Cold-rolled ribbed steel is composed of two varieties of steel ribbed steel bars and plain bars with ribs, which is a cost effective composite steel material. It has many advantages, such as light weight, excellent bending performance, good overall bearing capacity, clear texture, good welding performance and so on.
Cold-rolled ribbed steel bars are hot rolled from special structural shaped steel. After the steel bars pass through the rolling mill, their cross-sectional areas are slightly decreased in order to increase their strength and rigidity. The cold-rolled ribbed steel bars can be further strengthened by adding ribs to create a specific shape. The ribs are usually composed of two parallel ribs and are usually perpendicular to the longitudinal axis of the bar. This structure reduces the weight of the steel while increasing its strength and rigidity.
The cold-rolled ribbed steel bars are generally made up of two types of steel: high and low carbon steel. High carbon steel is suitable for structures that require high strength and stiffness, while low carbon steel is typically used for structures where flexibility and impact resistance are necessary.
The cold-rolled ribbed steel bars have some advantages, including a wide range of sizes, good weldability and cost effectiveness. They can be easily bent, making it possible to fabricate complex structures from the bars. The bars are often covered with a protective layer of rust-proof paint to prevent corrosion. The bars can also be cut into different shapes and sizes for more specialized applications.
Cold-rolled ribbed steel bars are most commonly used for the construction of steel bridges, buildings and other kinds of structures. The bars are also used for the manufacture of pipelines, ships and other large vessels, and for fishing and farming purposes. For example, the bar can be used to construct the frame of a boat or as a support structure for an irrigation system.
Cold-rolled ribbed steel bars have a number of different applications, including being used to construct roofing systems, paving foundations, support structures, and guard rails. These bars are also used as reinforcement, in seismic retrofit as well as in riveted or bolted structures. They are highly versatile and can be used in both interior and exterior surfaces, making them an ideal choice for many different types of projects.
