Raised Floor Loading Capacity & Weight Rating | How Much Weight Can A Raised Access Floor Support?

2019/9/17 19:27:08

How much weight can a raised floor hold? How to calculate raised access flooring system loading capacity? How much weight capacity required for different applications of raised access floor? Regard to the weight capacity and load rating of the raised floor, AccessFloorStore.Com will give you the most detailed and in-depth explanation with years of access floor manufacturing experience.

Raised Floor System Weight Load Capacity Explained

As you known, with the vary benefits of Raised Flooring Systems, such as allow services (cables, wires ) to be hidden in a void created in the floor and enable easy access both when installing and maintaining the services, we can find access floors are widely used in in special working environments with high load requirements, for example computer room, data center, modern office, library, etc.. While these workplaces are generally with heavy, bulky equipment exhibited inside, the total weight of it all can be staggering, Safety factor including weight capacity is a measurement with which your raised floor system was designed to support loads without collapsing. 

What is the Weight Loading Capacity of Raised Access Flooring System? 

Simply to say, weight capacity is just that - how much weight the raised floor system will hold, also refer to load-bearing capacity. Load capacity refers to the maximum demand, stress, or load that may be placed on a given Raised Floor System under normal or otherwise specified conditions for an extended period of time. In other words, it refers to the capacity of an access floor system to continue to perform its intended function when supporting a specific amount of weight. In short, in a raised flooring system, load capacity usually pertains specifically to the maximum demand, stress, or load that can safely be placed upon a raised access floors without causing it to fail. 

How Much Weight Can a Raised Access Floor Hold?

The weight load capacity range for standard raised access flooring is from 1,000 to 2,000 pounds

While for different applications, different Floor Loading Capacity is required. For example: to maximize floor space, the cabinets that most data centers use can handle 2,500-3,000 pounds of hardware, and the raised floor for data center has to be sturdy enough to hold that weight; while light traffic areas are built with the typical 1,000 to 1,500 pound panels. For seismically active regions, further support may be required–usually, additional pedestals, stringers, and floor panels.

How to calculate Raised Floor Loading Capacity? 

Ratings of Loading to consider when you are planning to build a raised access flooring system:

Concentrated Load - To determine the maximum deflection(s) and permanent set(s) of an access floor under load.

Ultimate Load - To determine the maximum deflection(s) and permanent set(s) of an access floor under load.

Rolling Load - To determine the durability and/or deformation of an access floor system when exposed to commercially anticipated caster traffic using a specific load.

And more . . .

HuiYa Raised Floor Loading Capacity

To determine these load ratings of the raised floor, the best way is to pass the CISCA - Recommended Test Procedures for Access Floors, which including the most comprehensive testing system of raised floor loading. Huiya Raised Floor is manufactured strictly in accordance with American CISCA "Recommended test procedures for access floors", and you can check out the confirmed  loading capacity of our raised floor systems in different materials on the below tables:
