Shandong Rigang Supply Chain Management Co.,Ltd.  Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and anti-rust effects. The main method used now is hot-dip galvanizing.
The production process of hot-dip galvanized sheet mainly includes: raw sheet preparation → pre-plating treatment → hot-dip galvanizing → post-plating treatment → finished product inspection, etc. According to the habit, it is often based on the pre-plating treatment method.

Hot rolled steel coils have many advantages. First of all, it has higher strength and hardness, which can withstand greater load and pressure. Secondly, due to the heat treatment, an oxide skin layer is formed on the surface, which can effectively prevent corrosion and rust. In addition, due to the advantages of high production efficiency and low cost, hot rolled steel coil has become the main material in many industries.

The hot-rolled steel plate products produced by have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels.

Cold rolled steel coil is made from hot-rolled steel coil as raw material, which is subjected to acid washing to remove oxide skin and then subjected to cold continuous rolling. The finished product is rolled hard coil. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coil increase, and the toughness and plasticity index decrease. Deep processing requires annealing treatment.

Cold rolled steel plate is the abbreviation for ordinary carbon structural steel cold rolled plate, also known as cold rolled plate. Cold rolled steel plates are hot-rolled steel strips of ordinary carbon structural steel, which are further cold rolled to produce steel plates with a thickness of less than 4mm. Due to the fact that rolling at room temperature does not produce oxide scale, the cold plate has good surface quality and high dimensional accuracy. In addition, annealing treatment results in better mechanical and technological properties than hot-rolled thin steel plates. In many fields, especially in the field of home appliance manufacturing, it has gradually been used to replace hot-rolled thin.

Galvanised steel coils are widely used in the following industries:

In the construction industry: to manufacture structural elements low-rise construction, light steel thin-walled structures, sandwich panels, lining of heat pipelines and various heat insulation, conditioning systems, metal roof shingle, profiled sheeting, culvert pipes, cladding of entry doors, elevators, reinforcement profiles for PVC windows and plastic doors, European-type fasteners for plasterboards, etc

Galvanized steel plate is a thin sheet of metal coated with zinc to prevent corrosion on the surface of the steel plate and extend its service life.

Color steel coil(PPGI&PPGL),PPGI&PPGL in our daily life, is called color coated coil or color coated steel plate. It is a chemical transfer process that makes the strip steel that is continuously degreased on the production line go through phosphating and other chemical transfer processes. Finally, the strip steel coated with organic paint is baked at high temperature to make products. Generally, the surface of this kind of steel plate has a relatively bright color. We also call this kind of steel plate and color steel plate and color steel plate,painted board,PPGI&PPGL.

Corrugated plate is also called profiled plate. It adopts color coated steel plate, galvanized sheet and other metal plates to be rolled and cold-formed into various corrugated profiled plates. It is suitable for industrial and civil buildings, warehouses, and special buildings. , The roof, wall and interior and exterior wall decoration of large-span steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fire resistance, rain resistance, long life, and maintenance-free. It has been widely promoted and applied.
