Section Steel Introduction: Hot-rolled deformed steel rebar are finished steel bars formed by hot rolling and natural cooling. They are made of low-carbon steel and ordinary alloy steel pressed at high temperatures. They are mainly used for reinforcement of reinforced concrete and prestressed concrete structures. They are one of the most widely used steel products in civil engineering. Hot rolled steel rebar is 6.5-9 mm in diameter, most of which are coiled into coils; those with a diameter of 10-40 mm are generally straight bars with a length of 6-12 meters. Hot-rolled steel bars should have certain strength, that is, yield point and tensile strength, which are the main basis for structural design. There are two types of hot-rolled round steel bars and hot-rolled ribbed steel bars. The hot-rolled steel bar is soft and rigid, and it will shrink when it breaks, and the elongation is large. Technical Parameters: Production Process: Advantages and Application: Concrete is a material that is very strong in compression, but relatively weak in tension. To compensate for this imbalance in concrete's behavior, hot rolled deformed steel rebar is cast into it to carry the tensile loads. Most steel reinforcement is divided into primary and secondary reinforcement. It is also employed to confer resistance to concentrated loads by providing enough localized resistance and stiffness for a load to spread through a wider area. Steel rebar may also be used to hold other steel bars in the correct position to accommodate their loads. Delivery and Packing: FAQ: Q: How your quality guarantee?
