Custom OEM Narrow Aisle Racking Manufacturer & Exporters

Narrow aisle racking systems operating with man-up turret trucks up to 18 meters require strict adherence to international concrete flatness standards, such as Concrete Society TR34 (Class DM1 or DM2 for Defined Movement) or DIN 18202 Table 3 Line 3. Because mast oscillation at high elevations amplifies minute slab bumps, failure to achieve these tolerances will cause turret trucks to slow down or strike rack frames. Our design team reviews your slab surveys prior to manufacturing baseplate sizing.

All upright frames are manufactured in knock-down (KD) bolted assemblies rather than fully welded trusses. The upright posts, horizontal/diagonal bracing channels, and baseplates are flat-packed in high-density bundles strapped with steel banding and protective corner edge boards. Box beams are nested together. This methodology maximizes both container cubic space and payload weight limits, allowing up to 24–26 metric tons to fit inside standard 40ft High Cube containers.

Mechanical guidance uses heavy structural steel angles (typically 100 x 75 x 8 mm or 120 x 80 x 10 mm) bolted securely into the slab down both sides of the narrow aisle. Rollers on the bottom of the VNA truck run against these angles. Inductive wire guidance involves cutting a thin slot into the concrete down the center of the aisle and inserting a low-frequency energized antenna wire. Mechanical rails offer physical chassis protection and lower upfront cost, whereas wire guidance facilitates easier aisle cleaning and quicker truck ingress.

Yes. As an OEM/ODM manufacturer with dedicated CNC-controlled tooling lines, we can custom-punch upright post profiles to match existing diamond, teardrop, keyhole, or custom European/American pitch configurations (such as 50mm, 75mm, 76.2mm / 3-inch pitches). We provide structural verification to confirm beam claw interlock compatibility and moment-resisting connection capacity.

We exclusively procure prime structural steel coils certified to Q235B, Q355B (equivalent to St52-3 / S355JR), and high-strength cold-rolled coil. Each export production lot is accompanied by certified Mill Test Certificates (EN 10204 Type 3.1) detailing chemical composition (carbon, manganese, phosphorus, sulfur) and mechanical properties including yield strength, ultimate tensile strength, and elongation percentage.

Our structural engineering department performs finite element modeling conforming to EN 15512 (Steel Static Storage Systems – Adjustable Pallet Racking Systems – Principles for Structural Design), FEM 10.2.02, and ANSI / RMI MH16.1. For projects in seismic zones (such as western India, Canada, and seismic pockets of the Middle East), we incorporate enlarged ductile baseplates, double anchor bolts, and heavy-duty frame bracings designed to resist prescribed ground acceleration factors.

For cold stores, pharmaceutical cleanrooms, or coastal climates, we offer pre-galvanized high-yield steel coils, hot-dip galvanization conforming to ISO 1461 (providing zinc coatings up to 60–85µm for decade-long anti-corrosion), or our multi-stage thermosetting epoxy-polyester architectural powder coating with specialized zinc-rich primer coats.

To generate a complete structural design, layout drawing, and bill of quantities, our engineers require: (1) Warehouse architectural CAD layout including clear ceiling heights and column grids, (2) Pallet dimensions (W x D x H) including load overhang, (3) Maximum gross pallet payload weight, (4) Specific MHE or VNA truck make/model for minimum aisle width and lift clearances, and (5) Floor slab thickness and seismic zone data.
