Explore our industrial-grade storage solutions, custom-engineered for extreme durability, flexible configurations, and high load capacity.
An in-depth analysis of structural calculation, international safety compliance, supply chain engineering, and localized optimization strategies.
In modern industrial operations, logistics managers and plant engineers face the continuous challenge of maximizing spatial density while maintaining optimal pick efficiency. Longspan storage systems represent the critical bridge between lightweight boltless shelving and heavy-duty selective pallet racking. Globally, the demand for medium-duty, high-capacity longspan shelving has grown exponentially due to the rapid development of third-party logistics (3PL), e-commerce fulfillment hubs, and automated micro-fulfillment facilities.
Unlike standard racking designed solely for unit loads on pallets, longspan systems accommodate manual loading of diverse SKUs, oversized boxes, and heavy bulk components. By integrating heavy-duty Z-beams or step-beams with steel decks, wire mesh decking, or chipboard, longspan systems provide dynamic storage architectures that adapt to shifting inventory profiles. In areas such as North America, Europe, and Australia, strict warehousing regulations demand that these systems not only hold weight, but also resist seismic forces and accidental impact.
"The optimization of warehouse volume is no longer just about floor area; it is about dynamic load distribution and modular flexibility. Longspan racking allows operators to scale vertically without relying exclusively on expensive forklift-driven setups."
Shenzhen Kimsuk Storage Equipment Manufacturing Co., Ltd. designs and manufactures storage systems based on cold-rolled steel science. Our systems are engineered using high-tensile Q235B and Q355B structural steel, ensuring uniform load distribution and minimum structural deflection under maximum capacity.
| Component | Standard Specifications | Heavy Duty Range | Surface Treatment |
|---|---|---|---|
| Upright Frame Profile | 55×47 / 60×50 mm (1.5mm - 1.8mm) | 80×60 / 90×70 mm (1.8mm - 2.5mm) | Electrostatic Epoxy Powder Coated (60-80μm) |
| Step Beam Section | P50×30 / P60×40 mm (Step: 28mm) | P80×50 / P110×50 mm (Step: 28mm) | Anti-Corrosion Pre-galvanized / Coated |
| Shelving Deck Type | Steel Panel (0.6mm - 1.0mm thickness) | Wire Mesh Decking / Timber Board | Zinc Plated / Powder Coated Glossy |
| Load Capacity (UDL) | 300kg - 800kg per level | 1000kg - 5000kg per level | Tested to 1.5x Safety Deflection Limit |
Every roll-formed upright frame utilizes a teardrop or diamond punching pattern with a 50mm vertical pitch, allowing toolless, incremental beam adjustments. The beam-to-frame connection features a multi-tang heavy-duty connector bracket secured with automatic safety drop-locks to prevent accidental beam dislodgement from forklift forks or manual handling.
Industrial environments demand highly customized storage configurations. We tailor our systems to fit regional warehouse constraints and vertical requirements:
Integrated as multi-tier pick towers featuring wire mesh decking and carton-flow accessories to accelerate order preparation and optimize inventory access.
Engineered for storing long, heavy, and awkward components (exhaust pipes, body panels, and engine blocks) using heavy steel panel inserts.
Utilizes custom corrosion-protected structural components that withstand continuous exposure to sub-zero temperatures (-30°C) without losing load-bearing capacity.
Sourcing industrial equipment directly from China-based manufacturers like Shenzhen Kimsuk provides distinct advantages in raw material access, industrial clustering, and scale of production. Located in the Pearl River Delta, our factory enjoys proximity to top-tier steel mills and direct deepwater ports (Shenzhen and Guangzhou).
We manage production costs through vertical integration and relationships with over 850 verified supply chain partners. This structure allows us to secure raw materials at stable pricing even during global market shifts. With a modern 18,500㎡ factory footprint and automated production machinery, we deliver quality precision components at scale, offering clear cost efficiencies to global distributors.
At Kimsuk, quality control is a structured engineering process. Our testing protocols cover every phase from raw material verification to final surface thickness checks. Under the supervision of 45 specialized inspectors, our equipment undergoes continuous physical testing.
Our production lines comply with global standards: FEM 10.2.02 (European Racking Code), RMI (Rack Manufacturers Institute for North America), and AS4084-2012 (Steel Storage Racking standard for Australia). Using laser measurement devices, coating thickness gauges, and hydraulic load testers, we verify weld penetration, paint adhesion, and load capacity to ensure every shipment complies with industrial safety regulations.

To match the changing needs of logistics global markets, Kimsuk's R&D department (comprising 18 design engineers) is developing new product integrations. Key focus areas include:
Common questions from B2B buyers and structural engineers regarding product design, manufacturing standards, and installation.
Our standard longspan storage shelves accommodate load capacities ranging from 300kg to 1000kg per shelf level. For heavier requirements, we supply custom industrial shelving platforms capable of supporting up to 5000kg per level. These higher configurations utilize specialized structural step beams, thickened steel panels, and additional under-shelf reinforcement ribs.
Kimsuk storage systems are engineered to meet global standards. We design, manufacture, and verify our racking according to European FEM 10.2.02 specifications, American RMI guidelines, and Australian AS4084-2012 steel racking regulations. Full material testing data sheets, coating thickness reports, and structural calculations are available upon request.
With 18 professional design engineers on staff, we provide full custom layout engineering. Options include frame depth modifications, custom load profiles, custom paint color matching (RAL system), specialized steel gauges (up to 2.5mm thickness), and options for dynamic warehouse configurations, including integrated mezzanine flooring.
We implement quality checks at multiple stages: inspecting raw steel grades, testing weld integrity, measuring paint thickness, checking dimensions, and performing load tests. Our QC team of 45 inspectors monitors the entire fabrication process. Before shipping, we inspect weld penetration, powder coat thickness, and finish quality.
Yes, our light-to-medium duty systems utilize a boltless connection system. Uprights and step beams lock together using steel connectors. Frame assemblies can be quickly completed using standard rubber mallets. For heavy industrial installations, we supply structural locking bolts and floor-anchoring baseplates to ensure lateral stability.
Our standard production lead time is 15 to 25 days from deposit confirmation, depending on order volume. We provide packaging options (bubble wrap, cardboard protectors, and steel strapping) to prevent damage during transit. Our export team coordinates logistics with global shipping lines from Shenzhen and Guangzhou ports.
