Center Beam Installed in the middle of the house to help the foundation support the upper structure The Center Beam can be made of wood or steel

Floor Joists Center Beam Series of evenly spaced boards that run from the front of the house to the back. They work with the Center Beam to support the floor

Floor Joists & Center Beam

Subfloor • The first layer of flooring • Nailed to the Floor Joists • Usually made from plywood or particleboard
