Custom OEM Drive In Racking System Factories & Suppliers

Drive-In racking is engineered specifically for facilities handling large pallet volumes of identical Stock Keeping Units (SKUs) with moderate-to-low item selectivity requirements. The ideal operational profile features fewer than 50 distinct SKUs, where entire lanes (ranging from 4 to 12 pallets deep) can be dedicated to a single production batch or shipment lot. Typical industries include cold storage and frozen meat/vegetable distribution, bottled water and carbonated beverage manufacturing, chemical raw material staging, seasonal agricultural packing (such as date and fruit processing), and building materials.

Conversely, if your warehouse operates an e-commerce fulfillment or retail distribution model requiring immediate, direct pick access to thousands of discrete individual SKUs, standard Selective Pallet Racking or Very Narrow Aisle (VNA) racking is technically superior. Double Deep racking serves as an intermediate hybrid, reducing aisles by 50% while maintaining 50% immediate pallet selectivity using pantograph reach trucks.

Progressive collapse prevention in Drive-In engineering relies on creating an integrated three-dimensional structural diaphragm. Because the interior lanes must remain open for forklift access, traditional front-to-back crossbeams are omitted. HEDA mitigates longitudinal and lateral frame buckling through a three-tier reinforcement strategy:

1. Top Horizontal Plan Bracing: Heavy diagonal steel angles form a continuous horizontal truss network across the entire ceiling plane of the racking block, transferring lateral racking loads directly to the outer perimeter frames.
2. Rear Vertical Tower Bracing: The back of each bay is reinforced with heavy vertical cross-tension rods and structural steel channels, forming a rigid spine that anchors the entire block against forklift thrust loads.
3. Heavy-Duty Front Leg Column Guards: Structural wrap-around floor bull-nose protectors (12mm steel) are bolted independently to the concrete floor slab with elastomeric dampening pads. This isolates the vertical column from impact shocks caused by forklift wheels or pallet corners entering the lane.

Precise clearance calculations are critical to prevent pallets from dislodging or catching on upright flanges. Standard design guidelines adhering to FEM 10.2.02 and RMI standards specify:

• Pallet Overhang & Seat: The pallet must bear continuously on the support rail with a minimum bearing width of 50mm to 65mm per side. For standard 1200×1000mm pallets, the nominal lane clear entry dimension between rail lips is typically engineered at 1050mm–1100mm.
• Vertical Tier Clearance: A minimum clearance of 100mm to 150mm must be maintained between the top of the loaded pallet unit (including stretch wrap bulge) and the underside of the support bracket above it to allow easy lifting and extraction.
• Forklift Dimensions: The maximum overall width of the forklift truck (including outriggers and cab guards) must be at least 150mm to 200mm narrower than the clear width between the floor guide rails. Counterbalanced forklifts, articulated reach trucks, and stand-on reach trucks must be specified with narrow-chassis configurations and mast profiles that do not flare past the outer chassis line.

Warehouses across the Gulf region (UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, Oman) enforce strict municipal Civil Defense fire codes and seismic regulations. HEDA’s design engineering team prepares full technical calculation submittal dossiers that address these requirements directly:

• ESFR Sprinkler Clearance: Our 3D CAD layouts ensure that upper storage tiers maintain a continuous unhindered clearance of at least 900mm to 1000mm below the lower chord of structural roof trusses and ESFR sprinkler deflector heads.
• Transverse Flue Spaces: In long drive-in runs, we incorporate dedicated 150mm–300mm longitudinal flue spaces and vertical ventilation gaps to allow radiant heat to rise freely to activate thermal bulb sprinklers and facilitate rapid fire suppression.
• Seismic Ground Acceleration: In accordance with local building codes, structural upright profiles, baseplate surface areas, and anchor bolt embedment depths are calculated against horizontal seismic coefficient forces ($S_s$ and $S_1$) to prevent anchor pullout or frame plastic hinge failure during earth tremor events.

Environmental conditions dictate metallurgical coating longevity:

• Sub-Zero Cold Storage (-25°C to -30°C): While humidity inside steady freezing rooms is low, rapid condensation and thermal shock occur during system defrosts and near air-curtain loading doors. HEDA utilizes a high-adhesion pure polyester electrostatic powder coating (80–100μm) pre-treated with zinc phosphating to prevent micro-blistering. In ultra-humid blast freezers or wet meat-processing environments, we recommend Hot-Dip Galvanizing (HDG) to EN ISO 1461, providing a sacrificial zinc layer of 60–85μm that resists rust even if physically scored by pallet corners.
• Coastal Desert Conditions (Jebel Ali, Dammam, Jeddah): High ambient temperatures combined with high saline sea air rapidly degrade standard industrial paints. Our 12-stage automated pre-treatment line completely strips mill-scale and oil, applying an inorganic conversion coating that prevents rust undercutting, validated by standard 500-hour ASTM B117 salt spray testing.

Typical factory production lead time is 15 to 25 business days from final CAD layout sign-off and structural approval. For project logistics, our factory implements rigorous container packing protocols: upright frames are nested with wooden dunnage dividers and heavy steel strapping to prevent in-transit maritime chafing; beams and rails are packaged in color-coded, labeled bundles that match the project's erection drawings.

Every shipment includes detailed 3D step-by-step assembly blueprints, torque specification charts, and parts lists. HEDA provides comprehensive remote video engineering supervision for your local installation crews, and can dispatch dedicated bilingual site engineers for on-site structural erection supervision on large multi-tier projects.

Honeycombing refers to the unoccupied void spaces that occur inside a deep drive-in lane when pallets from that lane have been partially dispatched. Because a LIFO lane can only store one SKU, you cannot place a different product in front of an existing SKU without completely blocking access. In real-world multi-SKU operations, honeycombing frequently reduces effective theoretical storage capacity by 20% to 35%.

If your operation experiences high inventory velocity where individual lanes cannot be rapidly cleared and replenished as complete batches, or if forklift travel times deep into lanes create operational bottlenecks, upgrading to a Radio Shuttle Racking System is highly cost-effective. Shuttle systems operate at lane-level FIFO or LIFO without the forklift ever entering the rack bay, slashing cycle times by up to 50% and completely eliminating structural upright collision risks.
