Abstract
Overview
ISO 657-19:1980 - "Hot-rolled steel sections - Part 19: Bulb flats (metric series) - Dimensions, sectional properties and tolerances" - specifies the geometry, sectional properties and production tolerances for metric-series bulb flats produced by hot rolling. The standard defines designation rules, tabulated dimensions and sectional data (mass, area, centroids, moments of inertia and section moduli) and the acceptable dimensional tolerances and shape limits used for design, procurement and quality control.
