Is Drive-in Racking the Right Solution for Your Warehouse Density and Cost Targets?

Drive-in racking relies on cantilevered side rails supporting the outermost inches of the pallet bottom. Therefore, pallet standardization is vital. Uniform 48" x 40" GMA pallets, solid CHEP four-way blocks, or Euro standard wood/plastic pallets work best. Pallets must not exhibit broken base runners, cracked deck boards, or excessive sag. Beam deflection under full live load must be engineered not to exceed 1/200th of the span, ensuring forklifts do not catch pallet undersides during transit.

From an initial capital expenditure (CAPEX) standpoint, drive-in racking is approximately 40% to 60% less expensive per pallet position than semi-automated shuttle systems because it contains no motorized vehicles, batteries, or software interfaces. However, pallet shuttles often deliver lower operational expenditure (OPEX) in 24/7 or high-throughput facilities by cutting forklift cycle time by up to 50% and virtually eliminating forklift-to-frame collision damage inside storage lanes.

Yes. NEDCON Storage Racking Solutions B.V. designs structural steel configurations referencing ANSI MH16.1 (RMI) standards in the USA and CSA A344 in Canada. In high-seismic regions (such as coastal California or the Pacific Northwest), our structural engineers implement heavy-duty top-tie portal beams, oversized anchor baseplates, thick column gauges, and robust back-plane cross-bracing to resist ground acceleration forces and achieve full municipal building permits.

Because forklifts enter directly between uprights, drive-in racking requires dedicated impact defense: (1) Continuous heavy-duty floor-mounted guide rails (structural angle iron or tube) that physically steer the forklift wheels down the center of the bay; (2) Flared steel lead-in shoes at the entry columns; and (3) Heavy wraparound column protectors reinforced with high-density rubber dampening to isolate energy from the structural uprights.

While systems can physically be engineered 10 to 12 pallets deep, the operational optimum for manual forklift operation is between 4 and 8 pallets deep. Beyond 8 pallets deep, reversing trucks through long tunnels becomes slower, driver fatigue increases, and risk of accidental rail collisions escalates. When operational requirements exceed 8 pallets deep, NEDCON recommends evaluating semi-automated pallet shuttle configurations.

In accordance with NFPA 13 and local building codes, deep-lane rack storage of combustible materials or plastic pallets often necessitates in-rack sprinkler lines. NEDCON designs specialized internal pipe support brackets protected behind the vertical uprights and beneath the pallet support rails, ensuring lift truck masts and pallet loads cannot snag sprinkler heads during entry or retrieval.
