Calcium Sulphate Raised Flooring VS Steel Raised Flooring

There are many differences between Steel and Calcium Sulphate Raised Flooring. We will analyze from the following points and let’s take a look.

Characteristics of calcium sulphate raised flooring and steel raised floor


Steel raised floor is made of good quality cold rolled steel sheet, which is stretched, spot welded, and coated with epoxy powder after having been phosphated. There is foaming cement fully filled, with corner-lock holes pouched in four sides of panel.

Calcium sulphate panel is made of high strength calcium sulphate core. The top surface can be stuck with all kinds of covering, the bottom can be covered with aluminum foil or galvanized steel sheet. Four edges are sealed with PVC edge trim.

difference between steel and calcium sulphate

Fire Resistance

Calcium sulphate raised floor shows the best fire resistance in a variety of raised floors, so it offers the most valuable solution for safety. Steel raised floor is also fireproof, but it performed not as well as calcium sulphate raised floor in high temperature environment.


Its maintenance and cleaning are easier, and the floor life is longer than the steel raised floor.

Recyclable Rate

The recyclable rate of calcium sulphate panel is about 80%. It is made of natural natural gypsum powder and reinforced fiber(primary and secondary fibers). But the steel raised floor can’t be recycled or it is difficult to recycle the steel after produced because of the foaming cement inside the steel raised floor.

Acoustic performance

The calcium sulphate panel provide excellent acoustic values. There is noise when walking on the steel floor at the first period after installation or moving heavy equipment on it.

Market factors of calcium sulphate raised flooring and steel one


The price of calcium sulphate raised flooring is higher than the steel raised floor. Under the same concentrate load of FS1000(454KGS),the price is higher than the steel raised flooring.

Applicable place

Both of them apply for data center. The calcium sulphate raised flooring is also suitable for the workplace which has strict ground requirements, such as dust proof and fireproof. In recent years, the demand of it soaring. This kind of situation arises from its unique performance advantage.
