CFS and structural steel differ significantly in terms of their production and framing methods. However, CFS is widely recognized for producing less waste, being light in gauge, and being cost-effective.

Structural steel is carbon-based. Increasing the steel's carbon composition means it can be adjusted to have both strength and low elasticity.

Typically, the carbon content of steel is adjusted depending on its use. Carbon also offers its own natural protection against dampness and rust.

Cold-formed steel tends to have a much lower carbon level. This is because it’s rolled at a much lower temperature than structural steel.

Research suggests that this process can make cold-formed steel up to 20% stronger than other steels.

Structural steel is hot-rolled and much thicker than CFS. As a result, structural steel is typically used for much larger construction projects than CFS, like framing out large, open spaces like industrial sites and bridges.

Sometimes, both CFS and structural steel are used together to create more robust, more efficient structures.
