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: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:JL32 is the finish thread heavy bar 32? What's the difference between normal and ordinary? What does the front JL32 mean?
Finishing rolling rebar diameter of JL32-- 32mm, 32 - screw steel hot rolled ribbed steel bars, the difference between the two: 1, ribbed bar is injected directly into the concrete, increase of steel concrete.
Q:Why do stirrups have thread stirrups and round bars? When are they used?
Oh, the main reason is the force, not only for steel rebar, general structure of round diameter is less than or equal to 10, 12 and above with rebar (hot-rolled ribbed bar)
Q:12 how much is one ton of thread steel?
12 thread steel one meter weight: 0.888kg
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
12 of the screw steel, rice weight is 0.89kg/m, 16 of the screw steel, rice weight is 1.57kg/m, with 12 of the thread steel instead of 16 of the screw steel, to the same proportion, that in dosage will be more.
Q:What are the marking of the steel bars on the mills? Which factory is the 2LG16 thread?
2LG16 thread manufacturer is the Laiwu iron and steel works, referred to as "Laiwu Steel", the letter "LG", indicating that the steel produced by the diameter of 16 of the two grade thread steel.
Q:What is the difference between three - grade steel and two - grade steel?
Therefore, in the future, the three grade rebar will be widely used, in addition, anti seismic (with E mark) thread steel will also be widely used in our daily life.
Q:What is the quality difference between round bar and screw steel?
Different grades of steel (different chemical composition). Round steel (HPB235) is carbon steel, steel is Q235; thread steel is low alloy steel; HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;
Q:What's the difference between primary and two grade steel and three grade steel?
There are two levels of steel rebar, three steel, four steel grade difference, no grade steel, there are a lot of customers to wire (round) mistakenly called a steel. At present, China is gradually out of grade two steel, four steel grade two steel grade HRB335, three grade steel grade HRB400, four grade of steel wire is HRB500, (Pan Yuan) new material grades are HPB195, HPB235, HPB300, old wire material grades corresponding is Q195, Q235.
Q:Why is the threaded steel thread?
The difference between round bar and round bar is that the surface has longitudinal ribs and transverse ribs, usually with two longitudinal ribs and transverse ribs uniformly distributed along the length direction. The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required.
