Technical Field
The utility model relates to a shaped steel field especially relates to a two tough type end cold-formed steel.
Background
Cold-formed steel, also called steel cold-formed or cold-formed, is a steel section of various cross-sectional shapes and sizes made by bending a hot-rolled or cold-rolled strip steel as a blank.
Cold-formed steel is an economical section light thin-walled steel material, also called steel cold-formed section or cold-formed section. The cold-formed steel is the main material for manufacturing light steel structures. It has various very thin, reasonable and complicated cross sections which can not be produced by hot rolling. Compared with hot-rolled section steel, under the condition of the same cross-sectional area, the gyration radius can be increased by 50-60 percent, and the section inertia moment can be increased by 0.5-3.0 times, so that the material strength can be reasonably utilized; compared with the common steel structure (i.e. the steel structure made of the traditional I-shaped steel, channel steel, angle steel and steel plate), the steel can be saved by about 30-50%. In some cases, the steel consumption of the cold-formed steel structure is equivalent to that of a reinforced concrete structure under the same condition, and the cold-formed steel structure is an economic section steel.
The cold-formed steel has wide application, and is generally used for manufacturing structural parts, auxiliary parts and the like in production departments of buildings, railway vehicles, automobiles, ships and the like.
