Explore our high-density dynamic storage frameworks and logistics robotics designed for seamless warehouse transformation.
Vietnam is experiencing an unprecedented industrial surge. Supported by bilateral free trade agreements and foreign direct investment (FDI) inflow, major industrial corridors from Bac Ninh and Hai Phong in the north, to Binh Duong and Dong Nai in the south, have emerged as global manufacturing powerhouses. With warehouse lease rates rising rapidly, companies are transitioning from traditional layouts to space-efficient vertical storage architectures.
Gravity Sliding Racks (also known as Gravity Pallet Flow Racks) play a key role in this industrial shift. Driven by gravity, these systems operate on a First-In, First-Out (FIFO) retrieval workflow, eliminating the need for internal access aisles and reducing warehouse footprints by up to 60%. As Vietnam strengthens its logistics networks to support e-commerce, cold-chain operations, and electronics manufacturing, advanced gravity flow systems have become essential to modernizing the regional supply chain.
Strategic Growth Insight: Modern factories in Vietnam are standardizing dynamic gravity systems to maximize storage densities, reduce forklift operation times, and establish smooth buffer lines that interface directly with shipping docks.
Designing high-capacity gravity flow racking demands rigorous mechanical analysis. It is not simply a matter of steel assembly; it is an engineered interaction between velocity, friction, gravity, and load-bearing configurations.
Operating a heavy-duty pallet flow system requires precise slope calculation and velocity regulation to ensure safe warehouse conditions. If the inline gradient is too steep, heavy pallets may accelerate dangerously; if it is too flat, pallets risk stalling mid-lane, disrupting FIFO flow.

Operating a sprawling 38,000 square meter smart facility, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. manages every stage of production under strict quality controls. Our automated welding machinery and precision rolling lines provide structural resilience, helping us deliver stable warehouse solutions to global partners.
Sunli's quality control workflow is managed by a team of 35 QC professionals who oversee compliance audits on every raw material batch and finished weldment. Using specialized equipment, we verify key performance attributes to deliver reliable racking structures.
Sunli works closely with logistics operators, engineering heads, and industrial designers in Vietnam to tailor racking configurations to specific market requirements.
In regions like the Mekong Delta and around major ports like Da Nang and Ho Chi Minh City, agricultural cold chain systems require energy-efficient space solutions. Every cubic meter of sub-zero storage comes with high power costs. Our heavy-duty gravity flow racks maintain reliable rolling performance down to -30°C, and they increase cold room storage capacity by up to 60% compared to traditional selective racking.
With Vietnam's domestic e-commerce sector growing rapidly, urban logistics terminals near Hanoi and HCMC require fast order sorting and fulfillment. Carton gravity flow shelves provide organized, high-density storage for split-case picking, helping pickers select products quickly and reduce transit times within the facility.
As international electronics and automotive manufacturers set up plants in Vietnam's northern industrial zones, managing assemblies on a strict FIFO basis is critical. Our heavy-duty gravity flow racks help maintain component rotation and supply line buffers, preventing stagnation of temperature-sensitive or high-value parts.
Compliance Note for Industrial Zones: All Sunli gravity systems are structural load-tested to meet EN 15512 and RMI specifications, giving operators the compliance documentation required to clear rigorous building inspections in Vietnam's industrial parks.
Modern warehouse distribution is transitioning toward automated storage and retrieval system (ASRS) environments. Gravity sliding racks function effectively as physical buffer zones between manufacturing halls and final dispatch bays.
By pairing gravity lanes with Automated Guided Vehicles (AGVs), factories can automate repetitive transport routes. The gravity lanes serve as dynamic storage buffers, gravity-feeding pallets directly to picker stations or robotic load adjusters without requiring manual intervention.
Sunli manufactures a wide range of logistics equipment, from structural mezzanines and heavy-duty static racks to laser-guided AGVs.
Answers to common questions about designing, installing, and importing dynamic warehouse racking systems in Vietnam.
The standard incline gradient for gravity pallet flow racking ranges between 3.5% and 4.0%. For lightweight carton flow shelves, the slope can be configured up to 5%. Custom slope adjustments are determined based on trial tests matching the weight profiles and base characteristics of your pallets (e.g., plastic, wood, or steel skids).
We integrate magnetic speed controllers (braking rollers) at calculated intervals within the roller track. These non-powered controllers apply self-regulating magnetic resistance, maintaining pallet speed below 0.3 meters per second to prevent collision damage within the storage lane.
Yes. Our racking structures are calculated using Finite Element Analysis (FEA) to ensure compliance with EN 15512 and RMI design standards. For installations in Vietnam, we adjust structural baseplates and anchoring configurations to meet regional seismic safety requirements.
We clean our roll-formed steel with an acid wash before applying an electrostatic powder coating with a dry film thickness exceeding 80μm. This coating protects the structural framing from moisture exposure in humid tropical environments.
Yes, gravity flow racking functions effectively as a structural buffer zone. The input and output lanes are designed with precise structural limits, allowing automated cranes (ASRS) and AGV forklifts to place and retrieve pallets accurately.
Manufacturing typically takes 20 to 30 days depending on the structural configuration. Shipping from our facility to major ports in Vietnam (such as Hai Phong or Cat Lai) takes between 3 and 7 days, allowing for efficient project delivery.
