Steel or concrete lintel for bi-fold patio doors?

I'm going to install 8ft bi-fold patio doors in my lounge. I have a 3ft window which is obviously coming out. What size lintel will I need and will I need a steel or concrete lintel? The length from wall to wall is 10ft, so is that the size lintel that will be needed? Thanks
