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: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:How do you know the diameter and weight of a round bar?
The weight divided by the length is the bottom area of 2, Wu R - is the bottom area. The diameter is equal to 2R
Q:Is round steel round 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. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.
Q:What is the difference between a circle and round steel continuous casting
Round steel drawn from a continuous casting is called a round billet; the rolled round steel is called a bar.
Q:Why is the round bar bent?
In fact, the stress and deformation complex around reinforced concrete, bond stress varies with grip length of the rebar so bond strength with steel type, shape and position of the embedded in concrete, different direction and change, is also related to concrete strength, concrete compressive strength the higher the strength, the bond strength is generally determined by R=P/3.14dL. P for pullout force, D, rebar diameter, L, steel embedment length.
Q:Can the same grade steel instead of round bar be ok?
The above analysis, threaded steel than round steel performance is good, in general circumstances can be replaced.
Q:Do you need paint for roof lightning proof steel bars?
The roof of the round steel as long as the welded joints painted anti rust paint is good, should not be painted a large area. When the flash device is made of steel material, hot-dip galvanized steel shall be used and corrosion resistant by zinc plating.
Q:20 round bars are of several grades
No. 20 cold drawn steel belongs to high quality low carbon steel, cold extrusion, carburizing hardened steel. The steel has low strength, toughness, plasticity and weldability. The tensile strength is 355-500MPa, elongation is greater than or equal to 24%.
Q:Is there any technique for welding round steel?
The welding position is horizontal fillet welding, to control the size of the weld pool of available elliptic transport method the molten iron is brought up, and then try to consider the position of welding welding (a little more than half of small to)
