Heavy-duty Rack Load and Safety Guide

Per-level load and uniformly distributed load. The rated load on a rack is usually the uniformly distributed load per level. Concentrated load (goods piled in one spot) puts more pressure on beams and uprights and should be calculated with a more conservative value.

Load calculation. The specifications of uprights, beams and shelves are jointly calculated from span, level spacing and load. The longer the beam span and the higher the load, the larger the steel section required — do not rely only on the per-level rated value.

Safety factor. A proper design reserves a safety margin beyond the rated load. Actual loading should stay within the rated range, taking into account dynamic factors such as forklift impact and eccentric goods.

Overloading or uneven distribution can cause beam bending and upright instability, bringing the risk of goods falling. Load goods according to the design capacity, place them evenly, and post load-limit signs in visible positions.

Regularly check whether uprights are vertical, beams are deformed, connecting clips are loose and column protectors are intact. Handling any abnormality promptly is an important part of safe rack use.
