Foreword
GB/T 1499 “Steel for the reinforcement of concrete” is divided into three parts.
- Part 1. Hot rolled plain bars;
- Part 2. Hot rolled ribbed bars;
- Part 3. Welded fabric.
This Part is Part 1 of GB/T 1499.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009.
This Part replaces GB/T 1499.1-2008 “Steel for the Reinforcement of Concrete
- Part 1. Hot Rolled Plain Bars”. As compared with GB/T 1499.1-2008, the main
changes are as follows.
- ADD some normative references;
- DELETE HPB235 designation and its related technical requirements;
- ADJUST the upper limit of S element content to 0.045%, and DELETE the
related technical requirements for residual elements in steel;
- DELETE 6.5 mm specification product and its related technical
requirements;
- ADD the requirement for bending per meter of straight bars;
- TIGHTEN weight deviation;
- ADD the measurement provisions when yield strength is not evident;
- ADD the provision that re-inspection is not permitted when weight deviation
is unacceptable;
- ADD the provision that protruding factory name and other surface markings
can be added on the surface of bars;
- DELETE Appendix A (normative appendix) “Method for determination of
total elongation of bars under the maximum force”.
This Part uses the redraft law to refer to ISO 6935-1.2007 “Steel for the
reinforcement of concrete - Part 1. Plain bars” for development. The degree of
consistency with ISO 6935-1.2007 is not equivalent.
Steel for the reinforcement of concrete -
Part 1. Hot rolled plain bars
1 Scope
This Part of GB/T 1499 specifies the terms and definitions, designation,
ordering content, dimensions, shape, weight and permissible deviation,
technical requirements, test methods, inspection rules, packaging, marking,
and quality certificate of hot rolled plain bars to be used as reinforcement in
concrete (hereafter known as bars for short).
This Part is applicable to hot rolled straight and coil plain bars to be used as
reinforcement in concrete.
This Part is not applicable to the recycled bars produced by rerolling of finished
steel.
