Nowadays, the application of prestressed concrete steel strands (or saying PC steel strand) has been popularized in an all-round way, the main reason is that it can achieve better quality standards in the process of practical application, give play to better stability and durability in the construction industry, and have a very strong anti-impact ability. the service life is very long and the comprehensive price ratio is very high, which can meet the requirements of different environments. As a new type of building material, PC strand products have become the favorite in the field of construction engineering. It can really play a important role and also fully exploit its use’s advantage and characteristics when applied in architectural field, meanwhile pre-stress concreted steel strand meets the construction requirements during various and different harsh environments, and be more reasonable in price positioning. In short, all aspects of high carbon steel pc strand can meet the requirements of application. Comparing with traditional building materials, it shows excellent features and advantages.


About prestressed concrete strand advantages

Prestressed concrete steel strands entered the practical stage in the 1950s. However, the basic principle of prestress is not only applicable to steel strands, but also applied in many aspects in ancient times. The main purpose of prestressed concrete steel strands are to overcome the disadvantage of low tensile strength of concrete and make full use of high strength carbon steel.


The galvanized pre-stressed concrete steel strand is made by twisting the galvanized prestressed steel wire ropes as a semi-finished product. Base on pc strand adopt steel or iron materials, so we have to consider rust and corrosion issues about iron substrate. Zinc coating has both mechanical and electro-chemical protection effect on iron substrate, at the same time its corrosion resistance property is also good. Compared with the traditional hot-dip galvanizing, galvanizing has the following advantages:


1. The thickness of the zinc coating varies greatly: the thickness of the galvanized coating is generally only 70-150g/m², while the thickness of the hot-dipped galvanized layer is about 300g/m².

2. The adhesion and surface state of electro-dip galvanizing is better than that of hot-dipped galvanizing. It is difficult to control the thickness of hot-dip galvanized coating.

3. The erosion rate of electroplating zinc is slow.


PC steel strands are widely use for construction industry because of its another reason of cost. PC strands are easy to manufacture through steel factories with low cost equipment. So it could be widely purchased by buyers. Meanwhile, the most of oversea construction companies and groups with higher cost conscious, then they plan to purchase pc strand in bulk from countries in Asia, like China, India, etc. Through market report, we may find that the global demand for pre-stressed concrete (PC) wire strand market was 3.4 billion dollars in 2016, and it is expected to grow at a CAGR of around 2.5% from 2017 to 2025, in meantime this trend is likely to be dominated by countries like India and China.
