. . . Arcelor Mittal just produced rails for Kansas City. Why is it necessary to buy tracks overseas?

I was curious about one agency sourcing in the U.S. and another sourcing off-shore so I did some cursory checking on the ArcelorMittal product.
ArcelorMittal rolls “block rail,” called TRAM112. Block rail is similar to but different from the traditional “girder rail” having a more compact “squat” cross section than girder rail. ArcelorMittal highlights some advantages of their product here:

ArcelorMittal uses technology imported from the “sister” mill in Poland at the Pennsylvania mill. As far as I can tell, Block rail is a “sole source” product, available only from ArcelorMittal. Looking at the profile, I believe other track components, such as switch points and frogs, would have to “match” this rail profile. These components are also likely available only from limited sources. This could cause an agency to shy away from using the product, regardless of any advantages.
Several other US transit agencies have used block rail:
“The Waterfront Moody Avenue Improvement Project in Portland, Oregon, the South-eastern Pennsylvania Transit Authority (SEPTA), New York City Transit and Washington Metro are all examples of prior usage of the TRAM112.”
The photos indicate El Paso is using traditional “girder rail.” AFAIK, no US mill rolls this product.
It would be interesting to know what factors were considered in selecting the rail profile for these projects.
