Usage and Applications of 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 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

Q:What is the length and size of thread steel?
Domestic sales of domestic thread steel, if the contract does not specify requirements, usually fixed length of 9m, 12m two length.
Q:How much does a futures screw do?
How much is one hand steel futures: the emphasis in the futures market is the margin system, which is one of the differences between the stock markets. The so-called margin system, if the margin is 10%, then you only use the actual price of 10% of the price can be traded.With the delivery day approaching, the margin will gradually increase.Margin = hand screw thread steel per ton steel price * * tonnage margin ratio, if the steel price is now 1900, steel is a hand of 10 tons, the hand margin is 1900 yuan / ton *10%=1900 yuan *10 tons.
Q:Are steel bars used more in high-rise buildings or steel?
To see what kind of structure, frame structure, screw steel is much more used, such as beam column, main reinforcement, partial stirrups, plate reinforcement.
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 strength than ordinary ribbed steel bars to be high, with spiral thread, tension nut after solid increase concrete prestressed (equivalent prestressed steel wire, steel wire type).
Q:What are the main use of threaded steel?
Steel is usually used for reinforced concrete, its role is to increase the friction fringe, the rebar and concrete secant integrally formed together, tic phenomenon can not occur in the role of external force, improve the strength of concrete.
Q:How heavy can a 25 mm thread steel bear?
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:What is the quality difference between round bar and screw 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:Do l 8, three grade steel have discs?
If small specifications or hot rolled straight line, the cost is high, not to say, production is still low, the general steel mills in order to produce the production of discoid small threads, and then according to the needs of the use of mechanical processing into a straight bar shape
Q:Thread steel 20*9 one is 2.001T. How many pieces of this one?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the 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 two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:High strength thread steel hrb400e 32 in diameter, is it special steel?
In addition to high-quality carbon structural steel, carbon tool steel and carbon spring steel, the rest are alloy steel, and alloy steel accounts for about 70% of the special steel.
