CRL-U.S. Aluminum Extrusions (SKU: BT81571) — made in the U.S.A. to exacting standards for architectural aluminum extrusions. Sections are designed to fit tightly for structural integrity and a clean, high-end appearance. We offer stock lengths with standard finishes and can supply custom finishes or special cut-to-size aluminum extrusions to meet project requirements.

Over the years U.S. Aluminum has created hundreds of custom extrusions to satisfy specific job requirements — from rounded center glaze sills to extended curtain wall face caps. If it can be extruded, we’ve likely produced it.
NOTE: Custom extrusions may require minimum orders and, in some cases, die charges. These details will be provided in your quote.
