I beam for mining is a kind of section steel. It is mainly used in mine tunnels and metal stents

for support, suitable for intensive support. It is I shaped and similar to I beam. It is often made

to be door shape in mines and its legs are usually under the condition of slant-setting.

The difference between I steel for mining and I beam:1. Type: there are only 9#,11#and 12# for

I steel for mining, while types of I beam are from 8—63#. 2. Material: 16-25MnK or Q275 for

most mining I steel, and Q195-235 and Q345B(generally these two) for I beam, i.e. the

difference of common steel and manganese steel. 3. Theoretical weight: For the same or similar

specification, the theoretical weight of mining I steel is more than that of I steel. For example,

the theoretical weight of 8# I steel is 7.52kg/m, 9# mining I steel is 17.69kg/m, 12# I steel is

11.5kg/m, 12# mining I steel is 31.18kg/m. This is because mining I steel is for intensive support.

4. Place of production: Manufacturers of I beam are all over the country, while mining I steel

manufacturers are only in Tangshan, Anshan, Wuhan, Harbin, Hangzhou, of which, the steel

output from Tangshan Hebei accounts for about one third of national total output.
