Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard is not equivalent to Japanese JIS G3192-2008 "Dimensions, Mass and
Permissible Variations of Hot Rolled Steel Sections".
This standard replaces GB/T 11263-2005 "Hot-rolled H and Cut T Section Steel".
Compared with GB/T 11263-2005, the main changes of this standard are as follows.
— The types of H450×150, H475×150, H500×150 and H625×200 series and the
specification of H298×201×9×14 for H300×200 series were added.
— HP series and thickness dimension requirements were added.
— Values such as section area, theoretical weight and section characteristic
parameter were adjusted.
— For permissible deviation of dimension and shape of H section steel, the flange
bending and outer edge passivation requirements of flange leg end were added.
— The original Appendix A "Common Steel Designation and Mechanical Property
of Hot-rolled H Section Steel" was deleted, and Appendix A was changed into
"Rewelding Supplement Regulations for H Section Steel and Cut T Section
Steel".
— In Appendix B, the comparison for type and section characteristic parameter of
newly added joist steel and H section steel was updated.
— Appendix C "Section Dimension, Section Area, Theoretical Weight and Section
Characteristic of Over-thick and Overweight H Section Steel" was added.
Compared with JIS G3192-2008, the main changes of this standard are as follows.
— H section steel is divided into four categories according to wide flange, middle
flange, narrow flange and thin wall.
— 19 types for thin wall category were added.
— Types of H450×150, H475×150, H500×150, H550×200, H550×300, H625×200,
H650×300, H750×300, H850×300 and H1000×300 and other 19 specifications
were added.
— Partial cut T section steel type series were added.
— In Table 3, the thickness t1 was added with a column "less than 5mm"; the
Hot-rolled H and Cut T Section Steel
1 Scope
This standard specifies the ordering content, classification, code, dimensions, shape,
weight and permissible deviation, technical requirements, test methods, inspection
rules, packaging, marking and quality certificate of hot-rolled H section steel and T
section steel cut by hot-rolled H section steel.
This standard is applicable to hot-rolled H section steel (hereinafter referred to as "H
section steel") and T section steel cut by hot-rolled H section steel.
