henan star cable co., ltd. mainly produces steel cable, steel strand, prestressed concrete with steel strand, prestressed steel strand, unbonded prestressed steel strand etc. Products are widely used in highways, railways, large-span viaducts and other large-scale projects.
Every time you walk through the construction site, you can see a seemingly not thick steel wire on the crane, which can lift several tons of cement and building materials, and you can feel how strong the load-bearing capacity of this steel strand is. There is a Chinese saying that "one chopstick is gently broken, and ten pairs of chopsticks are firmly held into a group". However, the prestressed steel strand is not "held into a group" in this simple sense, but needs a special process to be twisted. If the technology is improper, it will not produce the effect of holding the group to bear the strength.
The weight of steel strands twisted by different numbers of steel wires is also different, but the total load-bearing capacity cannot be obtained by simply multiplying a load-bearing capacity with a specific number of wires. Instead, these specific load-bearing capacities are calculated through special workmanship. General manufacturers will mark the products when they leave the factory, so users only need to choose the corresponding thickness of steel strand according to their own needs.

The prestressed steel strand is a steel cable composed of a plurality of high-strength steel wires. Its tensile strength is very high, its relaxation performance is good, and it is relatively straight when it is unfolded. When making prestressed steel strands, it is necessary to blanking according to the length required by the design, and 200mm long should be set aside on the basis of the length required by the design during the construction of the first hole box girder, and then the blanking length of the steel strands required by the subsequent box girder should be adjusted according to the construction of the first hole box girder, with an allowable length error of 10mm.
Prestressed steel strand is mainly used in the construction of bridges, roads, airports, water conservancy dams and other projects. In terms of material selection, the prestressed steel strand is mainly made of high-strength steel wire, and its material selection should meet the requirements of relevant standards and specifications. In addition, the prestressed steel strand can also be used as a bearing cable, a stay wire, a reinforcing core, a prestressed material, etc. of a wind turbine generator.
In the bridge, water conservancy, energy and construction and other industries, prestressed steel strand is widely used in the construction process of floor and foundation engineering. In fact, not only that, due to the acceleration of urban construction, the use of steel strand is also constantly expanding. For example, high-altitude cleaning buildings and other service companies, as well as some processing engineering service companies, need to use this kind of steel wire with relatively large bearing weight, but the overall weight is relatively light and the quality is relatively good, which can ensure personal safety. To ensure that high-altitude operations are not affected by the wind, but also to protect the person. The prestressed tension value of steel wire is its bearing value. Although its bearing weight is proportional to its thickness, it should be used as much as possible to meet the needs, otherwise it will cause unnecessary waste.
In addition to the core technology of the products, the powerful prestressed steel strand manufacturers also have high product process improvement in their production. If a manufacturer does not have good process improvement in their production, the subsequent products may have no performance in use, or it is difficult for users to have good satisfaction in service life, etc.
In the production of prestressed steel strand manufacturers, what kind of materials are used, what kind of products will be produced. Many of the performance of the product is determined by the material, manufacturers should be responsible for the user, the use of good raw materials, for the user to produce a assured qualified product.
