DIN 1026-1:2009-09

Foreword This standard has been prepared by Subcommittee 21/6 Warmgewalzte Profilerzeugnisse of the Normenausschusses Eisen und Stahl (FES) (Iron and Steel Standards Committee). DIN 1026 consists of the following parts under the general title Hot-rolled steel channels: ⎯

Part 1: Taper flange steel channels — Dimensions, masses and sectional properties

⎯

Part 2: Parallel flange steel channels — Dimensions, masses and sectional properties

Amendments This standard differs from DIN 1026-1:2000-03 and DIN 1026-1 Corrigendum 1:2002:11 as follows: a)

The standard has been editorially revised and normative references updated.

The following corrections have been made to DIN 1026-1:2009-04: a)

Figure 1 has been corrected so that the dimension ey describes the distance of the outer edge of the channel from its y-y axis.
