(1) surface state: The surface state of galvanized sheet is different because of the different treatment methods in the coating and plating process, such as ordinary zinc flower, fine zinc flower, flat zinc flower, zinc free flower and phosphating surface. The German standard also provides for surface grades.
(2)Galvanized steel plate is coated with a layer of metal on the surface of the steel plate to prevent corrosion and prolong its service life
（3）It is divided into two kinds of galvanized sheet and galvanized sheet packing. General iron sheet packing, lined with moisture-proof paper, with iron kidneys strapped on the bracket. The binding should be firm to prevent the inner galvanized sheets from rubbing against each other.

Carbon steel tube is made of steel ingot or solid tube billet through perforation into wool tube, and then hot rolled, cold rolled or cold drawn
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 steel pipe can reach 6mm and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipe can reach 5mm and the wall thickness is less than 0.25mm.

The strip is cut into narrow strips of steel, which are then moulded into tubes.
A special welder then welds the seam together. External weld is polished.
The inner burr of the general welded pipe is not played. Internal burrs are only used for precision welded pipes.

Color coated coil is hot galvanized plate, hot galvanized aluminum zinc plate, galvanized plate and other substrates, the surface pretreatment (chemical degreasing and chemical conversion treatment), on the surface coated with a layer or several layers of organic coating, and then after baking curing products. Also because coated with a variety of different colors of organic paint color steel coil plate thus named, referred to as color coated coil.
Color coated roll has light weight, beautiful and good corrosion resistance, and can be directly processed, the color is generally divided into gray, blue, brick red, mainly used in advertising, construction, household appliances, electrical appliances, furniture industry and transportation industry.
