Steel wire strands have many uses. For example, they are used in some construction projects, such as the construction of prefabricated beams for bridges and various prefabricated slabs. However, what is closer to our daily lives is prestressed concrete produced with prestressed slabs. The production process of prestressed concrete can be divided into two types. The following text from the steel wire strand manufacturer will discuss the uses and operating methods of steel wire strands.

　　One is the pre-tensioning method, and the other is the post-tensioning method. Now let's take a look at the working processes of these two methods separately. First of all, the so-called pre-tensioning method is mainly to ensure the structure and high performance of the concrete, prestressing must be applied to the concrete structure to ensure its structural integrity. The specific operation is to first pull the framework tight, then straighten it, and then pour the concrete.

　　Next, the post-tensioning method mainly involves pouring the concrete first, then pulling the steel wire strands, but the strands cannot be pulled after pouring. The tension of the concrete should be around 70% to 75%. When we pull the strands, we must also grasp it correctly, mainly mastering the pre-designed load level! Of course, whether it is the pre-tensioning method or the post-tensioning method, our goals are the same.

　　The main purpose is to apply prestress to the concrete. Its function is also to make the overall structure of the concrete more stable and improve the performance of the concrete. Of course, we must also grasp the force well during the specific operation. In addition, speaking of the role of steel wire strands, it can actually be expressed in very straightforward language, that is, to replace traditional steel bars in prestressed concrete.

　　Steel wire strand manufacturers discuss classification

　　Steel wire strands can be classified in various ways according to structure, coating material, use, material properties, etc. Common classification methods include classifying by structure into prestressed steel wire strands, galvanized steel wire strands, unbonded steel wire strands, etc.

　　Steel wire strand manufacturers share the steel wire strand production and manufacturing process

　　The production and manufacturing process of steel wire strands is divided into three parts.

　　One part is the single-wire manufacturing, generally using raw materials such as stainless steel wire, high-carbon steel, or low-carbon steel wire for cold rolling processing to obtain single wires of the corresponding specifications. If a coating is required, the single wires are electroplated. The second part is the strand manufacturing, where the manufactured single wires are twisted together to form steel wire strands of the corresponding specifications. After the prestressed steel wire strands are formed, they need to be stabilized. The third part is packaging and forming. For ease of transportation and use, they are usually shipped in two packaging forms: coilless coils and worker wheels.

　　Steel wire strand specifications and models

　　Common specifications are 1*2, 1*3, 1*7, 1*19, etc. Usually, the single wire diameter is displayed as "1*195", indicating that one steel wire strand is made up of 19 wires with a diameter of 5 mm twisted together.

　　The above is an explanation of the uses and operating methods of steel wire strands provided by the steel wire strand manufacturer. Hope this helps.
