If your products is made of Cold Rolled Steel Sheet In Coil and are used outdoors or in areas with high humidity or during the rainy season, the steel products can rust very quickly.

However, Cold Rolled Steel Sheet In Coil is good at transport, it does not need so carefully to protect them from the air, water and so on, even it could without pack.

What is the deference between cold steel and hot steel?

1. Cold plate is actually made of hot rolled plate as the main material. It is a steel plate produced through a series of cold rolling processes, and its thickness generally does not exceed 4mm. However, the specific thickness needs to be determined according to the manufacturer’s requirements. The mechanical processing performance of cold plate alone is not very good, so cold plate can be produced on the basis of hot plate.

2. The manufacturing process between them is different. The manufacturing process of hot plates is basically based on heating, while the manufacturing process of cold plates is based on cooling.

3. The characteristics between them are also different. The toughness of hot plates is relatively poor, the flatness of the surface is not high, and the price is relatively low in the market. However, the ductility of cold plates is relatively good, and the toughness is relatively strong, and the price is relatively expensive in the market.

4. There are also certain differences in the colors between them. The color of the hot plate is basically blue and black, with a relatively rough texture, while the cold plate is relatively bright silver white, with a relatively delicate texture.

5. The thickness between them is also different. The cold plate is relatively thick, while the hot plate is relatively thin. However, the specific thickness needs to be determined according to the manufacturer.
