Mezzanines are a great and affordable way to increase your warehouse space. By adding a mezzanine or mezzanine system to your warehouse, you utilize the air space to increase storage or office space. Several different types of mezzanines are available, from free standing to rack supported. By installing a free standing mezzanine the area below would remain open, allowing for office areas or other storage. Free standing mezzanines use structural steel for support. By utilizing a rack supported mezzanine, not only is the area of the mezzanine usable for shelving storage, but the area below is designed for maximum storage with the use of pallet racking.
