Explore our export-ready, certified trampoline models built with high-tensile galvanized frames and UV-resistant jumping mats.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) operates at the forefront of sports equipment engineering and trampoline safety design.
Zhejiang Lingsha Technology Co., Ltd. (brand standard: Funjump) is committed to producing exceptionally safe, structurally sound, and high-performance trampolines. We custom engineer a full spectrum of high-grade recreational and professional bounce hardware tailored for international market demands. Our product matrix spans indoor and outdoor residential trampolines, toddler safety bounce setups, commercial adult fitness rebounders, and feature-rich backyard systems.
Operating out of our expansive 68,000 square meter standardized industrial park, our facilities integrate automated robotic metal fabrication, automated precision textile stitching, and continuous quality assurance pipelines. Powered by a workforce of over 100 dedicated technical specialists and automated production equipment, our daily manufacturing throughput exceeds 1,500 complete trampoline sets.
To support global supply chains, e-commerce enterprise fulfillment (such as tier-1 Amazon storefront sellers), and global big-box retail compliance, Zhejiang Lingsha Technology Co., Ltd. maintains strict quality management systems verified by accredited third-party international testing authorities.
Our integrated management and product compliance portfolio includes:
Every batch of raw materials—from hot-dip galvanized steel tubes to high-tensile PP mats—undergoes internal destructive testing in our specialized on-site safety laboratory prior to mass assembly.
Addressing supply chain friction, freight optimization, and risk mitigation for international B2B buyer channels.
E-commerce sellers face stringent packaging regulations (ISTA 6-Amazon.com testing), high return rates due to missing parts or complex assembly, and strict review thresholds. Funjump offers tailored OEM e-commerce solutions including mail-order drop-test approved packaging, toolless quick-assembly hardware, and zero-defect kitting systems. We empower our Amazon partners to achieve #1 Best-Seller status in outdoor sports categories through consistent product reliability.
Mass retailers demand competitive unit costs, robust social compliance (BSCI/SMETA), high volume seasonal capacity, and strict delivery timelines. With our 68,000m² manufacturing footprint and daily output of 1,500+ sets, Funjump guarantees container load optimization (FCL), automated barcode labeling, EDI integration capability, and scalable volume output to meet peak spring/summer promotional cycles without supply delays.
Commercial users require extreme durability, enhanced fatigue resistance, and higher maximum load ratings. Our commercial-grade rebounders and heavy-duty rectangular trampolines utilize extra-thick frame wall steel, heavy-gauge waist-drum springs, and reinforced high-density jump webbing to withstand intense daily operational wear.
Continuous innovation solving traditional user pain points: Structural assembly complexity and dynamic fatigue failure.
Traditional backyard trampolines frequently draw consumer complaints regarding long assembly times (often 2–3 hours) and difficult dismantling for seasonal storage. Funjump’s R&D engineering team successfully solved this design paradox through our proprietary locking connector geometry and foldable frame mechanisms.
By engineering high-strength precision joints, our latest mini fitness rebounders and backyard trampolines facilitate rapid setup and breakdown with minimal or no tools required. This technological improvement preserves absolute frame stability under heavy dynamic load while dramatically lowering consumer assembly frustration and customer service inquiry rates for retail brand owners.
The structural foundation of a Funjump trampoline relies on double-sided hot-dip galvanized steel tubing. The internal and external surfaces of our steel tubes are processed with a 120g/m² zinc coating layer to guarantee resistance to rust, oxidation, and humidity.
