CRL-U.S. Aluminum Extrusions (SKU: 0G56499) are made in the U.S.A. to the exacting standards expected from a leader in aluminum architectural systems. Sections are engineered to fit tightly for structural integrity and a clean, professional appearance. We stock standard lengths and finishes and offer custom finishes and special cut-to-size extrusions to meet project specifications.

Over the years U.S. Aluminum has produced hundreds of custom extrusions—from rounded center glaze sills to extended curtain wall face caps—so if it can be extruded, we’ve likely engineered a solution.
NOTE: Custom extrusions may be subject to minimum orders and die charges; details will be provided with your quote request.
