About Us
Serving the El Paso Southwest for over 100 years

KASCO Structures, LLC, formed in 2014, integrates years of experience from our legacy companies as reflected in our structural steel, roofing & manufacturing operations.

Originating with sheet metal fabrication and commercial roofing in 1913 as Southwestern Sheet Metal Works, Inc. and Southwestern Roofing, Inc., and continuing with our acquisition in 1978 of El Paso Machine and Steel, Inc. the leading manufacturer of structural steel in the region since 1920, we have continued to innovate and grow over the years.

Our manufacturing operations specialize in close tolerance, high quality steel fabrication which allows us to fully service specific industries with complete design, engineering and fabrication services. As such, KASCO Structions provides structural integrity of our connection designs which meet or exceeds all requirements.

In addition to our commercial roofing installations, KASCO manufactures roof metal panels under our Metallo Roof System brand. The roof panels are produced in our El Paso plant and can also be formed on the job site.

Very Truly Yours,
William F. Kastrin
