CRL-U.S. Aluminum Extrusions are made in the U.S.A. to exacting standards for architectural aluminum systems. Engineered sections fit together tightly to ensure structural integrity while delivering a clean, professional appearance. We offer stock lengths in standard anodized and painted finishes, plus custom finishes and precision cut-to-size extrusions to meet project specifications.
Over decades, U.S. Aluminum has produced hundreds of custom extrusions—from rounded center glaze sills to extended curtain wall face caps—serving diverse architectural and commercial projects.
