Sigrist brand housings and curbs are manufactured in the United States using .125” thick aluminum.

We use computer guided laser cutters and metal forming machines. The seams and joints are all hand welded to insure a weather-tight housing and lid.

Sigrist Pipe Chase Housings are finished using a UV inhibited powder coating material that is electrostatically bonded creating a uniform .2mil thick finish.
