About this detail

A structural steel gusset plate for maintenance tie-off is welded or anchored to a finish-painted steel upstand, which bears upon a finish-painted structural steel pipe arch. The assembly includes a two-inch diameter opening for the tie-off point isolated with an ethylene propylene diene monomer gasket. A clear anodized aluminum extrusion is secured over the penetration with four stainless steel bolts, nuts, and washers at each upstand. Three lines of silicone weather sealant are applied all around the penetration in the extrusion and cap plate to provide weatherproofing. The gusset plate is engineered to withstand a five-thousand-pound load in any direction without permanent deformation and is spaced at twelve feet on center typically.
