Galvanized Steel WireGalvanized wire is processed from high-quality low-carbon steel wire rod, which is formed by drawing, acid washing, rust removal, high-temperature annealing, and hot-dip galvanizing. It is processed through cooling and other technological processes. Galvanized wire is divided into hot-dip galvanized wire and cold dip galvanized wire (electroplated zinc wire).Learn More

Hot rolled carbon steel tubes are divided into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.
Cold rolled (dial) carbon steel pipe generally are divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel pipe, special-shaped steel pipe.Learn More
- Stainless Steel PipeStainless steel pipe/tube is a kind of hollow long circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, machinery instrument and other industrial conveying pipes and mechanical structure components. In addition, the bending, torsional strength is the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for furniture kitchenware and so on.

- Stainless Steel PlateStainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is a kind of alloy steel that is not easy to rust, but it is not absolutely rust free. Stainless steel plate refers to the air, steam and water and other weak medium corrosion steel plate, and acid resistance steel plate is acid, alkali, salt and other chemical corrosion medium corrosion steel plate. Stainless steel plate since the beginning of the 20th century, has a history of more than 1 century.

Honed TubeHoning pipe generally refers to hydraulic steel pipe. Hydraulic steel pipe is basically divided into fluid pipe and oil steel tube pipe used in hydraulic system, also known as honing pipe.Learn More
Manufacturing
Our steel manufacturing process is exquisite and advanced. rom the selection of raw materials to smelting, forging, rolling and other processes, industry-leading technology is adopted. Strict process control ensures uniform microstructure and stable performance of steel.
Manufacturing Process
Spiral Welded Pipe (SSAW)1.Uncoiling and Straightening: We need to have our carefully-selected steel plates of top quality straightened using the straightening machine to make them flat and straight, which lays a solid foundation for subsequent forming and welding.
2.Forming: Under the action of the forming machine, the steel plates pass through multiple passes of forming rollers and are gradually curled into a tube shape. During the molding process, it is crucial to control the spacing and speed of the rollers to ensure the accuracy of the tube diameter and wall thickness.Learn More
Wire Rod1. Billet Conditioning: This process is intended for checking the surface quality of billet and removing any defects. Shot blast is used to remove any scale from the surface. Magnet particle testing and visual inspection are also used to identify any defects which must be removed using a grinder. Ultrasonic testing and dimension and geometry checking are also applied as part of the internal quality assurance process.
2. Reheating: The temperature within the furnace and the duration of reheating depend on where the product will be used. To avoid decarburization, which can affect the surface quality of the product, a billet is pre-heated sufficiently at a low temperature before being rolled within the reheating furnace. For this purpose, the fuel and air ratio are strictly controlled.Learn More
Steel Plate1. Rolling: The 4-high reversible finishing mill with the maximum load of 7000 tons minimizes internal defects even inly thick plates. Automatic gauge control and shape control systems can reduce not only the thickness deviation of plates but also improve the flatness.
2. Cooling: The cooling system enables the production of high strength steel without heat treatment through rolling and accelerated cooling. Using the mist cooling method with suction type, the system has a high cooling capacity and is able to maintain a uniform temperature gradient in the widthwise direction. This leads to a reduction of plate quality deviation.Learn More
Stainless Steel1. Steel Making: Steelmaking has the greatest impact on the quality and cost of steel products. We has state-of-the-art AOD, VOD and continuous casting facilities..
2. Hot Rolling: Slabs made in the steelmaking plant are rolled into black coils of highly refined thickness and shape before being made into white coils to the needs of customers through heat treatment, pickling and finishing in the annealing and pickling plant. White coils so produced are used for cold rolling, pipes and sheets.Learn More
Hot Rolled Steel1. Reheating: Hot rolled coils pass through a pickling line, where scale breaker machines and hydrochloric acid solutions are used to remove any surface scale and/or oxide film that which causes surface flaws during the final stage of cold rolled steel processing.
2. Roughing: In this process, slabs whose surface scale share has been removed are made into rolled materials with the proper shape, thickness, and width. In the entry and exit area of the roughing mill, an edger rolls the strip in the width direction using an Automatic Width Control (AWC) system.Learn More
Electrical steel1. Preliminary Annealing: During the preliminary annealing process, a scale which may have formed on the hot rolled steel is removed as delayed passing through scale breaker and a hydrochloric acid bath. This initial heat treatment process improves the cold rolling properties of steel as well as its magnetic properties.
2. Cold Rolling: In order to obtain specific thickness and material properties, a reduction ratio of 40-90% is applied normally. Rolling and edge trimming machines are automatically controlled to obtain uniform thickness and width.Learn More
- Cold Rolled Steel1. Pickling: Hot rolled coils pass through a pickling line, where scale breaker machines and hydrochloric acid solutions are used to remove any surface scale and/or oxide film that which causes surface flaws during the final stage of cold rolled steel processing.
2. Cold Rolling: Pickled coils are cold rolled in tandem mills to a specified thickness, typically 40 to 90%, of original material dimensions. Fully automated shape adjustment is ensured through state of the art process machinery.Learn More
Galvanized Steel1. Pre-Treatment Process: Some rolling oil and other contaminants remain on the surface of cold rolled steel sheets following processing. These are removed by passing the electrically charged sheet through an alkaline solution which induces an electrochemical reaction.
2. Annealing: The material properties of the pre-treated steel sheet can be altered and improved through recrystallization during the annealing process.Learn More
- Electrical Galvanized Steel1. lnput Process: Equipment at the entry point of the electrogalvanizing line consists of a pay-off reel, a shearing M/C, a welding M/C, a looper and a tension leveler. The pay-off reel transports stacked or cold rolled steel materials to the shearing machine which cuts and connects them in preparation for welding. Then comes the welding.
2. Pre-Treatment Process: An electrolytic cleaning line consists of an electrolysis tank, an acid bath and a rinse tank to remove contaminants and oxide films from the surface of the steel before electroplating.Learn More
