OEM/ODM Heavy Duty Shelving Manufacturers & Factory

We purchase cold-rolled and hot-rolled coils directly from prime tier-1 steel mills. Each batch is accompanied by an authentic Mill Test Certificate (MTC) conforming to EN 10204 Type 3.1. Our in-house metallurgical laboratory performs destructive yield strength testing ($R_e \ge 235 \text{ or } 355 \text{ MPa}$), ultimate tensile testing ($R_m$), and elongation verification before feeding slit coils into automated roll-forming lines.

According to FEM 10.2.02 and RMI standards, vertical beam deflection under Safe Working Load (SWL) must not exceed $L/200$ (for manual picking shelving) and $L/250$ to $L/300$ (for pallet racking and automated shuttle lanes), where $L$ represents span length. Our engineers calculate safety coefficients with a structural margin of 1.5 to 1.67 over elastic yield failure limits.

Yes. As a full-scope OEM/ODM factory, our tooling center creates dedicated high-speed punching dies. We regularly produce American standard teardrop slots (50.8mm pitch), European 50mm and 75mm slotted patterns, 76.2mm Commonwealth styles, and proprietary hook configurations to match existing warehouse legacy racking systems seamlessly.

We utilize an automated 9-stage pre-treatment cycle (alkaline degrease, double clean rinse, nano-ceramic conversion layer, demineralized mist) followed by electrostatic application of thermosetting polyester or epoxy-polyester powder (60–90 µm thickness). It passes ASTM B117 salt spray tests exceeding 500 hours (up to 1,000 hours with zinc-rich epoxy primer for offshore or coastal applications).

To provide precise CAD proposals and structural bills of materials (BOM), please supply: 1) Architectural floor plan indicating column spacing, dock doors, and obstruction heights; 2) Pallet dimensions ($W \times D \times H$) including product overhang; 3) Maximum gross pallet weight; 4) Warehouse clear ceiling height and sprinkler drops; 5) Operating forklift brand, turning radius, and maximum reach height.

All upright frames and beams are nested with high-density corrugated spacers, shrink-wrapped in micro-perforated protective film, banded with heavy polyester strapping, and supported on heavy steel skids. Beam ends and connector claws are covered with reinforced composite corner protectors to prevent impact shearing during multimodal intermodal transit.
