Metal Roofing Panel Profile
Everlast Metals DL-150 Double-Lock Standing Seam roofing panel utilizes the proven seaming process of Mechanical Locking in conjunction with the floating action of a concealed clip assembly. This design allows for expansion & contraction caused by natural elements, providing a virtually leak proof roof with exceptional wind uplift ratings.
The panel is available in a wide variety of materials and finishes. Substrates include G-90 Galvanized Steel, Galvalume® steel, and Aluminum. All painted products are Fluropon® coated.
An optional thermally applied pre-assembly in-seam sealant is available. The minimum slope requirement is 1.5:12.

Frequently Asked Questions
Method of Application
Everlast Metals DL-150 panels must be installed in a sequential pattern. Application of an Everlast Metals approved underlayment prior to panel installation is recommended when installed over a solid substrate. Panels must be locked in the field by a mechanical seamer.
Storage Guidelines
Store Everlast panels in a dry, well-ventilated space, away from any moisture. If outdoor storage is necessary, use breathable covers like canvas or waterproof paper—avoid plastic, as it traps condensation. Keep panels off the ground, slightly inclined, and supported by wood or similar insulators. Extended exposure to sunlight can damage the protective film.
