Warehouses serving diverse industries rarely handle single material types. A typical day might involve receiving steel pipes from a domestic mill, storing plastic conduit for an electrical distributor, and staging treated timber for a construction framing contractor. Each material presents unique storage requirements regarding weight distribution, surface sensitivity, and dimensional stability. Herochu addresses this operational reality through the Adjustable Heavy Duty Arm Steel/Plastic/Timber Storage System, a cantilever-based solution that adapts to mixed inventory without compromising storage density or access efficiency.

The adjustable arm mechanism serves as the system’s cornerstone. Unlike fixed-arm racks that permanently allocate vertical space, Herochu’s design incorporates a tapered locking interface between arm and column. Operators adjust arm heights by loosening a single locking bolt, sliding the arm to the desired position along a continuous slot or pre-drilled hole pattern, and re-tightening. The adjustment range spans the full column height at increments of 50 to 100 millimeters, enabling precise vertical positioning matched to material dimensions. For facilities storing 50-millimeter steel bars one week and 200-millimeter plastic pipes the next, this adjustability prevents wasted cubic volume between arm levels.

Material-specific arm configurations optimize support conditions. For steel pipes and heavy steel sections, standard heavy-duty arms with flat or slightly concave supporting surfaces provide full contact across the pipe diameter. The steel-on-steel interface transfers loads efficiently but may require protective liners when surface finish matters. Herochu offers optional polyurethane or rubber arm pads that cushion steel pipes, preventing coating scratches or galvanized finish damage during storage and retrieval. These pads compress slightly under load, conforming to pipe contours for enhanced stability while adding only millimeters to overall arm height.

Plastic pipe and conduit storage demands different considerations. Plastic materials weigh significantly less than steel equivalents but prove more susceptible to deformation under concentrated loads. Herochu’s adjustable arms for plastic storage incorporate wider support surfaces that distribute weight across a larger pipe contact area. The extended support width prevents point loading that could ovalize thin-wall conduits or leave permanent flat spots on PVC pipes. Arm surfaces receive smooth powder coating or optional nylon covers that slide easily under plastic materials without abrasive contact that might create stress risers or cosmetic damage.

Timber storage presents its own engineering challenges. Lumber weight varies substantially by species and moisture content, with green treated timber weighing considerably more than kiln-dried dimensional lumber. The adjustable heavy-duty arm system accommodates timber storage through reinforced arm profiles with capacity ratings verified for both concentrated and distributed loads. Arm spacing for timber storage typically matches standard unit lengths of 2.4 meters, 3.6 meters, or 4.8 meters, with multiple arms per bay supporting each timber bundle at several points along its length. This multi-point support prevents sagging or warping during extended storage periods, maintaining lumber straightness for downstream processing.

Load capacity per adjustable arm reaches 6 tons as standard, with customization available for facilities requiring higher thresholds. This capacity rating applies regardless of material type—steel, plastic, or timber—giving warehouse managers confidence that any material within the weight limit stores safely. What changes with material type is not the arm’s structural capability but rather the appropriate arm covering, spacing, and configuration. Herochu engineers consult with each customer to specify optimal arm types based on material mix, turnover frequency, and damage sensitivity.

The storage system’s overall length extends from 3000 millimeters to 12000 millimeters or more through custom engineering. Multi-bay configurations connect individual rack sections end-to-end, creating continuous storage rows that maximize linear storage capacity. For long materials such as 12-meter steel beams or 10-meter timber joists, the ability to span across multiple bays without intermediate obstructions proves essential. Herochu’s design includes alignment brackets and splice plates that maintain column spacing accuracy across extended runs, preventing the cumulative dimensional errors that complicate automated retrieval systems.

Corrosion-protected and powder-coated steel construction ensures longevity across all material storage applications. Powder coating provides excellent resistance against moisture, chemical exposure, and physical abrasion. The coating process applies to all exposed surfaces including columns, arms, braces, and hardware, eliminating unprotected edges where corrosion might initiate. For timber storage facilities where treated lumber leaches copper-based preservatives, the powder coating forms an impermeable barrier preventing chemical contact with base steel. Plastic storage facilities benefit similarly from corrosion resistance that eliminates rust staining on white or light-colored conduit.

Multilayer structural design within the adjustable arm system creates vertical storage opportunities without compromising floor-level operations. Standard configurations include two to four tiers above floor level, with each tier accessible from the aisle. The skeletal construction approach minimizes visual obstruction while providing robust stability under heavy loads. Diagonal bracing between columns transfers horizontal forces from crane operations or seismic events, maintaining structural integrity even when upper tiers carry full capacity while lower tiers remain empty.

Operational efficiency improves through 100 percent accessibility to any stored item. Unlike block stacking where materials must be reshuffled to reach lower layers, each pipe or timber bundle in the adjustable arm system sits directly accessible from the aisle. Forklift operators pick any item without moving other materials, reducing retrieval time by approximately 80 percent compared to nested storage methods. For high-turnover operations such as just-in-time delivery warehouses, this accessibility translates directly into faster customer order fulfillment and reduced labor costs per unit shipped.

Herochu’s installation support includes on-site guidance and online orientation for warehouse teams. The modular design allows phased implementation where facilities install adjustable arm bays incrementally as budget and space permit. Each bay operates independently while integrating seamlessly with adjacent bays through common aisle alignment and consistent arm height references. Color customization options help facilities implement visual management systems—red arms for steel storage, blue arms for plastic, green arms for timber—enabling operators to identify correct storage zones at a glance. ISO9001 and CE certifications accompany each system, providing documented quality assurance for procurement and safety compliance.
