Understanding the engineering principles, structural specifications, and supply chain strategies that drive modern global logistics warehousing.
In modern industrial storage, the gap between light-duty shelving and heavy pallet racking is filled by Longspan Shelving. This system is specifically designed for warehouses where goods are handled manually rather than loaded on pallets. It accommodates high-volume, medium-weight items, providing easy accessibility and modular flexibility.
Unlike standard shelving, longspan structures employ high-tensile steel upright frames and horizontal beams to bridge longer spans without risking structural sagging or structural failure. This makes it perfect for e-commerce hubs, automotive parts distribution, and retail backrooms.
Procurement directors and warehouse managers prioritize safety certifications, structural longevity, and payload optimization. A typical evaluation includes analyzing standard load calculations per level, selecting the appropriate deck material (wire mesh, galvanized steel, or particle board), and assessing the manufacturer's compliance with global structural codes.
Partnering directly with a specialized manufacturer like Nanjing Ciho Racks ensures access to customized OEM/ODM sizing, custom-designed load profiles, and precision-rolled components that reduce operational risk and shipping costs.
Our longspan structures are built using premium cold-rolled steel and are tested under strict loads to ensure safety factors of at least 1.5 to 1.8. Below are the core technical specifications standard across our product ranges:

Quality and durability are built at the factory level. We maintain strict control over every stage of our production process. Below is a detailed look at our advanced manufacturing workflow and modern machinery:
How Nanjing Ciho Racks leverages structural steel resources, industrial clusters, and international certification structures.
China produces over half of the world's crude steel. Located in Nanjing, one of the premier racking manufacturing hubs in China, Ciho Racks has direct access to high-grade Q235B and Q355B structural steel. This raw material security allows us to control costs and source certified steel directly from state-owned mills like Baosteel and Ansteel.
Additionally, the local supply chain ecosystem provides highly specialized, automated tooling, advanced zinc-coating facilities, and world-class shipping links via the Port of Shanghai and Port of Nanjing. This enables us to offer shorter production lead times and competitive pricing without compromising quality.
Global logistics facilities require structural compliance to secure insurance coverage and guarantee worker safety. Our manufacturing processes conform to international standards, including:
We provide localized engineering support by offering full 3D CAD design files, structural stress analysis reports, and load-limit documentation required by municipal inspectors. For massive distribution projects, we collaborate with local installers and project managers in North America, Europe, and Australia to ensure that our racking fits seamlessly into local logistics ecosystems.
To resist corrosion in humid and cold-storage environments, we utilize a multi-stage pre-treatment wash followed by electrostatic epoxy-polyester thermosetting powder coating. This results in a hard, durable finish that resists scratching, moisture, and chemical exposure. Pre-galvanized components are also available for cold storage and agricultural applications.
Deploying modular longspan shelving in diverse commercial operations while keeping up with changing warehousing technologies.
Modern fulfillment operations require rapid SKU sorting and picking. Our step-beam and wire-mesh deck designs allow for easy labeling and division, accommodating diverse carton storage configurations. This setup integrates smoothly with conveyor lines and pick-to-light systems.
Automotive components vary in weight and shape. The adjustable nature of our medium and heavy-duty longspan profiles allows users to customize shelf spacing easily, ensuring safe storage for heavy brakes, exhausts, and body panels without bowing or flexing.
For temperatures down to -30°C, cold storage facilities require steel that maintains structural properties and finishes that prevent corrosion. Our hot-dip galvanized panels and frames are highly resistant to moisture, making them ideal for walk-in cold rooms and pharmaceutical storage.
The warehouse management landscape is evolving. When planning modern facility layouts, several key trends impact the design and integration of longspan shelving:
Detailed answers to help you navigate structural engineering, load calculations, custom ordering, and logistics.
Pallet racking is designed to hold heavy, palletized loads and is serviced by forklifts. Longspan shelving, on the other hand, is built for manually loaded boxes, cartons, and loose components. It uses step beams and decking panels (steel, wood, or wire mesh) to support weights ranging from 200 kg to 800 kg per level, making it highly versatile for picking lines.
We calculate capacity using finite element analysis (FEA) based on the structural profile, material thickness, and beam length. The load rating is calculated as Uniformly Distributed Load (UDL). This means weight must be spread evenly across the entire shelf surface. Deflection is kept within structural safety limits, typically 1/200th of the span, in accordance with FEM guidelines.
Yes. Nanjing Ciho Racks provides complete OEM and ODM customization. We can adjust upright post heights, frame widths, beam lengths, profile thicknesses, and powder-coating colors to meet your warehouse layout and operational goals.
To protect components during shipping, we pack upright frames and beams using heavy-duty strapping, air bubbles, protective plastic film, and solid wooden pallet bases. We also place airbags inside the shipping container to prevent shifts and friction during transport.
Typically, a standard 20ft or 40ft container order takes 15 to 25 days to manufacture. Lead times can vary depending on customization requirements, raw steel sourcing schedules, and current production capacity. We will provide a firm production and delivery schedule before order confirmation.
