ANSI O5.2-2020 covers requirements for manufacturing and quality control of structural glued laminated timber of
Southern Pine (longleaf, slash, shortleaf, loblolly), Coast Douglas-fir, Hem-Fir and other species of similar
treatability for electric power and communication structures. The requirements are based on those in American
National Standard for Structural Glued Laminated Timber, ANSI A190.1. This standard is supplemental to ANSI
A190.1 and provides descriptions of the special manufacturing and design requirements for glued laminated utility
structures.
