GI sheet is widely used in multiple fields due to its excellent corrosion resistance,high strength,and good processing performance.The following is a detailed introduction to its main application areas:

1、Construction industry

In the construction industry,gi sheet are suitable for industrial plants,warehouses,and civil buildings due to their strong weather resistance and corrosion resistance.They are mainly used as roof and wall materials,building structural components,such as manufacturing corrosion-resistant industrial and civil building roof panels,roof grilles,as well as light steel structure support frames,door and window frames,ventilation ducts,and other accessories.At the same time,its surface can be treated diversely to meet the needs of exterior wall decoration.Its high strength and corrosion resistance make it the preferred choice for protective fences and indoor partitions.In addition,gi sheet are also used as enclosure materials for corrugated walls,serving both structural support and decorative functions.Their wind resistance performance can reach the 12th level typhoon defense standard.In harsh environments such as refrigerated warehouses and chemical plants,specially treated gi sheet also exhibit excellent performance.

2、Light Industry

In the light industry,gi sheet are mainly used to manufacture household appliance casings,civilian chimneys,kitchen utensils,etc.For example,white goods such as refrigerators and air conditioners often use 0.5-1.2mm galvanized sheet as the main body of the shell,and achieve dual anti-corrosion protection through electrostatic powder coating technology.The support frame for the inner drum of the washing machine is made of high-strength galvanized steel plate stamped and formed,which can maintain fatigue strength for 50000 operating cycles in humid environments.

3、Automotive industry

In the field of automobile manufacturing,gi sheet are mainly used to manufacture corrosion-resistant parts of cars,such as doors,engine covers,roofs,floor panels,and other key parts.It not only provides the necessary structural strength,but also effectively prevents the body steel plate from being corroded by atmosphere,moisture,and chemicals through its zinc layer on the surface,ensuring the long-term service life of the body and reducing maintenance and replacement costs caused by corrosion.In addition,galvanized sheet is also used in the manufacturing of automotive interior components,such as instrument panels,door panels,seat frames,etc.Galvanized sheet is often used as the substrate to achieve a beautiful appearance and comfortable touch through processes such as spraying and coating.Meanwhile,galvanized sheet has also played an important role in lightweighting automotive components.By using high-strength galvanized sheet,the weight of the components can be reduced while ensuring their strength,thereby reducing the fuel consumption and emissions of the entire vehicle.In the field of new energy vehicles,galvanized sheet has become one of the important materials in the manufacturing of new energy vehicles due to its excellent performance advantages.It is used in the manufacturing of components such as the body,chassis,and battery pack of new energy vehicles.

4、Agriculture,animal husbandry and fishery

In agriculture,animal husbandry,and fisheries,it is mainly used as food storage and transportation,as well as frozen processing tools for meat and aquatic products.

5、Business field

In the commercial field,it is mainly used as storage and packaging tools for materials.

6、Other fields

In addition to the above-mentioned fields,gi sheet are also used in structures such as the frame of multi span greenhouses and the inner walls of offshore wind power towers.The former uses G550 high-strength galvanized steel with a yield strength of 550MPa,which can achieve a span of 8 meters without column support structures;The latter uses thick zinc layer galvanized sheet(zinc layer 275g/㎡),which can resist corrosion in marine atmospheric environment for 15 years.In addition,with the continuous breakthroughs in material technology,the application of gi sheet in emerging fields such as photovoltaic brackets and 5G base stations is also constantly expanding,promoting the comprehensive improvement of anti-corrosion technology standards in various industries.
In summary,gi sheet play an indispensable role in industrial production due to their excellent performance and wide range of applications.
