American Flagpole embraces a full Quality Assurance System that begins with exacting raw material specifications.

Required welding is performed by AWS certified welders to AWS Specification D.1.1 standards (CWB and CSA certified welders to Canadian specification code W 47.2.), and all flagpole shafts are heat treated to a full T6 temper. In addition, all component parts follow a strict standard inspection process, ensuring a level of quality only available with American Flagpole.
