Perka Steel Buildings
The Perka Model 6000 frame is the most economical “Straight Leg” designed frame. The 6000 is a popular frame for anyone wanting economy but an easier frame to create more conventional straight-walled interior finishes. Perka’s unique pre-punched, pre-welded clip on the inside flange of their columns offers the builder/DIY an easy way to apply wall strapping that can finish BOTH outside and inside walls without having to build “another building” on the inside like you would have to do with most ALL STEEL rigid frame type applications. Except for the knee brace, which you may have to “finish” around, you can get nice clean interior lines with this model. The flat bottom cord can also allow you the opportunity to add bottom cord clips to attach strapping to create a flat ceiling with upper attic type space to run conduit or even make a load bearing area for storage if desired. Bays are typically spaced 10’ to 18’ apart which still allows for plenty of unobstructed space above. The knee brace allows you to get the benefits of straight leg designs without the bigger cost.
This structure is an economical version of the Model 8000. With a lower haunch, you can also realize higher pitches which can save you from having to go to a deeper designed more expensive roof materials. So if you want something with a conventional interior finish – like for commercial, residential or even institutional type uses – this may be a great way to have something built within a tighter budget!
