Top Trusted Heavy Duty Racking Systems Supplier & Exporter

Under international standards (such as EN 15512 and RMI MH16.1), the maximum permissible deflection under maximum uniformly distributed load (UDL) is calculated as L/200, where L is the clear span of the horizontal beam. For example, a 2,700mm beam rated at 3,000kg will not deflect more than 13.5mm at its center point. HEDA Shelves validates all beam sections via physical hydraulic test beds and FEA software before mass manufacturing.

We utilize certified primary structural steel coils sourced directly from top mills (Baosteel, Shougang). Upright columns are rolled from high-yield Q355B (equivalent to ASTM A572 Grade 50 / EN 10025 S355JR), featuring a minimum yield strength of 355 MPa. Beams are cold-formed from Q235B or Q355B depending on deflection parameters. Full Mill Test Certificates (MTC 3.1) accompany each export batch.

For projects in seismically active regions (e.g., Chile, Peru, California, Japan), our engineers apply the local design response spectra (such as NCh 2369 or ASCE 7). We thicken the footplate weldments, upgrade chemical shear anchor specifications (M12 to M16 Hilti/Fischer anchors), incorporate diagonal cross-bracing in the rear plane, and add top spine ties to eliminate systemic structural twisting during ground acceleration.

For standard interior warehouses, our automated electrostatic line applies 60–80 microns of epoxy-polyester thermoset powder cured at 200°C. For deep-freeze warehouses operating at -25°C to -30°C where moisture condensation is persistent, or open-air marine ports, we provide hot-dip galvanized steel components conforming to ASTM A123 / ISO 1461, guaranteeing lifetime corrosion resistance.

Selective Racking represents the lowest initial capital cost ($25–$45 per pallet position) but utilizes only 40% of the warehouse volume due to wide aisle requirements (3.0m–3.5m). Radio Shuttle racking requires a higher upfront cost ($90–$160 per position, including automated cart units), but achieves over 80% volume density, slashing refrigerated power consumption and building lease expenditure.

With a dedicated monthly fabrication volume exceeding 30,000 metric tons, standard 40HQ full-container orders (FCL) of selective or drive-in racking are fabricated within 14 to 25 calendar days after CAD shop drawing approval. Large-scale distribution center projects exceeding 50 containers are dispatched in scheduled rolling batches to match civil engineering construction milestones.

Heavy upright frames and beams are bundled with dedicated protective cardboard corner wraps, multi-layer stretch shrink film, and heavy-duty polyester strapping. Components are loaded into 40ft High Cube (40HQ) containers utilizing specialized mechanical dollies to optimize both total gross payload (up to 26–28 metric tons) and container cubic volume while preventing transit abrasion.

Multi-tier mezzanine platforms generate concentrated point loads through baseplates that must not exceed the concrete slab's punch-shear resistance (typically 200–250mm reinforced concrete with 25–30 MPa compressive strength). HEDA Shelves provides customized oversized baseplates (e.g., 300x300x12mm or larger) to redistribute localized point stresses safely across your existing slab without cracking.

Forklift operators occasionally catch pallet corners on the underside of beams while lifting. Each beam-to-column connection in our systems features spring-action or gravity-drop galvanized steel safety lock pins that withstand an upward shear force of over 5.0 kN. This mechanically locks the claw connector into the column slot, preventing accidental vertical disengagement.

We provide complete project submittal packages including 2D architectural CAD layouts, 3D structural perspective renderings, bill of materials (BOM), load distribution calculation certificates, Mill Test Reports (MTC 3.1), CE Declaration of Conformity, and structural assembly guidelines. These enable your local civil engineer to endorse municipal building permits swiftly.
