Rectangular tube is a hollow square section of light thin-walled steel pipe, also known as steel refrigeration bending profile. It is Q235 hot-rolled or cold-rolled strip or coil for the base material by cold bending processing and then by high-frequency welding made of square cross-sectional shape size of the section of steel.

​Seamless steel pipe is a kind of long steel with hollow section and no seams around it. It is a kind of economic section steel,seamless steel pipe according to the different cross sectional area shape can be divided into round pipe and special-shaped pipe. Using seamless steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, and save the material and processing time. Widely used in manufacturing structural parts and mechanical parts etc.

Welded steel pipe, also known as welded pipe, is made of steel plate or strip steel after crimping. The production process of welded steel pipe is simple, the production efficiency is higher, the cost is more lower, the product variety is getting richer, but the general strength is lower than seamless steel pipe.

Galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

​Stainless steel pipe are light weight and are widely used in the manufacture of mechanical parts and engineering structures. Mainly used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components

Medium thickness plates are steel plates with a thickness of 4.5 - 25.0 mm. Medium thickness plates are mainly used in construction engineering, machinery manufacturing, vessel manufacturing, shipbuilding and bridge construction. It can also be used to manufacture various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low-alloy steel plates, shipbuilding steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile beam steel plates, certain parts of tractors and welded components, etc.

The steel plate with the pattern on the surface is called the pattern plate, and its pattern is a mixed shape of lentil, diamond, round bean and oblate. The checkered plate has many advantages such as beautiful appearance, anti-skid, enhanced performance, and steel saving. It is widely used in transportation, construction, decoration, floor around equipment, machinery, shipbuilding and other fields.

For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This galvanized coil has good paint adhesion and weldability.

Color Coated sheet is also called color coated sheet, also called organic coated sheet or pre-coated steel sheet, which is based on metal coil (cold-rolled sheet, hot-dip galvanized sheet, aluminized sheet, high aluminum alloy sheet, stainless steel sheet, etc.) It is formed by coating or laminating various organic coatings or plastic films on the surface. Because it is a coil that has been surface-coated in a metallurgical plant and can be directly processed into products by users, it is also called a pre-coated coil.
