Supporting capabilities include accredited mechanical testing (tension, bend, compression, impact, macrographic examination), on-site heat treatment via six transportable units totaling 700 KVA, and welder certification under EU Pressure Equipment Directive 2014/68/EU.

The company monetizes through project-based professional services contracts, dispatching certified technicians on-site to refineries, power plants, and industrial construction sites, supplemented by laboratory-based testing and recurring certification work. GATS is accredited under ISO 17025 and EN 17020 by the Hellenic Accreditation Council (ESYD), holds ISO 9001:2015 and ISO 45001:2018 certifications, and has been ISO-certified by Bureau Veritas since 1991. Its customer base is concentrated in Greek energy and heavy industry — most notably an exclusive NDT supplier relationship with Hellenic Petroleum's (ELPE) Thessaloniki refinery since 1977 — alongside Motor Oil, Public Power Corporation, DEPA, Titan Cement, METKA, AKTOR, Aluminium of Greece, and others. International projects have been executed in Iraq, Saudi Arabia, Libya, and Bulgaria. GATS works in close cooperation with classification bodies Bureau Veritas, Lloyds Register, and American Bureau of Shipping, and operates with a reported 11–50 employees across its two Greek laboratories.
