Iowa Bifold and Hydraulic Doors

1 Would like just plain white door with insulation and 3 windows about 5 feet from bottom for a project in Iowa.

2 Looking for a quote on 40x20 hydraulic door for one of our projects in Iowa. Been using powerlift doors and looking at another option for this and future projects.

3 Have an older Morton building from the late 70s in Iowa the slider doors are starting to wear out. Looking at options to replace them.

4 I am working on a project in Iowa and I think your hydraulic system looks like it has everything I need. are your cylinders single acting? And would you be willing to sell just the hydraulic power unit? And how are you ensuring that the door goes up evenly? if I had a door, and one side was 10' longer then the other can your system still keep this door opening and closing evenly?
