
There are two different types of elastic spring system currently available, and they are bungee cords and tension bands. Both are made from a synthetic elastic, but tension bands are straps that are around two inches thick, whereas bungee cords are elasticated ropes. In regard to performance, they both deliver extremely similar results, and both operate at a quieter level than their metal spring counterparts.
- These are safer as users no longer need to worry about getting their feet or legs caught between a metal spring and the trampoline frame.
- Significantly quieter use which allows the trampolines to be used indoors without disturbing those nearby.
- These are typically cheaper to replace when compared to metal springs.
- Elastic springs are impervious to rust, so they don't require regular cleaning or treatment.
When you own a trampoline, it is just a matter of time until you have to replace a spring whether it be metal or elastic. Hence, you should get used to how the spring system operates and how to remove and reattach springs without difficulty.
1. The Number of Springs
As a rule of the thumb, the more springs you have and the longer the springs are, the more bounce is created by the jumper. This principle follows Newton's Third Law of Physics in that "every action has an equal and opposite reaction." This states that the force used to extend the spring is proportional to the length of the extension, so increasing the number and length of springs deliver a greater bounce.
2. Shape of Springs
There are really two types of springs that you'll come across when looking at trampolines, non-tapered or dual-tapered. While dual-tapered springs are typically more expensive than their non-tapered counterparts, they do deliver higher performance. This is due to them offering a great deal more lateral stability, meaning, less shaking and a smoother stretch.
3. Correctly Assembling Springs
Making sure that your trampoline springs are correctly aligned and fastened is extremely important that is why below, we've created a brief step-by-step guide to get you through it as efficiently as possible.
- Spread the jump mat out and center with the frame opening.
- Insert a spring, hook side down, into the trampolines spring loops and connect the other end to the frame.
- Repeat step number two but on the opposite side of the jump mat
You'll essentially want to make sure you're always attaching opposite springs as you work your way around the jump mat.
So, to answer the question "What are trampoline springs made of?", there are a variety of spring types available and each of which offers unique benefits to the user. Thus, take some time to decide on what type of trampoline best suits your needs as this will more than likely decide on the type of springs that you'll be using.
