rebar steel wholesalers in Asia

Rebar or steel reinforcement used in concrete to compensate for its low tensile strength (concrete). The steel used for this purpose in reinforced concrete structures is in the form of wire or rebar, and steel is called rebar. Of course, in certain cases, structural steel such as “stud”, “can” or cans are also used to reinforce concrete. Our product group is one of the rebar steel wholesalers in Asia, which produces and markets this product with the highest quality.

rebar steel specifications

In different countries, rebar steels are produced with different standards, and in each standard there is a specific classification related to the mechanical properties of steels. In Iran, most of the rebar steels produced by the Isfahan Steel Plant comply with the Russian standard. Steel produced in Iran (according to the Russian standard) is divided into three groups: type A-1 steel, type A-2 steel and type A-33 steel.

    A-1 steel is of smooth type and its yield strength and tensile strength (rupture stress) are 2400 and 3600 kg / cm2, respectively.

    A-2 is a ribbed steel with a yield strength of 3400 and a tensile strength of 5000 kg / cm2.

    A-3 steel is also ribbed with a yield strength of 4,000 and a tensile strength of 6,000 kg / cm2.

Manufacturers also differ in terms of the diameter of the rebars. In the Russian system used in Isfahan steel mills, rebars up to 40 mm in diameter are made.

Rebar A1 with a current stress of 2300 kg / cm2 and a rupture stress of 3800 kg / cm2 and a relative plastic deformation (at the time of rupture) of 25% is known as soft rebar and is mostly smooth and without tread. rebar material is suitable for forging, deformation and welding operations on it. . Generally known as a ductile rebar.

The standard rebar standard in the market is A2 and A3, which differ in their tensile and tensile strength. Currently, many of the market demands are A3 rebar due to lack of sufficient knowledge, but depending on the intended application, it can also be A2. In many cases and special sizes, A2 rebar may be the best choice.

 The sizes of rebars available in the market are between 5.5 to 40 mm. Of course, higher sizes are also produced and supplied depending on the customer’s needs and requests. The best choice for sizes 8 to 12 is A2 rebar because it is more flexible and is often used for bending and bending. But for sizes 12 and above, A3 rebar is purchased. But in general, according to the needs of the buyer and the accountant and designer of the project, the type of rebar and its strength is determined.

rebar steel wholesalers at cheap price

Another category of steel rebar is based on their diameter because each product is produced in different sizes and each is intended for a specific application. The diameter of the rebars produced in the domestic market of Iran is finally 40 mm. Head welding or forging is used for welding and connections of this category of steel products. In this method, the applied pressure is accompanied by the heating of oxygen gas. That is why they offer rebar steel wholesalers at cheap price, which are also of good quality.
