Built to Last: Heavy-Duty Trampoline Springs for Endless Fun
When it comes to trampolines, performance and safety start at the springs. Our heavy-duty trampoline springs are engineered to deliver unmatched durability, bounce, and resilience-making every jump smoother, higher, and more enjoyable. Made from high-tensile galvanized steel, these springs are rust-resistant, weather-proof, and designed to withstand years of outdoor use.
Whether it's for backyard fun, fitness training, or trampoline parks, our springs are built to handle high-impact use while ensuring consistent tension and support. Count on reliable quality and endless fun with every bounce-because your trampoline deserves the strength that lasts.
High-Tensile Steel Construction
Manufactured from premium-grade galvanized or stainless steel for superior strength and long-lasting elasticity.
Rust & Corrosion Resistance
Zinc-coated finish or hot-dip galvanization protects the springs from rust and weather damage-even in humid or rainy climates.
Optimized Tension for Maximum Bounce
Precision-engineered coil diameter and length provide excellent tension, delivering a smooth and powerful rebound.
Extended Coil Design
Longer coils enhance energy return, giving jumpers a higher, safer bounce with less impact on joints.
Heavy Load Capacity
Designed to support users of all sizes, making them suitable for kids, adults, and high-weight commercial use.
Secure Hook Ends
Reinforced hook ends ensure a tight, reliable grip on the trampoline frame and mat, preventing slippage or detachment.
Universal Compatibility
Available in standard sizes for easy replacement or upgrades-fits most round, rectangular, and oval trampoline models.
Safety-Tested Performance
Each batch is rigorously tested for stretch, rebound, fatigue resistance, and load-bearing performance.
UV & Weather Resistant
Withstands extreme sun exposure, heat, cold, and moisture-perfect for all-season outdoor trampolines.
Low Maintenance
Durable build reduces the need for frequent replacement, saving time and cost for families and operators.
Wire Diameter:
Range: 3.0 mm - 4.2 mm
Thicker wire increases strength, fatigue resistance, and spring life.
Outer Diameter (OD):
Range: 25 mm - 35 mm
Larger diameters help absorb more force and provide smoother bounce.
Free Length (Unstretched Length):
Range: 120 mm - 210 mm
Determines overall spring tension and bounce capacity.
Total Coils:
Typically: 26 - 34 coils
More coils allow for a more controlled stretch and softer landing.
Material:
Galvanized High-Tensile Steel Wire
Options: ASTM A228 (Music Wire), 65Mn, or stainless steel (for anti-corrosion environments)
Finish / Coating:
Zinc-plated or hot-dip galvanized
Optional: Electroplated, powder-coated, or stainless steel (AISI 304/316)
Hook Style:
Closed-loop hook or double hook
Designed for secure fit and easy installation on frame/mat
Maximum Stretch Length:
Range: 150% - 180% of free length
Defines safe working extension for maximum durability
Load Capacity (per spring):
Range: 30 - 60 kg per spring
A full trampoline uses 60-100 springs, depending on model size
Fatigue Life:
Tested to over 100,000 cycles under normal load
Ensures long-term use without deformation
Extension springs are in our daily life everywhere, small electronics, house appliances, from being in our cars , to the farm machinery that produces our food.
Extension springs make the electronics to function as designed.
Springs are likewise used in washing machines to suspend the drum in position.
extension springs to help the house doors or furnitures close back over once they have been opened.
The most common exercise equipment that use extension springs like the Chest Expander, and other strenght training facilik
1. What material are these springs made from?
Our trampoline springs are made from high-tensile galvanized steel, providing excellent durability, elasticity, and rust resistance. Stainless steel options are also available for coastal or high-humidity environments.
2. How do I know which spring size I need?
Measure your current spring from hook end to hook end (unstretched). Common lengths include 5.5", 6.5", 7", 8.5", and 9". Always match both the length and wire thickness when replacing.
3. Are these springs compatible with all trampolines?
Our springs are designed to fit most round, rectangular, and oval trampolines. For best fit, check your trampoline's user manual or measure your old springs before ordering.
4. How many springs do I need to replace on my trampoline?
We recommend replacing all springs at once to maintain even tension and bounce. Mixing old and new springs can cause uneven wear and unsafe jumping conditions.
5. How long do these springs last?
With proper use, our heavy-duty springs are rated for 100,000+ bounce cycles and can last 3-5 years or longer in outdoor conditions. Longevity depends on usage, load, and climate.
6. Can I use these springs for indoor or gym trampolines?
Yes, our springs can be used for indoor trampolines, fitness rebounders, or professional gym setups-just ensure size and tension requirements match your equipment.
7. What makes these springs "heavy-duty"?
These springs use thicker wire, reinforced hooks, and higher-tensile materials, making them stronger and more resilient than standard trampoline springs. They are built for high-weight capacity, repeated use, and harsh weather.
8. Do the springs come with a warranty?
Yes. We offer a 1-year warranty covering manufacturing defects. Custom warranty terms are available for wholesale and OEM customers.
9. Are custom sizes or packaging available?
Yes! We offer custom spring lengths, hook types, and private-label packaging for bulk or OEM orders. Contact us for detailed specifications.
