Lingsha
Factory-direct wholesale items engineered for maximum durability, structural stability, and superior safety compliance.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) operates at the forefront of modern sporting goods engineering. Dedicated to developing ultra-safe, high-performance, and structural sound outdoor rectangular trampolines, our manufacturing infrastructure serves premier international brands, commercial jump parks, and global retail chains across Europe, North America, and Australia.
Spanning over 68,000 square meters of state-of-the-art production area, our facility leverages fully automated robotic pipe bending, precision laser welding, and automated heavy-duty sewing lines. Coupled with an in-house specialized trampoline safety testing lab and professional quality inspectors, we rigorously test tensile strain, UV degradation, salt-spray rust resilience, and impact resistance to weed out defective items long before dispatch.
Understanding the structural physics, spring recoil vectors, and space utilization benefits that make custom rectangular models the preferred choice for commercial and professional markets.
Unlike round trampolines where all springs pull simultaneously toward the center—forcing the jumper toward the middle—rectangular designs feature criss-cross spring orientations. Each side acts independently, giving jumpers predictable, vertical thrust vectoring across the entire jumping surface.
Rectangular outdoor trampolines integrate seamlessly into contemporary residential landscaping and urban yards. They fit neatly alongside boundary fences, patio edges, and swimming pools without wasting dead space, maximizing usable square footage in commercial venues and private gardens alike.
Our factory utilizes cold-rolled heavy-gauge galvanized steel tubing (up to 2.5mm wall thickness). Rectangular frame geometry distributes localized impact energy across longitudinal structural beams, mitigating frame twisting and flexing under high-load gymnastic stress.
| Feature Parameter | Funjump Custom Rectangular Series | Standard Round Trampolines | B2B Advantage & Value Gain |
|---|---|---|---|
| Bounce Vector Dynamics | Uniform, non-directional bounce zone | Center-converging force pull | Essential for athletic gymnastics & acrobat training |
| Frame Steel Specs | Hot-dip internal & external galvanization (2.0 - 2.5mm) | Standard single-sided coating (1.2 - 1.5mm) | 10+ years anti-corrosion life in coastal marine environments |
| Spring Mechanics | Tapered high-tensile 210mm piano wire springs | Standard cylindrical 140mm zinc springs | Deeper displacement, smoother kinetic deceleration |
| Yard Footprint Utilization | 95% linear boundary matching | 65% boundary fitting (high corner dead-space) | High customer satisfaction for residential landscapers |
Pioneering smart kinetic feedback systems, sustainable polymer mat weaves, and tool-free quick assembly frameworks.
Our R&D team has engineered a 260g/m² Permatron PP woven mat infused with carbon-black UV stabilizers and anti-microbial treatments. Rated for over 5,000 hours of continuous direct UV exposure without tensile degradation.
Integrating optional IoT sensor clips embedded beneath the frame perimeter to record real-time jumper velocity, G-force impact metrics, and fatigue cycle tracking for commercial jump parks and athletic performance centers.
Solving the industry-wide pain point of complex customer assembly. Our patented self-locking T-connectors allow frame assembly without power tools or complex bolt sequences, cutting setup time by over 60%.
Complete end-to-end transparency. Inspect our automated metalworking, high-density sewing, precision packaging, and specialized QC lab setup.
Equipped with CNC automated tube benders, robotic laser cutters, and multi-axis hydraulic punching units to guarantee seamless frame joints and zero sharp burrs.
Using 8-row reinforced V-ring stitching tech and UV-resistant poly-thread to lock in safety nets and spring safety pad covers against heavy tear stresses.
Every production batch undergoes dynamic drop tests, static weight overloading up to 5x nominal capacity, salt-spray corrosion chamber aging, and net tear resistance.
Flexible OEM/ODM engineering, container load optimization, private branding, and turnkey commercial solutions for global distributors.
We offer 1-box and 2-box mail-order packaging compliant with ISTA-6A drop testing standards. Includes high-density foam edge guards and reinforced 5-ply corrugated master cartons engineered to withstand courier transit without product damage.
Heavy-duty, high-capacity rectangular trampoline units customized for trampoline parks, resort play areas, and sports training academies. Option for thick 30mm vinyl safety padding and specialized performance springs.
Custom silk-screened logo printing on jumping mats and safety pads, custom frame powder-coating colors (matte black, ocean blue, neon green), and bespoke retail box artwork created by our in-house graphics engineering team.

Technical details, order minimums, manufacturing lead times, warranty terms, and export logistics.
A: We are a direct manufacturing factory (Zhejiang Lingsha Technology Co., Ltd. / Funjump Brand). Our facility spans over 68,000 square meters in Zhejiang, China, housing specialized metalworking, sewing, and assembly workshops along with an advanced testing laboratory.
A: We support standard trade terms including Ex Works (EXW), FOB Ningbo / Shanghai, and CIF destination ports. Standard payment terms are T/T (30% deposit prior to production, 70% balance paid against Bill of Lading copy). Irrevocable L/C at sight is also accepted for large volume orders.
A: During Peak Season (November to June), mass production delivery takes approximately 35 to 55 days. During Off Season (July to October), lead times range from 10 to 35 days depending on batch customization complexity.
A: Our standard MOQ is 50 sets per single size/model. Sample orders for engineering validation and quality audits are welcomed and can be prepared rapidly upon request.
A: Yes, sample units can be produced for buyer verification. While sample creation costs can be offset against bulk orders, the client is responsible for logistics freight expenses.
A: We offer a 1-year comprehensive factory warranty on steel structural frames, jumping mats, and safety net components. Warranty policy covers material defects under normal intended usage.
