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:Are lightning checks required for galvanized steel, flat steel and round steel?
No, when purchasing hot galvanized round steel and flat steel, please offer the factory certificate and inspection certificate.
Q:Will the three steel is steel? It is a steel bar?
Your question is inaccurateThread steels are grade two, grade three, grade four, and even grade fiveFirst grade steel generally refers to the wire rod, also known as wire rod, is a ribbed steel bar
Q:How to distinguish a round bar from forging? Cold drawing? Hot rolling?
Hot rolled round steel, used in construction and general hardware parts processing is very common. Cold drawn round steel (do not know is not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
Q:How about the difference between round steel and shaped steel? Where are they mainly used?
Section steel is a general term, round steel is a kind of section steel, mainly used in building structure, mostly for engineering steel.
Q:What is hot rolling? What is called forging?
And there is no essential difference between the rolling and forging are relying on the plastic deformation of the blank but only the blank rolling machine plates or other similar things can be put in the sheet metal forging blank is processed into a more complex shape
Q:Embedded bolts M24 why use M25 round steel?
Why does the embedded bolt M24 use M25 round steel? Because there is no 24 of the bar specifications, only 25
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:Can steel bars be replaced by large screws in the concrete floor?
Equal strength substitution method;The strength of the reinforcement to be replaced must be greater than or equal to the original strength of the reinforcement. The tensile strength of the original reinforcement, the square of the diameter * the tensile design strength / the diameter of the reinforcement to be replaced by the square *, the tensile design strength.
Q:Why do I use the M25 round bar for the embedded bolt M24?
Because M25 round steel machine processing, the direct use of M24 round steel accuracy is not guaranteed
