High-Density Rack Systems

Engineered dynamic racking and high-density storage solutions designed to maximize space efficiency, throughput velocity, and ROI for global B2B operations.

Custom Industrial Racking

Engineered Rack Systems Portfolio

Elevate your operational efficiency with engineered rack systems tailored by FlexBeam Warehouse Equipment Co., Ltd. Our systems integrate heavy-duty structural steel components with dynamic flow technology to solve complex warehouse storage challenges.

High Density · LIFO

SK3600® Pushback Rack System

The SK3600® Pushback system stores pallets 2 to 5 deep on nested carts riding on inclined structural rails. Each storage lane operates independently, boosting storage capacity by up to 90% compared to standard selective racking while retaining swift SKU access.

  • High-density LIFO inventory control
  • Heavy-duty nested cart design
  • Resists pallet jamming and damage
  • Ideal for medium-velocity multiple SKUs
Gravity Flow · FIFO

SK3400® Pallet Flow Rack System

Utilizing gravity flow lanes equipped with self-energized speed controllers, SK3400® dynamic racking automatically moves loaded pallets from the charge aisle to the discharge aisle, ensuring flawless First In, First Out inventory management.

  • Full FIFO inventory rotation
  • Integrated speed controllers & safety brakes
  • Maximizes floor cube utilization
  • Optimal for food, beverage & perishables
Maximum Density · Cold Storage

Drive-In & Drive-Through Racking

Drive-In rack systems eliminate traditional aisles, enabling forklift trucks to drive directly into storage bays to store pallets multiple positions deep. Constructed from structural steel channels to handle rigorous daily forklift traffic.

  • Lowest cost-per-pallet position for dense storage
  • Heavy-duty structural channel arms & rails
  • Proven performance in freezer environments
  • Best suited for uniform high-volume SKUs
Automated Storage · High-Bay

AS/RS Automated Racking Systems

In Automated Storage and Retrieval Systems (AS/RS), racking serves as the core structural backbone. FlexBeam engineers structural racking to strict tolerances, maintaining deflection alignment under continuous crane cycles and dynamic loads.

  • Engineered for automated crane integration
  • Structural steel channel posts resist fatigue
  • Precision beam connections for high-bay stability
  • Protects long-term automation investment
Fulfillment · Multi-Level

Warehouse Pick Modules

Multi-level order picking structures combine dynamic pallet flow, carton flow, and integrated conveyor systems. Engineered to speed up piece and carton fulfillment while optimizing vertical warehouse space.

  • Integrates flow rack, mezzanine & conveyors
  • Accelerates high-velocity order picking
  • Custom floor grating & safety gates
  • Scalable footprint for e-commerce fulfillment
Modular Structural · Bolted

SK ADVANTX™ Modular Bolted Rack

A modular structural steel racking system utilizing heavy-duty structural channel posts and bolted bracing. Offers exceptional rigidity, economical container freight loading, and fast on-site field adjustability.

  • Modular bolted structural channel frame
  • Cost-effective containerized export packaging
  • High resistance to forklift impact
  • Scalable frame heights & depth configurations
Semi-Automated · Deep Lane

Pallet Shuttle Systems

A semi-automated deep lane storage solution utilizing remote-controlled shuttles to carry pallets deep inside racking channels. Eliminates forklift aisle travel inside lanes, dramatically increasing throughput speed and storage density.

  • Deep lane automated shuttle carriage
  • Operates in LIFO or FIFO configurations
  • Reduces forklift driver travel times
  • Ideal for cold storage & high-volume logistics

Engineering FAQ

Frequently Asked Questions

Essential guidance for international procurement managers, facility planners, and warehouse automation integrators.

High-density dynamic rack systems (such as Pushback, Pallet Flow, and Drive-In) eliminate aisle space by storing pallets 2 to 6+ deep. This increases overall storage density by up to 75%–90% within the same warehouse footprint, significantly lowering per-pallet storage costs for high-volume operations.

FlexBeam engineers AS/RS racking using heavy-duty hot-rolled structural steel channels manufactured to strict tolerances. Our structural designs resist deflections under dynamic crane loads, continuous cycling, and seismic forces, maintaining system alignment for long-term automated operations.

Yes. Cold storage space is costly per cubic meter. FlexBeam structural steel Drive-In, Pushback, and Shuttle rack systems are heavily utilized in freezer and refrigerated warehouses due to their impact resistance, dense cube utilization, and durable powder-coated or galvanized finishes.

All FlexBeam industrial rack systems are engineered in reference to international design codes including ANSI MH16.1 (RMI), EN 15512, and AS 4084. Every system is shipped with certified load capacity calculations, component coding, and installation assembly drawings.
