The Use of Cold Formed Steel
Cold formed steel profiles are the main material for making light-weight steel structures, which are made of cold-formed metal plates or steel strips. Its wall thickness can not only be made very thin, but also greatly simplifies the production process and improves production efficiency. It can p...Read more -
Cold Roll Forming
Cold Roll Forming (Cold Roll Forming) is a shaping process that continuously rolls steel coils through sequentially configured multi-pass forming rolls to produce profiles of specific shapes. (1) The rough forming section adopts a combination of shared rolls and replacem...Read more -
