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:Embedded bolts M24 why use M25 round steel?
The problem is that the reinforcement of this 36 is not ordinary steel. This steel bar is called general round bar, and its diameter is 36.2MM. Its concentricity is very high, it is a kind of reinforcing steel that is specially designed for bolt
Q:12mm Round steel, the material is Q235, the maximum weight can bear?
Standard Specification for hot rolled round steel is 5.5-250 mm. Among 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:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
The main differences are in mechanical properties. I don't know very well how to make round steel, I can't compare it. Forged round steel is expected to be used in the processing of some special performance requirements.
Q:The difference between galvanized round bar and galvanized flat steel?
Galvanized 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. Round steel is not the same as other steel bars. Round steel is round in shape and has no ribs and no ribs, which makes the bonding strength between round bar and concrete very small.
Q:Is yuan steel round steel?
3 strength, steel and other steel with high strength low strength, namely, diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, and it reinforced the deformation the break before the much smaller.
Q:Round bars and ribbed stirrups are much better
The flexibility of hot rolled round steel bar is better than that of ribbed steel bar, and its fatigue stress amplitude is wide allowable. It is suitable for the components under dynamic load, as well as lifting rings, rings and lifting workpieces;
Q:What are the differences between hot rolled stainless steel rounds and cold drawn round ones?
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. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
Q:How to make the round welds on flat steel flat and qualified?
It is required that the current is suitable and the bar is stable. If required, the groove can be turned on the round steel to ensure that the welding is beautiful and qualified
Q:Which is hard, round steel or screw steel?
If the diameter is the same, of course, the rebar is of great hardness.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.
