    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.

    Most shipping weights are approximate and have not been verified. If the exact weight is needed in order to determine shipping costs, and shipping costs are required in order for you to complete your order, please request this prior to submitting your order by contacting CRL Customer Service.
