A comprehensive technical breakdown for intralogistics managers, structural specifiers, and global procurement officers seeking long-term operational safety, earthquake resistance, and ROI optimization.
Our medium and heavy duty racking uprights and beams are cold-roll-formed from premium certified strip steel. We leverage low-carbon micro-alloyed Q235B (yield strength ≥ 235 MPa, tensile strength 375–500 MPa) for standard ambient racking and high-tensile Q355B for high-bay structural frames and sub-zero cold chain deployments. This metallurgical composition prevents embrittlement while retaining optimal ductility under dynamic cyclic forklift impact.
In accordance with the Federation of European Materials Handling (FEM 10.2.02) and EN 15512 specifications, our beam design adheres strictly to a vertical deflection limit of L/200 (where L is the clear span distance between upright columns). Every system includes a minimum structural safety coefficient of 1.5 against ultimate yield load, safeguarding material handling teams against catastrophic frame collapses caused by localized load redistribution.
Corrosion mitigation begins with our automated 10-stage immersion or spray pretreatment, including high-temperature chemical degreasing, acid pickling to strip mill scales, and dynamic zinc phosphate coating. Electrostatic application of thermosetting TGIC-free epoxy-polyester powder (dry film thickness 60–90 μm) cured at 180°C–200°C ensures exceptional cross-hatch adhesion (ISO 2409 Class 0) and superior salt-spray corrosion tolerance for humid climates.

Global supply chains are undergoing structural transformations. Procurement teams are moving beyond basic unit cost toward Total Cost of Ownership (TCO), automation compatibility, and circular sustainability metrics.
Manual picking warehouses are transitioning rapidly into hybrid automated facilities. Medium duty racking profiles are being re-engineered with robotic guidance clearings, integrated optical fiducial tracking barcodes, and tighter deflection tolerances (L/300) to allow Autonomous Mobile Robots (AMRs) and robotic reach trucks to extract totes and nested cartons without mechanical jams.
Tenant leases in modern 3PL distribution parks are becoming shorter, demanding racking structures that disassemble, transport, and reconfigure within 48 to 72 hours. Bolted frame uprights combined with boltless connector safety clasps and clip-in steel decking have surpassed welded structures, reducing installation labor costs by up to 40% while preserving load rating certifications.
Global Fortune 500 corporations now enforce Scope 3 carbon auditing on warehouse supply equipment. Racking manufacturers are switching to scrap-based Electric Arc Furnace (EAF) low-carbon steel coils, solventless volatile-organic-compound-free (Zero-VOC) thermoset powders, and closed-loop phosphating washwater recycling systems that deliver full LEED v4.1 sustainability credits.

Direct answers to technical questions frequently raised by plant directors, facility engineers, and warehouse operations specialists.
The distinction lies in beam profile geometry, steel gauge, and intended handling equipment. Medium duty pallet racking is engineered for uniformly distributed loads ranging from 200 kg to 800 kg per level, primarily utilizing step beams (P-beams) or lightweight tube beams paired with steel decking, wire mesh, or particle boards for hand picking or light pallet handling. Heavy duty pallet racking utilizes heavy box beams or I-beams rated from 1,000 kg up to 4,500 kg per level, explicitly constructed for counterbalance or reach forklift operations.
For medium duty systems under 800 kg per level, concrete slabs typically require a minimum compressive strength of 20 to 25 MPa (C20/C25 grade) with a slab thickness of not less than 150mm. Each upright footplate is anchored using M10×80mm or M12×100mm mechanical wedge expansion anchors. If your facility possesses an unreinforced slab or asphalt substrate, our engineering department calculates custom load-spreading baseplates to distribute point pressure safely below the floor shear limit.
Our factory holds Factory Production Control (FPC) Certificate No. 2435-CPR-8605159 issued by an accredited European Notified Body under Construction Products Regulation (EU) 305/2011. We maintain comprehensive 100% material heat traceability, certified welding personnel (ISO 9606-1), documented welding procedure specifications (WPS/WPQR), and ultrasonic non-destructive testing on critical load-bearing joints. Every export container is accompanied by a formal Declaration of Performance (DoP) and CE marking label.
Yes, provided the structural uprights are pre-engineered with appropriate sectional thickness (minimum 1.8mm to 2.0mm) and baseplates rated for cumulative multi-tier loads during the initial project design. HEDA's modular upright column punchings permit the seamless post-installation addition of intermediate catwalk beams, cold-rolled interlocking steel floor planks, staircase towers, and perimeter safety handrails without on-site cutting or hot welding.
Containerized long-distance freight demands specialized protection. Our upright columns and beams are banded in structural timber dunnage with high-density corrugated wrap and PE protective stretch film. Separating corner protectors shield powder-coated edges from friction wear, while small accessories (baseplates, safety drop pins, shims, and fasteners) are packaged in reinforced export wooden crates or double-walled corrugated cartons with desiccants to prevent sea-humidity rust.
With our 30,000 metric-ton monthly capacity, standard customized orders of 1 to 3 full 40-foot high-cube containers (40HQ) are fabricated, powder-coated, inspected, and packaged within 15 to 20 working days following CAD drawing sign-off. High-volume turnkey installations exceeding 1,000 pallet positions are phased according to site handover milestones, ensuring just-in-time delivery synchronized with your facility's construction timeline.
