Questions & Answers
Have a Question?
-
So the floors are just spaced galvanized metal supports that the customer has to add a floor to? We have a 10’x16’ space. Also, I assume these units are 8’ tall? I forgot to check if the height is listed in the bldg description before I started writing this.
These buildings are advertised as having a metal foundation which is not a floor. The foundation kit, (steel gridwork) is similar to the floor joists of a house built on block crawlspace or basement. The house or in this case the insulated building is built up from there. The included assembly instructions show two different options for installing the floor near the end of the build process. There is an option for plywood or concrete depending on your needs.
