BattenLok® Roof

Home/Products/Roof Panels/BattenLok® Roof

A unique feature of the BattenLok HS® panel is a vertical leg side joint that is mechanically seamed with an electric seamer for a weathertight finish. This panel features concealed clips and easy to handle 16″ or 12″ wide panels custom cut to the desired length. BattenLok HS® HS can be installed directly over purlins or bar joists. It does not require a solid substructure for support. This roof system has several different UL® 90 construction numbers.


  • 24 gauge (standard)
  • 22 gauge


  • Maximum 50′ (standard), other lengths are available as special requests


  • 16″ wide and 2″ high (standard)
    12″ also available


  • Galvalume Plus®
  • Signature® 200 Colors
  • Signature® 300 Colors


  • Recommended for roof slopes of ½:12 or greater. Oil canning is not a reason for rejection.


  • A choice of concealed fastening clips is available for this panel system including UL® rated clips. These clips hold the panel firmly in place without unsightly exposed fasteners. Each clip system offers the ability to accommodate thermal movement.


  • This panel is a structural panel that spans up to five feet on purlins, or can be used as an architectural panel over solid deck. This flat panel is designed with striations as an option to minimize oil-canning. It is designed to meet the ever-changing specifications and other industry codes.


  1. Factory applied mastic inside of female leg of panel is standard
  2. Swaged end laps
  3. Heavier gauges, striation and embossing (optional)
  4. Roof runs without end lap panels may be erected from either direction
  5. Roof to wall transition
  6. 80% less exposed fasteners than traditional side lap panels and all-fasteners are long life
  7. The side lap has been tested for air infiltration and water penetration under ASTM E283 and E331 methods
  8. Vertical Leg
  9. Insulated with thermal blocks
  10. High or low floating clips available
  11. High or low fixed clips available
  12. Panel available in Signature® 300 and Signature® 200 Colors
  13. UL® 90
  14. Panel has striations


  1. Insures watertightness and
    easier erection
  2. Improves erection and
    enhances watertightness
  3. Minimizes oil canning
  4. Flexible and convenient erection
  5. Creates a trimless eave
  6. Increases weathertightness and improves appearance
  7. Minimizes air infiltration and water penetration and enhances acceptability among specifiers
  8. Better transition to hip, valleys, and
    roof openings
  9. High energy efficiency system
  10. Allows roof to expand and contract maximizing weathertightness
  11. Provides of varying insulation thickness
  12. 25 year finish warranty
  13. Reduces insurance costs
  14. Helps with oil canning

BattenLok® – Section Properties

Properties Notes:

  1. All calculations for the properties of
    BattenLok HS® panels are calculated in accordance with the 2001 edition of the North American Specification For Design Of Cold-Formed Steel Structural Members.
  2. Ixe is for deflection determination.
  3. Sxe is for bending.
  4. Maxo is allowable bending moment.
  5. All values are for one foot of panel width.

Allowable Uniform Loads 
In Pounds Per Square Foot – 16″ Panels

Allowable Uniform Loads Notes:

  1. Allowable loads are based on uniform span lengths and Fy = 50 ksi.
  2. LIVE LOAD is limited by bending, shear, combined shear and bending and web crippling.
  3. Allowable loads consider a maximum deflection ratio of L/180.
  4. The weight of the panel has not been deducted from the allowable loads.
  6. Please contact manufacturer or manufacturer’s website for most current allowable wind uplift loads.
  7. The use of any field seaming machine other than that provided by the manufacturer may damage the panels, void all warranties and will void all engineering data.
