To assure the highest quality products, Hapco poles are structurally designed to stringent specifications that meet or exceed American Association of State Highway & Transportation Officials (AASHTO) standards. Not all manufacturers design to AASHTO, which is conservative by nature, assuring that Hapco designs are the safest, highest quality and longest lasting available in the industry.
Quality Assurance System
Fully embracing our Quality Assurance System begins with strict raw material specifications. Round Aluminum shafts are constructed of seamless aluminum alloys conforming to American Society for Testing and Materials (ASTM). Shaft tolerances are 50-60% tighter than industry accepted standards, leading to greater efficiencies in the manufacturing process and unequaled finished product quality. Required welding is performed by American Welding Society (AWS) / Canadian Welding Bureau (CWB) certified welders to AWS Specification D1.2 or CWB Specification W 47.2 standards. All light pole shafts are heat treated after base weld to a full T6 temper in computer controlled ovens certified to meet the requirements of ASTM B597 and Mil-H-6088 specifications.
In addition, all component parts meet applicable ASTM standards. Components follow a strict initial standard inspection process, followed by a first and fifth piece inspection at each step of the manufacturing process. A final inspection of finished products ensures a level of quality only available with Hapco.
Hapco’s recent ISO9001:2015, AISC and CWF certifications has strengthened our decades long commitment to offer products of the highest quality at ever-increasing service levels.Read More
