Explore our premium range of CE certified heavy-duty structures, automated handling equipment, and customizable rack configurations designed to optimize space utilization.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has grown into a world-class manufacturing authority specializing in structural storage engineering, intelligent racking systems, and dynamic FIFO (First-In, First-Out) gravity flow systems. Operating from our advanced 38,000 m² automated manufacturing hub, we merge structural steel manufacturing with high-precision logistics automation to solve complex footprint bottlenecks across the globe.
With an annual export value exceeding $18 million to $25 million, our logistics installations empower distribution centers in North America, Western Europe, Southeast Asia, and the Middle East. Through strict adherence to ISO 9001 and CE directives, we design, test, and manufacture products that provide continuous material rotation, improved pick paths, and ultimate safety compliance.
Every dynamic racking design undergoes finite element analysis (FEA) to verify shear structural strength.
Ensuring complete safety compliance in line with European FEM standards and EN regulations.
In modern industrial logistics, static storage is rapidly evolving into dynamic, space-optimized material flow layouts. Understanding the mechanics of FIFO is critical to operational scale.
With skyrocketing real estate values worldwide, logistics providers can no longer afford wide, empty aisles. FIFO (First-In, First-Out) gravity flow racking provides a compact solution by transforming longitudinal depth into active storage channels. In North America and Western Europe, cold chain operations, food processing hubs, and pharmaceutical distribution networks depend heavily on FIFO configurations. These systems guarantee batch control and fresh inventory rotation while reducing forklift travel distances by up to 40%.
The industry is transitioning toward hybrid setups. Static gravity lanes are increasingly integrated with Automated Guided Vehicles (AGVs) and Laser Guided Forklifts (LGFs). By installing automated release mechanisms and magnetic braking rollers, manufacturers can run heavy-duty dynamic systems without manual intervention. Our technical roadmap incorporates high-strength cold-rolled Q235B steel alongside precision-machined roller tracks, ensuring continuous, worry-free operation even in deep-freeze environments down to -30°C.
Dynamic loads place continuous cyclic stresses on storage structures. An out-of-tolerance rack can lead to structural failure or progressive collapse. Our CE marking certifies compliance with safety standards (EN 15512, EN 15620, and FEM 10.2.02 codes). We conduct physical impact tests, cross-cut adhesion tests on coatings, and micro-metric thickness checks to guarantee that every frame can withstand years of heavy, dynamic loading.
A true FIFO racking system consists of multi-level inclined roller lanes configured with specific slope angles (typically 3% to 4%). As a forklift deposits a pallet at the loading end, gravity moves it smoothly down to the unloading end. Safe operation requires highly specific engineered components:
Our structures are optimized through precise material selection and automated manufacturing to withstand continuous high-capacity operations.
We source certified structural steel (Q235B and Q355 profiles) to ensure optimum elasticity and high yield points. All components undergo precise fabrication stages:
Our quality assurance department utilizes calibration and testing equipment to monitor every production batch:
Our production facilities utilize modern machinery and strict testing protocols to deliver durable racking systems.
From high-volume logistics centers to strict pharmaceutical facilities, our dynamic storage racks optimize spatial productivity.
Cold storage facilities face high electricity and refrigeration costs. Minimizing unused space is critical to reducing operating expenses. Our dynamic gravity systems are engineered specifically for sub-zero temperatures (down to -30°C). By eliminating wasted aisle space and using specialized low-temperature lubricants on rollers, our designs improve air circulation and save up to 50% in cooling costs.
In modern e-commerce operations, order pick velocity determines profitability. Our carton flow racks organize high-density pick zones by presenting cases directly to picker aisles. Incorporating entry guide angles and speed separation brackets, these configurations improve picking speeds and reduce errors, enabling seamless inventory rotation.
In food and pharmaceutical storage, maintaining batch trace stability is a critical regulatory requirement. By organizing products in a first-in, first-out sequence, these industries can keep expiration dates in order and prevent inventory loss from write-offs. Our non-toxic, anti-static electrostatic finishes prevent product contamination and stand up to rigorous sanitization schedules.
Read through expert answers about dynamic gravity flow systems, load calculations, and safety standards.
Most gravity pallet flow racks utilize a standard incline slope between 3% and 4% (approximately 1.75 to 2.3 degrees). The exact angle depends on the pallet weight range, load characteristics, and roller material. Our R&D engineers calculate this using load simulations to ensure consistent pallet movement without excessive acceleration.
All our rack designs undergo extensive structural testing, including FEA simulation modeling. We strictly follow European FEM 10.2.02 and EN 15512 standards. Additionally, our 35 QC professionals conduct physical stress tests, weld inspections, and coating checks to verify safety compliance.
Yes, our automated racking systems are built to integrate with AGVs and AS/RS machinery. We include exit separators and positioning components that align with automated warehouse workflows.
We provide full OEM/ODM services. We can customize dimensions, frame columns, and load capacities (from 200kg up to over 2000kg per pallet position). You can also customize powder coating colors to match your brand requirements.
To prevent pallet jams in long runs, we integrate dynamic speed controllers and mechanical brakes. These slow the pallets to a safe speed as they roll. Exit separators relieve forward line pressure on the picking face, ensuring smooth unloading.
