Trend of steel strand market in 2020

As China’s one belt, one road construction and the supply side reform on the upgrade of the steel strand industry, the capacity structure has been optimized, the quality of products has been greatly improved, and a large number of high-quality products have gone abroad. However, at the beginning of 2020, the invasion of new coronavirus affected the development of Global trade. The demand performance is beyond expectation, and the market supply and demand balance pattern is still maintained. The author analyzes and prospects the steel strand market situation in 2020 from the following aspects.

Overview of pc steel strand Market

The steel strand is a steel product composed of several steel wires. According to the needs, zinc coating, zinc aluminum alloy coating, aluminum coating, copper coating and epoxy resin coating can be added on the surface of carbon steel.

Steel strand can be divided into: prestressed, unbonded, galvanized steel strand, etc. This paper only introduces the prestressed steel strand with the largest market circulation and consumption. Prestressed steel strand is a stranded steel cable composed of 2, 3, 7 or 19 high-strength steel wires, which has been stress relieved (stabilized).

The main features of strain steel are high strength and good relaxation performance. In addition, it is relatively straight when it is unfolded and suitable for prestressed concrete or similar purposes. It is widely used in high-speed railway construction, expressway and national and provincial highway bridge and other infrastructure projects.

China’s prestressed steel strand industry originated in the 1960s, began to introduce western technology in 1988, and began to develop rapidly after 1995, mainly due to the sustained growth of China’s economy and the country’s policy of continuous investment in infrastructure. Now China has become the largest prestressed steel strand consumer market in the world.

Base of Steel strand

At present, the production bases of steel strand are mainly in Tianjin, Jiangsu, Hebei and Henan, which account for 70% of the total output of the country.

Tianjin has obvious location advantages, and the logistics in the center of the North-South channel is more convenient, which can easily radiate Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia and northeast provinces. Due to the development of Tianjin strand industry cluster, the steel production of iron and steel enterprises in the region is driven, and many steel enterprises in the region provide sufficient raw material supply.

Manufacturers along the Yangtze River mainly radiate to Jiangsu, Zhejiang, Shanghai, Fujian and Guangdong, benefiting from the developed inland water network transportation and low freight. There are also many well-known steel mills in the region as raw material suppliers with sufficient supply.

The application of steel strand in China

Steel strand is usually used for supporting cable, stay wire, reinforcing core, etc. it can also be used as the ground wire of overhead transmission, the barrier cable on both sides of the road or the structural cable in the building structure. The commonly used prestressed steel strand in the prestressed steel strand is the uncoated low relaxation prestressed steel strand, which is also galvanized. It is commonly used in bridges, buildings, water conservancy, energy and geotechnical engineering, etc., and the unbonded prestressed steel strand is commonly used in floor and foundation engineering, etc. The steel strand is an indispensable material in the construction engineering. The steel strand is a steel product composed of several steel wires. The surface of the carbon steel can be added with galvanized layer, zinc aluminum alloy layer, aluminum clad layer, copper plating layer, epoxy resin coating, etc. as required. Different classification products have different applications.

Future development trend of steel strand industry

With the continuous breakthrough of technical barriers in China’s steel strand industry and the involvement of private capital, the proportion of private enterprises keeps rising. In 2018, China’s new steel strand capacity is about 400000, and in 2019, the effective capacity has reached as much as 6 million. In the future, the competition in the industry market will be particularly fierce, in which the large manufacturers and brand manufacturers occupy the high-end market through their own brand advantages and long-term customer resource advantages established through cooperation, while some private manufacturers compete by regional sales mode and low-cost cash sales, resulting in many steel strand manufacturers’ output increasing while their profits falling, or even losses. Therefore, the future market urgently needs the supervision and coordination mechanism.

From 2010 to 2020, the state will focus on the construction of passenger dedicated lines, intercity rail transit and coal transportation channels, and initially form a high-speed railway, rapid passenger transport and coal transportation network. There are 13 railway projects and 8 railway coal transportation channel projects in Xinjiang included in the 12th Five year development plan of the Ministry of railways, which will be conducive to stimulating the market demand for stranded wires.

Thanks to the continuous growth of China’s economy and the state’s policies on infrastructure investment, China’s prestressed steel strand industry has become a super giant in the global industry, far larger than the total scale of European and American enterprises. The increase in infrastructure investment such as bridges, railways and expressways has provided a strong support for the prestressed steel strand market, and the industry is booming. With the implementation of one belt and one road, the investment boom of infrastructure construction will bring more room for development of the prestressed steel strand market.

Top 3 most common hydraulic seals

There are a lot of industrial application require various types of seals in order to ensure that replacement and upgrade will be simple. This is the business that will need profit and revenue. As a result, if production has been stopped, profit will also cut down. Because of that, workers and specialists in this business would have to ensure that every machine will be running smoothly and reliable for their jobs. Hydraulic seals are devices that have various types such as the rod seals, Teflon products and the o rings. Replacing or upgrading hydraulic cylinders and other equipment for industrial applications will be manageable by installing the various types of hydraulic seals.

The most popular series of hydraulic seals has to be the rod seal. This is a subdivision of radial seal that is specialized in encasing axle. An average person may pick the best deal to buy in case this device is to be replacing or upgrading.

The piston seal is a different kind of the hydraulic seal. It is actually another variation of the rod seal. This is also designed for encasing axle but will have another way when it comes to replacing or installing the part. With the rod seal, the o ring will seal inside of the shaft. But with the piston seal, the o ring becomes in touch with the encasing axle itself. The other kind is the Teflon products. This applies symmetrically or will be positioned the same as the rod seal or piston seal. The industrial market will favor these sealants in order to ensure that each and every part of their products will be functional and effective in the operations.

In other business, there are also other types of hydraulic fluid that are being applied for replacement and upgrade. These hydraulic fluid will assist the business acquiring reliable equipment and device. These hydraulic fluid can assist in replacing, upgrading and improving equipment and device that are apply in many various businesses.
