explain why a prefabricated steel stair is most commonly used even in buildings that are built with a reinforced concrete frame structure.

Respuesta :

Steel can support a lot of weight and is nearly five times as robust as concrete. A steel staircase may be constructed with a lot less material than a concrete one and is stronger than a concrete one.

Concrete has a high compression strength, which means it can withstand being forced together with force. The most common material used to build a stairway is concrete because of its exceptional ability to be shaped into any complex design. Timber will always be susceptible to damage from the elements and wood-eating insects, regardless of how much chemical treatment it receives. Rain and snow can quickly deteriorate a wooden staircase if it is outside.
