Specifications of Hot Rolled Steel Rebar:

The production process of Steel Rebar

1-Waling beam furnace  2-Roughing rolling group  3-Intermediate rolling train

4-Finishing rolling group  5-Water-cooling device  6-Walking beam cooler

7-Finishing equipment(including the cold scale shear,short feet collection system,

    automatic counting device,bundling machine, collect bench)

Usage and Applications of Hot Rolled Steel Rebar:

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 Hot Rolled Steel Rebar:

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 terms: TT payment in advance or Irrevocable LC at sight.

Trade terms :FOB, CFR, CIF

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

Note:

1. Our products are produced according to national standard (GB), if not, supply according to national standards (GB) or agreement as customer required.

2. Other Grade and Standard Deformed Steel Bar we can supply:

Q:What is the specific concept of thread steel through water and what is the difference?
Most of the thread steel is subjected to self - tempering after water cooling, and the tempered bainite is obtained. The advantage is that the strength will be better; the disadvantage is that after rolling through water, the surface oxide film of steel is destroyed, rust is sure
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?.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Dowel arm for transverse construction joint. The transverse construction dowel bar is applied with a light circle and half coated with asphalt, allowing sliding. In practical application, the construction units are convenient for drawing, often use thread steel, and do not apply asphalt. The concrete pouring time on both sides of the construction joint is different, the contraction during the condensation process is not synchronous, and the dowel bar can not be stretched and formed a weak link. Cracks occur at this weak point when concrete slabs contract under loads or natural factors.
Q:What is the carbon content of thread steel?
The carbon content in the threaded steel is best about 1%, so that it can not only ensure the strength and hardness of the thread steel, but also ensure its plasticity and toughness.
Q:What is the difference between the material of steel thread and its use?
Main uses: widely used in housing, bridges, roads and other civil engineering construction.Main origin: the manufacturer of thread steel is mainly distributed in North China and Northeast China
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
Now Tianjin Tiantai into 12 of the price is 3900 yuan a ton, 16 tons of steel a price is 3850 yuan. 12 of thread steel is 50 yuan more expensive than 16 thread steel.
Q:Is the shear wall concealed column stirrup steel or round steel? What are you asking for?
Specify the construction drawing is HPB300 is hot rolled round bar, that is HRB335, HRB400 is the hot rolled ribbed bar. Don't call thread steel, this name has long been abandoned. Simple, light marked wall column reinforcement detail construction drawing on the diameter and spacing is not encrypted, what non encrypted area, like the dense spacing.
Q:What does "4esg25" mean on thread steel?
4esg25 these are the basic information of reinforcement, equivalent to the identity card information. Represents grade four steel (HRB500), and ESG represents the modulus of elasticity of the reinforcement in the reinforcement; then the nominal diameter is 25.
Q:The effect of adding alum on thread steel
Vanadium can remarkably improve the weldability of ordinary low carbon low alloy steel. Vanadium is an excellent deoxidizer for steel. 0.5% of the vanadium in the steel can refine the grain and improve the strength and toughness. The carbides formed by vanadium and carbon can improve hydrogen corrosion resistance under high temperature and high pressure.
Q:Why does the steel thread have longitudinal ribs?
The main function of the longitudinal ribs is the force to improve the performance of the transverse ribs, the stress of support surface transverse rib in the longitudinal direction, reducing flange stress concentration, so as to improve the mechanical strength of the reinforced rib, deformation of bond between concrete and steel reinforced concrete, the collaborative work and better.The effect of the longitudinal ribs is indirect, which improves the mechanical properties of the transverse ribs and indirectly enhances the bond with the concrete.
