Application:

Construction field:

1. Roof and wall: As a kind of material with good corrosion resistance and certain strength, it can be used to build the roof and wall envelope structure of industrial plants, warehouses and other buildings, which can withstand the test of different climate conditions.

2. Ventilation duct: processed into components of ventilation duct system, its galvanized layer helps to prolong the service life in air humidity and other environments.

3. Building keel structure: such as part of the light indoor and outdoor keel structure, etc.

Manufacturing field:

1. Electrical equipment shell: such as distribution box, switch cabinet, control box and other shells, to protect the internal electrical components and a certain electromagnetic shielding effect, and has anti-rust function for easy use in different environments.

2. General mechanical parts: such as protective plates, casings, frames and other structural parts of various equipment.

3. Automotive industry: – Internal structural parts of the body: It can be applied in some internal structural parts that have certain requirements for strength and corrosion resistance, such as certain parts of the seat frame.
4. Hardware products: including tool boxes, shelf parts, etc.

Furniture field:

1. The main frame or support structure of metal furniture.

2. Outdoor furniture: Due to its corrosion resistance, it is suitable for furniture production in outdoor environments.

Container manufacturing:

1. Various small storage containers can be manufactured, such as storage boxes, etc.

2. In some chemical and other fields, corrosion-resistant simple containers with specific requirements can be manufactured (of course, further processing may be required for strong corrosive environments).

Agriculture field:

1. It can be used to build agricultural facilities, such as the roof and support structure of simple breeding sheds.

2. Some structural parts and shells of agricultural machinery, etc.

Physical and Chemical Properties:

Physical Properties:

1. Strength: S220GD has a certain yield strength and tensile strength, which can provide better structural support. – The yield strength is usually around 220 MPa, and the tensile strength is generally higher than the yield strength.

2. Ductile: It has a certain ductility and can undergo moderate deformation during processing and molding without cracking.

3. Hardness: Moderate hardness, which can meet the requirements of most conventional applications.

4. Density: The density is similar to that of ordinary steel.

5. Thermal Conductivity: It has a certain thermal conductivity.

6. Conductivity: It has a certain conductivity, but it is relatively poor compared to conductive materials such as pure copper.

Chemical Properties:

1. Corrosion resistance: The existence of the galvanized layer is one of its important chemical properties, which can effectively prevent the corrosion of the steel surface in the atmosphere, water and other environments. – Zinc will form a dense zinc oxide protective film in the air to prevent further oxidation reactions. – In a humid environment, zinc is more active than iron and corrosion occurs preferentially, thus protecting the iron base.

2. Oxidation resistance: The galvanized treatment of the surface can resist oxidation to a certain extent.

3. Heat resistance: Keep its performance stable within a certain temperature range, but too high temperature may affect the performance of the galvanized layer and steel.
