B05 A2-3 Centria-SRS3-Roof-Tech-Data.pdf

SRS Structural Standing Seam Roof Systems are designed as true standing seam roof systems which offer high performance structural features while attaining aesthetic lines required in architectural systems. They are designed as a weather tight low-slope system for roofing in both new construction and retrofit, and provide a low maintenance, long-lasting roof for any type of building. The SRS 3 panels employ a separate field applied or factory-caulked continuous batten which provides for installation in both directions. SRS 3 panels are non-directional, which enables them to be installed left to right, right to left, or from the middle of a roof in both directions. When directional finishes are used (Micas, Metallics, etc.) one direction of installation must be held.

1. Alternate base material, panel lengths and gages may also be available. Contact CENTRIA.

2. Battens are the same gage as panel except when panel is 18 [1.19mm] gage, batten must be 20 [.91mm] for 18 [1.19mm] gage panels.

3. Available for aluminum or COE projects.

4. Embossing is non-directional.

5. Field applied webbed mastic tape is optional and is required for weather-tight warranties and field roll formed SRS3.

“Oil Canning” is an inherent part of light gage cold-formed metal products, particularly those with broad flat areas.

CENTRIA takes every precaution, as defined by MCA, to minimize the effects of oil canning. Lack of flatness or waviness due to oil canning is not sufficient cause for rejection of material.

SEAMED PANEL

• May be installed over a variety of support substrates, including open framing, steel deck, or plywood deck

• Mechanically seamed side joint with a separate continuous batten

• Concealed clip system reduces roof penetrations and includes a built-in standoff to allow for thermal movement

• SRS 3 panels may be erected from left-to-right, right-to-left, or from the middle working both directions

• Field roll forming and curving capabilities allow for longer continuous panel lengths than can be shipped on trucks

SRS 3 ROOF DESIGN FEATURES & BENEFITS

A. For information on special applications, contact your local CENTRIA Sales Representative.

B. Panel length tolerance is ±1/4” [6mm].
