​Stainless steel is a steel alloy with increased corrosion resistance compared to carbon/alloy steel.
Common alloying ingredients include chromium (usually at least 11%), nickel, or molybdenum. Alloy content often is on the order of 15-30%.
Common applications for stainless steel include food handling/processing, medical instruments, hardware, appliances, and structural/architectural uses.

Hot-dip galvanized steel sheet. The thin steel sheet is immersed in a molten zinc tank to make a layer of zinc thin steel sheet adhered to its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a plating tank with molten zinc to make a galvanized steel sheet;
Electro-galvanized steel sheet. This galvanized steel sheet made by electroplating has good processability. But the coating is thin and the corrosion resistance is not as good as hot-dip galvanized sheet;

Galvanized coil, the thin steel sheet is immersed in a molten zinc tank to make a layer of zinc thin steel sheet adhered to its surface.
It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a plating tank with molten zinc to make a galvanized steel sheet; alloyed galvanized steel sheet. This steel sheet is also made by hot dip method, but after leaving the tank, it is immediately heated to about 500℃ to form an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weldability.

Carbon steel, on the other hand, has far lower chromium levels, and is instead a carbon-iron alloy with only a few other materials, if any, as part of its makeup. As a result, it can be referred to as ‘low-alloy’ steel. Both stainless steel and carbon steel feature this basic composition, but carbon steel can be defined by its carbon content. This is normally around 2-2.5%, however this often varies. Though susceptible to rust unlike stainless steel, carbon steel is often cheaper and has its own varying mechanical properties based on carbon content.

Through electrolytic galvanizing, a uniform and dense zinc layer is finally formed on the surface of the steel, but the mechanical properties of the material are still maintained. Electrogalvanized steel is usually sold in coil or sheet form. EG coil is a kind of material that can be cut, slitted and profiled for other purposes. The steel grade of galvanized steel consists of base metal grade, galvanized (E), galvanized layer type and weight. The electro-galvanized products based on SPCC, SPCD, SPCE, SPCF and SPCG are named SECC, SECD, SECE, SECF and SECG respectively.

Color Coated Galvanized Roof Sheet PPGI Description
PPGI is a galvanized color-coated steel material. The coated steel sheet is subjected to surface chemical treatment, and then coating is applied and then baked. It has the mechanical strength and easy formability of steel plates, as well as the good decorative properties and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time. PPGI is widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.
