Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The general market price than ordinary steel galvanized steel bar of your 2000-3000 dollars per ton, according to your purchase requirements, price range of relatively large fluctuations, such as whether to open a formal invoice, transport distance, purchase quantity, relationship with your level of economic development, the developed area of fierce market competition, the price is relatively low. The prices and prices of large factories and small factories are not the same. The prices of big factories are generally high, and the prices of small factories are low.
Q:The diameter of 20 solid round steel bend into a circle, what machine bending?
Steel hoop benderConstruction: steel bending machine is suitable for bending stirrups, the bending angle can be adjusted arbitrarily, the structure is similar to the bending machine.Working principle: motor powered by a pair of wheels and two straight gear reducer, the eccentric disc rotates. The eccentric disc drives two connecting rods through an eccentric hinge, each connecting rod is hinged with a rack, so the rack moves reciprocally along the slideway. The rack also drives the gear to make the working disc reciprocate in a certain angle. The work disc has two axle holes, the central hole is inserted into the central shaft, and the other jack is arranged on the shaft. When the work disc is rotated, the central shaft and the forming shaft rotate together. The same principle of the steel bending machine can bend the steel bar into the required stirrups.
Q:Is round bar steel?
In actual engineering, it is not necessary to use steel bar instead of round steel, but it should not be reversed. In addition, the diameter of the round steel bar is generally not large, but the diameter of the round bar is very large.
Q:What is the difference between strip steel and round steel? Where are they mainly used?
Difference between round bar and other steel bars:(1), is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other.(2) the composition is different. Round steel (grade a steel) belongs to ordinary low carbon steel, and most other steel bars are alloy steel.(3), the strength is not the same, low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:12mm Round steel, the material is Q235, the maximum weight can bear?
Round steel: 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 bar is divided into three parts: hot rolling, forging and cold drawing.
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: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:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
The general anchor bolt is made of Q235 steel, which is round. Rebar (Q345) strength, do nut thread no light round easily.
Q:4145H round steel is equivalent to the domestic brand?
42CrMo steel is ultra high strength steel, high strength and toughness, hardenability is also good, no obvious temper brittleness, after quenching and tempering treatment have high fatigue limit and anti shocksand low temperature impact toughness. The steel is suitable for making large and medium plastic moulds with certain strength and toughness.
Q:Weight algorithm of round steel
Round steel weight = density * volume = density * base area * length of round bar.Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed in diameter, in units of millimeters (mm), such as "50mm", which means a diameter of 50 millimeters of round steel.
