Custom OEM Carton Flow Racking Manufacturer & Factory

To generate an accurate CAD layout and load calculation, our engineers require: (1) Dimensions of carton boxes or plastic containers (Length × Width × Height), (2) Minimum and maximum deadweight per loaded container, (3) Carton base material (corrugated paper, rigid plastic, or composite base - this determines roller friction coefficient), (4) Desired number of levels per bay and overall warehouse clear building height, (5) Inventory SKU count and rotation frequency (FIFO vs. LIFO), and (6) Required aisle widths for replenishment and order picking carts.

The optimal angle typically ranges between 2.5° and 4.5° (roughly 40mm to 70mm drop per linear meter of track). Lighter containers or corrugated cardboard boxes with flexible bases create higher rolling resistance and necessitate a steeper gradient (~4.0° to 4.5°). Heavier rigid plastic totes roll with significantly less friction and achieve ideal forward travel at 2.5° to 3.0°. In our OEM design, upright frames feature 50mm or 25mm micro-pitch adjustment slots, enabling on-site technicians to fine-tune the velocity during initial load testing.

Yes. One of HEDA's primary OEM competencies is producing universal drop-in carton flow shelves and hanger brackets engineered to clamp seamlessly onto standard teardrop, slotted, or box beams from third-party manufacturers. This allows fulfillment facilities to transform their bottom two pallet racking tiers into high-velocity piece-picking lanes while maintaining upper levels for bulk palletized reserve storage, saving thousands in capital facility investment.

Every structural steel component undergoes a rigorous 10-step industrial finishing process at our Guangzhou facility. This begins with acidic pickling to eliminate mill scale and rust, followed by zinc phosphate immersion for molecular bonding. Components then pass through an automated electrostatic powder-coating booth, receiving a thermoset polyester finish cured at 180°C–200°C with an average film thickness of 60–80 microns. For harsh, marine coastal depots or cold rooms, hot-dip galvanizing and pre-galvanized roller track housings are supplied.

Standard OEM production cycles span 15 to 25 business days depending on custom tooling, stamping geometries, and total steel tonnage. Because we are a primary steel manufacturer with an output of 30,000 tons per month, we accommodate both specialized batch trial orders (MOQ starting at 10 bay sets or 1 full 20GP container equivalent) up to multi-thousand-bay distribution center build-outs with continuous containerized rolling shipments.
