Double-lock standing seam
Double Lock
Quiet lines,
serious protection.
For double-lock standing seam, we use McElroy coil stock and GreenCoat PLX Pural BT color-coated steel. It is a premium concealed-fastener system where the coil, the forming, and the finished double-lock seam all work together to create a clean roofline built for Maine weather.
Talk through your roofThe seam is
the system.
Double-lock panels create a durable, low-profile finish when the roof is laid out and locked correctly. We treat the roof as a complete system—from the underlayment to the final hand-finished edge.
Product description
McElroy coil +
GreenCoat PLX Pural BT.
SSAB describes GreenCoat PLX Pural BT as a premium color-coated steel developed with tinsmiths for standing-seam work. Its formability supports tight folds, while the coating is designed for weathering, UV resistance, and corrosion resistance. McElroy’s standing-seam systems use concealed fasteners and mechanically seamed panels; we form and double-lock the panels to fit the roof, then finish the transitions and penetrations by hand.
