Steel is widely used in life. Whether it is building high-rise buildings or small items, steel and steel furniture can be seen. There are many types of steel, and different types are used on different occasions and products. The steel knowledge shared with you today is related to furniture in life or office.
When it comes to furniture, wooden furniture is the mainstream product for both living and office, but in recent years, steel furniture has sprung up and has become a popular office product in the office furniture industry. These are the new aesthetic values brought about by economic development. . I wonder if you have noticed the material column when purchasing steel furniture products. The material identification of many steel furniture is not steel but cold-rolled steel. What is the difference? The following will be popularized for you.
There are two kinds of steel plates or steel strips in the steel market, hot-rolled steel plates and cold-rolled steel plates. From the name, it can be decomposed into one is hotly processed and the other is cold processed. Although both kinds of plates can be made into furniture, they are processed into All kinds of furniture, or cold-rolled steel sheet is better.
The carbon content of hot-rolled steel sheet is slightly higher than that of cold-rolled steel sheet, which has good ductility, low hardness, and easy processing, but hot-rolled steel sheet has relatively low strength and poor surface quality, such as oxidation and low finish.
Although the hardness and strength of the hot-rolled sheet are low, the plasticity and ductility are good, and it is generally a medium and heavy plate.
Although the carbon content of a cold-rolled steel sheet is not as high as that of the hot-rolled sheet, its hardness is high. Although it is relatively difficult to process, the sheet is not easily deformed, and its strength is also high. The surface finish of the sheet is also higher than that of the hot-rolled sheet.
The cold-rolled steel plate has the characteristics of high hardness, high strength, not easy to deform, and smooth appearance, which is suitable for thin plate and stamping plate. The thickness of cold-rolled steel plates can be reduced to about 0.18mm. Therefore, in the manufacture of steel furniture, cold-rolled steel is more suitable than hot-rolled steel, and it is more popular with manufacturers, which is why the material of steel furniture is marked with cold-rolled steel.
