View DetailsIn modern industrial logistics infrastructure, the pallet rack upright column serves as the primary vertical load-bearing member responsible for transferring dead loads, live storage loads, and dynamic seismic impact forces downward into the concrete floor slab. As a leading China pallet rack upright dimensions manufacturer and supplier, Guake Logistics Technology manufactures cold-formed steel upright profiles precision-engineered to meet stringent international performance criteria.
The structural capacity of a racking frame is fundamentally governed by the cross-sectional geometry, material yield strength ($f_y$), material thickness (gauge), section modulus ($Z_x, Z_y$), and unbraced frame length ($L_u$). China's advanced cold roll-forming lines allow for complex multi-rib upright profiles that maximize torsional rigidity while maintaining optimal material efficiency.
Key Takeaway: Upright strength is not determined solely by steel thickness. The geometric profile configuration—specifically the presence of multiple continuous stiffening ribs along the column web and flanges—significantly increases the section modulus and delays localized buckling under eccentric axial compression.
The following engineering data table outlines the standard structural upright profiles manufactured in China for heavy-duty selective pallet racking, drive-in racking, and automated warehouse applications:
| Profile Dimension (mm) | Standard Gauges (mm / Gauge) | Steel Grade Options | Section Area ($cm^2$) | Inertia $I_x$ ($cm^4$) | Max Frame Capacity (kg)* | Primary Application Standard |
|---|---|---|---|---|---|---|
| 80 × 60 mm (3.15" × 2.36") | 1.5mm, 1.8mm, 2.0mm (16Ga - 14Ga) | Q235B / Q355B (SS400) | 3.45 - 4.52 | 28.5 - 36.2 | 8,000 - 11,500 kg | Light/Medium Duty, Shelving Units |
| 90 × 70 mm (3.54" × 2.75") | 1.8mm, 2.0mm, 2.3mm, 2.5mm | Q235B / Q355B / Grade 50 | 4.85 - 6.42 | 48.2 - 62.8 | 12,000 - 16,500 kg | Standard Selective Pallet Racking |
| 100 × 70 mm (3.93" × 2.75") | 2.0mm, 2.3mm, 2.5mm, 2.75mm | Q355B / High Yield SS | 5.60 - 7.55 | 68.5 - 90.1 | 17,000 - 21,000 kg | Heavy-Duty Racking & Multi-Tier |
| 120 × 95 mm (4.72" × 3.74") | 2.3mm, 2.5mm, 2.75mm, 3.0mm | Q355B / Q460 Micro-alloy | 8.20 - 10.85 | 142.0 - 185.0 | 22,000 - 28,000 kg | Drive-In, High-Bay & Shuttle Systems |
| 140 × 95 mm (5.51" × 3.74") | 2.5mm, 2.75mm, 3.0mm, 3.25mm | Q355B Structural Grade | 10.50 - 13.60 | 215.0 - 278.0 | 30,000+ kg | ASRS Automated Super-High Bay |
*Note: Maximum frame load capacity is calculated based on a maximum unsupported beam level height (unbraced pitch) of 1,500mm according to FEM 10.2.02 and ANSI MH16.1 specifications.
China's manufacturing ecosystem supports all global standardized hole pitch formats, ensuring perfect compatibility with existing regional storage assets.

The standard boltless design in North America. Features slide-in teardrop holes allowing universal compatibility with standard US beam connectors and automatic gravity safety locks.
Calculating the axial capacity of a cold-formed upright profile requires analyzing elastic and inelastic column buckling. Unlike hot-rolled structural steel I-beams, thin-walled cold-formed steel sections are subject to three distinct buckling modes under load:
The nominal axial compressive strength ($P_n$) of an upright column section without perforations is derived from Euler's critical buckling formula, modified by empirical reduction factors for cold-formed perforations:
$$P_{cr} = \frac{\pi^2 E I_{eff}}{(K \cdot L_u)^2}$$
Where: E = Modulus of Elasticity ($2.05 \times 10^5 \text{ N/mm}^2$), $I_{eff}$ = Effective Moment of Inertia accounting for hole punches, K = Effective length factor (typically 0.9 - 1.0 for anchored baseplates), and $L_u$ = Unbraced distance between vertical beam levels or frame diagonal bracing nodes.
When selecting pallet rack upright dimensions from China suppliers, structural engineers must verify that the net section properties account for the reduction in cross-sectional steel area caused by punch patterns. At Guake Logistics Technology, finite element analysis (FEA) software simulates static and dynamic loading scenarios to validate frame integrity prior to mass production.
Upright column bases convert high vertical concentrated load vectors into distributed surface pressures on the warehouse floor slab. Guake supplies specialized baseplate options:

Expert engineering answers regarding China pallet rack upright dimensions, material grades, load formulas, and global shipping options.
Selecting the proper upright profile depends on three main variables: the total combined load per bay (sum of all beam level capacities), the vertical distance between beam levels (unbraced height), and seismic zone factors. For standard pallet racking carrying up to 10,000 kg per frame with 1.5m beam spacing, a 90×70×1.8mm or 2.0mm profile is standard. For heavier loads exceeding 15,000 kg or tall frames above 8 meters, choose a 100×70mm or 120×95mm profile with a minimum thickness of 2.3mm or 2.5mm.
Yes. Guake Logistics Technology offers full custom OEM roll-forming services. Send us your CAD drawings or physical profile samples. Our toolmakers can design custom cold-roll forming dies and punch tooling to match legacy hole patterns (including 50mm pitch European, 75mm pitch Australian, or 76.2mm teardrop American formats).
Q235B steel has a minimum yield strength ($f_y$) of $235 \text{ N/mm}^2$ (equivalent to ASTM A36 / SS400). Q355B is a high-strength low-alloy steel with a minimum yield strength of $355 \text{ N/mm}^2$ (equivalent to ASTM A572 Grade 50). Using Q355B allows engineers to specify thinner gauge steel while achieving up to 30% higher load bearing capacity, making it ideal for tall pallet rack frames and heavy-duty industrial storage platforms.
Powder coating (epoxy-polyester, 60-90 microns) is cost-effective, highly durable, and suited for 90% of dry indoor warehouse applications. Hot-dip galvanizing (ISO 1461, 60-100 microns metallurgical zinc coating) is recommended for cold storage rooms (-30°C), outdoor exposed yards, or highly corrosive chemical storage environments where moisture condensation causes raw steel oxidization.
Upright frames can be shipped either knock-down (unassembled upright columns and diagonal/horizontal bracing packed separately to maximize sea container space) or pre-assembled (welded or factory-bolted). Components are bundled using heavy-duty steel strapping, fitted with plastic corner guards, wrapped in moisture-proof stretch film, and mounted on timber dunnage to enable forklift unloading at destination ports.
