New updates on Saudi standards of steel bars and steel sheet Eng. Sultan AlSoghaier SASO

2 The contents of presentation: - steel bars overview. - steel sheet overview.

3 Introduction : -SASO gives it’s interesting in issuing a national standard for steel bars. -the second standard was issued by SASO it was about the steel bars, SASO 2:1979 "steel Bars for concrete reinforcement". -The standard was updating at 1992 by technical committee. -SASO has adopted a number of other foreign steel reinforcement standards such as ASTM standards ASTM A706,ASTM A615 -SASO has adopted a number of international references such as ISO ,ISO , ISO SASO noticed recently directed a number of national factories to manufacture according to standards other than SASO standard such as the ASTM 615 and British standards for consulting offices and large companies which Requests that and it use large amounts of it in their projects.

SASO received many inquiries: * What is the mandatory standard for steel bars ? * When you receive a consignment of steel bars and confirmed to the ASTM and international standards, is it allowed to enter the Kingdom of Saudi Arabia ? * Why is there more than one standard? * Complains about standard of steel bars ? 4

SASO efforts in cooperation with the Ministry of Commerce and Industry 1- SASO made workshop on September 2014 about standards and operations of reinforcing steel manufacturing, and it’s resulted in the recommendation to adopt the ASTM standards ASTM A706, ASTM A615 with the development of the necessary adjustments to be meet the national requirements. 2- The inspection of a number of national factories : SASO participated in collaboration with the Ministry of Commerce and Industry to inspect a number of national factories to check the extent of their commitment to the Saudi standard and have been shut down some of it for failing to achieve any of the approved standards, and damaging their products which are not conforming to the approved standards, till they can carry out corrective actions and to provide a system monitors the quality of their production process. 3- Conducting a survey on local markets : SASO participated in collaboration with the Ministry of Commerce and Industry conducted a survey on local markets and withdrawal samples for reinforcing steel to check their conformity to the Saudi standard specifications related to the product. 4- The most prominent irregularities that have been observed : Failure to achieve the minimum yield stress, shortage of diameters, shortage of longitudinal meter weight, failure to achieve the dimensions of the ribs, failure in tensile increase carbon ratio and C eq test, failed to test the bending and re-bending, failure in the virtual screening. 5

SASO technical committee of Steel Products According to the mechanism of action of system technical committees to prepare Saudi standards and technical regulations : members are: * Academy bodies * Industrial bodies * Government bodies * SASO 6

Some key findings in the technical committee SASO added national deviation which is required to adopt ASTM standards and modification annex to SASO ASTM A706, SASO ASTM A615, such as the use of international units and add some sizes that are not available the ASTM standards. * Agreeing on the debate about carbon content to have no limit for it as per SASO ASTM A615 7
