An aluminum beam and grating assembly is anchored to a concrete wall using 6x4x1/4-inch aluminum bent plates secured with three-quarter-inch diameter stainless steel anchor bolts with eight-inch embedment at 18 inches on center, alongside 3/8-inch diameter by 4-inch stainless steel countersunk concrete anchors at 24 inches on center. The aluminum beam supports an aluminum grating and connects via an aluminum angle 4x4x3/8-inch where grating occurs. Aluminum stiffener plates are spaced at 24 inches on center, alternating with 5/8-inch diameter stainless steel bolts at 24 inches on center. Fillet welds of 3/16-inch size are applied on two sides as indicated.
