An exterior coiling door installation set within a concrete encasement around a structural steel member. Corner protection is provided by a 3x3x1/4-inch galvanized steel angle with 1/2-inch diameter studs spaced at 1 foot on center, set flush with the face of the concrete and extending to a height of 4 feet from the finish floor. The assembly incorporates a 1/4-inch stainless steel plate, metal tees, and additional framing angles positioned beneath the slab edge above. Precise alignment dimensions establish the centerline of the coiling door, recess clearances, and overall wall thickness relative to column grid lines.
