SAFE-Lok Panels By Safeway Steel Buildings



A metal standing seam roofing product attached to sub-framing using a variety of concealed, interlocking clips that provide for minimum panel penetrations. This panel can be used on new construction as well as retrofit on existing structures. This panel design provides a high degree of weathertightness and has been tested by independent laboratories in accordance with ASTM E283 and E331 (for air infiltration, water penetration, and wind uplift).


24 (standard), 22 (available on special request)


50′ maximum standard and longer lengths available by special request.


24″ wide by 3″ high


Concealed fastening system. The clips are available as floating or fixed. Two different clip heights are available to allow for thermal blocks.


Galvalume® and Signature® 300 optional


New and retrofit applications


Recommended for roof slopes of 1/4:12 or greater. When using the fixed clip we recommend for double slope buildings 200’ wide or less and single slope buildings 100’ wide or less. (May vary upon extreme weather conditions.) Oil-canning is not a reason for rejection.


Oil-canning is not considered grounds for rejection of any panel system. Oil-canning can occur in any panel with wide flat sections. Heavier gauge, embossing, striations, flatter sub-frame systems and support from a solid sub-deck can all help to minimize oil-canning.

  • Optional weathertightness warranty
  • Factory notched at both ends with pre-punched holes
  • End laps have a 16 gauge backup plate with pre-punched holes
  • High or low clips
  • UL 90
  • 80% less exposed fasteners than traditional side lap panels and all-fasteners are long life

  • Specially designed to seal out the elements.
  • Contributes to the system’s weathertight construction and ease of erection.
  • Severe weathertightness and additional customer confidence
  • Field installation can commence or finish from either end of building or on both sides simultaneously
