Product Description
Threaded steel coils are rebars that are coiled together like wire rods, and are also a kind of steel for construction.Class II, Class III, and Class IV rebars are all old names before, and the new standards are called HRB400 and HRB500 respectively, which are classified according to the strength level (yield point/tensile strength), and the numbers behind are the strength values , the unit is Mpa. H, R, and B are the English initials of the three words Hotrolled, Ribbed, and Bars, respectively. Finished threaded steel bar refers to the threaded steel bar for prestressed concrete, which belongs to the steel for construction. As the name suggests, coiled snails are rebars that are coiled together like wires, and they are also steel for construction.

Commonly used rebar specifications are as follows:
GB700-88 (carbon structural steel);
GB/T 2101-89 (general regulations on section steel acceptance, packaging, marking and quality certificate);
GB1499-91 (rebar for concrete);
JIS G3112-87 (98) (bar steel for reinforced concrete);
JISG3191-66 (94) (shape, size, weight and tolerance of hot-rolled steel bars and coiled steel bars);
BS4449-97 (hot-rolled steel bars for concrete structures).
Detailed Photos
1. Specifications: The specification requirements of rebar should be listed in the import and export trade contract. Generally, it should include the standard grade (category code), the nominal diameter, nominal weight (mass) of the steel bar, the specified length, and the tolerance value of the above indicators.
For 8, 10, 12, 16, 20, 4 national standards, the rebar series with a nominal diameter of 0mm is recommended. The supply length is divided into two types: fixed length and double length. The selection range of the length of the rebar exported from my country is 6-12m, and the selection range of the length of the rebar produced in Japan is 3.5-10m.
2. Appearance quality:
Allowable value of external dimension deviation. The requirements for the bending degree of rebar and the geometric shape of the steel bar are stipulated in the relevant standards. As stipulated in the national standard, the bending degree of straight steel bars is not more than 6mm/m, and the total bending degree is not more than 0.6% of the total length of the steel bars.
surface quality. Relevant standards stipulate the surface quality of rebar, which requires that the ends should be cut straight, and the surface should not have cracks, scars and folds, and there should be no harmful defects in use.
Quality Testing
1. Performance indicators: The inspection items for evaluating the mechanical properties of rebar include tensile test (tensile strength, yield strength, elongation), bending test (primary bending and reverse bending).
2. Inspection method:
Tensile test method: Commonly used standard inspection methods include GB/T228-87, JISZ2201, JI SZ2241, ASTMA370, ГОСТ1497, BS18, etc.; Bending test method: Commonly used standard inspection methods include GB/T232- 88. JISZ2248, ASTME290, ГОСТ14019, etc.
