EFCO Corp. introduced its new 590X Steel Replica Window, which replicates the look of a classic, industrial steel window in a choice of three standard profiles—bevel, cove and t-grid—or in made-to-order options. Finishes also can be specified with different colors on the exterior and interior to complete the desired architectural aesthetic. Applications include new construction or renovation of mid-rise buildings such as schools, universities, student residences, courthouses, hospitals, offices, retailers and properties on the National Register of Historic Places.
