The length of this steel rail is 500 meters long and welded from 5 100 meters of steel rail. The welding joint has to be derusted, hot, fine grinding and testing, etc., which is to make the steel rail joint tenacious. The 100-metre rail is so hard that it can be as tough as noodles after 500 metres.
