Rebar sizes of different standards as we know different countries have their own way to measure and record the reinforcing bar. Reported by the masonry standards joint committee 2002. Dh of bars with standard hooks are based on 22 tests reported by marques and jirsa 1975 which used neither highstrength steel nhighor strength concrete.

Astm s steel standards are instrumental in classifying evaluating and specifying the material chemical mechanical and metallurgical properties of the different types of steels which are primarily used in the production of mechanical components industrial parts and construction elements as well as other accessories related to them. To adequately transfer stresses from one. Standard specification for deformed and plain billet steel bars for concrete reinforcement astm a615 a615m 00. Astm international inc 2001.

Reinforcing steel splices standard hooks strength design working stress splices and development length minimum development lengths are necessary to adequately transfer stresses between reinforcement and the grout or mor tar in which it is embedded. This card is in inch pound in lb units. Many drawings refer to standard hooks and show hooked bars in specific areas for top and bottom reinforcing. Standard specification for low alloy steel deformed and plain bars for concrete reinforcement astm a706 a706m 01.

Pocket sized card is a handy reference showing standard bar sizes diameters areas and weights along with hook details. The app provides standard rebar specifications including sizes diameters areas and weights along with 90 135 and 180 degree. To meet the needs of our customers we display some rebar sizes charts so that it is easy to choose the most suitable rebar you wanted. Cu r rent standard s a s s u r e that the latest technology is being incorpora t e d into a project and the availability of materials is more c e r tain.

Also shows minimum yield and minimum tensile requirements per astm. 90 degree hooks those that have a 12 bar diameter extension on the hook leg pin to end 180 degree hooks and stirrup and tie hooks those that have a 6 to 12 bar diameter. Howe ve r to maximize the benefits of standard i z a t i o n it is essential that up to date materials standards be re f e r enced in the contract documents. Reinforcing steel for these tests had yield strengths 64 and 68 ksi and of the compressive strengths of the concrete were between 3 750 and 5 100 psi.
