The Perka Model 8000 can probably be considered one of the premier frames shapes as much for its potential for lower profile, straight wall commercial type applications as it is for ease of finish. It is most often used for stores, offices, restaurants, dealerships and the like. It’s 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 building ‘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 it still allows for plenty of unobstructed space above.
It also lends much easier to parapet or mansard type facades for store or business front accent and signage. It’s a bit pricier than most of the other models but it lends to many features that make it even easier for interior finishing that sometimes it’s worth paying a little more for the steel frame.
Very versatile nonetheless this frame can be used for just about anything your imagination can dream up!
