Foreword
GB/T 34560 “Structural steels” is divided into 6 parts:
- Part 1: General technical delivery condition for hot-rolled products;
- Part 2: Technical delivery conditions for structural steels for general
purposes;
- Part 3: Technical delivery conditions for fine grain structural steels;
- Part 4: Technical delivery conditions for high yield strength quenched and
tempered structural steel plates;
- Part 5: Technical delivery condition for atmospheric corrosion resisting
steels;
- Part 6: Technical delivery conditions for seismic-improved structural steels
for building.
This Part is Part 5 of GB/T 34560.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009.
This Part uses redraft law to modify and adopt ISO 630-5:2014 “Structural
steels - Part 5: Technical delivery conditions for structural steels with improved
atmospheric corrosion resistance”.
This Part, compared with ISO 630-5:2014, has structural adjustments. Annex A
lists a comparison table of clause-subclause number of this Part and ISO 630-
5:2014.
This Part, compared with ISO 630-5:2014, has technical differences. The
clauses involved in these differences have been marked by a vertical single line
(|) at the blank of the outer margin. Annex B gives a table of the corresponding
technical differences and their causes.
This Part also makes the following editorial changes:
- Delete Bibliography of ISO 630-5:2014;
- ADD informative Annex F;
- ADD informative Annex G.
This Part was proposed by China Iron and Steel Association.
Structural steels - Part 5: Technical delivery condition
for atmospheric corrosion resisting steels
1 Scope
This Part of GB/T 34560 specifies the terms and definitions, classification and
designation representation, order content, dimensions and tolerances on
dimensions, shape, and mass, technical requirements, test methods, inspection
rules, packaging, marking, and certification of atmospheric corrosion resisting
structural steels.
This Part applies to steel plates and strips, wide flats, section steels, and bars
(hereinafter referred to as “steels”) with nominal thickness or diameter not
exceeding 200 mm for welding or bolting.
