Grade 75 Grade 80 Deformed Rebar Options: Though A rebar by definition is comprised simply of deformed, plain carbon steel, it can be enhanced with epoxy coatings or other strength and durability-enhancing treatments if project requirements demand it. At Harris Supply Solutions, we pride ourselves on offering customers the ability to customize their rebar products to precision specifications, so if you need A rebar with augmented performance specifications, we are happy to fill your order. Usage of A Rebar A rebar increases the tensile strength of concrete and can be used for both primary and secondary reinforcement. It helps absorb stress and weight and facilitates the more even distribution of the tension caused by the expansion and contraction of concrete when it is exposed to heat and cold, respectively. If you have any questions about the suitability of A rebar for your intended application, or if you would like to submit a custom order, obtain a price quote, or discuss your specific needs, please contact a member of our customer service team. Harris Supply Solutions is one of the largest suppliers of rebar and steel mesh in the United States, and our extensive production and distribution network enables us to fill your order quickly, for a highly competitive price.

This specification has been approved,for use by agencies of the Department of Defense and for listing in the DoD Index of Specifications and Standards. Scope , 1. The standard sizes and dimensions of deformed bars and their number designations shall be those listed in Table 1. For bending properties test provisions of the nearest smaller nominal diameter deformed bar size shall apply.

Note 1—The values stated in inch-pound units are to be regarded as the standard. Applicable Documents 2. Ordering Information 3. Current edition approved July 27, Originally published as A Material and Manufacture 4.

Requirements for Deformations 5. Where the line of deformations forms an included angle with the axis of the bar of from 45 to 70 deg inclusive, the deformations shall alternately reverse in direction on each side, or those on one side shall be reversed in direction from those on the opposite side. The nominal perimeter of the bar shall be 3.

Measurements of Deformations 6. A measured length of the bar specimen shall be considered the distance from a point on a deformation to a corresponding point on any other deformation on the same side of the bar. Spacing measurements shall not be made over a bar area containing bar marking symbols involving letters or numbers. No rejection may be made on the basis of measurements if fewer than ten adjacent deformations on each side of the bar are measured.

Note 3—A lot is defined as all the bars of one bar number and pattern of deformation contained in an individual shipping release or shipping order. Tensile Requirements 7. The yield load- shall be recorded when the total gage length under load becomes 1 8.

Bending Requirements 8. The requirements for degree of bending and sizes of pins are prescribed in Table 3. Test Specimens ; ,..

Number of Tests Reinforcing bars are evaluated on the basis of nominal weights. In no case shall overweight of any bar be the cause for rejection. Finish Marking Packaging The applicable levels shall be as specified in the contract. Inspection All tests and inspection shall be made at the place of manufacture prior to shipment unless otherwise specified, and shall be so conducted as not to interfere unnecessarily with the operation of the works.

ASTM A616: Rail-Steel Deformed and Plain Bars for Concrete Reinforcement

Meran Several people in Europe and North America developed reinforced concrete in the s. Views Read Edit View history. The metal is partially straightened, bundled and sold. Turner voiced strong objections to this system as it could cause catastrophic failure to concrete structures. However, for small or custom work a tool known as a Hickey, or hand rebar bender, is sufficient. If aa were not so, it would cause problems through additional longitudinal and perpendicular stresses at temperatures different from the temperature of the setting. He invented twisted iron rebar, which he initially thought of while designing self-supporting sidewalks for the Masonic Hall in Stockton, California.
