OEM/ODM Cantilever Rack Storage Manufacturers & Manufacturer

Cantilever load capacity is not a simple cumulative sum. Arm capacity is calculated on a Uniformly Distributed Load (UDL) assumption across the usable arm length. If the load is concentrated at the arm tip, maximum bending stress doubles, reducing effective capacity by up to 50%. Column load capacity depends on overall height, vertical arm spacing, and single vs. double-sided symmetry. Double-sided columns counteract opposite bending moments when loaded equally, whereas single-sided columns require heavier flange thicknesses to resist continuous eccentric overturning forces.

Yes. In high seismic zones across the Philippines, Indonesia, Japan, and Taiwan, our technical department conducts finite element modal analysis (FEM). We calibrate base plate dimensions, add gusset stiffener plates, specify high-ductility anchor bolts with embedment depths up to 250mm, and introduce continuous heavy diagonal back-bracing systems. Complete structural engineering calculation reports and PE stamps can be supplied for local government building permit applications.

All components pass through an automated 10-stage pre-treatment line: degreasing, water rinsing, acid pickling to eliminate mill scale, secondary rinse, and zinc phosphating to establish an active micro-crystalline anti-corrosion barrier. Following pre-treatment, components enter an electrostatic powder booth where lead-free, RoHS-compliant thermosetting polyester resin is applied at 60 to 80 microns thickness, cured in a 200°C baking tunnel. For extreme coastal or outdoor operations, full hot-dip galvanization conforming to ASTM A123/ISO 1461 is available.

For light roll-formed systems (arm loads ≤ 500 kg), a reinforced slab of 150mm thickness with 25 MPa compressive strength is generally sufficient. For heavy-duty structural I-beam systems (arm loads 1,000 kg to 5,000 kg and column heights ≥ 6,000 mm), concrete thickness must reach 200mm to 300mm with 30 MPa minimum strength, free of expansion joints within 200mm of anchor bolt holes. If the existing foundation does not meet these criteria, our engineers design load-distributing spreader base beams to safely reduce localized soil stress.

Freight cost optimization forms a core component of our export engineering. Cantilever columns, bases, and arms present irregular geometry. We engineer custom nested steel racking cradles that lock profiles tightly, preventing transit friction while allowing fast unloading by forklift. Uprights and arms are bundled using protective non-marking bubble wrap and heavy polyester strapping. A standard 40ft High Cube container typically holds between 22 to 26 metric tons of steelwork, keeping shipping freight cost per pallet position to a minimum.

To generate an accurate engineering drawing and budget breakdown, send us: (1) Warehouse architectural CAD or dimensioned sketch noting clear building height and internal obstacles; (2) Detailed product dimensions (outer diameter, length, minimum/maximum weight per bundle); (3) Forklift model, mast maximum lift height, and minimum turning radius; and (4) Site installation location to verify seismic and wind code parameters. Our bilingual engineering team will provide a 3D visual rendering, column load verification, and itemized factory-direct quote within 24 to 48 hours.
