DirecTank is committed to quality in every step of the manufacturing process.  We understand that the ultimate quality of our products is dependent upon a collaborative process that requires each individual supplier, manufacturer, and process to meet our rigorous standards.

We subject our entire supply chain to a thorough evaluation and continuous audit process.  All of the raw material that we use comes from reputable, highly scrutinized suppliers that provide us with complete mill certifications.

Most AST Products companies would either not go that far or just stop right there, but we don’t.  At DirecTank we don’t take short-cuts.  We use independent testing labs to verify upon receipt that all critical components within our supply chain either meets or exceeds the appropriate specifications.

With an ongoing QA/QC audit program, our dedicated team of engineers and quality managers, with the full support and oversight by our executive team, promote continuous improvement throughout the entire process, thus reducing and eliminating non-conformities, and most importantly preventing our customers from costly problems in the field.
