I have an above ground deck 14' (joist length) x 20' wide.

Customer Question

I have an above ground deck 14' (joist length) x 20' wide. It currently has 3 posts (6'x6')about 8' apart supporting the beam. The beam is a 4" x 10" with a span of 20'. I want to remove the center post. A chart beam would indicate with that span I would need either an engineered beam or a steel beam. Correct? It was also suggested that I might put a steel faceplate (3/4" x 10") on the existing beam. Would that work?

3/4" flitch plate will not work for that beam. You need a bigger beam.
