OEM/ODM Narrow Aisle Racking System Manufacturer & Supplier

Narrow aisle racking systems with turret trucks lifting over 10 meters demand superflat concrete slabs conforming to DIN 18202 (Table 3, Line 4) or British Standard Concrete Society TR34 (Class DM2 or FM2). Because mast deflection magnifies ground surface tilt exponentially at an 18-meter apex, excessive transverse or longitudinal waviness can cause truck impact with structural uprights. HEDA Shelves engineers review your floor topographic survey and supply leveled shims, heavy anchor base plates, and portal top-ties to guarantee structural integrity.

For earthquake-prone areas such as Japan, the Philippines, Indonesia, and Taiwan, standard static load calculations are insufficient. Our engineering department runs dynamic finite element analysis (FEA) compliant with Eurocode 8 and local seismic codes. We optimize steel wall thickness, utilize Q355B high-tensile upright profiles, incorporate reinforced diagonal and horizontal K-bracing patterns, integrate seismic dampening base plates, and embed multi-anchor expansion bolting to ensure horizontal ground accelerations (up to 0.4g–0.6g) are fully dissipated without catastrophic failure.

Both mechanisms are fully supported in HEDA OEM designs. Mechanical guide rails typically utilize continuous structural angle steel (e.g., L100x75x8mm or L125x75x10mm) anchored directly along the bottom column perimeter with heavy entrance lead-in horns. Guide rails physically protect bottom pallet loads from truck steering errors. Wire guidance involves cutting a shallow channel down the center of the aisle to embed an inductive low-frequency antenna wire. While wire guidance allows cleaner floor access and faster pallet staging at aisle ends, mechanical guide rails provide a permanent physical barrier favored in high-throughput distribution depots.

Corrosion protection begins with chemical surface preparation. At HEDA Shelves, components undergo an automated chemical submersion cycle including degreasing, acid pickling to eliminate scale, water rinsing, and zinc phosphating. This chemically bonds a protective conversion coating prior to electrostatic polyester powder coating (baked at 180°C–200°C), resulting in a scratch-resistant 70µm–90µm dry film thickness. For extreme applications such as sub-zero cold rooms (-30°C), exterior yards, or coastal distribution points, we supply hot-dip galvanized steel components conforming to ISO 1461 with 85µm+ zinc coating depth.

To generate an accurate 2D CAD layout, 3D visualization, and load calculation report within 24 to 48 hours, our technical team requires: (1) Warehouse building DWG or dimensional sketch showing clear height under sprinklers/beams, column grid spacing, and door positions; (2) Pallet dimensions (Length x Width x Height including cargo overhang) and gross pallet weight; (3) Turret truck or forklift model, turning radius, and maximum lift height; (4) Total SKU profile, throughput rates, and temperature requirements.

Yes. As a direct OEM/ODM manufacturer, we fabricate custom tooling and roll-forming dies for regional distributors and systems integrators across Europe, North America, and Australia. We can produce custom teardrop patterns, proprietary keyhole uprights, specific beam connector lug geometries, customized color matching (RAL standard powder formulas), and custom private-label laser marking or bundle tag packaging.
