Mine supporting steel has good stability, reasonable structure, high strength and good rigidity. The unit weight is lighter, usually it is used for supporting in coal mine tunnel and roadway.
After being set state load, optimized timbering adds support yielding deformation, increases the load-carrying ability and improves the effect of controlling the surrounding rock.

SAE 1006/Q195 Aluminum melting cathode electrowinning is used for electrolytic aluminium factory, the low carbon steel has good electrical conductivity. To produce cathode collector bar of electrolytic aluminum is a strict process, because the electrowinning system is heavy DC current, the electroconductivity will decide the cost of Aluminum, so it must have very good electroconductivity, to save power consumption and raise the electrolytic efficiency.
