1. 钢卷 The Steel Coils we supply are including Galvanized Steel Coil, Galvalume Steel Coil, Prepainted Galvanized Steel, we also called it as PPGI steel coil, PPGL steel coil, SPCC Steel, Cold Rolled Steel Coil...... The material of galvanized steel coil is always to be SGCC, SGCH, DX51D, DX52D, DX53D, S350GD etc. Galvanized Steel Coil Nowadays, the processing of producing galvanized steel is mainly using continuous galvanizing, it means immersing the steel coil in the tank of melting Zinc. A large of steel coils, like galvanized steel coil, prepainted galvanized steel coil, PPGI steel coil, SPCC steel coil, are used in automotive manufacturing, freezers, construction, ventilation and heating facilities, furniture manufacturing. The Zinc coating has become an important anticorrosion method for steel sheet, it is not only because zinc coating can form a dense protective layer on the surface of steel, but also the zinc coating has a cathodic protection effect. When the galvanized layer is damaged, it can still have the cathodic protection for the base sheet of steel. Related Products Galvanized Steel Sheet Galvanized Corrugated Roof Sheet Galvanized Steel Coil PPGI Steel Coil As for the PPGI steel coil which is use galvanized steel sheet as the base plate, then process some surface pre-treatment (chemical degreasing and chemical transformation treatment) on the galvanized steel sheet coil, it coated on the surface by a layer and several layers of organic coating and lastly proceeding by baking and curing of the product.There are a variety of different colors of organic paint color on the PPGI steel coil and it is popular among the buyers and always to be known as coating based on RAL colour code. The colour layer of prepainted galvanized steel sheet in coil is always to be PE coating, it has good adhesion and colourful, the PE coating is easy to be formed and can be used outdoors in long lifetime. With PE coating, the PPGI steel also can be moderate chemical resistance and the cost of PE coating always can be lower cost. The base sheet of the PPGI Steel Coils is galvanized steel with Zinc coating in addition to the colour layer, the added zinc layer of the based sheet plays an important role in steel surface protecting, it can prevent the steel to be rusted and this makes the service life of PPGI steel Coil is longer than common galvanized steel sheet in coil. There are many advantages of ppgi coated coil, it has beautiful surface with good corrosion prevention performance and can be directly processed, the customers can choose required painted colour from RAL code as required, the prepainted galvanized steel is mainly used in advertising industry, construction industry, home appliance industry, electrical appliance industry, furniture industry and transportation industry.

All these shall be distinguished by user requirements or working conditions. Usually, steel pipe products are classified according to the section shape, production method, pipe material, connection mode, coating characteristics and uses, etc. - The Steel Pipe can be classified Seam steel pipe and Seamless Steel Pipe based on producing methods. 图 The seamless pipes SMLS Pipe are including hot rolled seamless pipe, cold drawn seamless pipe, precision steel tube, heat expansion seamless pipe... The seamless steel pipes are produced from high quality carbon steel and alloy steel, customers can choose it based on demanded. And the Seam steel pipe, there are continuous furnace welding steel pipe, electric resistance welding steel pipe (ERW steel pipe), ARC welding pipe. Based on welding ways, there are Straight Seam welding steel pipe and Spiral welded pipe. - Based on steel grade, there are carbon steel pipe and alloy steel pipe and stainless steel pipe. - There are also different connecting ways of steel pipes, so we always classified steel pipe as common pipe with flat end and with threaded end. If for threaded ends steel pipe, our factory can always supply the pipe joints. - There are differences of pipe surface, the customers always require black steel pipe and galvanized steel pip and some PE coating and epoxy resin coating steel pipe. - We supply different steel pipes based on pipe shape. Customers always choose round steel pipe, square pipe, oval pipe, hexagon steel tube, triangle steel pipe and other irregular - shaped tubes. 3. 钢材产品 We are mainly in supplying all popular steel coil s, steel sheet, steel pipe, PPGI coil, steel plate, SPCC sheet, steel beam, steel hollow section, round bar..... Our steel products are used in a wide range of applications by various sectors and industries. Galvanized Steel Coil (GI Coil) The Steel coil is a steel product such as steel sheet that has been coiled into a roll after galvanizing process production. This process involves applying a zinc layer coating which provides an anti-rust barrier that protects the steel. The final finish is applied by an additional process of passing the steel through a high temperature, molten bath of zinc. Cold Rolled Steel Coil (CR Coil) Cold rolled steel coil and cold rolled steel sheet is produced at a room temperature – below the steel re-crystallization temperature. Manufacturing the steel using this process permits better control over thickness, dimension and the overall finish of the steel. Hot Rolled Steel Coil (HR Coil) Hot Rolled Steel Plate (HRPO) Pickled & Oiled We are supplying the hot rolled steel plates with anti wear steel grade like NM500, NM450, NM400. Our customers are using it in mining a lot. There are also hot rolled steel plate Pickled & Oiled, we called it as HRPO grade. This is is generally used in applications that require a uniform, clean and good flatness of surface – that don’t require rust protection. The HRPO is produced the same way as hot rolled steel coil with an additional pickling process conducted. This process removes scale created by the hot rolled process, after the scale is removed, an oil film is applied which protects against rust. We are mainly supplying all kinds of steel sheet, steel plate, steel profile, structural Steel, steel beams, hollow section, channel and Steel Coil, Pipe and Tube, Scaffolding Pipes, Stainless Steel, Aluminium......
