Latest China steel market message

Dear My friend concerning China SteelThe government is still strict on the environment protection. Just now, the biggest steel raw material factories have closed their warehouse one by one. The situation is still tense。AllenChunpeng PC Strand(www.pcstrand.cn)

The situation about the present China Steel Market

Many Customers have found China's steel market has been in a disorderly chaotic state since 2016, performing fluctuating steel price. Most our clients often complain to us: "Why are your prices so high?" "Why did your price fall so much?" "Why did your price increase so fast?" Such questions are endless.I believe that 99% answers you heard are: I don’t know. As for the remaining 1%, You got none.Indeed, we really do not know. We do not know why 603$/Tgalvanized pipe yesterday rose 15$ today; we do not know why 706$/T pc strand change to 676$/T; we do not know why obviously a good 15-day delivery at the beginning and finally Into 30 days; because the market is too damn messy.I am not a professional market analyst, nor the executive in charge of the market, I am just a sales, so I can not predict the future of the Chinese steel market, the best I can do is sharing all the information to everybody.At present, environmental protection can be described as the largest enemy of the steel market. Two weeks ago, the CCTV(government media) reported the problem of industrial waste discharge in North China.We can see how thrilling the problem is through these pictures. So I think you should be able to understand the decision of Chinese government on pollution control. The above new directly led to strongly environmental protection inspections in North China, 80% of the factories has been cut off for rectification.The further reflection of environmental protection manifests in two aspects: First, unstable price., the price keeps ups and downs in the past two weeks, just kidding, like in a roller coaster. So most of the factories in China chose to stop offering, and even leave the workers; Second, the uncertainty of delivery. The direct result of stop-production is unable to determine the delivery period, although some factories are only in secret production at night.Of course, environmental consolidation is also beneficial in some way. This is process the Chinese steel industry must go through, which the American, Britain, Japan's steel industry have experienced before.On the one hand, you can eliminate a large number of high-pollution and low-quality factories to enhance the quality level of the product market; on the other hand, this is for the future development of China, taking into account the economy and the environment.Wish China will be Stronger and Better!

Something you should know about the rust of PC Strand

Our first-met customers sometimes complained to us that the PC Strand bought from others got rusty. So they repeatedly emphasized the importance of rust-proof. Now I am going to say something about issues related to the rusting of PC steel strand.Rust-proof was starting from raw materials .That’s why we,Chunpeng pc strand, use high-quality 77B/82B wire rods. Before putting the wire rod into the drawing machine, surface treatment is necessary , there are two types: mechanical descaling and acid pickling. Mechanical descaling, also known as physical removal, is a physical grinding methods to remove rust stains, environment-friendly but not completely derusted. Chemical descaling --- acid pickling is soaked in chemicals, derusted better but seriously polluted.Rust is starting from this process.Judging from the effect of derusting, acid pickling significantly superior, but as we all know, the Chinese Government start to strengthen environmental protection from 2016, leading to capacity-limited of major steel mills. So the factory will choose mechanical descaling to keep producing,but it also causes to rust during storage later. Meanwhile, if the oil spread nonuniformly or using poor quality oils, this can also lead to rust.Improper packaging can lead to rust.During the process of container-shipping, if the export packing is not correct, it's easy to rust in wet conditions. While ChunPeng PC strand takes most waterproof packaging, EIGHT steel bars fixed, TWO layers plastic wrap, isolating the contact of PC strand and steam.If PC Strand is unfortunately rusted, then it also depends.Minor rust has little influence on using, only unattractive in appearance, but we also need to use wire brush to remove rust stains, otherwise it will decrease the anchoring strength with concrete. But severe rust resulted in a reduction of performance to 90% will greatly affect the application, then you need to claim for your lose.Anyway, I hope everyone could pay more attention to these details during the procurement of PC Strand to avoid rusting of steel strand. Or you can just buy PC strand from us -- CHUNPENG PC STRAND, then you will feel less worried about products you buy. We will provide you with the latest information on our website: http://www.pcstrand.cn 

What's PC WIRE?

