The PERKA MODEL 9000 is a ROOF ONLY frame or truss system that can be used for new, retrofit or re-roof purposes. You can use this truss system on your own new block, concrete or even EXISTING wall structure. Unlike other light gauge custom ‘on the job’ made systems, the prefab and pre-engineered Perka Model 9000 offers extended bay spacing for the trusses to allow for larger spans, more flexibility for roof finish and panel systems as well as the ability to withstand high loads all with the same strength and durability of all Perka Designed models.
With Perka’s in house Engineering and design team, you can modify and customize this frame to meet virtually ANY design, load and span combinations. It can also be easily combined and married up with ANY other model to create really unique and pretty interesting designs.
The bottom cord can also be designed such as to allow you the opportunity to add bottom cord clips to attach strapping to create a covered ceiling with upper attic type space to run conduit or ductwork. Since the bays are typically spaced 10′ to 18′ apart it still allows for plenty of unobstructed space above and in between each main frame as well.
This type of frame design has been used to replace roof collapses over otherwise sound and built up wall systems, retrofitting over manure pits, spanning large distances between walls without posts or columns as well as for many remodeling uses to change a flat roof into a single slope or peaked type system. There are few limits to its possibilities, if it can be drawn into your project, it can be made and at a cost that is still very affordable!
