Description

Profile steel for cabinet frame

Technical Field

The invention relates to the field of cabinet frames, in particular to a section steel for a cabinet frame.

Background

Currently, the sectional materials used in the cabinet frame mainly have two structural forms, wherein the first is a cross-sectional form of bending or rolling thicker steel plates to form openings, and the second is a cross-sectional form of rolling thinner steel plates to form a closed cross-sectional form. The latter is widely used in the main structure of cabinets due to its light weight and high strength. All the frames formed by the sectional materials can better meet the requirements on the power distribution cabinet. However, the open thin-wall section steel and the closed section steel with unreasonable cut-off design are easy to distort in the subsequent production and assembly processes, so that manpower and material resources are required to be input for shaping and correcting when accessories are assembled and cabinet-spliced, and the production and delivery period are influenced.
