Note: Oil-canning is not considered grounds for rejection of any panel system. Oil-canning can occur in any panel with wide flat sections. Heavier gauge, embossing, striations, flatter sub-frame systems and support from a solid sub-deck can all help to minimize oil-canning.

Description: A unique feature of this panel is a vertical leg that is a side joint that is mechanically seamed with an electric seamer for a weather tight finish. This panel features concealed clips and easy to handle 16" wide panels custom cut to the desired length. This panel can be installed directly over purlins or bar joists. It does not require a solid substructure for support. This roof system has several different UL90 construction numbers.

Gauge: 24 (standard) with 22 gauge available on request

Length: Maximum 50' (standard), other lengths are available as special requests

Dimensions: 12" or 16" wide by 2" high

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

Finish: Galvalume

Manufactured: Multiple facilities within NCI

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.

Limitations: Recommended for roof slopes of 1/2:12 or greater. Oil canning is not a reason for rejection.
