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 much does a futures screw do?
Suppose the present price of the steel thread is 2515 yuan, this is the price per ton, the thread steel is 10 tons per hand, the contract value is 25150 yuan, the margin ratio is about 8%, so it will cost 2012 yuan to do one hand thread steel.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Longitudinal tie rod. Longitudinal seam usually has longitudinal contraction joint and longitudinal construction joint two kinds, two kinds of longitudinal joints should be provided with tie rod. The bar shall be designed with the length of the threaded steel to ensure the bond between it and the concrete, and the diameter and spacing of the tie rod shall also be guaranteed. Thus, the tie rod can not provide enough tensile force, and when the concrete faceplate is contracted, the longitudinal joint is pulled apart to form a crack.
Q:How much is the minus difference per ton of thread steel?
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. The grade of thread steel is composed of the minimum value of the yield point of HRB and brand.
Q:Cast-in-place with 10 mm reinforcement, a good layer or 8 mm double layer? Why?
In general, 8 of the bilayer is better than 10 of the single layer.(1) the reinforcement of cast-in-place slab shall be designed according to the principle of fine reinforcement.(2) the cast-in-place slab shall be controlled with a minimum reinforcement ratio greater than 0.25%.
Q:Grade 1, grade three, grade two, steel, wire rod, round bar
Wire is a wire, usually refers to the use of "high speed non-twist wire rod rolling mill, ordinary common low carbon steel, hot-rolled wire torsion free cooling (ZBH4403-88) and the high quality carbon steel, hot-rolled wire rod without torsion cold control (ZBH44002-88).
Q:What does thread steel have to do with scrap steel?
There is some dealers do not scale steel processing business, because of the non standard long thread steel ruler to teach cheap price, dealers can not only earn processing fees can also earn the price difference, because the processed steel ruler with non positive material standard screw thread steel is the same price, reasonable use of processing small not waste head down more than the standard, but the boss is also doing scrap. Answered so much hope to adopt.
Q:Difference between round bar and threaded steel in use
The rebar is much higher than the ordinary, and the low carbon steel rounds are much higher. The heat treated steel is much stronger than the low carbon round steel, nearly twice or even higher.
Q:What is thread steel for?
The difference between three grade steel and two grade steel can be divided into the following aspects:1, different grades of steel (chemical composition is different). HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;2, strength is different, HRB335 grade steel tensile and compressive design strength is 300MPa, HRB400 grade steel tensile and compressive design strength is 360MPa.3, because of the chemical composition of steel and the ultimate strength of different, so in toughness, cold bending, fatigue and other properties are also different.
Q:How to judge the quality of thread steel?
Sampling sample. Do tensile, bending, and impact tests.
Q:Are rebar bars = rebar?
Rebar is only one of the reinforcing bars, and the reinforcing bars used in the construction site are distinguished from the appearance. They are mainly round steel (round steel bars) and plain steel (the appearance has lines, and the steel bars are divided into two kinds: thread and crescent).
