Ultra-Dek
  • Description
  • Features & Benefits
  • Ultra-Dek - Section Properties
  • Allowable Uniform Loads In Pounds Per Square Foot
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 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 (standard)
    22 (available on special request)

    Length

  • 50' maximum standard and longer lengths available by special request

    Dimensions

  • 24" wide by 3" high

    Finish

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


    Limitations

  • 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..

    Fasteners

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


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. 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.

Features & Benefits

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.

2. 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.

3. 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.

4. 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.

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

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

7. 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.

8. 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.

9. 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.

10. 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.

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

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

13. 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 & bending.
  3. Above 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 visit www.mbci.com for the most current wind uplift load charts.

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 coldformed 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.
