Q:Excuse me, the difference between round steel, screw steel, steel, plate material, steel wire, hope professional answer?
Disk and rebar with rib, have all the same, basically can not see, rebar size is more than Phi 9, a lot of hardness than wire reinforced strong general, so the steel strip is usually linear, bluntly, steel disc is not up, disc. The size can be intercepted, so can be screwed up disc.
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?
Method of calculating reinforcement weight, unit length, weightD*d*0.00617= (6 in 7)For example, 8mm steel 8*8*0.00617=0.39488 take 0.395Round steel and rib are calculated the same wayRound bar 8 is rolled up, usually between 2~4 tonsYou'll have to straighten it up, straighten it up, and straighten it up
Q:45# what are the main rounds for?
45# 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
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:Difference between cold drawn round steel and round steel
Cold formed steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
Q:What is hot rolling? What is called forging?
Forging is a method of processing wool embryos by plastic deformation. They are also classified as cold forging and hot forging
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Round steel (grade 1 steel) belongs to ordinary low carbon steel with low strength. However, the plasticity of the round bar is stronger, that is, the round steel has a larger deformation before it is pulled off.It has been widely used in the fields of hardware, construction, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, space, etc.. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
Q:The difference between round face and round bar steel on concrete?
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:Use of stainless steel round bar?
Stainless steel round bar is a kind of long material, and it is also a kind of bar. The so-called stainless steel round bar refers to the cross section is even round long material, generally about four meters long. It can be divided into light and black. The so-called light circle, refers to the smooth surface after processing and quasi rolling; and the so-called, refers to the surface of the black, coarse, and direct rolling.
Q:1, three, two, steel, wire rod, round steel what is the difference?
Wire is a wire, usually refers to the use of "high speed non-twist wire rod rolling mill, ordinary common low carbon steel, hot-rolled wire torsion free cooling (ZBH4403-88) and the high quality carbon steel, hot-rolled wire rod without torsion cold control (ZBH44002-88).
