Q:Why is it better to use round steel than flat steel in lightning protection?
In the construction of lightning protection, both round bar and flat steel have different uses. Flat steel is generally suitable for horizontal connection between vertical grounding poles for lightning protection. Round steel is suitable for lightning protectionThe guiding line and connected with lightning. The roof, all of the junctions are connected by welding requirements do not exist, what striking issues... The technical norms of the state said so, does not have what good and bad problem
Q:Is the shear wall concealed column stirrup steel or round steel?
Specify the construction drawing is HPB300 is hot rolled round bar, that is HRB335, HRB400 is the hot rolled ribbed bar. Don't call thread steel, this name has long been abandoned. Simple, light marked wall column reinforcement detail construction drawing on the diameter and spacing is not encrypted, what non encrypted area, like the dense spacing.
Q:What is the reason that the diameter 130-45 round steel will break after welding?
Steel No. 45 belongs to medium carbon steel. Because of its high carbon content, it has poor weldability, but its comprehensive property is good. If welding is needed, it needs to be preheated before welding and heat treated after welding to reduce its internal stress. The more commonly used weldability is No. 20 steel. In order to improve the performance of No. 20 steel, heat treatment is usually applied to its surface.
Q:What are the scientific names of round bar and screw steel?

Q:20 round bars are of several grades
20 round bars may be grade two steel.
Q:What is galvanized round bar?
