HeBei Hylite New Technique High Speed Cold Rolled Ribbed Machine
Ribbed rebars cold rolling mill, also called cold rolled ribbed steel bar making machine, is a kind of wire processing equipment using wire rods to produce round or ribbed rebars by reducing its diameter and embossing on the surface. The product ribbed rebars are usually use for prestressted concrete for construction industries, bridging, tunnels etc.
What is the use of cold-rolled ribbed steel in construction?
Cold-rolled ribbed steel bars are widely used in construction. It is often used to make reinforcement of concrete components such as floor, wall, ring beam, foundation beam, etc. The cold-rolled ribbed steel bar has good bonding property with concrete, which can effectively transfer stress and improve the bearing capacity and stiffness of the member. Compared with the hot-rolled steel bar, the cold-rolled ribbed steel bar has higher strength and better ductility, which can meet the requirements of the building structure.
The application of cold-rolled ribbed steel bars can improve the safety and durability of building structures. It can enhance the crack resistance of concrete members, reduce the generation and development of cracks, and improve the overall stability of the structure. In addition, the cold-rolled ribbed steel bar also has good corrosion resistance, which can extend the service life of the building.
In the architectural design, the designer will choose the appropriate specifications and grades of cold-rolled ribbed steel bars according to the stress and use requirements of the structure. The diameter of cold-rolled ribbed bars is usually small, generally between 5 mm and 12 mm, which allows it to be applied more flexibly in members of different sizes and shapes.
It should be noted that when using cold-rolled ribbed steel bars, they must be operated in strict accordance with the relevant design specifications and construction standards. In the construction process, it is necessary to ensure that the laying position, quantity and anchoring length of the steel bar meet the requirements to ensure the quality and safety of the building structure.
What are the advantages of cold-rolled ribbed bars?
Cold-rolled ribbed steel bars have many advantages. First of all, its strength is high, it can withstand large loads, and improve the carrying capacity of the building structure. Secondly, the ductility of cold-rolled ribbed steel bars is good, which can better absorb energy during the stress process and improve the seismic performance of the structure. In addition, its surface with ribbed, and concrete bonding force is strong, can effectively avoid the slip between the steel bar and concrete, improve the integrity of the structure.
Compared with ordinary steel bars, cold-rolled ribbed steel bars also have the advantage of saving steel. Due to its high strength, the use of steel bars can be reduced, thus reducing engineering costs. At the same time, the production process of cold-rolled ribbed steel bars is relatively simple and the cost is low, which is of great significance for the economy of engineering construction.
Cold-rolled ribbed steel bar also has good machinability, can be processed and connected by bending, welding and other ways to meet the needs of different structures. It has high dimensional accuracy, easy installation and construction, and can improve construction efficiency and quality.
In addition, the application of cold-rolled ribbed steel bars is also conducive to environmental protection. Its production process is relatively energy efficient and has little impact on the environment. At the same time, the use of cold-rolled ribbed steel bars can reduce the consumption of steel, reduce the waste of resources and environmental pollution.
In summary, cold-rolled ribbed steel bar has been widely used and recognized in the construction field due to its advantages of high strength, good ductility, high adhesion with concrete, steel saving, good machinability and environmental protection.
