USA Manufacturing

Here at Lowbrow Customs we believe strongly in supporting US manufacturing. We have created multiple annual scholarships, one with the Lincoln Electric Welding School and another with Tri-C (Cuyahoga Community College) for students in financial need who are pursuing workforce training. From TIG welding to machining, this is the backbone of manufacturing in the United States. Want to learn more? Click here.
