The difference between steel bars and rebars
These differences reflect the differences between prestressed steel bars and steel bars in terms of material properties, manufacturing processes, and application areas. Prestressed steel bars are mainly used in situations where high strength and special mechanical properties are required, such as in prestressed concrete structures, while rebars are widely used in ordinary building structures.

Which is stronger, steel pipe or iron pipe?
Although iron pipes and steel pipes each have their own scope of application and advantages and disadvantages, in terms of strength, steel pipes perform better in extreme environments due to their higher strength and corrosion resistance. Therefore, it can be considered that steel pipes are stronger than iron pipes.
Is the steel coil cold rolled or hot rolled?
Steel coils can be hot rolled or cold rolled, depending on the production process and the desired end product characteristics.
The difference between angle steel and angle iron
Although some literature may mention that there are differences in the materials of angle iron and angle steel, in daily use and in the field of construction, they are usually regarded as different names for the same material. Therefore, when "angle iron" is mentioned, it actually refers to the same product as "angle steel", that is, a long strip of steel with two sides perpendicular to each other at an angle.
What are the three ways to connect steel bars?
Each connection method has its applicable scope and characteristics. The choice of connection method depends on the specific project requirements and conditions.
What are the surface treatment methods for steel?
The choice of these methods depends on the intended use of the steel, the required surface quality and subsequent processing requirements.
