First, the material structure is different
There are significant differences between profiles and steel in material structure, mainly in the following aspects:
1. Different shapes:the section shape of the profile can be square, round, rectangular, etc., while the section shape of steel is usually round or square.
2. The section size is different:the section size of the profile is small and the length is relatively long, while the length of the steel is short and the cross-sectional area is large.
3. Different uses:profiles are usually used in construction machinery, automobile manufacturing and other fields, while steel is mainly used in building structures, Bridges and other fields.
Second, different production processes
There are also differences in the production process of profiles and steel, mainly in the following aspects:
1. Different production methods:The production of profiles is usually hot-rolled or cold-drawn, while the steel is often hot-rolled.
2. Different production processes:profile production generally needs to go through multiple processes such as cutting, milling, stamping, etc., while steel production is relatively simple, only one to two processes such as hot rolling can be completed.
3. Different costs:Because the production process of profiles is more complex, the cost is generally higher, and the production cost of steel is relatively low.
Three, different uses
Profiles and steel also have different uses:
1. Hainan profile wholesale is generally used in construction machinery, automobile manufacturing and other fields, such as bridge, building columns and so on.
2. Hainan steel wholesale is mainly used in building structures, Bridges and other fields, such as steel frames, steel beams, steel plates and so on.
To sum up, although profiles and steel are building materials, they have great differences in material structure, production process and use. When choosing building materials, it is necessary to choose according to the specific use and needs.
