Heavy duty pipe storage rack for 120 dia tubes & rod 50 to 120 dia

What rack structure safely holds 120mm diameter tubes and rods from 50 to 120mm?

Large-diameter tubes and solid rods present a different challenge than thin-wall pipe. A 120mm diameter steel tube can weigh several hundred kilograms per meter, and solid rods in the 50–120mm range are denser still. The heavy duty storage rack for 120 dia tubes & rod 50 to 120 dia must be engineered around the concentrated point loads these materials create on the arms.

Herochu’s heavy-duty cantilever series is built for this category. The upright columns are fabricated from structural steel with bracing that prevents lateral sway under uneven loading—a critical consideration when a 120mm tube rests on one side of a double-sided rack and the other side is partially empty . The arms themselves are designed with a slight upward pitch when unloaded, so that deflection under maximum load brings them to level rather than drooping below horizontal . This detail matters for rod storage, where a downward-sloping arm encourages the load to creep forward.

How do end stops and arm design prevent round stock from rolling off?

Round tubes and rods are inherently unstable on flat supports. A slight bump from a forklift or a minor seismic event can start a roll that ends with several tons of steel on the floor. Herochu addresses this with removable end stops—steel pins inserted into the arm tips that act as a physical barrier . Unlike fixed lips that can interfere with loading, removable stops allow the operator to position them after the load is placed.

For rod storage specifically, the spacing between arms along the rack length must be tight enough to prevent the rods from bowing between supports. A 50mm solid rod over a six-meter span will deflect noticeably if supported at only two points. Herochu’s modular design allows additional towers or arm pairs to be added at intermediate positions, reducing the unsupported span and keeping the stock straight .

What steel grade and coating are used in Herochu heavy-duty racks?

Herochu constructs its heavy-duty cantilever racks from Q235 structural steel, a common grade in industrial racking with a well-defined yield strength suitable for load-bearing applications . The powder coating is applied electrostatically and cured to form a continuous film that resists rust, oil, and the general wear of a steel service center environment.

For facilities with outdoor storage or high humidity, this coating system provides meaningful protection, though buyers should note that no powder coat is indefinitely impermeable. Herochu’s documentation recommends periodic inspection of coated surfaces, particularly at weld seams and arm-to-upright connections where coating adhesion can be compromised by flexing under load . Touch-up paint is available for spot repairs, extending the service life of the rack.

How does the rack accommodate both 120mm tube bundles and smaller rods?

A single cantilever rack can be configured with different arm levels optimized for different stock types. Lower levels might use shorter, heavier arms designed for dense 120mm tube bundles, while upper levels use longer arms with closer spacing for smaller-diameter rods that require more support points . The tower uprights are common to all levels; only the arm specification changes.

This layered approach is more space-efficient than dedicating separate racks to each product type. It also reflects how steel distributors actually operate—a customer order might require pulling two 120mm tubes and a bundle of 60mm rods from the same rack, and the operator needs safe, clear access to both. Herochu’s adjustable arm positions allow this mixed-use configuration without compromising the structural integrity of any level .

What load testing and certification apply to these heavy-duty racks?

Herochu subjects every rack design to finite element analysis before fabrication, simulating the stress distribution under maximum rated load . This computational verification is followed by physical load testing on completed units before shipment. The company holds CE certification and manufactures under ISO9001 quality management standards, providing documented assurance that the rack meets recognized safety criteria .

For buyers specifying racks for 120mm tubes, the key document to request is the load chart showing capacity per arm at the specified arm length. Cantilever capacity decreases as arm length increases because the bending moment at the upright connection grows. A rack rated for 3 tons at 800mm arm extension may be rated for significantly less at 1,500mm. Herochu provides this data with each quotation so buyers can verify that the chosen configuration matches their actual loading conditions, not just the headline capacity figure .
