China High quality Waterproof Coating – factory Outlet 10mm12mm 16mm high tensile deformed steel bar – Future Metal
China High quality Waterproof Coating – factory Outlet 10mm12mm 16mm high tensile deformed steel bar – Future Metal Detail:
Hot-rolled ribbed steel bars are divided into three grades: grade II HRB335 (old grade 20MnSi), grade III HRB400 (old grade 20MnSiV, 20MnSiNb, 20Mnti) and grade IV HRB500.
Rebar is a ribbed steel bar on the surface, also known as ribbed steel bar, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shape of the transverse rib is spiral, herringbone and crescent shape.
Expressed in millimeters of nominal diameter. The nominal diameter of a ribbed bar corresponds to the nominal diameter of a round bar of equal cross-section. The nominal diameter of the rebar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm.
Application of deformed bar
Ribbed steel bars are mainly subjected to tensile stress in concrete. Due to the action of ribs, ribbed steel bars have greater bonding ability with concrete, so they can better withstand the action of external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.

Performance test
1. Mechanical properties
(1) Performance indicators: The inspection items for evaluating the mechanical properties of rebar include tensile test (tensile strength, yield strength, elongation), bending test (one-time bending and reverse bending).
(2) Inspection method:
① Tensile test method: Commonly used standard inspection methods include GB/T228.1-2010, JISZ2201, JI SZ2241, ASTMA370, ГОСТ1497, BS18, etc.;
② Bending test method: Commonly used standard inspection methods include GB /T232-88, YB/T5126-2003, JISZ2248, ASTME290, ГОСТ1401 9, etc.
(3) Bending performance
After bending 180 degrees according to the specified bending center diameter, the surface of the bending part of the steel bar shall not have cracks.
(4) Reverse bending performance
According to the requirements of the purchaser, the steel bar can be tested for reverse bending performance.
The diameter of the bending center of the reverse bending test is correspondingly increased by one steel bar diameter than that of the bending test. Bend 90 degrees in the forward direction first, then 20 degrees in the reverse direction. After the reverse bending test, the surface of the bending part of the steel bar shall not have cracks.
2. Surface quality
There shall be no cracks, scars and folds on the surface of the rebar.
Bumps are allowed on the rebar surface.
Types of steel deformed bar
Rebar is produced by small rolling mills. The main types of small rolling mills are: continuous, semi-continuous and row. Most of the new and in-use small rolling mills in the world are fully continuous.
Popular rebar mills are general-purpose high-speed rolling rebar mills and 4-slice high-production rebar mills.
The product specifications are generally ф10-40mm, and there are also ф6-32mm or ф12-50mm.
The steel grades produced are low, medium and high carbon steel and low alloy steel that are widely demanded by the market; the maximum rolling speed is 18m/s.
production process of deformed bar is as follows:
Walking furnace → roughing mill → intermediate rolling mill → finishing mill → water cooling device → cooling bed → cold shearing → automatic counting device → baler → unloading stand.
Weight calculation formula: outer diameter Х outer diameter Х0.00617=kg/m
