Usage and Applications of Wire Rod Q235:

After hot-rolled the products shaped into coil and delivery as finished product, including round, square, rectangular, hexagonal and so on. Since most of the products are round, it is generally called wire rod. Carbon steel wire rod is widely used in construction and manufacturing. Carbon steel wire rod is mainly used for reinforcement of reinforced concrete and welded structure or reprocessed (roberts , nail, etc.) materials, especially used to produce wire drawing, welding electrode, nails,  spring, electronic,  precise machinery parts  and so on.

 

Packaging & Delivery of Wire Rod Q235:

Packaging Detail: products are packed in coil and then shipped by container or bulk vessel

Each coil weight: 2-3MT

Delivery Detail: within 45 days after received deposit or LC.

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

Trade terms: FOB, CFR, CIF

Q:Why is the round bar bent?
In fact, the stress and deformation complex around reinforced concrete, bond stress varies with grip length of the rebar so bond strength with steel type, shape and position of the embedded in concrete, different direction and change, is also related to concrete strength, concrete compressive strength the higher the strength, the bond strength is generally determined by R=P/3.14dL. P for pullout force, D, rebar diameter, L, steel embedment length.
Q:How many grades of steel are round steel?
There are many kinds of steel. They can be divided into three categories: non alloy steel, low alloy steel and alloy steel by chemical composition. Ordinary steels are mostly unalloyed steels. Their quality is divided according to the impurities in the steel, namely ordinary quality carbon steel, high quality carbon steel and special quality carbon steel three kinds. Not by category.
Q:What is the difference between a circle and round steel continuous casting
The first two density is not the same, the round billet continuous casting billet is molten steel into round billet crystallizer, after two cold water cooling, solidification formation, density is small; bar is formed by the billet or round billet rolled steel products, good density, better mechanical properties than the same size of billet. Second, round billet is the raw material for steel rolling, and the bar is the final product sold as steel.
Q:4145H round steel is equivalent to the domestic brand?
4145H rounds are used in oil drilling tools and are often replaced by 42CrMo in the industry.
Q:Are the bolts for the round bar or round steel?
If in some large-scale concrete component under the condition of some units to prevent run mode is used, the bar, the bar is the best quality, and the tensile strength is great, because the price advantage is not, it is generally not recommended to use the bar as a pull screw.
Q:The problem of dowel bars on concrete pavements?
The dowel bar is arranged according to the transverse contraction joint and expansion joint set, meaning that a transverse contraction joint and expansion joint place dowels, are not plate must be set. In general, each 200m set a expansion joint, or other road intersection, and bridge connecting point must be set up.
Q:12mm Round steel, the material is Q235, the maximum weight can bear?
The cross sectional area of 12mm steel is 3.14*36=113.04 mm, the maximum can bear much weight: 113.04*235=26564.40 cattle, is about 26.56440 kn.
Q:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
The main differences are in mechanical properties. I don't know very well how to make round steel, I can't compare it. Forged round steel is expected to be used in the processing of some special performance requirements.
Q:What is the difference between cast iron and round steel?
One is an iron, steel, concrete, and is about 2.11 carbon steel, above is iron; cast iron consists of gray iron and ductile iron, vermicular iron and steel, the more
Q:Can steel bars be replaced by large screws in the concrete floor?
In theory, how big a round steel will have to replace the large thread steel, and if it is cast, then still better to use thread steel, screw steel tensile resistance than round steel by strong
