Engineered to comply with AISC, RMI, and EN safety standards, optimizing vertical warehouse cube capacity.
Established in 2015, Shenzhen Lijin Storage Equipment Co., Ltd. is a global market leader in the design, engineering, and high-volume manufacture of industrial platform racks, multi-tier steel mezzanines, and structural logistics equipment. Our modern manufacturing base spans a state-of-the-art facility of 35,000 m². Over the past decade, we have scaled our capacity to serve high-level global enterprises, integrating 8+ years of dedicated export compliance with 12+ years of direct industry structural engineering knowledge. Last year, our global revenue crossed USD 22 million, reinforcing our market presence in high-density storage development.
We operate as a complete end-to-end solutions partner. From standard structural pallet racks to heavy-duty, multi-level steel mezzanine systems supporting up to 2,000 kg/m², we resolve complex spatial bottlenecks for modern industrial businesses. Our engineering teams leverage advanced Finite Element Analysis (FEA) to ensure all structures safely withstand regional load characteristics, including dynamic forklift forces and seismic configurations.
We enforce a comprehensive, multi-stage quality assurance architecture, including non-destructive ultrasonic testing, automated robotic weld line inspection, laser dimensional validation, and physical heavy-load endurance testing. Our dedicated team of 35 QC inspectors guarantees that every production run complies with CE, AS4084, and ISO 9001:2015 directives.
With structural steel exports spanning North America, Western Europe, Southeast Asia, and the Middle East, we support over 850 strategic supply chain partnerships. Our structural platforms and racking components are optimized for efficient container packing, lowering international freight costs and streamlining onsite assembly.
Our division is led by 28 R&D structural engineers specializing in custom-designed storage systems. Last year, the group developed over 85 customized configurations, meeting specific requests for earthquake-resilient rack engineering, automated storage and retrieval system (ASRS) interfaces, and corrosive environment coatings.
A comprehensive review of modern material handling engineering, structural steel selections, and design criteria for international supply chains.
In modern supply chain management, land acquisition and warehouse construction costs continue to rise. Industrial operators face pressure to optimize cubic volume utilization rather than expanding their horizontal footprint. Heavy-duty platform racks and mezzanine floor structures offer a viable solution by converting unused vertical clearance into safe, structural, and load-bearing floor space. By utilizing high-capacity industrial platforms, companies can double or triple their operational floor area, deferring the capital expenditures associated with facility relocation or expansion.
Industrial platform racks act as structural frameworks that support walkways, production zones, assembly lines, or secondary racking layouts. Unlike standard light-duty modular shelving, structural platform systems must support combined static and dynamic loads, including automated guided vehicles (AGVs), pallet jacks, heavy machinery, and dense pedestrian traffic. Specifying these systems requires structural analysis of columns, primary support girders, joists, and flooring surfaces.
The integrity of a platform racking system depends on its base metallurgy. In Chinese manufacturing, structural steel grades Q235B and Q355B (conforming to GB/T 1591 and GB/T 700) serve as the primary materials. Understanding their mechanical differences is essential for international procurement:
By selecting the correct steel grade and thickness (often ranging from 2.0mm to 6.0mm for cold-rolled configurations), Lijin engineers optimize the weight-to-strength ratio. This approach reduces overall dead load on the concrete slab while meeting required safety margins.
| Steel Grade (Standard) | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Primary Industrial Application |
|---|---|---|---|---|
| Q235B (GB/T 700) | 235 Min | 375 - 500 | ≥ 26 | Standard racking beams, bracing, wire decking, light mezzanines |
| Q355B (GB/T 1591) | 355 Min | 470 - 630 | ≥ 22 | Heavy-duty structural H-beams, main platform columns, high-span girders |
| SS400 (JIS G3101) | 245 Min | 400 - 510 | ≥ 21 | Export-grade general structural framing and connection plates |
| S355JR (EN 10025) | 355 Min | 470 - 630 | ≥ 22 | European-standard heavy structural mezzanine floor layouts |
The global sourcing of platform racks is concentrated in China's industrial manufacturing hubs. Shenzhen Lijin combines cost advantages, supply chain integration, and automated production technologies:
Supply Chain Integration: Located near large steel production facilities and major global shipping ports (Shenzhen and Guangzhou), we reduce raw material transport costs and export logistics handling.
Advanced Automation: Our facility utilizes continuous automated roll-forming lines, multi-axis CNC laser cutting machines, and robotic welding stations. These automated lines ensure uniform profiles with minimal thermal distortion, which is critical for consistent bolt-hole alignment across 12-meter structural uprights.
Electrostatic Powder Coating: Our automated cleaning and powder-coating line applies a durable thermo-hardened epoxy-polyester finish. This coating provides impact, scratch, and chemical resistance, protecting structural steel in cold-storage and high-humidity environments.
From raw steel coils to precision-machined structural platform components: our 18-step production line.
How structural platforms adapt to localized industries, code compliance, and specific environmental factors.
Industrial platform racks are custom-designed for different industry sectors:
Under FEM 10.2.02 and RMI standards, structural designers calculate beam deflection limits based on the span length (L). For pedestrian steel platforms, the deflection limit is typically L/300. For platforms supporting precision conveyor equipment or AGVs, this limit is restricted to L/500 or L/1000 to prevent structural sagging and operational interference.
The typical load-bearing categories for platform racks include:
For projects in seismic regions (such as sections of the US West Coast, Italy, New Zealand, or Japan), platform racks must include seismic designs. Designers use regional peak ground acceleration (PGA) metrics to calculate seismic forces. Columns require oversized base plates with concrete anchor bolts to distribute lateral seismic forces across the warehouse slab.
A structured roadmap from initial site survey to structural calculations and container loading.
We collect detailed building drawings (CAD/PDF), noting ceiling clearance, column locations, concrete floor thickness, and door openings. Our engineers then produce 2D layout options and 3D spatial models to optimize cubic volume.
Using computer modeling, we simulate structural stress under maximum load, wind, and seismic events. This step verifies deflection limits and connection details before fabrication begins.
Selected steel coils undergo automated slitting, high-speed roll forming, punching, and welding. Robotic weld stations ensure uniform penetration on connections.
Parts pass through chemical cleaning to remove surface scale, followed by electrostatic powder coating and baking. QC teams inspect coat thickness, adhesion, and weld quality.
Platform components are wrapped in air-bubble packaging, bundled with steel strapping, and loaded into ocean containers. This secure packaging prevents movement and paint scratching during transit.
We provide detailed 3D installation drawings, assembly manuals, and video walk-throughs. For complex projects, our engineers provide remote or on-site supervision to ensure correct torque and alignment.
