Quonset Doors

1 Have an existing Quonset hut - the doors are the big sliding metal split doors. Want to replace with still same size door but need one that I no longer need to pull on to open - as they are heavy and very cumbersum. Wondering if this type of Schweiss hydraulic door would help us and be more suitable. Thank you.

3 I am looking for a door for a round Quonset. Currently it has two miserable sliding doors. The opening is 20 feet wide by 14 feet tall. I am interested in the most cost effective bifold door solution.

4 I have a Behlin Quonset I'm looking for a bifold or hydraulic quonset door with a freestanding header.. The hole size is 23'9" x 14'6". I like the Schweiss strap style best and I need a man door. Interested in pricing.
