AB&I has a long legacy in the community. We are committed to being a good neighbor and protecting the health and safety of the entire community. California’s air quality regulatory requirements are among the toughest in the country and we utilize state-of-the-art pollution control technology and operational best practices that not only meet, but often exceed the standards. Here at AB&I, we manufacture quality cast iron soil pipe that is used in commercial and residential plumbing systems. Plumbing infrastructure is critical to public health and sanitation and to healthy communities.
