Cold formed steel
Introduction
A large number of proprietary products use cold-formed steel. For example; cladding and decking, purlins and lintols. Cold-formed steel forms the basis for a number of lightweight pre-fabricated structures such as trusses, stud frame panels and portal frames.
Manufacturing processes
Components are manufactured using two different methods: roll-forming or brake pressing. The components may then be used to form larger, more complex fabricated structures
Structural performance of cold-formed steel
Cold-formed steel sections tend to be more sensitive to local buckling effects than typical hot rolled sections. Cross sections are generally stiffened to improve resistance to local buckling.
Typical applications
The range of application of cold-formed steel structures is considerable and increasing.
