Standard wall studs are 8' at 92 5/8" (94 1/8 for use with single top plate), 9' at 104 5/8", 10' at 116 5/8". The top of plate heights are 8' 1-1/8", 9' 1-1/8" and 10' 1-1/8".
Wood costs less.
Precut segments of wood are glued around a rod of graphite.
For a do-it-yourself floating shelf, the minimal requirements are a precut piece of wood (or a saw to cut the wood), a hammer and nails. Premade or precut floating shelves purchased at retail stores often come with at least some tools included.
A precut/milled wood stud is 2 inches by 4 inches before milling. When milled 1/4 of an inch is removed from all linear surfaces making it a 1 and 1/2 by 3 and 1/2 inch piece of lumber.
19 studs one every 18 inches
Basically the studs are the verticle bits of wood that take the load from the roof to the ground while a noggin is a horisontal bit of wood between the studs that prevent the studs from buckling and also add strength and support to the plasterboard

A length of round wood is called DOWEL.
Lumber yards and home improvement stores in the U.S. generally stock stud length 2x6's (92-5/8").
I would frame that part of the wall with wood.
Get a good stud finder and make a drawing of where the studs are. Get a good 'pin nailer' and compressor , then attach the sheets to the studs with 1. 9 " nails .
