At what temperature does light steel framing lose its strength？

The temperature at which light steel framing begins to lose its strength is known as the critical temperature or critical point. The critical temperature for light steel is typically around 500°C (932°F) to 600°C (1112°F).

At temperatures above this range, light steel framing undergoes a significant reduction in strength and may experience a loss of load-carrying capacity. This phenomenon is known as thermal weakening or softening.

It's important for  engineers to consider the potential effects of high temperatures on light steel framing when designing buildings and other structures. In fire safety engineering, for example, calculations are often performed to assess the structural performance of steel components under fire conditions.

Keep in mind that specific steel alloys and their composition can influence the critical temperature, so it's essential to consult the material specifications and relevant standards for accurate information on the behavior of a particular type of structural steel under elevated temperatures.

Our company produces various types of light steel framing, which are highly stable and not easily deformed. If you need it, please contact us.
