Optimize your vertical cubic volume with our heavy-duty, very narrow aisle (VNA) systems, structural racking platforms, and space-saving metal shelves designed to maximize floor space and processing efficiency.
Dongguan Jinhui Storage Equipment Co., Ltd. leads the engineering of advanced structural and industrial warehouse racking.
Established in 2017, Dongguan Jinhui Storage Equipment Co., Ltd. has developed into a premium high-density storage hardware manufacturer. Our dynamic engineering and processing infrastructure is custom-tailored to provide safety, capacity optimization, and structural reliability for massive logistics hubs, retail distribution centers, and manufacturing plants worldwide.
Over the years, we have built a stable procurement footprint, supported by a network of over 980 supply chain partners. This ecosystem guarantees stable, direct sourcing of high-tensile structural steel (Q235B and Q355B), ensuring cost-efficiency and reliable lead times for long-term commercial contracts.
Our production facilities are equipped with automated cold-roll forming mills, multi-station continuous CNC punching presses, heavy-duty laser profiling lines, and robotic welding stations. We execute complete vertical control over our supply chain from sheet-slitting to powder coating.
We work closely with global industrial architects and structural engineers. Last year alone, Jinhui's dedicated engineering teams launched and customized over 126 new storage system designs and structural upright upgrades, meeting diverse layout requirements in Europe, North America, Southeast Asia, Australia, and the Middle East.
High-density VNA systems offer significant space savings but require precise engineering, tight structural tolerances, and specific installation methods.
By narrowing aisles to 1.5M - 1.8M (a 50%+ reduction compared to selective racking) and engineering upright assemblies up to 18 meters, VNA storage systems maximize warehouse capacity without expanding floor area.
To prevent collisions, high-speed turret trucks navigate using mechanical steel guide rails or electromagnetic wire-guidance paths. Jinhui supplies custom guide rail configurations for smooth, automated path-following.
High vertical frames require strict deflection tolerances. Our structural members are engineered using cold-formed, high-grade steel, ensuring minimal sway and high load stability under dynamic forces.

Step-by-step documentation of our structural racking manufacturing process. Every stage is optimized for material integrity and dimensional precision.
Our QC team of 46 inspectors ensures compliance with ISO 9001 and CE requirements, conducting structural load and dimensional tests before delivery.
Jinhui's specialized VNA and pallet racking systems address specific challenges in challenging logistics and manufacturing environments.
Maximizes cubic density in temperature-controlled spaces, reducing cooling costs per pallet. High-grade galvanization prevents corrosion from humidity and cleaning chemicals.
Supports high turnover with 100% SKU selectivity. Integrates with warehouse management systems (WMS) and RFID tracking for high pick accuracy.
Accommodates heavy, concentrated components. Heavy-duty beams, safety railguards, and deck supports are designed for high point loads.
We continuously update our manufacturing processes to meet changing warehouse requirements and support logistics automation.
Modern high-bay VNA warehouses require specialized seismic engineering. Using Finite Element Analysis (FEA), our design engineers simulate seismic forces to customize baseplates, frame bracing, and beam connectors, ensuring stability under dynamic loads and earthquake conditions.
Our structures comply with international standards including Europe's FEM 10.2.02, the US RMI code, and Australia's AS4084, allowing for seamless integration into global supply chains.
The rise of Automated Storage and Retrieval Systems (ASRS) and AGV turret trucks requires highly precise racking tolerances. Jinhui is developing micro-tolerance manufacturing processes to ensure alignment with laser and sensor-guided automation, reducing equipment wear.
Additionally, we integrate IoT sensor arrays within structural members, allowing real-time monitoring of strain, load changes, and structure verticality in smart warehouses.
