Explore our primary export-grade trampolines, precision-engineered for commercial park installations, e-commerce brands, and international distributors.
Why Commercial Park Operators and Professional Gymnasts Specify Square and Rectangular Geometry Over Traditional Round Trampolines.
Unlike round trampolines where all perimeter springs pull simultaneously toward a single center point (creating a bowl-shaped deflection), square and rectangular trampolines establish independent axial deflection zones. Spring groups along the length and width stretch independently, providing a predictable, vertical lift trajectory across the entire jump surface.
In commercial trampoline parks and compact urban residential yards, space utilization is vital. Square trampolines yield a 100% usable surface area ratio within rectangular boundaries, eliminating the dead corner space inherent to round equipment. This maximises jump zones for multi-user commercial installations.
Square structures experience high torsional stress at 90-degree frame corners. Zhejiang Lingsha Technology (Funjump) solves frame fatigue through heavy-gauge cold-rolled T-sockets and corner brace gussets, distributing kinetic load smoothly into vertical leg assemblies without structural deflection.
Operating under the global brand Funjump, we are a leading custom trampoline OEM/ODM factory equipped with automated manufacturing lines and a dedicated safety testing facility.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) is committed to producing safe, stable, and highly durable trampolines tailored for global markets. We customize high-quality trampolines for indoor and outdoor environments, adult athletic training, child recreation, and commercial fitness centers. Our facility complies with international quality standards including ISO9001, BSCI, GS, EN71-14, ASTM, and AS4989. With localized quality assurance inspectors and an on-site mechanical laboratory, every batch is systematically tested to eliminate defects prior to shipment.
Advancing Next-Gen Recreational Hardware Through Smart Materials, Robotics, and Ergonomic Assembly Systems.
Future square trampoline frames demand higher tensile strength without adding unwieldy weight. We are integrating advanced micro-alloy hot-dip galvanized steel tubes treated with electro-phoretic rust barriers. This achieves 500+ hours of continuous salt-spray corrosion resistance, perfect for humid coastal climates.
Historically, square trampoline assembly was labor-intensive due to precise alignment requirements. Our R&D team has engineered zero-tool snap-lock frame joints and foldable fitness trampolines. This allows residential customers and commercial staff to set up or dismantle equipment in under 15 minutes while preserving full frame rigidity.
By leveraging high-density Polypropylene (PP) fabrics woven with UV-inhibiting carbon monofilaments, our mats exhibit zero elasticity degradation across 8-row precision cross-stitching. This mitigates center-sag and guarantees consistent spring rebound energy transfer.
Direct feedback integration, user-centric product iterations, and scalable fulfillment solutions for cross-border B2B trade.
We actively incorporate customer feedback into our product lifecycle. For example, traditional trampolines presented storage and setup challenges because balancing ease of assembly with structural stability requires specialized connectors. Through intensive engineering, our technical team created quick-fold fitness rebounders and mini indoor trampolines requiring zero tools, receiving wide acclaim from overseas importers.
We maintain long-term OEM/ODM contracts with major international trading firms and e-commerce leaders on Amazon, where our partners consistently rank in the top category tiers. At Zhejiang Lingsha Technology Co., Ltd., our brand core "Funjump" embodies our mission: allowing every child and adult to enjoy secure, joyful, and athletic recreation at their fingertips.
