China Best Picking Racking Manufacturers & Exporter

We exclusively manufacture using prime high-tensile Q235B cold-rolled structural steel (equivalent to European S235JR and American ASTM A36) sourced directly from certified state-owned steel mills. This ensures a uniform yield strength of 235 MPa and superior weldability. Our structural calculations comply with European Federation of Materials Handling (FEM 10.2.02) and Rack Manufacturers Institute (RMI) standards, maintaining an ultimate safety factor of 1.5 to 1.8 across all static and seismic load conditions.

Protection begins with an automated 7-step chemical immersion sequence that removes scale and deposits a micro-crystalline iron phosphate barrier. Components then receive thermosetting electrostatic epoxy-polyester powder coating cured at 200°C, producing a resilient 60–80 micron film. For outdoor applications, cold-storage environments, or coastal facilities (such as Mombasa, Tema, or Lagos), we offer hot-dip galvanization with a minimum 85-micron zinc layer for over 25 years of corrosion resistance.

Yes. When you provide your architectural blueprints and soil/slab data, our structural engineers evaluate point load concentrations at column baseplates. We configure enlarged baseplates, heavy anchor bolts, top ties, and back portal bracing to distribute loads evenly. For seismic zones, we incorporate finite element analysis (FEA) to confirm sway deflection limits under regional seismic acceleration coefficients.

To prepare a production-grade CAD layout, 3D rendering, and bill of materials, please provide:
1. Architectural clear ceiling height, pillar spacing, floor flatness, and overhead obstruction heights (HVAC, fire sprinklers).
2. Unit load data: Pallet or carton dimensions (Width × Depth × Height) and maximum loaded weight.
3. Material handling equipment: Forklift brand, mast reach height, aisle turning radius, and lift capacity.
4. Stock rotation criteria: Number of active SKUs, daily throughput volume, and FIFO vs. LIFO preference.

All upright frames and beams are nested into banded, timber-cushioned steel crates to prevent metal-on-metal friction. Uprights are protected with corrugated cardboard and multi-layer stretch film, while beam connectors feature corner guard caps. Small hardware, bolts, and safety lock pins are packed in weather-sealed wooden cases. Loading plans are modeled via 3D software to optimize 20GP/40HQ container space, eliminate transit shifting, and simplify offloading.

Yes. Our boltless beam-to-frame connector locks make installation straightforward without specialized site welding. Every order includes stamped CAD assembly drawings, step-by-step manuals, and video tutorials. Every package is numbered to match the installation plan. For large-scale multi-tier mezzanines or automated installations, we can dispatch senior site supervisors to oversee the local crew.

Standard picking and selective pallet racking systems ship within 14 to 21 working days after drawing sign-off. High-volume multi-tier mezzanine contracts typically require 25 to 30 days. We operate under all standard Incoterms, including FOB (Guangzhou, Shenzhen, Foshan), CFR, CIF (to major ports worldwide), and DDP upon request.

All structural steel uprights and beams carry a 5-year structural warranty against manufacturing and welding defects under normal rated loading. We also supply additional safety beam locks, upright column protectors, and touch-up coatings with every container. If future expansion requires reconfiguring beam levels or adding aisles, our engineering files ensure 100% component compatibility.
