Is 26 gauge better than 29 gauge for a roof?

Yes for durability. 26-gauge steel is thicker and holds up better to hail, foot traffic and denting than the 29-gauge panels common on sheds and barns. It also weighs more, so check your framing and purlin spacing.

What does Galvalume Bare mean?

It is unpainted steel with a zinc-aluminum coating instead of a paint finish. There is no color coat to peel, chalk or fade, and it develops a duller gray look over time.

Does the 40-year paint warranty apply to this panel?

The peel and chalk-or-fade warranty covers the SMP paint system on painted panels. This bare Galvalume version has no paint film, so that coverage does not apply to it.

How much area does one panel cover?

Net coverage is 36 inches wide once the ribs overlap. Multiply that by the panel length you order to get square footage, and add about 10 percent for waste and cuts.

Can I use it for siding as well as roofing?

Yes. The same panel is used for walls and interiors. On walls, fasten through the flats and keep the ribs running vertically for drainage and looks.

How are the panels fastened?

With exposed fasteners driven through the panel face into the purlins or girts. Use screws with sealing washers matched to the panel and do not overtighten, or the washer will distort and leak.
