Perka Steel Buildings
The Perka Model 8000 can probably be considered one of the premier frame shapes due to the potential for a lower profile, straight wall commercial type applications and the ease of finish. This model is most often used for stores, offices, restaurants, dealerships and the like. The 8000 highlighted by a conventional type truss system with flat bottom cord, straight leg columns (like the Model 6000) but with no knee brace obstructions. 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.
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 if desired. Since the bays are typically spaced 10' to 18' apart which still allows for plenty of unobstructed space above, the 8000 lends much easier to parapet or mansard type facades for store or business front accent and signage. The 8000 is a bit pricier than most of the other models, but it has many features that make it even easier for interior finishing that sometimes it’s worth paying a little more for the steel frame. This versatile frame can be used for just about anything your imagination can dream up!
