Product Introduction

SGCC Steel is a galvanized steel material commonly used in construction, vehicles, home appliances, and daily necessities in China. Its chemical composition and mechanical properties are regulated by the standard JIS G 3302-2019.


SGCC steel material is hot dip zinc coated steel for commercial quality. The first letter “S” stands for steel, while “G” indicates galvanization. The third letter “C” refers to cold-rolled steel. That is, the base metal is CR steel. And the fourth letter “C” means commercial quality.


The biggest advantages of coated steel plates are excellent corrosion resistance, paintability, decoration and good formability.


SGCC steel has the following general characteristics:


1)Advantages:Excellent corrosion resistance,Strong weather resistance,Bright surface and beautiful appearance,Easy to process,Economical solution


2)Excellent Plasticity: SGCC steel exhibits good plasticity, allowing it to be formed into various shapes and structures without fracturing.


3)Wide Application: Because of its high corrosion resistance, SGCC steel is an ideal material for outdoor applications. It is the main material in building materials, light industry, agriculture, transportation and other industries.



SGCC has a wide range of applications in various industries due to its good mechanical properties and affordability. Some common applications of SGCC include:


1) Hot-dip galvanized products are widely used in construction, home appliances, vehicles and ships, container manufacturing, mechanical and electrical industries, etc., involving almost every field of clothing, food, housing and transportation.


2)SGCC steel is versatile in numerous fields including power towers, railways, containers, lampposts, steel structure, and light industry.


3) SGCC steel is commonly utilized as construction materials such as corrugated sheets, roofing tiles, pipelines, fencing, etc.


4) SGCC steel also finds its use in the manufacturing of automotive parts, for example, body panels, car ceilings and chassis components.


5) SGCC steel is also very suitable in the furniture industry, such as lampshades, desks, bookshelves and other commodities.


6) Railway Vehicles: SGCC steel is also used in the manufacturing of railway vehicles, including railcar bodies, underframes, and structural components.


Classification By Size

SGCC steel coils and sheets are available in various thicknesses, ranging from 0.25 mm to 3.2 mm.

The length is generally 2440mm, 2000mm, 3050mm, 4000mm, 3000mm, and the thickness is distinguished by cold rolling and hot rolling. Cold rolling mainly has thickness 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm. The main thickness of hot rolling is 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm, and the width is generally 1000mm, 1219mm, 1500mm.Please contact customer service for general specifications.

Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels. Application range: (1) After annealing, it is processed into ordinary cold rolling; (2) The galvanizing unit with pre-annealing treatment device processes galvanizing; (3) Panels that basically do not need to be processed.

Hot-rolled coils (in the form of flat plates or coils) generally have a thickness of 2.0-13.5mm, of which the price of 2.0-3.0mm hot coils gradually decreases from thin to thick; most steel mills have a basic price of 3.1mm-13.5mm Equivalent, the price of 3.1-4.0mm and 9.5mm-13.5mm hot plate coils in some manufacturers and markets may be higher than the price of 4.0mm-9.5mm plates. Hot plate coils represent products with a thickness of 5.5mm. Under normal circumstances, the price of flat plates is slightly higher than the price of coils.
