2015 Quality Award Recipients

Quality control is a crucial aspect of all manufacturing processes. Therefore, Member fabricators of the Steel Tank Institute's licensed tank technologies are subject to periodic, unannounced inspections by a team of STI/SPFA QC Inspectors. STI/SPFA QC Inspectors conduct a rigorous investigation of the manufacturing function, to ensure that companies are following all of the requirements of the STI/SPFA Standards for fabrication of licensed technologies.

Quality Award Winners are chosen annually based on above-average ratings for these random inspections. Fabricators are required to produce a minimum number of fabricated units to qualify as a Quality Award recipient in these categories:

  • SILVER: Three consecutive years with no QC non-compliance tags
  • GOLD: Five consecutive years with no QC non-compliance tags
  • PLATINUM: Ten consecutive years with no QC non-compliance tags
  • DIAMOND: Fifteen or more consecutive years with no QC non-compliance tags
