Custom OEM Warehouse Racking Factories & Wholesaler Hub

Our OEM production follows the Rack Manufacturers Institute (RMI) Specification for the Design, Testing, and Utilization of Industrial Steel Storage Racks (ANSI MH16.1). Welded structural components conform to AWS D1.1 and the Canadian Welding Bureau (CWB) CSA Standard W47.1 Division 3. For European project installations, EN 15512 and FEM 10.2.02 structural verification parameters are strictly integrated into production testing.

Under the International Building Code (IBC) and ASCE 7 provisions, the Seismic Design Category (SDC A through F) directly influences the size, thickness, and anchorage of column base plates. High seismic zones (such as California, the Pacific Northwest, or British Columbia) necessitate enlarged base plates, heavy structural anchors with increased concrete embedment, heavier horizontal/diagonal frame bracing, and occasionally kinetic base isolation systems to withstand lateral acceleration forces.

For custom upright punch spacing (e.g., proprietary imperial or metric pitches) or bespoke RAL powder-coating colors, our standard OEM minimum production run begins at one 40-foot high-cube container (approx. 18-22 metric tons of steel). Standard inventory profiles—such as 76.2mm teardrop columns and standard step beams in safety green and orange—are stocked with immediate availability for quick-ship orders.

Roll-formed teardrop rack is cold-rolled from high-tensile sheet steel, offering lower dead-weight, fast tool-less assembly via pin locks, and cost-effective selective pallet storage. Hot-rolled structural C-channel rack uses heavy steel sections joined with structural bolts, providing exceptional impact resistance in high-cycle forklift aisles, blast freezers, and harsh distribution environments where forklift upright impacts are common.

Operating temperatures below 0°C (and especially down to -30°C in blast freezers) make standard low-grade carbon steels susceptible to brittle fracture. We utilize specialized fine-grained micro-alloyed steel grades with certified Charpy V-notch toughness. Surface finishes typically utilize high-build hot-dip galvanizing (HDG) per ASTM A123 or multi-stage specialized epoxy powder coatings formulated to resist thermal contraction micro-cracking.

Yes. For major distribution centers, retail racking systems, and mezzanine installations across all 50 U.S. states and Canadian provinces, we provide comprehensive structural engineering calculation packets stamped by a registered Professional Engineer (PE or SE). These packets evaluate soil site class, building slab capacity, anchor pullout loads, and seismic response spectra.

Custom OEM manufacturing schedules generally range from 3 to 5 weeks from approved shop drawings to container stuffing, depending on project scale and surface treatment requirements. Standard ocean transit times to West Coast North American ports average 14–20 days, and East Coast ports 28–35 days. Fast-track delivery is facilitated via our North American quick-ship distributor network.

Upright frames and horizontal beams are bundled using heavy-duty steel strapping, high-density corrugated edge protectors, timber dunnage blocks, and waterproof shrink wrap. Specialized nesting brackets are employed inside 40HC containers to prevent inter-metal contact abrasion, ensuring the factory-applied powder coat finish arrives without scratches or rust blemishes.
