Prepainted Galvanized Steel Sheet
When steel components are used to make more complex finished products, they can be galvanized before the product is assembled. This is called pre-galvanizing, or "pre-galvanizing". It may also be referred to as "in-line", "continuous" or "rolled" galvanizing. Essentially, steel components (such as sheets or wires) are galvanized using an automated process before they are cut to size.
304L is one of the austenitic stainless steels with a chromium content of at least 18%, a nickel content of at least 8%, and a maximum carbon content of 0.03. 304L stainless steel is an ideal choice for various household and commercial applications, with excellent corrosion resistance, ease of manufacturing and excellent formability. Austenitic stainless steels are also considered to be the easiest to weld among high alloy steels and can be welded by all fusion and resistance welding processes.
The material of DX51D galvanized sheet is a non-ferrous alloy with zinc as the matrix and other elements. The main alloying elements are aluminum, copper, magnesium and so on. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and resistance to atmospheric corrosion. According to the manufacturing process, it is divided into cast zinc alloy and deformed zinc alloy. The commonly used casting zinc alloy is zinc-aluminum-copper-magnesium alloy, which has good casting process performance, and the cooling rate has little effect on the mechanical properties. They are mainly used in the manufacture of mechanical parts, toys, decorations and household appliances.

AZ55 aluminum zinc plated steel coil is coated with 55% aluminum zinc alloy by hot dip plating process. It has excellent corrosion resistance and can be used in various applications, such as the automotive industry, shipbuilding industry, construction industry, etc. In addition to being an excellent outdoor material, AZ55 aluminized zinc steel coil also has many other advantages. For example, it can be used for electrical equipment manufacturing or decoration, such as fences. In addition to these uses, this steel can also be used in various industrial applications because of its good mechanical properties and corrosion resistance.
Galvanized zinc coil is based on cold-rolled steel plate, which is solidified by 55% aluminum, 43.4 zinc and 1.6 silicon at 600 ℃. It combines the physical protection and high durability of aluminum with the electrochemical protection of zinc. Also known as aluminized zinc steel coil.
Type 201 stainless steel is an austenitic chromium-nickel-manganese stainless steel, which is developed to save nickel. Type 201 is a low-cost alternative to traditional Cr-Ni stainless steels such as 301 and 304. The nickel is replaced by added manganese and nitrogen. It cannot be hardened by heat treatment, but can reach high tensile strength by cold working. Type 201 is essentially non-magnetic in the annealed condition and becomes magnetic upon cold working. In many applications, the 201 type may replace the 301 type.
