Pls who has the steel GB1499 1 2008 standard

GB Steel for Reinforced Concrete Part 1: Hot-Rolled Round Reinforcement" current standard, which stipulates the terms and definitions, classification, grade, order content, size, shape, weight and allowable deviation, technical requirements, test methods, inspection rules, packaging, marking and quality certificates of hot-rolled round steel bars for reinforced concrete; It is suitable for hot-rolled straight bars and coiled round steel bars for reinforced concrete. This section does not apply to recycled steel bars made from finished steel rolled again; Since the date of implementation, the wire rod part for construction in "GB T 701-1997 low-carbon steel hot-rolled round rod" and "GB 13013-1991 hot-rolled round steel bar for reinforced concrete" have been invalidated.

Compared with GB 13013-1991, the main changes are as follows: 3 2 eigenvalue definitions are added; Increases strength level by 300; Combined with GB T 701-1997, increase product specifications; Added Chapter 5 Ordering Content; Amendments to the terms "surface quality" and "measurement of weight deviation"; Modify and unify the steel bar grade, and unify the strength grade code R235 in GB 13013-1991 and Q235 in GB T 701-1997 to HPB235. There is a free version of the Standard Repository BZXXK**.

There is this standardization on the Internet, I took a look at it, and I think there is some information about this to send to you, I hope it can help you!

Standard number: GB

Standard name: Steel for reinforced concrete Part 1: Hot rolled round steel bar.

Standard Status: Active.

English title: steel for the reinforcement of concrete - part 1: hot rolled plain bars

Substitution: Replacement of the corresponding part of GB T 701-1997; gb 13013-1991

Date of implementation: 2008-9-1

Promulgating Departments:General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China.

Brief introduction: This part stipulates the terms and definitions, classification, grade, order content, size, shape, weight and allowable deviation, technical requirements, test methods, inspection rules, packaging, marking and quality certificates of hot-rolled round steel bars for reinforced concrete. This part is applicable to hot-rolled straight bars and coiled round steel bars for reinforced concrete.

This section does not apply to recycled steel bars made from finished steel rolled again; Since the date of implementation of this part, the wire rod part for construction in GB T701-1997 "Hot-rolled Circular Rods for Mild Steel" and GB13013-1991 "Hot-rolled Round Steel Bars for Reinforced Concrete" shall be invalidated.

Compared with GB13013-1991, the main changes in this section are as follows:

Add 3 2 eigenvalue definitions;

Increases strength level by 300;

Combined with GB T 701-1997, increase product specifications;

Added Chapter 5 Ordering Content;

Amendments to the terms "surface quality" and "measurement of weight deviation";

Modify and unify the steel bar grade, and unify the strength grade code R235 in GB 13013-1991 and Q235 in GB T 701-1997 to HPB235.

Up to now, steel for reinforced concrete Part 2: hot-rolled ribbed steel bars has not been implemented, and the current implementation standard is.

The validation work has been completed, but the reporting work has not yet been completed, mainly according to the requirements of the "Notice on the Integration and Streamlining of Mandatory Standards" (Guo Ban Fa 2016 No. 3) issued by the General Office of the People's Republic of China. The revision has undergone great changes in the judgment and inspection of the metallographic nuclear organization, and at the same time tightened the weight deviation and improved the strength grade, after the implementation of this standard will have a positive role in eliminating backward production capacity, promoting the reduction of steel use, and building a conservation-oriented society.

1. Introduction to the standard.

GB 1499-1998 "Hot-rolled ribbed steel bars for reinforced concrete" (PDF full text) was issued by the State Administration of Quality and Technical Supervision on October 16, 1998, and came into force on April 1, 1999.

II. Background of the compilation.

GB 1499-1998 "Hot-rolled Ribbed Steel Bars for Reinforced Concrete" is non-equivalent using ISO 6935-2:1991 "Steel for Reinforced Concrete Part 2: Ribbed Steel Reinforcement", which is based on the original standard GB 1499-91 "Hot-rolled Ribbed Steel Bars for Reinforced Concrete", combined with the specific conditions of production and use in China. Information Standards Research Institute of the Ministry of Metallurgy.

3. Scope of application.

The purpose of this standard is to stipulate the definition, classification, grade, size, shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality certificate of hot-rolled ribbed steel bars for reinforced concrete. Clever Tomb.

This standard applies to hot-rolled ribbed steel bars for reinforced concrete. This standard does not apply to recycled steel bars made from finished steel re-rolling.
