Description

Technical Field

[0001] The utility model relates to the technical field of cold-bent steel pipes, in particular to a bending-resistant cold-bent steel. Background Art

[0002] Cold-formed steel, also known as steel cold-formed profiles or cold-formed profiles, refers to steel of various cross-sectional shapes and sizes made by bending hot-rolled or cold-rolled strip steel as blanks. It is the main material for making light steel structures, with various ultra-thin, reasonably shaped and complex cross-sections that cannot be produced by hot rolling. There are many varieties of cold-formed steel. According to the cross-sectional shape, there are open, semi-closed and closed ones. The main products include cold-formed channel steel, angle steel, C-shaped steel, Z-shaped steel, cold-formed corrugated steel plate, square tube, rectangular tube, electric welded special-shaped steel pipe, rolling door, etc.

[0003] As a type of cold-bent steel, C-shaped steel has many advantages. However, the wall thickness of traditional C-shaped steel is uniform. In special application scenarios, such as when C-shaped steel needs to be placed horizontally to bear weight, it is easy for C-shaped steel to bend when it is used too heavy because there is no special anti-bending load-bearing mechanism inside. Further improvement is needed for this problem. Summary of the invention
