Guardian Industries is a privately held industrial manufacturer of glass, automotive and building products based in Auburn Hills, Michigan. It is one of the world leaders for float glass, fabricated glass products, fiberglass insulation and building materials for commercial, residential and automotive markets. The company employs over 19,000 people all over the world and has present activities in North and South America, Europe, Asia, Africa and the Middle East.
Guardian Industries was founded in 1932 as Guardian Glass Company. This world leader in glass, automotive and building products got its start as a small windshield fabricator. In 1957, the same year Guardian filed for Chapter 11 bankruptcy, William Davidson became president of Guardian, 10 years after he graduated from the University of Michigan in 1947. After three years in 1960, Guardian came out of bankruptcy. In 1968, the company officially changed its name to Guardian Industries Corp. and under William Davidson’s leadership; they went public with the initial trade valued at $17 a share. The following year Guardian began trading on the American Stock Exchange.
In 1970, Guardian faced the most important development within its history: they started producing flat glass with the newly invented float glass process. Therefore, they opened their first production line in Carleton, Michigan and today the company counts 28 float glass lines and 13 glass fabrication plants around the world. In 1973 it began trading on the New York Stock Exchange. From on 1980, Guardian started to diversify its activities and they started the production of fiberglass insulation. The European market entry took place in 1981 when the company opened their production line in Bascharage, Luxembourg. Further plants came up in Germany, Spain, England, Hungary and Poland. The company went back to a privately held company in 1985 after 17 years as a public company.
In the 90’s, Guardian could note down an upswing both in the sectors construction materials and automotive products due to several takeovers and acquisitions: Automotive Moulding Company Warren, Michigan; Lab. Radio from Valencia, Spain; Builder Marts of America (BMA) and Cameron Ashley Building Products (which is now the Guardian Building Products Distribution) in 2000. In 1995, corporate headquarters moved from Novi to their present location in Auburn Hills, Michigan. Furthermore, Guardian strengthens its effort in the field of research and development by opening a new science & technology centre in Carleton, Michigan. Due to that, the products of their commercial and residential lines, solar-and electronic devices as well as automotive products can be improved and extended. The takeover of Siegel-Robert Automotive in 2008 led to the formation of SRG Global , one of the world’s largest suppliers of advanced, high value coatings on plastics.
