Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The same specification galvanized round steel, more than a round galvanized process, so galvanized round bar price = round bar cost + zinc + processing fee + three costs + wear and tear.
Q:Difference between round bar and other steel bars
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:12mm Round steel, the material is Q235, the maximum weight can bear?
The cross sectional area of 12mm steel is 3.14*36=113.04 mm, the maximum can bear much weight: 113.04*235=26564.40 cattle, is about 26.56440 kn.
Q:Are more bars used in high-rise buildings?
Look at the architectural design requirements and seismic grade, light steel reinforcement is mainly stirrups, columns, beams, shear walls generally use thread steel, plate bars and distribution bars are generally cold and twisted steel bars
Q:How to determine the welding seam height of steel plate and steel bar?
If the end of the vertical plane and the steel plate welding, welding angle as the bar diameter and the general welding height is 0.7 times the diameter of the arc can be reinforced; if the length direction of the surface of steel plate and steel welding, 2 side fillet weld cracks in the welded steel plate and steel between the full and round steel weldment the maximum diameter of arc phase can be flat.
Q:What is round steel?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed as millimeters in diameter. For example, "50" means a round steel with a diameter of 50 millimetersRound bar is divided into three kinds of hot rolling, forging and cold drawing. The specification of hot rolled round bar is 5.5-250 millimeters. Among them, 5.5-25 rounds of small round bars are mostly supplied by straight strips. They are commonly used as reinforcing bars, bolts and various mechanical parts;
Q:4145H round steel is equivalent to the domestic brand?
4145H rounds are used in oil drilling tools and are often replaced by 42CrMo in the industry.
Q:What kind of steel bars are used in general civil buildings?
In the general construction of commonly used hot rolled round bar (commonly known as round steel), hot rolled ribbed steel bars (commonly known as steel), the two most widely used steel. Identified as HPB235, the diameter of 6.5, 8, 10, 12, and then rough is not commonly used, and in the 6.5 and 8 most as commonly used, used as column, main reinforcement and stirrups and plate reinforced beam distribution.
Q:What's the difference between bearing steel and round steel?
Bearing steel refers to the steel used to make bearings. Round steel is generally referred to as round bar steel. One refers to the material, and the other refers to the profiles. Such as bearings, needle roller raw material is round steel, but also bearing steel.
Q:Why do I use the M25 round bar for the embedded bolt M24?
Such as using 24 of the round steel, worried about the surface quality of steel when the processing can not be nominal diameter 24 of the standard thread, of course, the election is too large and wasteful, so generally choose 25 of the round bar,
