Access floors, also known as raised floors or raised access flooring systems, are a vital part of many commercial and industrial buildings. They offer a practical solution for managing complex wiring, HVAC systems, and other utilities beneath the walking surface, making maintenance and changes much easier. They are more complex than other flooring solutions because they are a raised surface that requires more parts and components.
What exactly makes up these floor systems? Let’s break down the key components of access floors.
Floor Panels
Floor panels are the visible and load-bearing part of the access floor system. They are typically made of high-strength materials like steel, cementitious core, or wood core to support heavy loads. Panels are modular, usually one and a half to two feet square, allowing for easy removal and reconfiguration. The top surface can be finished with carpet, vinyl, laminate, or tile to suit the design and functional needs of the space.
Pedestals
Pedestals are vertical supports that hold up each floor panel. They are typically made from steel and are adjustable in height to ensure a level walking surface. Pedestals are securely fixed to the subfloor with adhesive or mechanical fasteners, providing stability and support to the entire flooring system.
Stringers
Stringers are horizontal support bars that connect pedestals together, providing extra stability and load-bearing capacity. Not all access floor systems use stringers; their use depends on the load requirements and the desired rigidity of the floor. In high-traffic or equipment-intensive areas, such as data centers, stringers are often essential.
Understructure
The combination of pedestals and stringers (if used) makes up the understructure. This framework supports the panels and ensures the entire system remains secure, stable, and level. The height of the understructure can vary based on the amount of space needed for cabling or airflow.
Accessories and Finishes
Access floors often include accessories such as grommets, cable cutouts, air diffusers, and ramps. These add-ons improve functionality by allowing cables, air, or power to reach workspaces efficiently. Additionally, floor finishes help the system blend with interior designs while offering durability and slip resistance.
