CRL U.S. Aluminum Extrusions

are made in the U.S.A. to the exacting standards you expect from the leader in aluminum architectural systems. Specific sections are designed to fit together tightly, assuring structural integrity while also providing an aesthetically superior appearance. Stock lengths are available in standard finishes, and we can also provide custom finishes that meet the requirements of your project. Special cut-to-size lengths can also be quoted in standard and custom finishes.

Over the years U.S. Aluminum has created hundreds of custom extrusions to satisfy specific job requirements. If it can be extruded, we have probably seen it, from rounded center glaze sills to extended curtain wall face caps, and everything in between. Please note, custom extrusions are subject to a minimum order, and in some cases die charges. These will be detailed in your quote request.
