Structural Arms

Structural arms are available in various lengths, which include 12”, 18”, 24”, 30”, 36”, 42”, 48”, 54”, 60”, 72”, 78”, 84”, 90”, and 96”. The arm plate connection is identified as 3”MD, 4” MD, 4”HD, 5” HD, 5.5” HD, and 6” XHD, which indicates the spacing between each punched bolt hole. The plates are either 1\2” thick or 5\8” thick and have four ø13/16” or ø 1/2” punched holes at each corner. The plate requires 4-ASTM A325 structural bolts specified and tested for this specific purpose. These bolted connections fix the arm to the rack column on one end, leaving it free on the opposing end, thus resulting in a cantilever rack arm. The arms are designed to resist uniformly distributed loads exerted by the product that is supported and shall be manufactured of structural S-sections, W-sections or equivalent structural profiles. The supported load should be centered on the arm and should refrain from exceeding the edge of the arm. The arms are used for interior and exterior purposes. For all applications, the arms are finished with a powder-coated Cogan standard grey paint, which provides ultra-resilient protection.
