OEM/ODM Types Of Racking Manufacturer & Suppliers

In modern supply chain engineering, specifying the correct warehouse storage infrastructure requires balancing volumetric storage density, SKU accessibility, pallet throughput velocity, and structural resilience. As a premier Chinese OEM/ODM racking manufacturer founded in 2001, Guangzhou Heda Shelves Co., Ltd. produces racking profiles designed in strict compliance with the Federation of European Material Handling (FEM 10.2.02), the Rack Manufacturers Institute (RMI MH16.1), and Australian Standard AS 4084-2012. Understanding the mechanical differences and metallurgical characteristics of each racking classification is vital for project engineers, logistics planners, and procurement directors looking to optimize total cost of ownership (TCO).

1. Selective Pallet Racking: The Universal Benchmark for High-SKU Distribution

Selective pallet racking remains the most widely deployed structural storage system globally, delivering 100% immediate selectivity to every individual pallet location. Fabricated from cold-formed omega-profile upright columns and heavy-duty step- or box-beams, this configuration accommodates standard counterbalance, reach, and VNA (Very Narrow Aisle) lift equipment.

• Structural Member Profiles: Uprights range from 80mm × 60mm to 120mm × 95mm with steel thickness varying from 1.5mm to 2.5mm depending on vertical bay loads and seismic zone parameters.
• Beam Connections: Cold-stamped 3-claw or 4-claw connector brackets engineered with integrated safety locking pins prevent accidental beam dislodgement under high-velocity forklift vertical impacts.
• Optimal Floor Layout: Aisle widths vary from 3,200mm to 3,800mm for conventional counterbalanced trucks, or down to 1,650mm to 1,900mm in turret-truck guided VNA designs, reducing wasted floor space while preserving single-pallet picking agility.

2. Double Deep Pallet Racking: Strategic Density with Pantograph Reach

By positioning two rows of standard selective racking back-to-back, double deep racking reduces dedicated forklift access aisles by approximately 50%, resulting in a 30% to 35% net increase in overall cubic storage capacity. Serviced by specialized pantograph-reach or articulating forklifts, double deep systems are optimal for operations handling multiple pallets per unique SKU under a First-In, Last-Out (FILO) stock rotation strategy.

• Structural Reinforcement: Lower level guide rails and heavy-duty frame row spacers ensure operational alignment, absorbing dynamic lateral forces when the reach mechanism is extended at elevation.
• Pallet Support Bars: Heavy-duty roll-formed top-hat or channel pallet support bars are standard to bridge depth variations and support under-dimensioned wooden or plastic skids.

3. High-Density Drive-In and Drive-Through Systems

Drive-In racking is engineered for maximum space conservation by eliminating intermediate operating aisles. Forklifts enter the rack’s physical bays to deposit or retrieve unitized loads supported on continuous structural cantilevered rails. Drive-In arrangements operate under FILO principles with a single access face, whereas Drive-Through configurations offer entry at opposing ends to facilitate FIFO inventory circulation.

• Absence of Cross-Beams: Because inner load levels do not feature structural cross-beams, drive-in systems rely on heavy-duty overhead portal ties, top horizontal cross-bracing, and rear vertical spine bracing to maintain spatial stability against racking sway.
• Impact Shielding: Continuous floor-anchored steel guide angles protect structural upright columns from repetitive mast and chassis friction during entry cycles.

4. Automated Radio Shuttle Pallet Racking: The Semi-Automated Benchmark

Radio shuttle storage represents the cutting edge of deep-lane consolidation. Pallet carriers move autonomously within deep structural storage channels, directed via industrial RF tablets or linked Warehouse Management Systems (WMS). Lift trucks operate solely at the pick/drop interface bay, significantly reducing forklift travel distances and eliminating collision exposure inside the rack superstructure.

• Cold Store Efficiency: Shuttle systems excel in sub-zero frozen warehouses (-25°C to -30°C), where minimizing room volume directly drives electrical refrigeration savings.
• Speed and Throughput: Modern brushless DC shuttle carriers achieve operational speeds up to 1.0 m/s unladen, executing high-throughput batch pallet sorting with pinpoint laser and sensor positioning accuracy.

5. Heavy-Duty Cantilever Racking: Unobstructed Linear Storage

Engineered specifically for non-palletized, long-span structural materials such as structural steel tubing, rebar bundles, PVC pipes, lumber, and drywall panels, cantilever racks eliminate vertical front-column obstruction. Columns are manufactured from either heavy roll-formed profiles or heavy-gauge hot-rolled structural H-beams (HEA/HEB profiles) welded directly to high-capacity base plates.

• Articulated Pin Connections: Cantilever arms feature modular wedge-pin or high-tensile bolted connections, allowing vertical adjustment on 100mm increments while pivoting upward safely if bumped by lifting masts.
• Deflection Engineering: Arm capacities range from 300kg to beyond 3,000kg per arm, designed to maintain strict limit states where deflection does not exceed $L/250$ under full uniform static load.

6. Multi-Tier and Rack-Supported Mezzanines: Vertical Volumetric Maximization

Rather than expanding building foundations, structural steel and rack-supported mezzanines capitalize on vertical overhead clearance. By utilizing heavy-duty pallet rack upright frames as structural load-bearing vertical columns, these systems support intermediate floor platforms engineered for human order picking, modular offices, or automated sorting conveyors.

• Decking Architectures: Platforms feature zinc-plated open steel grating, solid ribbed steel deck plates, or fire-rated B-deck panels finished with high-density anti-wear particleboard.
• Code Compliance: Integrated stair towers, industrial handrails, safety kickplates, and self-closing pallet drop-gates comply with OSHA 1910 and international building code mandates.

Established in 2001 in Guangzhou, China, Guangzhou Heda Shelves Co., Ltd. has grown into an international leader in the manufacture of heavy-duty pallet racking, industrial shelving, and complex structural mezzanine platforms. We combine massive manufacturing throughput with direct consulting engineering:

• Direct Factory Pricing & High Capacity: Operating a modern 30,000 m² workshop staffed by 300+ skilled technical employees, our automated cold roll-forming and robotic welding cells produce over 30,000 tons of structural steel storage equipment per month.
• Free Engineering & 3D Modeling: Our dedicated structural engineering team provides complete 2D CAD floor layouts, static load calculation sheets, and 3D warehouse renderings within 24–48 hours, free of charge, before financial commitment.
• Tropical-Grade Surface Finishing: Every component undergoes an exhaustive 7-stage pre-treatment bath (degreasing, pickling, rinsing, neutralizing, phosphating, and deionized wash) prior to automated electrostatic epoxy-polyester powder coating. This prevents rust, blistering, and flaking in humid tropical climates across ASEAN and coastal regions.
• Fast Sea-Freight Transit from Guangzhou: Direct shipping routes from Nansha or Huangpu ports ensure rapid delivery across major international ports: Vietnam (2-5 days), Philippines (3-5 days), Singapore & Thailand (5-7 days), Malaysia (6-8 days), and Indonesia (7-10 days).
