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:4E DG 164 is a steel grade 3 steel, DG steel, E is what mean
E is the mark of the steel band seismic! Commonly known as: with E steel, or earthquake resistant steel!
Q:What grade of reinforcement is used for cast-in-place floorslab?
Compared with the floor slab, the cast-in-place concrete can strengthen the integrity and the seismic resistance of the building, and has greater bearing capacity. At the same time, in insulation, sound insulation, waterproof and other aspects also have certain advantages.
Q:What specifications should be used for the three - step steel electroslag pressure welding electrode?
Three - step steel electroslag pressure welding electrode with 3mm diameter wire can be.
Q:What is the difference between the material of steel thread and its use?
The grade of thread steel is composed of the minimum value of the yield point of HRB and brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into HRB335 (old No. 20MnSi), HRB400 (20MnSiV, 20MnSiNb, veteran, 20Mnti), HRB500 three brands.
Q:16 meters of thread steel, how many meters?
Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:Are thread steels of coarse steel?
Thread steel does not belong to coarse steel, rough is shaped steel, fine is wire.
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:14 screw steel 1 meters multiple?
Classified according to geometric shapes, according to the cross section of the rib section and the spacing of the ribs for classification or classification, such as the British Standard (BS4449), the thread steel is divided into type I, type ii. This classification mainly reflects the tightening performance of the threaded steel.
Q:Is cold-rolled ribbed steel bar thread steel?
I haven't heard of cold-rolled steel. Cold rolling is called thin plate
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).
