Ultra-Dek® is a metal standing seam roofing product attached by using a variety of concealed, interlocking clips that provide for minimum panel penetrations. This panel offers a snap together sideslap seam and saves the rental cost of mechanical electric seamer. Garco recommends installing this panel in non-snow regions. This panel can be used on new construction as well as retrofit on existing structures. This panel is designed to provide a high degree of weathertightness and has been tested by independent laboratories in accordance with ASTM E283 and E331 (for air infiltration and water penetration).

Gauge
  • 24 gauge (standard)
  • 22 gauge (available on special request)
Length
  • 50′ maximum, longer lengths available by special request
Dimensions
  • 24″ wide by 3″ high (standard)
  • 18″ also available
Finish
Limitations
  • Recommended for roof slopes of 1/4:12 or greater. Typically installed with a floating roof clip, but fixed clips can be used on gabled buildings up to 200′ wide and single slope buildings up to 100′ wide.
Fasteners
  • Concealed fastening system. The clips are available as floating or fixed. Two floating clip heights are available to allow for various thermal block and insulation thickness.
Usage
  • This panel is a structural panel that spans up to five feet purlins. It is designed to meet the ever-changing specifications and other industry codes.

Attributes

    1. DESIGN INTEGRITY
      The Ultra-Dek® roof system begins and ends in the high, reducing the risk of leakage at the rake that can occur when finishing in the low. The panel seam includes factory-applied mastic.

 

    1. FLOATING ROOF
      The Ultra-Dek® roof was designed to cope with the forces of expansion and contraction. This is accomplished by allowing the panels to freely move up and down the roof slope. Due to this design feature, the system offers no diaphragm capabilities or purlin stability.

 

    1. SLIDING CLIPS
      2″ Sliding Clips are available providing 11/4″ moverment in each direction. Sliding clips are also available in high and low versions, which provides a 3/8″ clearance or a 1 3/8″ clearance, allowing for a variety of thermal spacer and insulation thickness combinations.

 

    1. UL CLASS 90 RATING
      The Ultra-Dek® roof system has 10 different UL Class 90 construction numbers, each of which is available with several options.

 

    1. FIRE RESISTANCE RATINGS
      The roof system qualifies for use in several UL design assemblies and carries a UL “Class A” fire rating.

 

    1. SIMPLICITY
      No field seaming is required. The panels simply snap together forming a self-locking seal.

 

    1. FLEXIBILITY
      The Ultra-Dek® roof system offers welcome flexibility to the erector. Wall covering can be erected before or after the roof is installed. Panel installation is an uninterrupted procedure.

 

    1. EASE OF INSTALLATION
      The erector has the option to install each side of the roof separately or both sides simultaneously, which greatly increases the speed and convenience of erection. Being reversible end-for-end, sheets do not have to be special ordered for each side of the building. No field notching of panels at endlaps or ridge is required.

 

    1. FORGIVING SYSTEM
      The Ultra-Dek® system design allows for the roof to be finished in the “high” when an out-of-square condition or other factors cause the roof to terminate up to 4″ out of module.

 

    1. BUILDING LENGTH
      Odd, as well as even, footage buildings can be terminated at a major rib with the use of our 12″ and 18″ panel or at other odd widths by field bending the panel. Panel width availability is limited to specific fabrication facilities.

 

    1. PREPUNCHED PANELS AND COMPONENTS
      The prepunched system, combined with self-engaging back-up plates, assures panel module and speeds roof installation.

 

    1. DURABILITY
      Every unpainted panel is manufactured from Galvalume Plus®, your assurance of the manufacturer’s commitment to quality.

 

    1. COLOR AND FINISHES
      Ultra-Dek® is available in a wide variety of popular colors in three different paint systems.

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 ALLOWABLE UNIFORM 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.

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 fur ther information or guidance regarding cold-formed design practices is desired,
please contact the manufacturer.
