GLSEC's full service materials testing laboratories are among the finest in the
Chicagoland. Although our facilities are located in the Chicago area, we routinely
receive test samples from clients throughout the United States. Our proprietary
data management system provides up to date information on the status, performs thorough
quality control and allows clients to access test reports online. The quality of
work performed by us is better demonstrated by the certifications we possess from
various regulatory agencies.
