Explore our certified cold-rolled pallet racking architectures, modular cross-beam assemblies, and integrated industrial storage platforms engineered for maximum structural equilibrium.
The cross beam represents the fundamental horizontal load-bearing component in selective, drive-in, VNA, and automated shuttle racking infrastructures. In modern structural warehouse design, failure modes are predominantly driven by vertical flexural bending, lateral torsional buckling, and connector rotational stiffness at the upright interface. To satisfy stringent CE structural criteria—specifically EN 15512:2020 (Steel static storage systems - Adjustable pallet racking systems - Principles for structural design)—pallet cross beams must be calibrated against rigorous deflection ratios, weld shear parameters, and cold-formed profile yields.
HEDA Shelves manufactures dual-profile cross beams through automated continuous roll-forming lines. The primary heavy-duty architecture utilizes two cold-formed "C" profiles nested and seam-welded by high-precision robotic MIG stations to create a continuous tubular box section. This geometry provides superior Section Modulus ($Z_x$) and Polar Moment of Inertia ($J$), drastically mitigating horizontal deflection when subject to dynamic pallet placement.
For applications integrating timber shelving panels, flush galvanized steel decks, or drop-in wire mesh decking, step beams are engineered with an interior 20mm to 25mm structural recess. This enables smooth pallet transfer while preventing snag hazards during forklift entry and retraction.
The structural performance of a cross beam is dictated not merely by its central profile, but by the mechanical interlock between its end connectors (beam claws) and the column teardrop/diamond punching. Our beams incorporate 3-claw, 4-claw, and 5-claw high-ductility cast or stamped steel connectors designed to induce semi-rigid frame behavior ($M-\theta$ curve stabilization).
Every connection is fortified with an independent safety locking pin capable of resisting unintended vertical dislodgement forces exceeding 5 kN, exceeding OSHA and EN 15635 compliance benchmarks.

Intralogistics is transitioning toward higher automation densities, extreme weather resilience, and smart traceability. Forward-looking procurement teams are adjusting their material requisitions to match three dominant engineering vectors.
Standard manual forklift racks permit an elastoplastic deflection ratio of $L/200$. However, the massive surge in autonomous mobile robots (AMR) and Automated Storage and Retrieval Systems (ASRS) necessitates stiffened cross-beam profiles rated at $L/300$ or $L/400$. Even millimeter-scale deflection can blind robotic optical guidance sensors or cause shuttle carrier stalls. Global logistics developers are mandating ultra-low deflection beam matrices to safeguard robotic compatibility.
With international freight costs tied directly to steel tonnage, modern cross beam engineering emphasizes high-strength low-alloy (HSLA) steels. By replacing conventional low-carbon Q235B steel with micro-alloyed Q355B (yield strength ≥ 355 MPa), our engineers reduce cross-sectional wall thickness by 12% to 18% while expanding ultimate bending moments. This engineering leap lowers shipping container counts and structural slab point-loads without sacrificing static load capacities.
Regional cold-chain facilities operating down to -30°C face severe metal embrittlement risks. Procurement protocols now demand steel with certified Charpy V-notch impact toughness values at sub-zero temperatures. Simultaneously, coastal distribution hubs across Southeast Asia and the Middle East require multi-stage pre-treatments (pickling and zinc-phosphating) followed by 80-120μm thermosetting polyester electrostatic powder coatings or hot-dip galvanization (ISO 1461) to combat saline condensation.
Guangzhou Heda Shelves Co., Ltd. (founded 2001) operates a state-of-the-art 30,000 m² manufacturing complex, combining 25 years of structural metalworking with international engineering compliance.
From raw Baosteel/Shougang hot-rolled strip slitting to continuous 18-station roll-forming, automatic CNC punching, laser profiling, and multi-station robotic beam-claw welding, 100% of manufacturing occurs in-house. This centralized control prevents tolerance stack-up and ensures flawless claw-to-upright fit on site.
