1, channel steel is hot - rolled - shaped steel, U shaped steel is usually cold - rolled steel.
2. The detailed dimensions and mechanical properties of channel steel have been established into the national standard. Refer to GB/ t707-1988 for the GB file. The specifications and technical parameters of U shaped steel have not yet formed a national standard, usually according to the production needs or customer needs to make the corresponding mold to install on the rolling mill, the iron sheet volume into the required specifications of U section steel.
3. Channel steel is widely used in mechanical engineering, while U steel is only used in decoration.
