Rebar bundles reaching 12 meters in length create storage problems that standard cantilever racks cannot solve. The material is heavy, unwieldy, and prone to rolling when stacked incorrectly. Loading from only one side wastes aisle space and creates bottlenecks when multiple operators retrieve material simultaneously. Herochu’s Heavy Duty Double-Sided Steel Rebars 12 m Storage Rack addresses these constraints through a central-upright architecture that serves two access faces without duplicating structural framework.

Dual-Access Geometry

The double-sided configuration positions a single column of uprights at the rack centerline, with cantilever arms extending outward on both sides. This arrangement delivers several operational advantages over two single-sided racks placed back-to-back. First, it reduces the total steel required for the same storage capacity, lowering material cost. Second, it eliminates the gap between adjacent racks that accumulates debris and creates a hiding place for damaged or misplaced stock. Third, it allows operators to work from either side of the rack, reducing travel distance in high-throughput bays.

For 12-meter rebar bundles—the standard length for infrastructure and large-scale construction applications—the double-sided format provides continuous support across the full span. Multi-bay configurations extend horizontally as inventory grows, with each bay adding capacity without requiring a new structural footprint.

Load Capacity and Structural Design

Each compartment supports 3 to 5 tons, depending on configuration. The 12-meter model (HC-G12065) delivers 5 tons per level across six customizable layers, providing substantial capacity for bundled rebar. The Q235B high-strength steel frame features a dual-beam crossbar design that distributes load across two parallel beams rather than concentrating it at a single midspan point. Beam deflection under full load drops by approximately half compared to single-beam arrangements, maintaining structural stability as the load center shifts during loading and retrieval.

The frame construction uses structural-grade steel with reinforcement at critical junctions. X-braced spine members and pre-drilled footplates ensure stability under full seismic or forklift impact loads. Arms are available in 150 mm or 200 mm channel sections with reinforced gussets. Removable pin-stops lock rebar bundles in place during crane lifts, preventing the rolling motion that makes round stock hazardous to handle.

Classified Storage Architecture

Effective rebar management requires more than structural capacity—it demands organization. Herochu’s double-sided rack provides independent compartments per tier, with dedicated storage on both sides of the central upright. This architecture allows classification by rebar diameter, grade, or project allocation. A single bay might store #5 grade 60 rebar on the left side and #8 grade 75 on the right, with each compartment independently accessible.

For operations tracking heat numbers or mill certificates, the open cantilever design provides visibility of bundle tags from either aisle. Operators confirm material identity before initiating a lift, reducing the risk of installing incorrect stock. The clear separation between compartments also prevents bundles from different heats from commingling, a persistent problem with floor stacking or shared rack positions.

Loading and Retrieval Efficiency

The double-sided configuration supports simultaneous loading and retrieval operations from opposite faces, effectively doubling throughput in busy bays without additional equipment. A forklift servicing the left aisle can retrieve material while a crane operator works the right face, with no interference between the two activities.

For facilities using overhead cranes, the open-front geometry provides unobstructed hook access to every compartment. The crane descends directly onto the exposed bundle without threading through narrow openings or maneuvering around structural members. Pin-stops release after the load is rigged, allowing the bundle to lift cleanly.

The 12-meter span receives continuous support from multiple arm positions along the rack length. Unlike cantilever designs where deflection increases toward the unsupported end, the double-sided configuration balances load across the central spine, maintaining dimensional stability across the full 12-meter span.

Safety Features for Heavy Long Stock

Heavy rebar bundles create unique safety hazards. A 5-ton bundle that shifts during retrieval can crush equipment or personnel. Herochu addresses these risks through multiple design features. The low center of gravity—with loading heights starting at 300 mm—reduces the energy released if a bundle shifts during handling. Arms are laser-engraved with safe working load tags, and a built-in deformation indicator signals when overload or impact has occurred, alerting maintenance before structural compromise develops.

The dual-beam crossbar design contributes to safety by maintaining arm level under load. When a 5-ton bundle rests on a cantilever arm, the load creates a rotational force at the arm-column connection. The dual-beam arrangement resists this force more effectively than single-beam construction, keeping the arm horizontal and preventing the bundle from rolling toward the aisle.

Customization and Compliance

Herochu manufactures the Heavy Duty Double-Sided Steel Rebars 12 m Storage Rack in ISO 9001-certified facilities with CE compliance. Standard models accommodate 6000, 9000, and 12000 millimeter lengths, with custom dimensions available. The number of layers ranges from 4 to 6 as standard, with higher configurations available based on ceiling clearance. Clear space per tier is customizable, accommodating bundled or loose materials.

For operations managing 12-meter rebar at volume, the double-sided rack delivers the combination of density, access, and structural integrity that single-sided alternatives cannot match. The central-upright design reduces footprint while maintaining the capacity of two separate racks, and the dual-access geometry eliminates the bottleneck of single-side retrieval.
