Cold Roll Mezzanine
Cold rolled refers to the method of bending sheet metal into “c” channel to use as the understructure of the mezzanine floor. These cold rolled pieces attach to the tubular steel or tapered columns and provide the “beams” that support the floor. Cold rolled has two major benefits over structural steel mezzanines. First, the material is much lighter than structural steel and therefore less expensive to ship. This usually means there is also less equipment needed to erect the structure on site. Second, cold rolled steel can be pre-galvanized; offering a substantial savings over hot dipped galvanized, stainless steel, or aluminum mezzanines. A disadvantage of cold rolled steel mezzanine systems is the very limited column spacing (usually 10’ – 15’ max). They are also unable to reach the high live loads or heavily concentrated point loads that can be accomplished with structural steel mezzanine systems.
- Cold rolled systems can be pre-galvanized whereas structural steel must be hot-dipped in order to become galvanized.
- Decking options systems include: B-deck and plywood, bar grating, and plank decking.
- Cold rolled systems will tend to be cheaper (partly due to less freight cost), but offer fewer options and have lower column spacing and load rating maximums.
