Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes.
Hot rolled carbon steel pipe is 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, geological steel pipe and other steel pipe.
Cold rolled (dial) carbon steel pipe in addition to 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. The outer diameter of hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless pipe can be up to 6mm, and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm, and the wall thickness is less than 0.25mm

Steel strip refers to the conveyor belt made of carbon steel as the traction and carrying component of the belt conveyor, and can also be used to bind goods; It is a kind of narrow and long steel plate produced by various kinds of rolling enterprises in order to meet the needs of different industrial sectors to produce various kinds of metal or mechanical products.
The strip, also known as strip steel, is within 1300mm in width, and the length varies slightly according to the size of each roll. Strip steel is usually supplied in rolls, with high dimensional accuracy, good surface quality, easy processing, material saving and other advantages.
According to the material used, the steel strip can be divided into ordinary steel and high quality steel. According to the processing method, there are two kinds: hot rolled steel strip and cold rolled steel strip

Round bars are divided into three types: hot rolled, forged and cold-drawn. Hot rolled round bars are available in sizes from 5.5-250 mm. Among them: 5.5-25 mm small round steel is mostly supplied in straight strips in bundles, often used as steel bars, bolts and various mechanical parts; Round bars larger than 25 mm are mainly used to manufacture mechanical parts, pipe blanks for seamless steel pipes, etc

Tin plating coil, is the common name of electroplated tin thin steel plate, English abbreviation for SPTE, refers to the cold rolled low carbon thin steel plate or steel strip coated with commercial pure tin on both sides. Tin mainly plays a role in preventing corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solder resistance and beautiful appearance of tin in a material with corrosion resistance, non-toxic, high strength and good ductility characteristics

Tinplate (commonly known as tinplate) is a surface coated with a thin layer of metal tin steel plate. The tin plate is the low carbon steel rolled into about 2mm thick steel plate, after pickling, cold rolling, electrolytic cleaning annealing, leveling, cutting processing, and then after cleaning, electroplating, soft melting, passivation treatment, oil coating shear into the tin plate finished products, the tin plate used for high purity tin (Sn> 99.8%). The tin layer can also be coated by hot dip plating method. The tin layer obtained by this method is thicker, the amount of tin is large, and there is no need for purification after tin plating

Ordinary aluminum alloy pattern plate: aluminum alloy pattern plate processed with 1060 aluminum plate as the plate base, can adapt to the ordinary environment, the price is low. Usually cold storage, floor, outer packaging use this pattern aluminum plate.
2, aluminum alloy pattern plate: With 3003 as the main raw material, this kind of aluminum plate is also called rust-proof aluminum plate. Its strength is slightly higher than that of ordinary aluminum alloy pattern plate, and it has certain rust-proof performance, but its hardness and corrosion resistance are not up to 5000 series pattern plate. Therefore, this product is applied in the aspects of rust prevention with less strict requirements, such as truck models and cold storage floor.
3.Aluminum magnesium alloy pattern plate: It is processed with 5000 series aluminum plate such as 5052 or 5083, which has good corrosion resistance, hardness and rust resistance. Usually used in special places, such as ships, carriage lights, wet environment, this kind of aluminum plate hardness is high, has a certain bearing capacity
