Top China Rack Shelving System Manufacturer & Suppliers

As an engineering-driven manufacturer based in Guangzhou, China, Guangzhou Heda Shelves Co., Ltd. approaches industrial storage design through the lens of finite element analysis (FEA) and international design codes. The performance of industrial pallet racks begins at the atomic structure of the primary coil. We strictly source prime cold-rolled steel coils conforming to standard GB/T 700 Q235B (Yield Strength $f_y \ge 235 \text{ MPa}$, Tensile Strength $370\text{--}500 \text{ MPa}$) and high-strength low-alloy structural steel GB/T 1591 Q355B (Yield Strength $f_y \ge 355 \text{ MPa}$, equivalent to ASTM A572 Grade 50 or European S355JR). Utilizing Q355B high-grade steel allows up to a 15–22% optimization in profile deadweight while elevating load-bearing thresholds and post-elastic energy dissipation during seismic excitation.

Modern cold roll-forming lines feature multi-station progressive rollers that eliminate residual micro-stresses within upright corners. The geometric profile of our Omega ($\Omega$) upright sections features continuous stiffening ribs along the flange and web, engineered specifically to resist torsional-flexural buckling under axial compression. Upright hole punching (50mm, 75mm European pitch, or 2-inch teardrop US configuration) is executed on computerized high-speed mechanical press banks before roll-forming, guaranteeing hole pitch accumulative tolerances within $\pm 0.5\text{ mm}$ across an entire 12-meter upright column.
