China Wholesale Storage Racking Factories & Factory

To prepare safe, cost-efficient CAD layouts and static engineering calculations, our engineering department requires: (1) Warehouse architectural drawings indicating clear ceiling height, column matrix, entry doors, floor joints, and overhead fire-sprinkler drops; (2) Concrete floor slab data including thickness and compressive strength (typically 20-30 MPa); (3) Unit load specifications: pallet width, depth, height, and maximum gross load including overhang; (4) Forklift specifications: model, mast collapsed and extended heights, turning radius, and minimum aisle width; and (5) Local seismic zone parameters per building code.

HEDA racking components are engineered in compliance with EN 15512 (European standard for steel static storage systems) and RMI guidelines. The maximum allowable beam vertical deflection is governed by a strict L/200 limit (where L represents clear span between uprights), ensuring beams do not exceed elastic yield limits under uniform distributed loads (UDL). Upright frames undergo buckling capacity verification using second-order structural analysis with a minimum safety factor of 1.5 to 1.67 over nominal design loads.

For standard indoor ambient distribution warehouses, components receive a 9-stage chemical wash, pickling, iron phosphating, and automated electrostatic powder coating (60-80 microns thickness) with thermosetting polyester resin. For extreme tropical environments with high ambient relative humidity (>80%), coastal port locations, or refrigerated/freezer rooms (-30°C) where condensation cycles accelerate steel oxidation, we provide heavy-duty continuous hot-dip galvanizing according to ISO 1461, delivering an anti-corrosion barrier with an expected service life exceeding 20 years.

Storage racking is heavy and volumetric. We employ specialized 3D packing simulation software to calculate container nesting for 20GP, 40GP, and 40HQ configurations, avoiding both dead air space and container overweight penalties. Uprights are bundled by frame depth, beams are steel-banded with protective wood dunnage, and small accessories are packed in reinforced, palletized wooden crates. Shipments are quoted on Incoterms (FOB, CIF, CFR, DDU) with complete packing lists, mill test certificates (MTCs), Bills of Lading, Certificates of Origin, and CE conformity documentation.

Every shipment includes a detailed installation manual, assembly schematics, fastener schedules, and anchor bolt torque specifications. Every upright frame, beam, and brace bundle is clearly labeled corresponding to the CAD project layout. For enterprise facilities, our project engineering division provides step-by-step remote video assembly guidance, or deploys seasoned installation field engineers directly to the client site to supervise local mechanical crews, calibrate laser leveling across the slab, and certify final sign-off testing.
