CRL-U.S. Aluminum Extrusions (SKU: RT45022) are made in the U.S.A. to the exacting standards you expect from a leader in aluminum architectural systems. Precision-extruded profiles are engineered to fit together tightly for reliable structural integrity and an aesthetically superior appearance. We offer stock lengths in standard anodized and painted finishes, plus custom anodized, painted, and specialty finish options to meet project specifications. Special cut-to-size aluminum sections and quick-quote fabrication are available for architectural projects requiring exact lengths and tolerances.

U.S. Aluminum has produced hundreds of custom extrusions—everything from rounded center glaze sills to extended curtain wall face caps—so if it can be extruded, we’ve likely done it. Note: custom extrusions may be subject to minimum order quantities and die charges; details will be provided in your quote.
