Long Items Always Struggle to Find a Good Place to “Rest”—A Look at Cantilever Racking

If you take a walk through the warehouse of a pipe supplier or a profile processing plant, you’ve likely seen this scene: steel pipes several meters long leaning against a corner, propped up on two wooden blocks; stacks of sheets neatly stacked on the floor—to retrieve the one in the middle, you have to move everything on top first. It’s not that the owners don’t want to manage things properly; it’s just that these long materials simply won’t “fit” on standard shelving—they don’t fit on pallets, and the beam spans aren’t long enough. As a result, long materials often end up in haphazard corners of the warehouse, where they take up space, get damaged, and are difficult to locate.

I. The Challenge with Long Materials Lies Not in Their Weight, but in Their “Length”

Standard warehouse shelving is designed around pallets, and there are only a few standard pallet sizes. Steel pipes five or six meters long won’t fit horizontally, and storing them vertically makes retrieval difficult. Stacking them diagonally against a wall may seem convenient, but it actually comes with several drawbacks: the higher the stack, the more likely the materials at the bottom are to be crushed and deformed; retrieving items requires digging from the outside in, which is time-consuming and poses safety risks; and when different specifications are mixed together, finding a specific piece often takes a long time.

II. Cantilever Racking: Providing an Open Support System for Long Materials

The concept behind cantilever racking is straightforward: “cantilevers” extend from the uprights, and long materials are placed directly on them, with no uprights or crossbeams obstructing the front view. This allows full-length pipes, profiles, bars, and sheets to be stored lengthwise, enabling forklifts or workers to access them directly from the front—without having to navigate through the racking or cut materials to fit pallets.

Combined with adjustable cantilever levels, materials of different diameters and specifications can be organized by layer and zone, allowing users to locate items at a glance. For warehouses dealing in pipes, profiles, and sheet metal, this often transforms “that pile of materials in the corner” into “neatly organized storage bays.”

III. It’s Not Just a Matter of Placing Items Anywhere—Understand These Prerequisites

First, the cantilever arm length must match the material length. When materials are placed between two cantilever arms, if the overhang at either end is too long, the materials are prone to sagging, which also puts undue stress on the cantilever arms. When selecting a model, calculations should be based on the longest and heaviest items in the stock, rather than just the most common scenarios.

Second, extra-long or extra-heavy materials require separate evaluation. The heavier a single piece of material is, the higher the requirements for the cantilever arms, uprights, and floor anchoring; some exceptionally heavy or long materials may not be suitable for standard cantilever structures and may require reinforced structural solutions; one cannot simply assume that others’ approaches will work here.

Third, allow for operational space. Retrieving materials from high-level cantilever racks typically requires forklifts, so aisle width, forklift turning radius, and the routing of fire lanes must all be considered during layout planning—under no circumstances should fire lanes be obstructed by racks or materials; this is a fundamental rule of common sense. Don’t wait until the racks are installed to discover that while materials can be brought in, forklifts can’t maneuver.

Four: Measure the space first, then determine the plan

The specifics to clarify for a long-material warehouse are actually quite concrete: the approximate length range of the materials, the approximate weight class of individual heavy items, the frequency of daily material retrieval, and how much space can be allocated for forklift aisles and fire lanes. Without these figures, selecting a design based solely on intuition is likely to lead to mistakes.

Shibang Racking has been in the steel warehouse racking industry for many years, offering a full range of products including cantilever, heavy-duty, medium-duty, and mezzanine systems. We can tailor a solution to your specific materials and space—using cantilever racks where they’re needed and ensuring adequate aisle space where required. If you’re unsure, have them come out to take measurements and draw up a layout plan that clearly marks the storage zones, aisles, and cantilever clearance heights—this is far more reliable than just sketching it out on paper yourself.

Long materials are inventory too, and they deserve a designated, organized space.
