What are pedestals and why are there different types (i.e. standard, low-profile, heavy duty)?  And which one will I need?
Pedestals are understructure components that support the panels and equipment above. You may think of them as specialized stanchions that hold up a raised floor. Generally they are made of varying thicknesses of steel (which influences overall strength), and the type you need for your project are typically determined by a structural engineer. They will base their calculations and recommendations on a number of factors, including the seismic zone your site resides in, the height of the building and its foundational strength, and the weights and types of activities the raised floor is expected to support.
