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.

Our C-Lock standing seam roofing cuts the cost of lumber and labor, while making lean-to and shed roof additions easier than ever before!
With our C-Lock roofing, you can…
- Take an existing barn, garage, or house and add on faster than ever before!
- The unique self-supporting design of our C-Lock roof sheets allows them to clear greater spans than any other metal roofing product we know of. (see C-Lock span charts for details)
- Determine your ledger beam height and header height, being sure to allow a minimum of 1/2″ of rise for every 12″ of run.
- Install posts for your header beam. (posts, header, ledger, and existing building structure must be sized according the loads they will support.)
- Once posts are set, install ledger and header beams at the required height for your chosen roof slope. (4% minimum)
- Starting from the end, mark ledger and header beams according to sheet width. (In this case, sheet width is 12″)
- The first sheet to be installed should be the “starter” sheet, which has two inward facing flanges. Align it with the end of your ledger and header beams, with the end against the building. Once it is aligned, the sheet can be secured with self-tapping screws.
- Lock standard sheet to starter sheet, making sure the sheet fits evenly within your sheet width marks.
- Following the same process as the first two sheets, your new C-Lock roof will be completed in no time!
- Need more space? We have the ability to manufacture roof sheets over 40 feet long!
