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:Cold drawn steel wire is a round bar or thread steel in Construction Engineering
Cold drawn steel wire should be the same as round steel and thread steel! Their forming process and the meaning of the place used are different, and the quota is also different, cold drawn steel wire is cold drawn steel wire, strictly speaking, there is no mix together.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Fine grain hot-rolled steel grades in the hot rolled ribbed bar with English abbreviation "fine" English (Fine) first letter. Such as: HRBF335, HRBF400, HRBF500. There are higher requirements for the seismic structure, the applicable brand is: after the existing brand plus E (such as: HRB400E, HRBF400E).
Q:Thread steel generally used for more?
Mainly used for reinforcement of reinforced concrete and prestressed concrete structures. It is one of the most widely used kinds of steel in civil engineering.
Q:What is the difference between three - grade steel and other grades?
Three rebar is the new standard name for HRB400 steel, three steel for the old, as a kind of hot rolled ribbed bar. In construction, three - grade rebar is called the past.
Q:What is the diameter of the cross section of the threaded steel?
There are many ways to measure diameter. Different methods are adopted according to different precision requirements,The simplest method is to use the scale directly, and the longest line through the section is the diameter. This method has the lowest precision
Q:What is the difference between rebar bolts and steel bars?
This question can only be answered: "material should not be compared to components.". Insist on saying the difference, one is the material, and the other is the component.You may ask the difference between soil nail and anchor bar, but the topic is not. I shall be glad to answer another question!
Q:Does the grade three thread steel with "E" have the same information price as the ordinary three grade thread steel? Is there a big difference?
As far as I know, the price of information may not be divided into "E" and "E", but there are mandatory requirements on the standard. It is estimated that the price will not be much different.
Q:What's the difference between rebar and thread steel?
Physical and mechanical properties are different. Because of the different chemical composition and strength of reinforcing steel, they are different in physical and mechanical properties. The cold bending property of steel is good, can make the hook 180, screw steel can only make straight hook 90 degrees; steel weldability is good, with ordinary carbon steel electrode can be used to low alloy electrode; anti fatigue performance and toughness in steel bar is good.
Q:Is thread steel rod or wire?
Bars: straight steel bars of circular diameter, six angles, square or other special-shaped shapes. In stainless steel, the majority of bars generally refer to round steel.Wire rod refers to the hot-rolled steel bar of 5-22mm diameter or the special-shaped steel of this section. As a result of wire rod delivery, it is also known as wire rod.
Q:The effect of adding alum on thread steel
Vanadium has many excellent physical and chemical properties, so vanadium has a wide range of uses. Most of the initial vanadium was applied to steel. By refining the microstructure and grain of steel, the grain coarsening temperature was increased, thus increasing the strength, toughness and wear resistance of steel. Later, people gradually discovered the outstanding improvement of vanadium in titanium alloys, and applied it to the aerospace field, which made the aerospace industry made a breakthrough progress. With the rapid development of science and technology, the demand for new materials is increasing. Vanadium is used more and more widely in the field of non iron and steel. Its range includes aerospace, chemistry, batteries, pigments, glass, optics, medicine and many other fields.
