Steel service centers and fabrication shops face a persistent challenge: storing long stock efficiently without sacrificing access speed or material integrity. Herochu’s heavy-duty telescopic cantilever rack addresses this directly, engineered for steel bars, pipes, and angles in high-volume industrial environments. The system eliminates the fundamental flaw of traditional floor stacking—damage from ground contact, rust, and the labor burden of searching through disorganized bundles.

Structural Engineering and Load Performance

At the core of this rack is a Q235B high-strength steel frame with a dual-beam crossbar design. This configuration distributes concentrated loads across multiple structural members rather than concentrating stress at single attachment points. Each compartment supports between 3 and 5 tons, depending on model configuration. The HC-G6053S and HC-G6053 handle 6-meter stock at 3,000 kg per level, while the HC-G9065 and HC-G12065 accommodate 9-meter and 12-meter materials respectively at 5,000 kg per level.

The dual-beam crossbar deserves specific attention. In conventional cantilever designs, each arm attaches at a single pivot point. Under repeated loading cycles, that point gradually deforms, causing progressive arm deflection. Herochu’s dual-beam configuration adds a horizontal tie between adjacent arms on the same tier, transforming individual cantilevers into a load-sharing group. The result is predictable structural behavior under dynamic loading and arms that return to true position when unloaded.

Telescopic Operation and Space Efficiency

The telescopic mechanism extends arms by 70% to 99% of their retracted length. An operator cranks the arm outward, loads or unloads material, then retracts it. The movement path is constrained, eliminating the lateral drift that causes pipe bundles to swing into adjacent compartments during forklift or crane loading. This precision matters in dense storage environments where clearance is measured in centimeters.

The space savings are measurable. Traditional cantilever systems require permanent aisles wide enough for forklift access to every bay. Herochu’s telescopic design collapses that aisle requirement to the depth of one extended arm—typically under 1.2 meters. Facilities implementing this system report reclaiming 30% or more of their floor area for value-adding operations.

Independent Compartments and Classification Storage

Each tier is divided into independent compartments on both sides of the column. A 5-ton bundle of 150mm steel angles occupies one compartment; an adjacent compartment might hold smaller-diameter pipe or solid bar stock. This classification capability eliminates the mixing that occurs with open cantilever arms, reducing search time and preventing material damage from incompatible loads shifting against each other.

The system accommodates bundled and loose materials interchangeably. For bundled pipe arriving from the mill, the crane or forklift places the entire bundle onto the extended arm. For loose material or partial bundles, dividers within each compartment keep individual pieces organized without requiring separate storage locations.

Model Selection Guide

The HC-G6053S is a single-sided configuration for wall-mounted installations. All other models default to double-sided storage, doubling capacity within the same column footprint. Clear space between layers starts at 600mm and adjusts upward for oversized diameters or bundled loads.

Corrosion Protection and Longevity

The powder-coated finish covers all surfaces after fabrication—not merely visible areas. This matters in pipe storage environments where condensation from temperature swings, residual cutting fluid on machined ends, and general warehouse humidity attack unprotected steel. The coating provides corrosion resistance that extends service life and reduces maintenance, particularly in coastal or high-humidity facilities.

Hot-dip galvanizing is available as an option for outdoor yards or semi-enclosed sheds. The sacrificial zinc layer protects the underlying steel even when the surface is scratched during loading—a realistic scenario when heavy bundles slide across arm surfaces.

Application Scenarios

Herochu’s telescopic cantilever rack serves mechanical processing shops, building materials distributors, and small-to-medium manufacturing operations. A fabrication shop storing 6-meter angle iron for structural weldments uses the HC-G6053 with four roll-out levels plus one fixed top level. A pipe distributor handling mixed 6-meter and 9-meter stock selects the HC-G9065 as a bridge model—the 5-ton rating matches the longer frame’s capacity without the full 12-meter investment.

For operations transitioning from floor stacking or rented warehouse space, the rack’s modular expansion capability means the initial investment does not lock the buyer into a fixed footprint. Additional column sections and arm sets extend an existing row without disturbing installed structure.
