Drexel Metals
Precision roll-formed standing seam metal roofing, concealed-fastener wall panels, and ES-1/GT-1 certified edge metal systems — manufactured in the USA since 1985, now part of Carlisle Architectural Metals (CAM).
Why We Rep Them
The case for Drexel
Drexel Metals — part of Carlisle Architectural Metals (CAM), the same family as Hickman Edge Systems — delivers four related systems from one manufacturer: mechanically seamed standing seam for the structural performance institutional roofs need, snap-lock standing seam for faster, clipless installation at the same UL-rated performance, concealed-fastener wall panels that carry the same finish onto the facade, and ES-1/GT-1 certified edge metal and gutter systems that work on any single-ply commercial roof, not just Drexel's own panels. Panels are manufactured domestically and roll-formed to precision tolerances, with UL and ANSI/SPRI wind, hail, and fire testing backing the work. Profile, coating, and warranty options are confirmed per project.

Systems We Specify
Mechanically Seamed Standing Seam
Field-seamed for the buildings that can't afford to leak.
150SS, 100SS, and 200S panels mechanically seam in the field — the structural choice for demanding commercial and institutional roofs.

Drexel's mechanically seamed panels are true structural systems, field-formed with a powered seamer into single or double-fold seams up to 2 inches — built for wind, snow, and hail loads a snap-lock panel isn't rated for. Panels carry UL 580 Class 90 wind uplift, UL 2218 Class 4 hail impact, and UL 790 Class A fire ratings, with Florida Building Code approval for coastal and high-wind work.

Snap-Lock Standing Seam
The same performance, without the seamer.
100NS, 150NS, and 175S panels click into a concealed, clipless lock — faster install, same UL-rated performance as the mechanically seamed line.

Snap-lock panels eliminate metal roof clips entirely, using a self-locking nailstrip seam that installs faster than a mechanically seamed system while carrying the same Class 90 wind uplift, Class 4 hail, and Class A fire ratings. The 100NS profile ships with a 35-year non-pro-rated PVDF paint warranty and installs on slopes as low as 3:12.

Wall Panels
The same metal, turned vertical.
Concealed-fastener wall systems bring the same finish and durability of the roof to the facade.

Drexel's wall panel line spans concealed-fastener profiles — Facade HL and Facade BR, board and batten, and the DMC 164/123 series — to exposed-fastener corrugated and rib panels, in the same Fluropon PVDF or Drexlume-finished Galvalume, steel, aluminum, or copper as the roofing systems. A project can match roof and wall from a single manufacturer, with the same coating warranty backing the finish.

Edge Metal & Perimeter Systems
The edge is where roofs actually fail.
ES-1 and GT-1 certified coping, fascia, gravel stop, and gutter systems — rated for any single-ply commercial roof, not just Drexel's own panels.

Drexel's coping, fascia, gravel stop, drip edge, and gutter systems are tested to the ANSI/SPRI/FM 4435 ES-1 and GT-1 standards — the certifications architects and spec writers look for on low-slope commercial roof edges. The tested line carries a 90 mph wind rating and 20-year warranty, and installs on any single-ply commercial roof system, not just Drexel's own metal panels.
