Ideal Group President Loren Venegas talks with Crain's Senior Reporter Chad Livengood about how the company his brother founded in 1979 has grown from a steel fabrication business into a multifaceted enterprise that designs and builds bumper post bollards for major retailers, sells obsolete auto factory machine parts around the world and does general construction contracting. In 1995, founder Frank Venegas Jr. began moving his business from Livingston County to a shuttered General Motors plant on Clark Avenue in southwest Detroit's Mexicantown.
