P-55 EI90 - Fire Steel Door

Fire steel doors are essential safety components in buildings, designed to contain fires and prevent them from spreading. They're constructed with a solid steel core and often filled with fire-resistant materials like mineral wool or foam. This construction allows them to withstand high temperatures and remain intact for a specific duration, giving people time to evacuate and minimizing property damage. These doors are commonly found in commercial and industrial buildings, stairwells, and increasingly in residential homes for added fire safety.