PC WIRE, prestressed concrete steel wireMore details please to http://www.pcstrand.cn/pid18079602/High-tensile-astm-a421-5mm-concrete-wire.htmIntensity: 1470Mpa-1770Mpa. Standard: ASTM, BS, DIN, GB. Wire Diameter: 4.00mm-12.00mm.   Types of prestressed PC steelwire:1,According to diameter and can be categorized as: 4mm, 4.8mm, 5.0mm,5.1mm, 6.0mm, 6.35mm, 7.0mm, 7.8mm, 8.0mm, 9.0mm, 10.0mm, 11mm, 12mm and so on.,2,According to intensity level can be classified as: 1470MPa, 1570MPa,1670MPa, 1770MPa and 1860MPa.3,In accordance with the surface coating, high tensile PC steel wire canbe classified as: no coating prestressed steel wire,prestressed epoxy coated steel wire and galvanizedprestressed steel wire.4,In accordance with the surface morphology can be classified as: light round prestressed steel wire, spiral rib (spiral ribbed or helix grooved)prestressed steel wire, the pressure wave(crimped) prestressed steel wire or nicks (indented) prestressed steel wire andso on.5,In accordance with treatment process can be categorized as follows:cold-drawn prestressing steel wire (no slack performance requirements) and lowrelaxation prestressed steel wire.Prestressed PC steel wireapplication: Prestressedconcrete strand is used of prestressed concrete structure reinforced, such aslarge-span bridges on railway and highway, overhead crane beam, rock-soilanchoring project, multi-storey industrial buildings, stadiums, mines and etc.PE coated steel strand for prestressed concrete is suitable for large-span andlarge bays cast-in-place concrete floor, large load of precast beams and otherspecial structure.


PC STRAND, prestressed concrete steel strand ,is a twisted steel cable composed of 2, 3, 7 or 19 high strength steel wires and is stress-relieved (stabilized) for prestressed concrete or similar purposes. 1. ClassificationAccording to the number of steel wire in a strand: 2 wire strand, 3 wire strand, 7 wire steel strand and 19 wire steel strand.According to the surface morphology can be divided into: smooth steel strand, scoring strand, mold pulling strand (compact), coated epoxy resin steel strand.They can also be classified by diameter, or intensity level, or standard.2, SpecificationsIn the description and list of the table we often see, there are 15-7Φ5, 12-7Φ5, 9-7Φ5 and other specifications of the prestressed steel strand. To 15-7Φ5, for example, 5 said a single diameter 5.0mm of steel, 7Φ5 said seven of the steel wire to form a strand, and 15 that the diameter of each strand of 15mm, the total meaning is "one The beam consists of 7 strands of diameter 15 mm (each having a total diameter of about 15.24 mm, a dimensional deviation +0.40 -0.20; a diameter of about 5.0 mm per filament). The general sectional area is calculated according to 140mm ^ 2. The theoretical breaking value is 140 * 1860 = 260.4kN, which can withstand the tension of 156.24-169.26kN according to the prestressing standard of 60% -65%. 3.MaterialsUsing high-carbon steel wire rod, after surface treatment of cold drawn into steel wire, and then by the strand structure will be a number of steel wire stranded into shares, and then through the elimination of stress from the stabilization process. In order to extend the durability, the wire can have metal or non-metallic coating or coating, such as galvanized, epoxy resin coating. In order to increase the bond strength with the concrete, the surface can have nicks and so on. The prestressed strands of the mold are twisted to form a mold compression process, the structure is more compact, and the surface layer is more suitable for the anchor. Production of unbonded prestressed steel strand (unbonded steel strand) using ordinary prestressed steel wire, coated with oil or paraffin after the package of high-density polyethylene (HDPE) into. 4,FeaturesThe main characteristic of the prestressed steel strand is high strength and relaxation performance is good, the other when the more straight. Common tensile strength level of 1860 MPa, as well as 1720,1770,1960,2000,2100 MPa and the like intensity level. The yield strength of this steel is also higher. 5,ApplicationIn most of the post-tensioned and pre-tensioned prestressed project, smooth steel strand is the most widely used prestressed steel. Stranded strand is mainly used to enhance the project, but also for nuclear power and the like works. Galvanized steel strand commonly used in the bridge of the tie rod, cable and external prestressing works. Epoxy coated steel stranded wire is similar to galvanized prestressed steel wire.6,StandardCountries have standards for prestressed strand, such as: China Standard GB / T 5224, American Standard ASTM A416, British standard BS 5896 and the Japanese standard JIS G3536, the Australian standard AS / NZS 4672, Brazilian standard NBR-7483
