15.2 steel strand is also widely used in the construction of new major buildings. It is mainly used in bridge construction, which can improve the stability of bridges and bring a great sense of security to people. 15.2 steel strand is a steel product composed of multiple steel wires. The carbon steel surface can be plated with zinc, zinc-aluminum alloy, aluminum, copper, or epoxy resin coating as needed.

　　At present, the role of 15.2 steel strand is becoming increasingly important. Some people also need to use 15.2 steel strand during construction, but there are many precautions in the process of using 15.2 steel strand. First, welding is not required during the use of steel strand. Why is that? The main reason is that the weld strength is low, which easily causes wire breakage and affects normal use. Second, when using steel strand, it is usually left-handed.

　　You need to work according to the regulations. If there are any special needs that may be disclosed in the construction contract, it is necessary to check carefully. Of course, a project requires the use of 15.2 steel strand. It is recommended that you find a professional construction team to implement it. Only in this way can we ensure the smooth progress of the project. After completion, a detailed acceptance is required to ensure the correctness of the project. The manufacturing process of steel strand can be divided into single-wire production and single-wire production. Single-wire production mainly uses wire drawing technology, and different raw materials can be selected according to the material of the product, such as steel wires used for electroplating and heat treatment.

　　In the manufacturing of twisted pairs, many steel wires are also used to synthesize steel wires. Therefore, different manufacturing processes also determine that steel can be used in different fields.

　　What are the methods to improve the appearance and corrosion resistance of 15.2 steel strand? The usual method is to apply a protective coating to the steel strand. There are two types of protective layers: metallic protective layers and non-metallic protective layers; metallic protective coatings include galvanizing and copper plating, and non-metallic protective layers generally use epoxy resin coatings.

　　Epoxy coating products are also produced abroad, but the processes are different. The foreign choice is to spray quartz sand on the surface of ordinary smooth steel wire or steel strand to enhance friction, and then apply an epoxy resin coating on the outer layer. Based on later patents, the epoxy resin coating, namely the spiral rib, is used, avoiding the sandblasting process and having stronger grip than traditional products.

　　Prior to this, only two domestic production lines were imported from abroad. The epoxy coating production line is independently researched and manufactured in China, achieving the goal of equipment localization. At the same time, the physical and chemical properties of epoxy resin steel strand have also been improved. Its equipment and production technology have reached the internationally advanced level.

　　15.2 steel strand has received widespread attention for its excellent corrosion resistance. The steel bar has low frictional force and is easy to bend into a multi-span curve shape. It is especially suitable for continuous reinforcement of large-span floor slabs and roofs. In China, steel bars include steel strand steel bars and wire strands, commonly known as steel strands and wire strands. They are coated with special anti-corrosion lubricating grease, such as steel strand or wire strand. Polyethylene is used as the sheath, and the commonly used plastic is low-pressure high-density polyethylene.
