Austin Mohawk, Inc. was created in 2004 with the merging of Austin Fabricating, Inc., (buildings and shelters) and Mohawk Manufacturing, Inc. (canopies), two longtime sister companies. In their respective industries, each was among the oldest and most well respected manufacturers. Together, we expect to bring an even stronger and more integrated product line to our customers.

Austin Mohawk has spent more than 80 years building superior quality, prefabricated metal structures. Our product lineup includes pre-manufactured buildings, shelters, and metal canopies. Prefabricated or factory-built structures have significant advantages over site-built constructionincluding economy, speed, quality, and flexibility. Our prefabricated metal buildings and booths can be custom built in aluminum or steel. From security buildings to cashier booths to parking booths, our custom built booths and buildings are modular, functional, and aesthetically pleasing. Our metal canopies and walkway covers are designed, fabricated and shipped for on-site erection.
