Usage and Applications of HRB400 Deformed Steel Bar:

Deformed bar is widely used in buildings, bridges, roads and other engineering construction. Big to highways, railways, bridges, culverts, tunnels, public facilities such as flood control, dam, small to housing construction, beam, column, wall and the foundation of the plate, deformed bar is an integral structure material. With the development of world economy  and the vigorous development of infrastructure construction, real estate, the demand for deformed bar will be larger and larger..

Packaging & Delivery of HRB400 Deformed Steel Bar:

Packaging Detail: products are packed in bundle and then shipped by container or bulk vessel, deformed bar is usually naked strapping delivery, when storing, please pay attention to moisture proof. The performance of rust will produce adverse effect.

Each bundle weight: 2-3MT, or as required

Payment term: TT or L/C

Delivery Detail: within 45 days after received advanced payment or LC.

Label: to be specified by customer, generally, each bundle has 1-2 labels

Trade terms: FOB, CFR, CIF

Q:How heavy can a 25 mm thread steel bear?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words.
Q:How to calculate the theory of steel thread?
Thread: a spirally curved, continuous raised part with a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
Q:What is hot rolled coil? Hot rolled coil relative to thread steel and other steel, is not considered a higher point?
Cold rolled strip is produced by pickling, rolling, annealing, finishing and oiling.Which requirements are higher for strip and thread steel, and because of the different products, the individual considers that there is no comparability.
Q:How is thread steel made?
Rebar is a ribbed steel bar, also known as ribbed steel, usually with 2 longitudinal ribs and transverse ribs uniformly distributed along the length. The transverse rib shape is helical, herringbone, crescent 3. Expressed in millimeters of nominal diameter. Nominal diameter of round steel bars of equal diameter equal to the cross section of ribbed bars. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40 mm. Ribbed steel bars are mainly subjected to tensile stress in concrete. Because of the function of rib and the greater bonding ability of concrete, ribbed steel bar can bear the effect of external force better. Ribbed steel bars are widely used in a variety of building structures, especially large, heavy, light, thin-walled and high-rise structures.
Q:Grade 1, grade three, grade two, steel, wire rod, round bar
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:Thread steel 20*9 one is 2.001T. How many pieces of this one?
The weight of the thread steel = diameter * diameter *0.00617=20*20*0.00617=22KG, and then the total quality of this piece in the weight of a single thread steel, you can clearly get the number of roots.
Q:The difference between wire and thread steel, wire and thread steel difference knowledge
In general, the main differences between the two:1) their yield strength characteristic value is 235300 of wire rod and 335400500. of thread steel2) specifications, diameter, wire specifications 6 or 6.5, 8, 10, 12mm; thread steel specifications 12 - 50mm are.3) common wire line and the line, is a disc (weighing) for sale; steel market at present is selling bar (a rebar), three steel, four steel, by bundling or by root (foot) to sell.
Q:What is the difference between grade two and three grade steel?
In fact, from the definition, we can only see that two grade rebar and three grade thread steel is only different in material, one is HRB335, and the other is hrb400.
Q:What's the difference between round bar and screw steel? Which one is cheaper on the market at present?
Round steel and thread steel are mainly made of different materials and purposes, so prices are different, and they need to be chosen according to actual needs.
Q:Cold drawn steel wire is a round bar or thread steel in Construction Engineering
Cold drawn steel wire belongs to round bar in building engineering, and it is thread steel after coining. But the material of steel is not good. Who knows what material he made?.
