Product Introduction
The trampoline tension spring is the core elastic component connecting the jumping mat and the rigid frame. Its performance directly determines the trampoline's bounce height, cushioning, safety, and durability .
We specialize in providing high-performance tension spring solutions for all types of trampolines. Whether for backyard recreation, continuous high-intensity use in commercial trampoline parks, or professional competitive training, we offer reliable products, from standard parts to customized solutions, thanks to our deep understanding of materials, processes, and fatigue life.
Product Parameters

project |
Core parameters |
|
Material |
High-carbon spring steel : It has excellent elasticity and fatigue resistance, and is cost-effective, making it a universal and reliable choice for residential trampolines. |
|
Galvanized spring steel : Based on high-quality spring steel, a galvanized layer is added to provide reliable rust protection. It is specially designed to cope with outdoor humid and rainy environments and extend its service life. |
|
|
wire diameter and size |
Wire diameter range : commonly used is 3.0mm - 8.0mm, and can be customized according to load and bounce requirements. |
|
Craftsmanship and Design |
Precision winding : ensures uniform coil and consistent stress. |
|
Surface treatment |
The default treatments include oil immersion for rust prevention , galvanizing (electroplated or hot-dip galvanized), and powder coating . In addition to rust prevention, black and blue colors are also available to coordinate with the overall color scheme of the trampoline. |
|
Key performance |
Tensile force , elastic stiffness , maximum safe tensile length , and fatigue life (usually requiring tens of thousands of cycles) can all be designed and verified according to the application scenario. |
Product Advantages
We are committed to providing trampoline springs that not only meet standards but also withstand long-term testing.
1. Flexible customization and service support
We support small orders and offer custom design services, including non-standard sizes, special hook types, surface colors, and packaging (such as logo customization), to meet your needs at all stages from trial production to mass production.
2. Materials and processes designed for long service life
• By optimizing the elastic limit and toughness of the material through precise heat treatment processes, the spring can maintain excellent performance and resist fatigue degradation even after tens of thousands of stretching cycles.
• Offers targeted options of high-carbon steel and galvanized steel to ensure a perfect match between materials and the environment (indoor/outdoor), guaranteeing durability from the source.
3. Enhanced hook-type safety design
The spring ends feature a hook-shaped design with increased curvature, which creates a more secure engagement with the connection points of the trampoline frame and the jumping mat, providing excellent holding force and effectively preventing accidental detachment during vigorous jumping, thus ensuring user safety.
4. The drum-shaped structure provides a better bouncing experience.
Compared to ordinary cylindrical springs, our mid-section drum-shaped design offers better elastic deformation capacity and a longer cushioning stroke during stretching. This means it can store and release more energy, providing users with a more powerful, softer, and more responsive bounce.
Main Application Scenarios
Our tension springs serve different levels of the trampoline market:
Residential and backyard trampolines: Providing families with a safe, durable, and cost-effective bouncy experience, with a focus on rust prevention and long-term stability.
Commercial trampoline parks: Designed for continuous, high-frequency, and high-load operation scenarios, the springs must have extremely long fatigue life and excellent consistency to maximize operational efficiency and safety.
Professional training and competitive trampolines: meeting athletes' ultimate requirements for rebound accuracy, response speed, and dynamic curve.
We understand that a reliable spring is the cornerstone of trampoline safety and enjoyment. If you are looking for a trampoline spring supplier or need to optimize your existing solution, please feel free to contact us with your specific specifications or scenario description, and we will provide you with professional product advice.
