Explore heavy-duty teardrop, slotted channel, and beam-locking systems manufactured from certified cold-rolled structural steel (Q235B/Q355B). Designed for maximum live-load integrity across automated fulfillment hubs, high-bay distribution centers, and extreme ambient industrial facilities.
Our senior structural engineering team prepares comprehensive seismic analyses, upright punched profiles, and bay calculations according to FEM 10.2.02, EN 15512, and RMI standards within 24 hours.
Established in 2001, Guangzhou Heda Shelves Co., Ltd. operates a premier 30,000 m² heavy-machinery production complex. Supplying high-tolerance slotted pallet racking systems, structural mezzanines, and dynamic automated logistics equipment across the Middle East (UAE, KSA, Qatar, Kuwait, Oman, Bahrain), Europe, the Americas, and Southeast Asia.
Upright columns are manufactured using continuous CNC roll-forming lines with multi-point cold bending, delivering omega (Ω) structural profiles with integrated 50mm, 75mm, or 76.2mm teardrop pitch punchings.
Engineered for extreme GCC ambient environments (hot coastal air, high salinity, fine quartz dust) and refrigerated cold stores down to -30°C through an advanced multi-stage automated pretreatment line.
Comprehensive front-end engineering design (FEED). We produce CAD floor plans, 3D BIM models, and aisle safety clearances meeting local fire, civil defense, and industrial municipal codes.
Quality control is executed at every milestone under strict ISO 9001:2015 protocol, preventing batch discrepancies and assuring 100% mechanical consistency upon arrival at global project sites.










A slotted pallet rack relies on cold-formed slotted upright frames connected with interlocking box beams or step beams. In global procurement, specifying the correct slotted pattern, steel thickness, and connection locking pin is critical for warehouse safety and seismic resistance.

When evaluating structural proposals, procurement directors must inspect the effective moment of inertia (Ix, Iy) of the slotted upright. Slotted perforations inevitably remove steel material; HEDA Shelves utilizes proprietary cold-forming dies that punch the slotted apertures first, followed by continuous precision progressive folding. This process induces cold-work hardening around the slot borders, compensating for the voided surface and yielding structural safety factors exceeding 1.65 under design working loads.
The rapid scaling of modern intralogistics, supply chain regionalization, and automation drives radical updates in slotted pallet rack specifications.
Traditional static slotted racks are increasingly procured as hybrid structures ready for automation. Uprights are pre-punched with high-precision reference holes to anchor 4-way radio shuttle guide rails, vertical tote lifts, and stacker crane tie-ins without field welding.
Enterprise buyers require full IFC and Autodesk Revit BIM models from manufacturers before placing purchase orders. Every slotted component is parametrically rendered to interface with warehouse management software (WMS) and automated fire sprinkler clash detection.
Driven by ESG and cross-border carbon border adjustment mechanisms (CBAM), procurement managers are favoring manufacturers who use low-carbon EAF steel coils and eco-friendly zirconium/silane pretreatment that eliminates toxic heavy metals.
Procuring from China requires undeniable proof of metallurgical compliance, weld integrity, and dimensional consistency. HEDA Shelves components are backed by fully traceable serial-numbered certification documents for project engineering audits.
Key technical, financial, and logistical insights for general contractors, supply chain directors, and logistics facility managers importing slotted racking from China.
Teardrop slotted racking follows the dominant North American standard featuring a 2-inch (50.8mm) increment pitch and inverted teardrop holes that accept gravity-locking pin studs. The 75mm diamond/hexagonal pattern is the standard European/Australian profile (EN 15512 / AS 4084), utilizing multi-tooth stamped connector clips with heavy spring-steel lock pins. HEDA Shelves engineers both configurations with continuous automated punch dies.
Racking components face maritime salinity and high dynamic friction inside sea containers. We bundle upright frames and beams with protective corrugated corner guards, heavy-gauge plastic stretch wrap, and wooden skid blocks. Metal-to-metal strapping is separated by polyester buffer pads to protect the powder-coated layer. Bundles are labelled with QR-coded part numbers matching container loading manifests.
Yes. In high-density logistics facilities, regulatory compliance requires precise longitudinal flue spaces (typically 75mm–150mm between back-to-back rows) and transverse flue openings between pallets. Our engineering team designs row spacers, pallet backstops, and wire mesh decking that ensure unimpeded downward water penetration for Early Suppression Fast Response (ESFR) ceiling heads.
Standard production for standard slotted pallet racks (2 to 5 containers, 40ft HQ) is 15 to 22 business days from drawing approval and raw steel metallurgical verification. For custom RAL color coatings or hot-dip galvanized specifications, lead time ranges between 25 and 30 business days. Priority expedited roll-forming schedules can be arranged for fast-track project milestones.
