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.

DX51D material is a mild steel galvanized layer for steel products. Specifically, DX51D is a steel grade characterized by its cold-formed bending and profiling qualities.

The Z150 in the DX51D Z150 galvanized coil is the actual coating name. The manufacturer describes the DX51D Z150 material as a mild steel galvanized layer for steel products. Specifically, DX51D is a steel grade characterized by its cold-formed bending and profiling qualities.

The material of DX52D galvanized coil is a non-ferrous alloy composed of zinc as the matrix. 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.

DX53D galvanized coil is a commonly used construction steel with a wide range of material properties and applications, excellent corrosion resistance and good processing performance. In the construction industry, this material is widely used in roofs, walls, floors and other parts that need to resist atmospheric corrosion.

The Z275 galvanized steel coil is kind of a double-sided galvanized carbon steel. This is produced by a metal coating process that passes cold rolled coils through a bath filled with molten zinc.

Z120 is the coating name, which means that the coating thickness on both sides is approximately 120g/㎡ or 36g/㎡ (three-point test). Z120 grade galvanized coil is coated with zinc to make it more durable.

Galvanized steel coils are covered with a zinc coating to provide corrosion resistance. G40 galvanized steel coil is a galvanized layer name or A653 standard specification specified in the hot-dip coating process galvanized or zinc-iron alloy steel coil requirements.

G60 is the coating grade of steel coil after continuous hot dip plating process. G represents the "galvanized" or galvanized layer of the product. The number 60 refers to the weight of the zinc around the steel coil or the thickness of the entire double-sided coating.
