These sections are cold-formed from carbon or low alloy steel sheet strip plate or flat bar in cold-rolling machines or by press brake or bending brake operations. The thicknesses of such members usually range from in. mm to about 1 4 in. mm even though steel plates and bars as thick as 1 in. mm can be .
