【Security Certification&No-gap Design】Zupapa trampolines are tested for safety and durability to exceed all ASTM and TUV standards. The patented(No.:2021214143542) No-gap design greatly reduce hazards of getting your hands or feet caught into the gaps cause the jumping mat and spring cover are tightly sewn together, which even expandes the jumping area . What’s more, the springs are all covered with thick and durable pad. Jump without hazards on Zupapa trampolines! 【Outward Sloping Legs & Full-area Touchdown Design】To further improve the stability of the trampoline , Zupapa trampolines(Patented No.:D991386) adopt outward sloping legs according to the principle of mechanics. And each leg adopts a full-area touchdown design, more stable than the two-point touchdown design.All frames are made of steel tubes of 42mm diameter and a 1.5mm wall thickness (the highest standard in the market), making the whole trampoline extremely sturdy. 【Hot-dip Galvanizing Technology & Heavy-duty Frame】Zupapa trampolines use the latest hot-dip galvanizing technology to make the frame anti-corrosive (anti-corrosive time is 5 times that of ordinary galvanizing methods), more stable and durable. What's more our 1.5mm steel frame tubes comparing with 1.0mm ordinary frame make the trampoline more sturdy,plus wind stakes,the trampoline stands stably even in storm. The static load capacity is 1500 LBS, and the dynamic load capacity: 425 LBS. 【Double Quantity & Curved Net Poles】The outwardly curved net poles are far away from the enclosure net. No afraid of any collision cause there is no risk of hitting to the hard net poles. Each leg is connected to a net pole, and the number ofour net poles is twice that of a traditional trampoline! Let the little jumpers jump as much as they want without worrying about safety! 【More Springs & Impressive bounce】 As we all know springs are the core of the trampoline, we have 12 more hot-dip galvanizing springs to offer impressive bounce.(7inch for 12&14&15&16ft, 5.5inch for 8&10ft) 100,000 jumps provides greater bounce and more weight capacity. 6ft high enclosure net (made of environmental PE) ensures absolute safety and fastness when jumping. The net poles are padded with 10mm foam, can protect your kids from banging against the steel pole.zupapa has been working for decades to provide the safest trampoline with the high-quality materials. 【Unbeatable Guarantee 】Don't forget our unbeatable guarantee: 10 Years for Frame, 2 Years for Jumping Mat & Safety Pad & Enclosure Net & Springs, and free replacement for other parts. We are committed to providing double protection for your purchase. Why Choose Zupapa? Zupapa 2023 Trampoline employs a new structure makes the trampoline more stable and safer, including curved net poles , rectangular structure poles and legs, outward sloping legs ,full-area touchdown legs. Also employs upgraded techniques and technology to make products have a longer life. Hot-dip galvanizing process makes the Zupapa trampoline frame and net pole last for decades. UV absorber uv-9 was added to material, pad, mat and net, to extend the trial life. What's Hot-dip galvanization? Hot-dip galvanization is a form of galvanization which makes the rust resistant time 5 times longer than common galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the air, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances.
