Q:Why is a steel rope made of many wires rather than a round bar of steel?
The multi ply, in order to increase the cross-sectional area increases the tension will not suddenly broken, fine wire bend more easily, so the bending of wick core can be better, with better lubrication of steel wire rope. If it is a steel bar, it is not easy to bend, it is easy to break suddenly, and the practicability is poor.
Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
See more big steel bar, there is theoretical weight. After all, rebar is threaded, and round steel is also used.
Q:Are more bars used in high-rise buildings?

Q:4145H round steel is equivalent to the domestic brand?
4145H is round steel, oil drilling steel, domestic steel, Xingcheng Special Steel, steel and other steel mills have production in the Great Wall. The industry commonly used 42CrMo instead.
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:What are the differences between hot rolled stainless steel rounds and cold drawn round ones?
The main differences are in mechanical properties. Forged round steel is used in the processing of some special performance requirements. Round steel three processing methods are more common, should be very wide surface.
Q:What is the diameter deviation of 12 mm galvanized round bar?
It is widely used in hardware, building, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
Q:What is galvanized round bar?
A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
