Clayton & Lambert C-Lock structural standing seam roofing is an ideal product for any new building or addition. Barns, machine sheds, run-in sheds, porches, garages, warehouses, and lean-to sheds are just a few examples of the ways this roofing has been utilized.
Originally designed for the clear-span requirements of our grain bins, this roofing eliminates the need for rafters and purlins, cutting the cost of your construction project. In addition to strength, the 225 degree, 3 inch tall C-Lock flange provides a weather tight seal.
What makes C-Lock roofing different?
- While the “span” capabilities of most roofing panels could be measured with a yard stick, a 12″ wide, 20 gauge C-Lock roof panel can span nearly 20′ between supports at 20psf snow loads. Additional panel widths and material thicknesses are available, depending on your load/span requirements.
- Due to the span capabilities of C-Lock roofing panels, the costs associated with lumber and framing are nearly eliminated.
- C-Lock roofing does not require the time consuming installation of mounting brackets, clips, or rails.
- C-Lock roofing doesn’t require any sort of “seaming” once the panels are installed. In addition to reducing installation times, this also means the roof panels can be removed or replaced, without damage, should the need ever arise.
- The underside of installed C-Lock roofing is completely smooth, leaving nowhere for unwanted wildlife to build nests.
Manufactured from 18, 20, and 26 gauge G90 galvanized steel, C-Lock roofing is suitable for the most demanding environments. Panel widths and thicknesses are matched according to your span and loading requirements. Single panels can be manufactured to lengths of over 40 feet. Should your project require more than 40 feet of panel length, the end of one panel can be slid into the next. In doing this, roof length is unlimited.
How far will C-Lock roofing span between supports?
While the clear-span capabilities of C-lock roofing depend on your intended application and local roof load requirements (consult local building codes), you can get an idea of what your area requires by looking here: US Forest Service – National Snow Load Information.
