Mustang Metal was originally established as a masonry supply company about 1975, serving masonry contractors in the Houston area. It was purchased shortly thereafter by Blumenthal Sheet Metal Co. as a subsidiary company. Mustang slowly evolved to the fabrication of stone anchors for marble and granite and other miscellaneous metal products. In 1993, Mustang was sold to Dan Lubbock and moved to the larger facility where it is now located.
