SGCE Galvanized Steel Sheet 1mm 3mm 5mm 6mm Good Quality Steel Plate
GI steel sheets are sheets made of galvanized iron (GI). Galvanization is the process of coating iron or steel with a layer of zinc to prevent corrosion. GI sheets are commonly used for roofing, fencing, and outdoor applications due to their durability and resistance to rust and corrosion.
The thickness of GI sheets is measured in gauge, with a lower gauge indicating a thicker sheet. The most common gauges for GI sheets range from 18 to 24. The width of GI sheets typically ranges from 600mm to 1500mm.
Galvanized Steel Plate are available in two types of coating: regular spangle and zero spangle. Regular spangle GI sheets have a visible spangle-like pattern on the surface, which is created during the galvanizing process. Zero spangle GI sheets, on the other hand, have a smoother surface and do not have any visible spangle pattern.
Galvanized Steel Sheet can also be classified based on their uses. Some of the common types of GI sheets include:
1. Corrugated GI Sheets - used for roofing, wall panels, and fencing.
2. Plain GI Sheets - used for indoor applications such as ducting, electrical panels, and furniture.
3. Galvalume GI Sheets - a combination of aluminum and zinc-coated GI sheets that provide superior corrosion resistance.
4. Pre-painted GI Sheets - GI sheets coated with a layer of paint, commonly used for roofing and cladding applications.
GI sheets are available in various grades based on their strength and durability. The most commonly used grades for GI sheets are SGCC, SGHC, and DX51D.
1. Corrosion resistance, paintability, formability and spot weldability.
2. It has a wide range of uses, mainly used for parts of small household appliances that require good appearance, but it is more expensive than SECC, so many manufacturers switch to SECC to save costs.
3. Divided by zinc: the size of the spangle and the thickness of the zinc layer can indicate the quality of the galvanizing, the smaller and thicker the better. Manufacturers can also add anti-fingerprint treatment. In addition, it can be distinguished by its coating, such as Z12, which means that the total amount of coating on both sides is 120g/mm.
GI sheets have a variety of applications in different industries and sectors. Some of the common applications of GI sheets are:
1. Roofing and Cladding: Hot Dip Galvanized Steel Plate are a popular choice for roofing and cladding applications due to their durability, corrosion resistance, and strength. They are commonly used in residential, commercial, and industrial buildings.
2. Fencing: GI sheets are used for creating fences and partitions due to their strength and rust-resistance properties. They are also used as boundary walls for security purposes.
3. Automotive: GI sheets are used for manufacturing automotive parts such as body panels, roofs, and chassis due to their strength and durability.
4. HVAC: GI sheets are used in the heating, ventilation, and air conditioning (HVAC) industry for ducting, air conditioning units, and ventilation systems.
5. Fabrication: GI sheets are used in the fabrication industry for manufacturing various products such as cabinets, shelves, furniture, and other metal products.
6. Electrical: GI sheets are used for manufacturing electrical enclosure panels due to their durability, strength, and corrosion resistance.
7. Agriculture: GI sheets are used in agriculture for building poultry sheds, greenhouses, and storage units.
Overall, GI sheets offer a reliable and cost-effective solution for many applications and are widely used in numerous industries and sectors.
