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:The 8 thread can replace the beam stirrups by steel
That's fine, but it's not necessary. It's more expensive. Of course, there's no substitute for steel bars on the site.
Q:Requirements for groove welding of grade 22mm round steel and manual arc welding
On the lathe, the car C9 chamfer (the car is sharp and difficult to weld, the car's chamfer is too small, the root is not welded).When welding, pull apart the gap of 2mm above the root clearance, the condition allows the edge to rotate while welding, otherwise it can only be welded in all positions.
Q:Will the theoretical weight of thread steel and round steel be the same?
The theoretical weight of threaded steel and round steel is the same. The middle part of the steel bar size ratio is small, the design time actually unit weight are the same, just screw steel crescent and transverse ribs prominent, resulting in heavy steel should be better than the illusion of formula is 0.00617 multiplied by the square of the diameter / m.
Q:The difference between galvanized round bar and galvanized flat steel?
Galvanized round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as 50, which means a round bar of 50 millimeters in diameter. Round steel is not the same as other steel bars. Round steel is round in shape and has no ribs and no ribs, which makes the bonding strength between round bar and concrete very small.
Q:45# what are the main rounds for?
High quality carbon structural steel can be used in many and many structural steels. It is widely used and can be used as long as it does not involve corrosion, or too high strength and toughness
Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
The tensile capacity of the anchor bolt is the tensile capacity of the round bar itself. The size is equal to the sectional area multiplied by the allowable stress (Q235B:140MPa, 16Mn, or, Q345:170MPA), that is, the allowable tensile load capacity at design time.
Q:Which is hard, round steel or screw steel?
If the diameter is the same, of course, the rebar is of great hardness.Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.
Q:Special steel bar steel products used to do what
But the red hardness difference of this kind of steel, that is, when the working temperature is greater than 250 degrees, the hardness and wear resistance of steel will decline rapidly, and lose their ability to work. In addition, carbon tool steels, such as those made of larger parts, are difficult to harden and easy to produce
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:How can stainless steel rounds occur? Is it a quality problem?
Cracks caused by surface folding, cracks and steel surface of 15 degrees to 75 degrees angle, about 1.5 ~ 3.5mm, tail vortex shape, slightly decarburization on both sides, decarburization layer 0.15 ~ 0.25mm, crack in the presence of oxide scales. Its macro shape is in the surface of the round steel along the rolling direction into a straight line or zigzag, continuous or intermittent appear in the partial or full length of steel. This shows that this is a folding process in the process of rolling steel. Main reasons of folding is finished before the workpiece with a handleonapot; secondly, in the process of rolling each pass from the handle, flash, serious scratch, damage, and roll ring groove wear etc., can make the product surface folding; in addition, such as the serious defect of blank, if cleaning may also be caused by improper finished folding. Therefore, the main measures to reduce or avoid folding appear: pass through reasonable design, accurate estimation of the spread, precisely adjust the position of roller groove, reduce or eliminate the finished product before rolling the handle, flash, scratches and other defects; the serious defects of the blank surface carefully cleaned.
