Prefab exterior decorative house molding .... typically used for roof line

Looking for prefabricated molding typically used for roofline ..... pieces comes in a variety of styles and sizes. I'm looking for ones that are 1.22 meters x 20 cm (one brand is sold at Home Depot) or 3.44 (approximately) meters x 20 cm) ... this brand/size is not sold at Home Depot, but I know is available in Guadalajara..... but where?

Thanks for any leads or information .....

You mean J-channel, flashing, drip channel, corner bead, even a picture would help; there is a guy on Guerrero in Chapala that does all kinds of sheet metal type stuff - range hoods, gutters, etc. If you took him a pic he could likely make it.
We bought a 1mx3m piece of sheet metal (it comes in various thicknesses), cut it and made our own flashing.

I've tried to copy and drag/drop a few photos from ads and it did not work ... it is Moldura. The traditional decorative molding that is around many of the local houses can be obtained in a prefab product. It is not sheetmetal. It is some sort of styrofoam with a cement coating.

I have found one place on-line that looks promising. It is Deco & Hogar in Zapopan. Their website is www.decohogar.com.mx I'm looking for pieces that come in either 1.22 m, 2.44 or wider/longer and 20 cm tall. I'll go to the Zapopan store. I'm just looking for some other resources, hopefully closer or some on-line resource. Thanks ... the sheet metal info you provided may come in handy for some things. thanks!!

I watched a guy put molding on a balcony edge today; entirely of concrete, no styrofoam in sight. Kind of like this https://www.amazon.com/Crown-Molding-Manufactured-Architectural-Polyurethane/dp/B00T344QTA
