What is the maximum span that can be designed for a heavy-duty attic mezzanine?

The design of the span of the second-floor heavy-duty shelving platform is a core issue in warehouse space planning. It directly affects the space utilization rate, structural safety, construction cost, and the convenience of accessing goods. Therefore, it is a concern for many customers. So, how can the span of the second-floor heavy-duty shelving mezzanine be designed? Let's find out.

The primary determining factor for the span is the design load-bearing capacity of the platform. Under the same material specifications, the larger the span, the greater the deflection of the crossbeam when bearing the load. The standard span of the second-floor heavy-duty shelving mezzanine's columns ranges from 2 to 4 meters. For spans exceeding 4 meters, steel structural columns are generally required. A span of 4 meters or more is sufficient for stability, but achieving a larger span such as 6 meters or more faces significant technical challenges and increased costs.

Steel structure mezzanine shelving is generally used for storing goods with high load requirements, such as those requiring a load-bearing capacity of more than 1 ton per square meter. It can be designed with a column span of 4 to 8 meters. This design can reduce the number of columns, increase storage capacity while providing an open layout, flexible layout, and an unobstructed spacious space for forklift aisles and goods turnover, greatly improving operational efficiency and the flexibility of space utilization. However, the cost is also higher than that of ordinary second-floor heavy-duty shelving mezzanine.
