Concrete frame construction is probably the most common kind of construction system used in the world today. As the name suggests, this has a skeleton of concrete, that is covered in a skin. The skin can be made of brick, aluminum or glass, and is attached to the outer surface of the building.

A concrete frame building is usually built from reinforced concrete. This means that steel rods are tied into the concrete before it sets. The steel rods provide strength and rigidity to the structure and act as a skeleton for support of the other elements like doors and windows.

The concrete is poured into forms that are made specifically for each shape or size of wall section so that they fit tightly together when they dry. This gives them added strength against breaking apart due to earthquakes or other natural disasters such as tornadoes or hurricanes which can cause lots of damage because they’re so strong!
