Guardian: Making History Since 1932

As much as we'd like to know about you, there's probably a lot you want to know about us.

We don't mind telling you that Guardian is one of the world's largest manufacturers of float glass and fabricated glass products. You should also know that we manufacture and supply the automotive industry with a variety of exterior products. We've also become a significant player in the building materials distribution business. And somewhere along the line, we became one of the world's largest producer of mirrors.
Headquartered in Auburn Hills, Michigan, the privately held Guardian group of companies employs 17,000 people worldwide and we value them above all else.
Through its Science & Technology Center, Guardian is at the forefront of innovation including the development of high performance glass coatings and other advanced products.  Researchers work continuously to make glass perform in new ways—solving the customer needs of today and discovering the potential of glass for tomorrow.
At Guardian, we work hard to create value for our customers and society by making products that improve people's lives.
