Manufactured with high-tensile Q235B and Q355B structural steel, our factory-direct racking solutions meet rigorous FEM 10.2.02, RMI MH16.1, and AS4084 structural engineering standards. Explore our 8 primary export configurations below.
Backed by over two decades of heavy industrial manufacturing, Guangzhou Heda Shelves Co., Ltd. controls the complete vertical supply chain from raw hot-rolled strip slitting to automated continuous roll-forming and robotic welding.
Fully certified under European CE Standard (Certificate 2435-CPR-8605159) and ISO 9001:2015 Quality Management Systems (Certificate 18624Q00169R0M). All structural load computations are verified against cold-formed steel design standards.
Unlike small fabricators that rely on simple solvent wiping, our steel undergoes automated high-temperature alkaline degreasing, multi-stage acid pickling, rust removal, phosphating, and deionized water rinsing before electrostatic epoxy powder coating.
Our in-house project engineering division delivers complete AutoCAD layout schemes, 3D parametric warehouse renderings, forklift aisle clearance models, and anchor bolt shear/pullout calculations within 24 business hours of floor plan receipt.
Export packing is engineered specifically for 40ft High Cube sea containers. Uprights and beams are systematically bundled with heavy-duty steel strappings and corner edge protectors to achieve maximum ocean freight space utilization.
Selecting industrial pallet racking requires deep comprehension of thin-walled cold-formed steel behavior, perforated column axial buckling, and beam-to-column connector moment resistance.
Storage racks are structurally optimized cold-formed steel structures subject to both static gravity dead loads (the weight of the steel and stored pallets) and dynamic transient live loads (forklift impact, seismic lateral acceleration, pallet placement vibration). We specify primary structural members based on standardized chemical and mechanical parameters:
Q235B Cold-Rolled Carbon Steel: Yield strength $f_y \ge 235 \text{ MPa}$, ultimate tensile strength $f_u = 370\text{--}500 \text{ MPa}$, elongation $\delta_5 \ge 26\%$. This alloy provides exceptional cold-bending plasticity, making it the premier choice for roll-formed upright columns with intricate 50mm/75mm multi-bend profiles and step/box beam connector brackets.
Q355B Low-Alloy High-Strength Steel: Yield strength $f_y \ge 355 \text{ MPa}$, ultimate tensile strength $f_u = 470\text{--}630 \text{ MPa}$. Applied across heavy cantilever arms, drive-in support brackets, high-bay automated storage retrieval systems (AS/RS), and high seismic zones where maximum axial load carrying capacity per kilogram of steel is required.
Under rated operational loads, beam deflection directly affects forklift mast positioning, automated sensor scanning, and overall rack stability. According to international standards, the vertical elastic deflection of horizontal rack beams under uniformly distributed pallet load must not exceed:
$\delta_{max} \le \frac{L}{200}$ (where $L$ is the clear span distance between upright columns)
For automated shuttle tracks and high-tolerance AS/RS integrations, HEDA Shelves tightens this threshold to $\delta_{max} \le L/300$. Furthermore, our interlocking beam end connectors feature 3-claw or 4-claw precision stamped engagement teeth welded seamlessly to the beam with robotic CO₂ gas-shielded arc welding. This generates a rigid semi-rigid joint with calculated rotational stiffness ($C_d$) that drastically diminishes overall unbraced frame length and lateral drift during seismic excitations.

Warehousing infrastructure is shifting rapidly toward automated compaction, carbon accountability, and dynamic seismic survivability. Supply chain directors must evaluate these architectural procurement trends.
Escalating industrial land costs and severe labor shortages in major logistics corridors are accelerating the transition from traditional 3.5m wide-aisle selective racking to dense semi-automated radio shuttle systems and vertical AS/RS rack clad structures. Warehouse managers are demanding modular racking profiles that allow future retrofitting of lithium-powered shuttle bots without tearing down existing upright frameworks.
With the rapid expansion of cross-border pharmaceutical and frozen food cold chains across humid equatorial zones (such as South Asia, Southeast Asia, and the Middle East), standard interior powder coatings are proving insufficient. Procurement specifications increasingly require hot-dip galvanized uprights (ASTM A123 / ISO 1461) or specialized zinc-rich epoxy primers tested to withstand 1,000+ hours of continuous neutral salt spray (ASTM B117).
Regulatory building bodies worldwide are tightening enforcement of structural rack safety under dynamic seismic loading. Modern procurement contracts now mandate finite element analysis (FEA) validating baseplate bolt shear, floor slab punching shear capacity, and frame ductility factors under specific spectral acceleration zones (Ss and S1 ratings), ensuring racks withstand earth tremors without progressive catastrophic collapse.
