Selection and use of sheet metal materials

Mar 19 , 2021

Commonly used sheet metal materials are as follows:


1. Cold rolled sheet, grade SPCC. The most basic sheet metal material has a wide range of uses. It is used as a base material for other materials and is more susceptible to rust.


2. Electro-galvanized sheet, grade SECC, is widely used in electroplating with cold plate as the base material, which is the result of chemical reaction.


3. Hot-dip galvanized sheet, brand SGCC, has a wide range of uses. It is a product of cold sheet as a base material and heated in a molten zinc solution to form a zinc layer. The production process is a physical change process.


4. Hot-rolled plate, grade SPHC, is a low-end material that is easy to rust, and the thickness is generally above 3mm. Usually used to make hinge products.


5. SD steel plate is a plate with excellent anti-rust and anti-corrosion properties. The mounting bracket of the outdoor unit of the air conditioner uses this material.


6. Stainless steel and stainless iron, typical grades SUS304 and SUS430, belong to alloy materials. Good anti-rust and anti-corrosion performance and beautiful surface. Usually used to make exterior parts, such as the door shell of a refrigerator and the cooktop of a gas stove.


7. Al-galvanized sheet seems to belong to a kind of electro-galvanized sheet, but there is a kind of metal aluminum element more than electro-galvanized sheet, so the surface is relatively smooth and beautiful, and it is often used for appearance parts, such as the back steel plate of a certain model of refrigerator.


8. Aluminum plate or aluminum alloy plate, can also be called aluminum sheet. Low density and anti-corrosion, typical products: refrigerator drain pan and evaporator fins, etc.
