In modern logistics warehousing systems, heavy-duty racks serve as the core facilities for bearing bulk goods, and their stability and safety directly affect the efficiency of the entire supply chain. Among them, the upright column acts as the "backbone" of the rack structure, and its load-bearing capacity is particularly critical. Today, let's delve into the secrets behind the load-bearing table of heavy-duty rack uprights to provide a scientific basis for your warehouse planning!
[ Material of Upright Determines Basic Strength ]
High-quality cold-rolled steel is the mainstream choice, enhanced with hot-dip galvanizing for corrosion resistance. Different thicknesses (such as 2.0mm/2.5mm) correspond to different single-layer load limits, usually reaching 800kg-1500kg per set. When selecting materials, factors such as warehouse humidity and cargo corrosiveness should be comprehensively considered.
[ Reference Standard Parameters ]
Taking a common medium-sized warehouse as an example: for racks under 3 meters in height, the upright cross-section size is mostly 80×60mm; if higher storage density is required, it can be upgraded to 100×70mm specifications. It is worth noting that the actual load capacity must deduct a safety factor (a 30% margin is recommended) to ensure no deformation during long-term use.
[ Key Points of Dynamic Load Testing ]
Professional manufacturers conduct simulated stacking tests, including eccentric loading and impact testing scenarios. A quality structural design should achieve uniform stress distribution to avoid localized stress concentration that leads to metal fatigue. It is recommended to prioritize products certified by ISO.
[ Installation Standards Affect Performance ]
The embedded depth of anchor bolts and the precision of level adjustments significantly impact final performance. During construction, use a laser rangefinder to calibrate diagonal errors to less than 3mm, and ensure expansion bolts penetrate the concrete layer by at least 10cm. During regular maintenance, use a torque wrench to check connection tightness.
[ Golden Rules for Model Selection ]
Calculate the required value based on cargo unit weight × number of layers × dynamic load coefficient, then match the model according to the manufacturer's technical manual. For example, in pallet storage plus forklift operation scenarios, it is recommended to use reinforced C-shaped steel upright structures combined with cross braces to enhance overall rigidity.
Mastering these core data and selection logic not only optimizes warehouse space utilization but also builds a safe and reliable material management system. Next time you purchase, remember to bring this guide for in-depth communication with your supplier.
