Cold drawn steel pipe is produced by drawing hot - rolled or cold - rolled seamless steel pipes through a die at room temperature.
It features extremely precise dimensions with very strict control over outer diameter, inner diameter, and wall thickness. The surface quality is superior, with high smoothness and minimal surface defects. The cold drawing process enhances the mechanical properties, giving it high tensile strength, yield strength, and toughness. It can be made into pipes with complex cross - sectional shapes and very small diameters, which is difficult for other processes.

Anti-corrosion steel pipe is a specially treated steel pipe designed to prevent or slow down corrosion caused by chemical or electrochemical reactions during transportation and use. ‌ Anti-corrosion steel pipe combines the strength of steel and the anti-corrosion performance of anti-corrosion materials by forming an anti-corrosion coating on the surface of the steel pipe or using anti-corrosion materials, thereby effectively extending the service life of the steel pipe and ensuring its safe and stable operation in harsh environments. ‌

Carbon steel plate is a type of material that is used in large quantities. It is divided into ordinary low carbon steel plate and special steel plate, including low alloy high strength steel and corrosion resistant and heat resistant composite steel plate. Ordinary low carbon steel plate is divided into cold rolling and hot rolling. Cold rolled steel plate has good surface quality and precise thickness and size, and is mostly used to manufacture car bodies. Hot rolled plates are mostly used to manufacture frames.

Silicon steel is an iron alloy containing silicon that is mainly used to make the cores of motors, generators and transformers. ‌It has excellent magnetic properties with high magnetic permeability and low iron loss value, which can significantly improve the efficiency of power equipment and reduce energy consumption. ‌

Line pipe is a pipe used to transport liquid and gaseous fuels such as petroleum, natural gas, water and oil. ‌It is mainly transported by underground burial and is mainly used in the oil and gas industry. Line pipes can be divided into two types: seamless welding and seam welding according to different connection methods. Seamless welded line pipes have good air tightness but poor flexibility and are suitable for long-term fixed routes; while seam welded line pipes can be changed in direction by plasma cutting machines, but have poor air tightness. ‌

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made of low-carbon structural steel or low-alloy structural steel strip rolled into a tube blank at a certain spiral angle, and then the tube seam is welded. ‌ This structure makes it possible to produce large diameter steel pipes using narrower strips. The specifications of spiral pipes are usually expressed in terms of outer diameter and wall thickness.

Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin on the surface.
It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the
zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.
