SDP
Structural standing-seam roof panel.
Centria SDP (Structural Design Panel) is an asymmetrical standing-seam structural panel for low-slope roofs, with outstanding resistance to wind uplift. The mechanically seamed panel spans long distances over open purlins, steel deck, or plywood, with fewer supports and no endlaps up to 48 feet.
Its structural reach also makes SDP a strong choice for equipment screens: on the Aurora Medical Center, G&L used SDP175 as a screen wall with engineered light-gauge support framing.
