Properties of Cold-Formed Steel:
Ductility: Cold-formed steel exhibits high ductility, meaning it can deform without breaking easily.
Yield Strength: The yield strength refers to the minimum force required to cause permanent deformation in the steel.
Ultimate Tensile Strength: The ultimate tensile strength represents the maximum force the steel can withstand before breaking completely.
Elastic Modulus: The elastic modulus describes the steel's ability to return to its original shape after being deformed.
Shear Modulus: The shear modulus represents the steel's ability to resist shearing deformation.
Density: Cold-formed steel is denser than other metals, making it slightly heavier.
Sections of Cold-Formed Steel:
Rectangular Sections: These sections are the most common and consist of two flat sheets of steel bent into a rectangle.
Channels: Channels are formed by bending rectangular sections into a U-shaped cross-section.
Angles: Angles are formed by bending steel into a shape with two or more corners.
Circles: Cold-formed steel circles are formed by rolling a sheet of steel into a circular shape.
Shapes with Holes: Holes allow for the removal of material and variation in the design.
Examples:
A cold-formed steel beam may have different properties depending on its thickness.
Channels in a steel frame provide increased flexibility and load-spreading capacity.
Angles are often used in cold-formed steel panels for roofing and siding due to their stability and durability
