Scope
This document specifies the terms and definitions, classification and designation, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of steel sections used in steel box girders (hereinafter referred to as "steel sections"). This document applies to hot-rolled steel sections used in the main load-bearing components of steel box girders in highway, railway, and municipal bridges, including H-section steel (primary crossbeams and horizontal beams), I-section steel (secondary beams), channel steel (supporting members), and angle steel (connection nodes). It does not apply to special alloy steel sections (such as stainless steel sections and heat-resistant steel sections) and non-load-bearing decorative steel sections.
