PPGI (Prepainted galvanized steel)is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than galvanized steel sheets.
The base metal for PPGI consist of cold-rolled steel, Hot dip galvanized steel, electro-galvanized steel and hot dip galvalume steel .The coating material is as following: Polyester, Silicon modified polyester, Polyvinylidene fluoride, high-durability polyester ,etc.

Color-coated corrugated board, also called profiled board, adopts color-coated steel sheet, galvanized sheet and other metal sheets to be rolled and cold-formed into a profiled board with various wave shapes. It is suitable for industrial and civil buildings, warehouses, and special buildings. , Roof, wall and interior and exterior wall decoration of large-span steel structure houses.

Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective anti-corrosion method that is often used. About half of the world’s zinc production is used in this process. Galvanized steel sheet is to prevent corrosion on the surface of the steel sheet and prolong its service life. The surface of the steel sheet is coated with a layer of metallic zinc. This kind of galvanized steel sheet is called galvanized sheet.

Color-coated corrugated board, also called profiled board, adopts color-coated steel sheet, galvanized sheet and other metal sheets to be rolled and cold-formed into a profiled board with various wave shapes. It is suitable for industrial and civil buildings, warehouses, and special buildings. , Roof, wall and interior and exterior wall decoration of large-span steel structure houses.

The width of the sheet is 500~1500 mm; The width of the thickness is 600~3000 mm. Thin Coils are classified by steel types, including ordinary steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet, etc. According to the professional use, there are oil drum with board, enamel with board, bulletproof with board, etc. According to the surface coating points, there are galvanized sheet, tin Coil, lead Coil, plastic composite steel Coil.

Most of the 304L stainless steel sheets are shipped in whole rolls, mainly for the convenience of transportation. In the hands of the stainless steel processing factory, in order to facilitate processing and manufacturing, these 304L stainless steel coils will be flattened by professional stainless steel flattening equipment, just like the whole roll of toilet paper, divided into pieces. The 304L stainless steel plate after opening is called “opening plate”.

201 stainless steel, has a certain acid resistance, alkali resistance, high density, polishing no bubble, no pinhole and other characteristics, is the production of all kinds of watchcase, watchband bottom cover quality materials.
Mainly used for decorative pipe, industrial pipe, some shallow stretching products.

After 304, SUS316 is the second most widely used steel grade, mainly used in the food industry and surgical equipment, adding molybdenum to obtain a special structure that is resistant to corrosion. Because of its better resistance to chloride corrosion than 304, it is also used as “marine steel”. SS316 is usually used in nuclear fuel recovery units. Grade 18/10 stainless steels generally also meet this application level.

It is used in field open-air machines in chemical, coal and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant parts of building materials and parts with difficult heat treatment.

304 stainless steel is a very common stainless steel, also known as 18/8 stainless steel in the industry. Its corrosion resistance is better than 430 stainless steel, with high corrosion resistance and good processing performance, so it is widely used in industry, furniture decoration industry and food and medical industry, such as: some high-grade stainless steel tableware, bathroom kitchen utensils.

The yield strength of 2205 duplex stainless steel is more than double that of ordinary austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more affordable than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F temperature range. For applications outside this temperature range, this alloy may also be considered, but there are some limitations, especially when applied to welded structures

202 stainless steel plate is a metastable austenitic stainless steel. Its national standard model is 1Cr18Mn8Ni5N. It has high strength, toughness, high wear resistance and large work hardening. 202 stainless steel is widely used in architectural decoration, hotel facilities, shopping malls, glass handrails, public facilities and other places. It is welded by high-precision automatic pipe-making equipment, through self-etching welding, rolling and forming, without any metal filler, filled with gas protection (inside and outside of the pipe) and welded. The welding method is TIG process, and online solid solution eddy current is used. flaw detection.

201 stainless steel is a 200 series austenitic stainless steel developed by replacing nickel elements with manganese, nitrogen and other elements. It has good corrosion resistance and hot and cold working properties, which is enough to replace the previous use in indoor and inland cities. 304 stainless steel products used in low corrosive environments.

Stainless steel 904L coils are extremely durable and withstand extremely high pressures. It is a low sulfur coil. With moderate corrosion and crevice corrosion resistance, SS 904L Coils is a super austenitic alloy designed for a wide range of applications in oxidizing and reducing environments. It has a thick frame with added molybdenum and copper to resist all chemical attack and a smooth finish, weatherproof and more. 904L stainless steel pipe is the first choice in the production of phosphoric acid, sulfuric acid, metal pickling, gas scrubbing, seawater, brackish water, heat exchangers, condensers, oil and gas exploration, seawater desalination plants, etc. These coils have a variety of quality features and perfect dimensional accuracy.

As an important material in aerospace and chemical industries, 310S heat-resistant steel is widely used in high temperature environments. High temperature oxidation is the most common and most important form of corrosion damage at high temperature. Therefore, the research and development of new materials with high temperature oxidation resistance has far-reaching significance for my country’s aviation industry, chemical industry and national defense. Austenitic heat-resistant stainless steel 310S (0Cr25N i20) is a high chromium nickel austenitic stainless steel

304 stainless steel is one of the most widely used chromium – nickel stainless steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other thermal processing, no heat treatment hardening phenomenon (use temperature -196℃ ~ 800℃).
