Direct from our 30,000 m² automated production facility: custom structural pallet racks, high-density dynamic push-back systems, live gravity lanes, and certified industrial shelving built for global distribution networks.
Push back pallet racking is a dynamic high-density storage methodology operating on a continuous Last-In, First-Out (LIFO) inventory cycle. Unlike standard drive-in racking that necessitates forklift travel inside structural pallet lanes, push-back racking employs low-profile inclined steel tracks combined with multi-tiered nested rolling carts. The mechanical process relies strictly on structural gravity flow: when an initial pallet is deposited onto the top nesting cart, the forklift utilizes the second pallet to mechanically press the first cart backward along low-friction guide rails, exposing the sub-tier cart beneath it.
Our OEM/ODM push back installations operate across 2-deep, 3-deep, 4-deep, 5-deep, and 6-deep bay architectures. By restricting forklift movements entirely to the front structural aisle, push-back storage increases pallet capacity by 75% compared to selective racking while reducing rack transit cycle times by 40%. The elimination of mast entry into narrow racks virtually prevents column damage, minimizing operational risk and lifetime structural maintenance expenditures.
The operational safety and reliability of a push-back rack depend entirely on the track inclination ratio. At our manufacturing facility, rails are rolled and brake-formed to maintain an exacting slope gradient between 2.2% and 2.8% (1.25° to 1.6°). This tight geometric tolerance guarantees sufficient gravitational kinetic energy for pallets to roll smoothly toward the loading face without generating uncontrolled acceleration, impact shocks, or dynamic pallet displacement when rear unit loads advance.
Manufactured from cold-formed structural steel profiles with laser-welded cross-members. Nesting depths utilize stepped track profiles to conserve vertical bay clearances down to less than 150mm per cart cluster.
Machined from C45 carbon steel with double-sealed ABEC-5 industrial ball bearings. Engineered with continuous lateral flanges that eliminate cart crabbing, rail derailment, and friction binding under asymmetric loads.
Our OEM nested trays integrate structural secondary cross-flanges, accommodating standard Euro pallets (1200x800mm), Industrial pallets (1200x1000mm), and US GMA spec pallets (48"x40") without changing structural rail bases.

At Guangzhou Heda Shelves Co., Ltd., contract manufacturing and custom engineering represent our primary operational strengths. Because every industrial warehouse facility presents unique ceiling clearances, column spacing grids, concrete slab load deflection boundaries, and seismic criteria, standard catalogue racking frequently fails to maximize storage volume. Our engineering office delivers complete customized layout engineering—generating parametric 3D CAD models and structural calculations compliant with EN 15512:2020 (European Standard for Steel Static Storage Systems) and RMI ANSI MH16.1 within 24 to 48 hours of project brief receipt.
Our push back systems are fabricated from certified high-tensile Q235B and Q355B structural coil steel, procured strictly from premier tier-one domestic steel mills. Raw coils are subjected to spectrophotometric material analysis and yield-strength tension tests before entering the production line. Precision cold roll-forming ensures upright columns retain strict linear dimensional tolerances without residual internal torsion stresses.
Roll-formed up to 12 meters in seamless continuous lengths. Column section profiles from 80x60mm to 120x95mm with steel thicknesses from 1.5mm to 2.5mm.
Cart footprints engineered specifically to customer pallet tolerances, preventing deflection under point-loading from broken bottom deckboards.
Automated electrostatic lines applying thermo-hardened epoxy-polyester coatings (60-90µm thickness) in any custom RAL hue with UV and chemical barrier resistance.
Dedicated OEM exporter packing with barcoded component labeling, client brand markings, and seaworthy timber-reinforced container bundling.
Every structural beam, upright column, nested cart, and guide rail passes through our verified ISO 9001:2015 manufacturing process to ensure dimensional stability and load-bearing safety.
The global warehousing landscape is experiencing profound transformations driven by industrial real estate cost escalation, labor scarcity, sustainability mandates, and the rapid adoption of automated mobile robots (AMRs). As warehouse directors and supply chain engineers formulate capital expenditure budgets for the upcoming decade (2026-2035), push back pallet racking is adapting to align with complex dynamic supply chain environments:
With sub-zero warehouse space costing up to 300% more to cool than dry ambient facilities, high-density push back installations are increasingly deployed in -30°C freezer facilities. Procurement requires specialized low-temperature metallurgical steel formulations, cryogenic bearing greases, and stainless-steel guide wheel assemblies to eliminate thermal contraction seizing.
Modern distribution facilities are shifting from purely manual counterbalance forklift operations toward hybrid material handling ecosystems. Push back racking is being deployed as a dense gravitational buffering zone where Autonomous Counterbalanced Forklifts (AMRs) interface directly with the lower tier cart faces, automating high-throughput inbound staging lanes.
International environmental regulations, including the European Union's Carbon Border Adjustment Mechanism (CBAM), are transforming procurement criteria. HEDA Shelves is actively responding by incorporating electric arc furnace (EAF) steel feedstocks with certified carbon accounting, lowering embodied carbon per pallet position by over 32% compared to historical baselines.
