Actually called a company today that manufacturers some of our outdoor buildings. They make literally every part other than insulation and bolts fastners. All metal panels, frames, floors and doors. Have been working with them for 8 years. Supervised their company comtractors install them. Today I called their tech support to find out how much their 10x20 units weigh empty as to figure out what size equipment I needed to move one. The tech support lady insisted over and over they only make doors. I even pointed out the website even shows they produce the entire structure. Long story short... I found the installers number and got the info.
