Round steel refers to the solid section for circular strip steel.Its specifications expressed as a number of mm in diameter, such as ""50"" indicates that the diameter of 50 mm round steel.Round steel hot rolling, forging and cold drawn three kinds.The specifications of the hot rolled round steel of 5.5 to 250 mm.5.5-25 mm small round steel are mostly with straight into bundles of supplies, commonly used for reinforcing steel bar, bolt, and various mechanical parts;More than 25 mm round steel,mainly used in the manufacture of mechanical parts and seamless steel tube billet.

Carbon steel according to the chemical composition (i.e., with carbon content) can be divided into low carbon steel, medium carbon steel and high carbon steel.According to the quality of the steel can be divided into ordinary carbon steel and high quality carbon steel.According to the purposes and can be divided into carbon structural steel, carbon tool steel.

The difference between the round steel and other steel: 1 appearance is not the same, round steel exterior circle of light, no lines without ribs, and other steel surface appearance has a groove or a rib, thus causing the cohesive force of small round steel and concrete, and the other the cohesive force of steel bar and reinforced concrete.2 ingredients are different, round steel (level 1) steel belong to the normal low carbon steel, more than other reinforcement for alloy steel.Three different intensity, low intensity of round steel and other steel high strength namely round steel have larger deformation before is pulled, and reinforced by other tensile deformation is much smaller.

Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
The general situation is not possible, but sometimes as stirrup time, and has little effect on the structure, if 12 reinforced with missing a few, but not on the main force position is possible, sometimes supervision is not allowed.
Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
8 there is no regular reinforced steel bars are straight, round, there is straight, as you said 9 M 1, but that's rolling, if their home, can also, engineering is prohibited
Q:Difference between forging and round steel
The advantages of a casting include an extensible length, a contracted cross section, a contracted length, an extended cross section, a variable length, and a variable cross section. The types of casting are free forging / hand forging, hot die forging / precision forging, top forging, roll forging and die forging.Forgings are not limited to round shapes.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.Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:How to determine the welding seam height of steel plate and steel bar?
How to determine the welding seam height of steel plate and steel bar?:If the steel plate surface and steel end vertical welding, welding angle height depends on the diameter of the steel, general welding angle height is 0.7 times the diameter of reinforcement;
Q:Grade 1 steel is round steel, grade two steel is ribbed thread steel. Are the weight of the two units the same?
Grade two steel is ribbed steel, but the average diameter is calculated. The chemical composition of grade steel and grade two steel is different, but the density of them is the same. Therefore, the unit weight of grade 1 steel and grade two steel is the same.
Q:The difference between round steel and screw steel
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts, and more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets
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:Which is stronger, steel pipe or round steel? Which is good at bending?
Round bars are, of course, more powerful, but not much higher.
Q:Do you need paint for roof lightning proof steel bars?
If the metal surface is coated with a thick layer of insulating paint, it will seriously affect the flashover effect. In the national standard, the metal roof is directly used as a flash receiver. The thickness of the paint used on the roof must be less than the required value. That is what it means.
Q:20 round bars are of several grades
At different levels of chemical composition, because of the reinforcing of different chemical composition of the steel, the mechanical indicator will be different. One, two, according to the social needs of Sansteel production power and the development of the material standard, the yield strength, ultimate strength, elongation, low temperature, and weldability are very different, different levels of steel position also have great cooperation. First grade steel yield strength 235MPa, ultimate strength 310MPa, grade two steel yield strength 335MPa, ultimate strength 510MPa, grade three steel yield strength 400MPa, ultimate strength 600MPa.
