Product Details:

Suspended ceilings are secondary ceilings suspended from the structural floor slab above, creating a void between the underside of the floor slab and the top of the suspended ceiling. The gap between a suspended ceiling and the structural floor slab above is often between 3 to 8 inches which is why they are often referred to as dropped ceilings or false ceilings...

Product Details:

hollow structural steel. Rectangular and square HSS are also commonly called tube steel or box section. Circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimensioned and classed differently from HSS. (HSS dimensions are based on exterior dimensions of the profile; pipes are also manufactured to an exterior tolerance, albeit to a different standard.) The corners of HSS are heavily rounded, having a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.
