Behlen ZL-16™ / SurLock

Architectural Standing Seam Roof System
ZL-16 metal roof panel

Roofing with Curb Appeal

Why builders, architects, and building owners choose ZL-16™/ Surlok:

  • Accommodates all three roof zone loads with two seaming profiles, Triple-Lock™ and Quadri-Lock™, achieved using a mechanical seamer. 
  • This attractive metal roof system combines clean design with performance and code compliance.  
  • Great roof selection for steeper pitch applications when the roof system is more visible and add to the curb appeal of a facility.
  • The seam partially forms during panel placement, reducing installation time and limiting foot traffic on unseamed panels. 
  • Easy to seam, even with limited experience thanks to a large seam that keeps the seamer locked in place until the seaming process is complete. 
  • Patented floating clips allow for 3½” of thermal movement (1¾” expansion and contraction) without interfering with the sidelap seam sealant.  
  • G-90 galvanized steel clips ensure long-lasting, corrosion-resistant performance. 
  • 2” vertical ribs on 16” centers provide tremendous weathertightness capability along with excellent uplift resistance capacity for coastal and other high wind environments
  • Available in a range of colors, which are stylish and reflect more sunlight (solar energy) than traditional roofs, helping to keep buildings cooler and improve energy efficiency. View color selections here.
  • Approvals & Certifications include UL580 –Class 90 – Const. No 506, 506A & 506B for the ZL-16™ system, and Florida Product Approval – FL6617-R9 & FL42189 for Surlok™.
