Designed to bridge the gap between light industrial shelving and heavy selective pallet racks, supporting load ranges from 200kg to 800kg per tier with fully adjustable structural modularity.
In modern intra-logistics architectures, Medium Duty Racking—typically cataloged under Type A and Type B industrial longspan profiles—represents the core physical infrastructure for manual carton picking, intermediate buffer storage, and sub-assembly fulfillment lines. Sourced primarily from certified Chinese manufacturers, these structural systems resolve the critical operational gap where light boltless angle shelving lacks dynamic rigidity, yet heavy structural pallet racks yield prohibitive capital expenditure per cubic meter of hand-loaded inventory.
Precision manufacturing begins with certified high-yield Q235B cold-rolled structural steel coils. Upright columns undergo continuous multi-stage roll-forming with precision butterfly or teardrop pitch punchings configured at exact 50mm or 75mm increments. Unlike lightweight commercial wire shelving that relies on spot welding, top-tier Chinese medium duty racking employs step-beam or P-beam horizontal profiles. The integrated step accommodates flush-fitted cold-rolled steel decking panels, high-density melamine boards, or galvanized wire mesh decking, dispersing uniformly distributed loads (UDL) up to 800 kg per shelf tier safely.
Selecting an optimal racking topology requires balancing beam deflection allowances (standard L/250 under FEM 10.2.02 codes), seismic vulnerability ratings, and accessibility requirements. The following matrix illustrates the structural differences between dominant configurations exported from China:
| Designation Parameter | Medium Duty Type A (Step Beam) | Medium Duty Type B (P-Beam / Box) | Multi-Tier Shelving Supported |
|---|---|---|---|
| Load Rating per Level (UDL) | 200 kg – 450 kg / layer | 400 kg – 800 kg / layer | 250 kg – 500 kg / layer + 400kg/m² walkway |
| Upright Column Profile | 55mm × 47mm × 1.5mm / 1.8mm | 75mm × 60mm × 1.8mm / 2.0mm | 80mm × 60mm × 2.0mm / 2.5mm reinforced |
| Pitch Adjustment Increment | 50 mm pitch | 50 mm or 75 mm pitch | 50 mm pitch |
| Decking Surface Types | SPCC Steel Panels / MDF Board | Pressed Ribbed Steel / Wire Mesh | Steel Grating / Perforated Decking |
| Optimal Application Scope | E-commerce fast pick, auto parts | Hardware, industrial machinery tools | High-clearance warehouse vertical mezzanines |
| International Compliance | ISO 9001:2015, RoHS | CE EN15512, ISO 9001:2015 | CE 2435-CPR-8605159, RMI Standards |
As global distribution operations scale amidst supply chain realignments, the requirements imposed on China racking manufacturers and exporters have migrated beyond simple dimensional tolerances to advanced technological integrations:
Medium duty bays are increasingly integrated with Autonomous Mobile Robots (AMRs). Chinese exporters engineer reinforced upright frames with standardized magnetic path tolerances and integrated barcode scanning clearance channels.
Freight cost stability dictates modular engineering. Racks are constructed with interlocking modular components that pack flush into standard 40-foot High Cube (40HQ) containers, reducing wasted shipping volume by up to 34%.
Strict environmental certifications mandate non-toxic, zero-VOC polyester powder coatings. Exporters align with European RoHS and REACH directives while improving salt-spray resistance benchmarks past the 500-hour barrier.
