In business since 1957, SST has become a major importer and manufacturer in the United States, serving a diverse customer base. SST has offices both domestically and worldwide, from which we base a staff of field engineers and production workers who continually monitor and audit production before, during and after the manufacturing process. When the products are complete, we inspect them in accordance with our Quality Assurance Procedure (QAP) prior to their being placed in the warehouse. Generally, an adequate supply of finished goods is maintained at SST to ensure J.I.T. shipments to our customers.
