Advanced Testing and Materials Inc. provides a broad range of materials engineering, materials testing, and QA/QC services for the design and construction of new projects as well as the investigation of existing structures. ATMI’s professional and technical staff can perform standard test methods and modify or develop new test procedures to fit the needs of any particular project.
