Explore our featured structural warehouse mezzanine systems, cantilever racks, heavy-duty display equipment, and high-performance storage shelving designs.
Modern supply chains demand highly flexible space optimization. Medium-duty storage systems occupy a critical operational segment between light-duty retail shelving and heavy-duty structural pallet racking. Generally handling weight loads ranging from 200kg to 800kg per level, medium-duty shelving is the foundational component of global logistics hubs, localized e-commerce fulfillment centers, automotive parts warehouses, and industrial manufacturing assembly lines.
As micro-fulfillment and rapid regional distribution continue to expand, the demand for customizable, boltless longspan structures has reached an all-time high. Global procurement managers require systems that can be rapidly configured, expanded vertically, and constructed without specialized tools, all while complying with strict occupational safety and load-bearing standards (such as EN 15635 and FEM regulations).
Global Tier-1 Storage Infrastructure Manufacturing Partner
Established in 2014, Ningbo Kelida Shelf Co., Ltd. has positioned itself as an industry leader in manufacturing industrial warehouse racking and heavy-duty storage shelving. Utilizing cold-rolled steel and highly optimized automated production lines, Kelida integrates advanced structural engineering with commercial-grade scalability. With 8 years of dedicated international trade experience, we ship structural solutions directly to major distribution centers in North America, Western Europe, Southeast Asia, and the Middle East.
Our operation is built on supply chain agility. We coordinate with a network of over 650 qualified raw material and component suppliers, ensuring steady access to premium steel and high-durability accessories even during periods of global supply volatility. This robust integration allows us to offer shorter lead times and highly competitive OEM/ODM pricing for complex, custom racking systems.
How Kelida delivers premium structural performance with cost-efficient scalability.
Our facility operates state-of-the-art automated roll forming, robotic welding, and high-speed CNC punching stations. Automation ensures mechanical consistency across every beam, upright, and brace, keeping structural tolerances within 0.1mm.
Equipped with a continuous overhead automated powder coating line, we apply thermosetting epoxy polyester powder at a thickness of 60 to 80 microns. This yields excellent resistance against impact, surface scratching, and chemical exposure.
Backed by 22 QC specialists, every batch of steel undergo mechanical tensile tests, weld ultrasound inspections, dynamic load stress tests, and salt-spray corrosion chamber testing to guarantee safety under maximum load.
From micro-fulfillment hubs to harsh outdoor environments, Kelida storage solutions adapt to your exact sector requirements.
In high-throughput e-commerce fulfillment hubs, efficiency is measured by picking speed and vertical space utilization. Our customized mezzanine systems and longspan shelving units are integrated directly to support complex conveyor networks, automated guided vehicle (AGV) pathways, and multi-tier picking platforms. By engineering custom shelf heights and incorporating high-strength steel deck options, we help companies triple their SKU density without expanding their physical warehouse footprint.
Automotive warehouses must manage thousands of high-density, varying-weight parts, from small fasteners to heavy engine components. Our medium-duty shelving units, built with adjustable steel decking and customized pegboard dividers, provide the structured stability required for high-velocity parts pick operations. The durability of our industrial coatings prevents metal wear even when exposed to lubricants, hydraulic fluids, and heavy metallic contact.
For supermarket chains, furniture outlets, and home improvement stores, backrooms must function as rapid replenishing centers. Our cold-rolled steel wood-structure gondola shelving and customizable supermarket fruit/vegetable displays bridge the gap between backroom stock retention and front-of-house commercial appeal. Steel-wood integration offers clean, retail-ready aesthetics with the structural payload capacity of high-strength warehouse racks.
Standard indoor powder coatings will fail under direct UV exposure and precipitation. For outdoor pipe, timber, and building material storage, Kelida supplies heavy-duty galvanized cantilever racking systems. The hot-dip galvanization process provides thick zinc-iron alloy protection that seals structural steel channels against rust, moisture intrusion, and temperature fluctuations, ensuring decades of safe outdoor operation.

How next-generation warehousing models are redefining industrial shelf design.
The global storage sector is transitioning rapidly toward integration with high-speed automated systems. Dynamic storage configurations are replacing static racks to reduce floor footprints and support automated pick paths. Here are the core structural changes our R&D department is designing for next-generation facilities:
Key performance benchmarks to review when sourcing medium-duty storage products.
Purchasing structural racking systems involves navigating local safety regulations, shipping weight restrictions, and long-term durability. To ensure smooth delivery and compliance, keep these considerations in mind:
Always verify the raw material grade. For premium medium and heavy-duty structural applications, specify Q235B or Q355B cold-rolled steel. These grades provide the necessary yield strength and elongation characteristics to prevent dynamic deformation.
Verify that your supplier calculates weight limits based on Uniformly Distributed Load (UDL) principles. Avoid selecting shelves based solely on static capacity if they will experience dynamic impact from forklifts or automated loaders.
Ensure the powder coating application process includes chemical cleaning and phosphate pre-treatments. This guarantees the paint layer adheres securely, preventing moisture from reaching the underlying steel.
Shipping costs represent a significant portion of international procurement. Choose a manufacturer that packages components using customized wooden pallets, bubble wrap, and structural steel strapping to protect finishes and maximize sea container volume.