Our heavy-duty frames feature wall thicknesses ranging from 1.4mm up to 2.0mm+, coupled with reinforced T-sockets or curved pole connection points. This prevents frame twisting, joint degradation, and structural deformation over long-term outdoor exposure.
| Engineering Component | Funjump Standard Specifications | Industry Average Baseline | Operational Value Delivered |
|---|---|---|---|
| Steel Frame Tubing | Hot-Dip Galvanized Inside & Out (1.5mm - 2.0mm) | Single-sided Cold Galvanized (1.0mm - 1.2mm) | Prevents structural rust-through & frame collapse under shock load. |
| Jumping Mat Fabric | 260g/m² High-Density UV-Proof Permatron PP | 180g - 220g Standard PP Polypropylene | Extends sun exposure life to 5000+ UV hours; prevents tear-outs. |
| Perimeter Stitching | 8-Row Heavy-Duty Reinforced Sewing with UV Thread | 4 to 6 Rows Standard Thread | Distributes tension evenly; eliminates spring V-ring pullout risk. |
| Spring Metallurgy | High-Tensile Galvanized Tapered Waist-Drum Springs | Straight Cylindrical Light Wire Springs | Provides superior kinetic bounce response & fatigue resistance. |
| Safety Enclosure Netting | 110g/m² High-Density PE Netting with Curved Poles | 70g - 90g Standard Netting with Straight Poles | Prevents user-pole contact; high impact absorption without tears. |
Take an insider look at our modern manufacturing environment, automated workshops, and stringent quality control checkpoints.
Our 68,000m² facility divides into dedicated single-purpose workshops to optimize manufacturing workflow, eliminate cross-contamination of material flaws, and maintain high throughput speed. View real scenes from our modern metalworking, sewing, packaging, and finished warehousing lines below:
To eliminate shipping defective units overseas, Zhejiang Lingsha Technology Co., Ltd. staffs full-time specialized inspectors and maintains an advanced quality testing lab. Products are selected at random from production lines to undergo mandatory stress and environmental resilience tests:
Mitigating regional regulatory hurdles for seamless market entry in North America, Europe, Oceania, and Asia-Pacific.
Trampolines destined for the United States and Canada must comply with ASTM F381-16 (Standard Safety Specification for Components, Assembly, Use, and Labeling of Consumer Trampolines) and ASTM F2225-15 (Enclosure Safety Systems). Funjump products are factory-verified to include warning placards, zero-gap enclosure netting, and mandatory structural shock absorption tests.
For European buyers, our trampolines comply fully with EN 71-14:2018 (Safety of toys - Trampolines for domestic use). They carry TÜV-GS (Geprüfte Sicherheit) certification, ensuring chemical safety under REACH (EC 1907/2006) for phthalates and polycyclic aromatic hydrocarbons (PAHs) in spring padding and plastic components.
Australian conditions present severe solar UV intensity. Our products engineered for Oceania utilize enhanced UV-inhibitor masterbatches mixed into the PP mat and PE enclosure nets, passing rigorous weathering protocols specified by AS 4989:2015 safety standards.
Deep-dive specs and engineering values of our flagship trampoline series recognized by international procurement agents.
Funjump's flagship round outdoor trampoline line covers all standard diameters from 6 feet up to 16 feet. Designed with a priority on multi-child backyard recreation, this system uses high-yield strength steel legs paired with W-shaped ground stabilizers.
Key Engineering Features:
Specifically engineered to solve impact hazards associated with straight enclosure poles, this model features out-curved frame poles. By arching the support steel away from the net wall, the safety clearance zone is increased by over 30%, virtually eliminating child impact with rigid metal supports during high-energy jumping.
Key Engineering Features:
Targeted at toddlers aged 3 to 6 years, this 55-inch mini trampoline eliminates traditional metal springs entirely, replacing them with ultra-quiet, high-elasticity synthetic bungee ropes. This prevents pinches and delivers a smooth, low-impact bounce ideal for early motor skill development.
Key Engineering Features:
Created for adult aerobic workouts, studio bounce classes, and commercial gym settings, this 51-inch rebounder incorporates a heavy-duty T-shaped stability bar with multi-level height adjustment settings.
Key Engineering Features:
Clear, direct answers to common wholesale, manufacturing, logistics, and technical specification queries.
Complete product catalog options including rectangular units, fitness rebounders, and toddler play stations.
