China Best Lightweight Pallet Racking Factories & Exporter

We primarily utilize prime cold-rolled commercial structural coil conforming to GB/T Q235B and Q355, which correlate directly with North American ASTM A1011 SS Grade 36 and European EN 10025 S235JR / S355JR. Mill test certificates (MTC) exhibiting certified chemical composition (Carbon, Manganese, Silicon, Phosphorus) and physical properties (yield strength $\ge 235$ MPa, tensile strength 370–500 MPa, and elongation $\ge 26\%$) are supplied with every shipping batch.

Our standard beam levels for North American operations are engineered to 96" or 108" clear spans to comfortably hold two standard 48" x 40" GMA pallets with the requisite 3" side clearance and 4" center flue space. Upright frame depths are systematically set at 42" to ensure a 3" pallet overhang front and rear, maximizing pallet bottom runner seating directly across both load beams without risking displacement.

Yes. Guangzhou Heda Shelves supplies comprehensive engineering packages comprising component section modulus data, dead-and-live load capacity calculations, beam deflection curves, and base plate anchor shear models. These engineering submittals are prepared specifically to assist your domestic state-licensed Engineer of Record (EOR) who provides local municipal seismic stamps.

All fabricated components undergo a rigorous chemical pre-treatment cycle consisting of hot alkaline degreasing, acid pickling, iron phosphating, and deionized water rinsing before finishing. They are subsequently coated with high-grade electrostatic polyester powder (60–80 micron film thickness) cured at 190°C. For sub-zero freezers or open humid staging docks, hot-dip galvanizing per ASTM A123 is available.

Under both RMI MH16.1 specifications and FEM 10.2.02 codes, the maximum allowable vertical deflection for horizontal pallet load beams under uniformly distributed loads (UDL) must not exceed $L/200$, where $L$ is the clear span distance between columns (e.g., maximum deflection of 0.48 inches on a 96-inch beam). Our lightweight beam profiles are sized to operate safely within this threshold with a safety factor of 1.65 to 1.9.

Upright frames and beams are nested on heavy-duty timber skids with high-tensile steel strapping, corner edge protectors, and multiple wraps of moisture-barrier stretch film. Beam connectors are cushioned with corrugated spacers to prevent tab deformation. Loose small components (locking pins, footplates, shims, hardware) are crated in labeled seaworthy plywood cases.

Absolutely. Our step beams feature an internal 7/8" or 1-1/8" step recess designed to seat standard flared or step-style welded wire mesh decks flush with the top beam face. Drop-in top-hat cross supports, pallet support bars, and front-to-back safety ties are easily configured depending on whether you handle timber skids, plastic pallets, or steel bins.

For standard custom-dimension orders of 1 to 5 forty-foot high-cube (40HQ) containers, our manufacturing turnaround is typically 15 to 20 working days following approved CAD shop drawings. Full layout reviews, itemized quotations, and 3D CAD models are returned within 24 hours of receiving initial warehouse boundary plans.
