When the roof design specifies a curved standing seam metal roof, Curved BattenLok® is an ideal choice. The Curved BattenLok® profile is a water shedding, curved standing seam metal roof system with a 2-inch tall standing seam that is field-seamed during the installation process. Striations are standard and added for both aesthetic value and reduces oil-canning.

Curved BattenLok® may be curved to a minimum radius of 20 feet. Curved BattenLok® is a structural roofing panel and may be installed directly over purlins or joists. This curved standing seam metal roof system also may be installed over wood decks and metal decks with rigid insulation. Open framing applications eliminate costly curved deck surfaces and membrane underlayments. For large projects and/or long panels, the curving process for the curved standing seam metal roof system may best be accomplished at the job site.

Gauge
  • 24 gauge (standard)

 

Length
  • Maximum 40′-0″ (dependent on curved radius), other lengths are available as special requests

 

Dimensions
  • 16″ wide

 

Finish
  • Galvalume Plus®
  • Signature® 200
  • Signature® 300
Limitations
  • Recommended for roof slopes of ½:12 or greater. Oil canning is not a reason for rejection.

 

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

 

Usage
  • 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. Striations are standard and added for both aesthetic value and reduces oil-canning. It is designed to meet the ever-changing specifications and other industry codes.

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.
  5. THE ABOVE LOADS ARE NOT FOR USE WHEN DESIGNING PANELS TO RESIST WIND UPLIFT.
  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.
  8. This material is subject to change without notice. Please contact Robertson for most current data.

The engineering data contained herein is for the expressed use of customers and design professionals. Along with
this data, it is recommended that the design professional have a copy of the most current version of the North American
Specification for the Design of Cold-Formed Steel Structural Members published by the American Iron and Steel Institute
to facilitate design. This Specification contains the design criteria for cold-formed steel components. Along with the
Specification, the designer should reference the most current building code applicable to the project jobsite in order to
determine environmental loads. If further information or guidance regarding cold-formed design practices is desired,
please contact the manufacturer.
