Arthur Smith Industries. Established in 1965, by Arthur Smith III, Grandson of the founder of the A.O. Smith Corporation, Mr. Smith began manufacturing fiberglass cold storage doors for the food industry under the ENVIRO brand name. But the company’s growth did not occur until it was purchased by George Balbach in 1974. At that time ASI was the first and only U.S. manufacturer of fiberglass doors. Today, ASI manufactures a comprehensive selection of high performance door systems for the pharmaceutical, refrigerated, government security and commercial markets.
Cleanseal Cleanroom Door systems, Enviro Cold Storage Door Systems and Marathon High Speed, High Performance Door Systems are all designed, engineered and precision manufactured at our corporate headquarters and manufacturing facility located in Milwaukee, WI.
